Audis New A5 and S5 Cabriolet

2008-12-22T15:55:00Z

Dynamic and wonderful to look at, the new A5 Cabriolet is a real Audi, and an especially exciting one at that. The four-seater with the fabric top combines a sporty character with the fascination of open-top driving, refined comfort, and great everyday utility. Seven powerful engines, an agile suspension and a wide range of high-end options make the new Audi model the most attractive mid-range convertible. The top-of-the-line model of Audi’s new family of convertibles is the S5 Cabriolet. The engine of the S5 Cabriolet is the newly developed, supercharged three-liter V6 with gasoline direct injection. Prices start at EUR 37,300 for the 1.8 TFSI with 118 kW (160 hp) and six-speed manual transmission. Delivery of the first A5 Cabriolet models will begin in the second quarter of 2009.

Like all open-top Audi models, the new A5 Cabriolet too has a classic fabric top – which endows it with a striking silhouette of dynamic elegance. The lightweight softtop opens in 15 seconds – and closes in 17 seconds. The fully automatic open/close drive comes as standard. An acoustic top is optionally available, which reduces wind noise almost to the hardtop level.

When opened, the Audi A5 Cabriolet top folds down so effectively that very little trunk space is used up – leaving 320 liters (11.3 cu ft) of unused storage volume, clearly the best value in its field of competitors. The softtop compartment lowers itself automatically when the top is opened.

Equally useful is the fold-down rear seat backrest with the large pass-through between the luggage space and the interior, which increases the storage volume to a generous 750 liters (26.49 cu. ft.).

Automatic seat belt extenders round out the comfort in the interior. Neck-level heating is optionally available for the front seats. The optional leather seats are coated with a special layer to reduce solar heating. There is comfortable room for four persons. The refined ambience combines with exemplary ergonomics to convey an atmosphere of sporty elegance. Ultra-high-strength steels and selective reinforcements of the body ensure maximal rigidity and crash safety.

The A5 Cabriolet is being launched with three gasoline engines and two diesel engines, with power outputs ranging from 132 kW (180 hp) to 195 kW (265 hp). All five powerplants are fueled via direct injection; four of them use turbocharging. Available power trains include a six-speed manual transmission, the continuously variable multitronic, and the lightning-fast, seven-speed S tronic.

In addition to front-wheel drive, Audi also offers quattro permanent all-wheel drive for the higher-power engines. The innovative sport differential, which variably distributes the propulsive power between the rear wheels, is optionally available to make quattro even more dynamic and even safer.

Fascinating dynamics: Audi drive select
The perfect addition to this technology package is the Audi drive select vehicle dynamics system, which enables the driver to chose among three different engine maps controlling the characteristics of the fuel feed, the shifting points of the seven-speed S tronic and multitronic, and the mode of operation of the servotronic steering system. If the MMI operating system is installed, a fourth, freely programmable level is also available.

Audi drive select is only available in combination with one or more of three additional technologies – the sport differential, the adaptive control for the shock absorbers, and dynamic steering. This is an additional high-tech solution: Its superposition gear varies the gear ratio as a function of the driving speed by up to 100 percent.

The new Audi A5 Cabriolet features a rich array of equipment, including 17-inch alloy wheels, automatic air conditioning, and an audio system with a CD player. One of the highlights among the optional equipment is the third-generation MMI operating system, which provides many attractive navigation and entertainment functions.

As the dynamic top-of-the-line model of the new production series, the S5 Cabriolet occupies a very special position. Its three-liter TFSI – a V6 with turbocharger – unfolds its 245 kW (333 hp) and 440 Nm (324.53 lb-ft) of torque impressively: It responds tenaciously to the throttle and delivers excellent driving performance. The quattro drive, a sport suspension with 18-inch wheels and a number of special equipment details underscore the athletic power of the Audi S5 Cabriolet.

The exterior design
The Audi A5 Cabriolet combines Audi’s progressive styling with the fascination of an open-top car. The long engine hood, the sharp lines, the sweep of the shoulder contour, the elegantly curved surfaces, the large wheels, the distinctive front end, and the expressive tail all interact to create a sculptural, sensuous whole. The A5 Cabriolet is 4.63 meters (15.19 ft) long and 1.85 meters (6.07 ft) wide, but only 1.38 meters (4.53 ft) tall: the sportiest proportions in its class.

The styling of the front end is dominated by the single-frame grille, which is flanked by large air intakes. The exquisite design of the headlights makes them look like technical jewels. The daytime running lights of the optional xenon plus headlights consist of LEDs. An aluminum molding lends high gloss to the windshield frame.

The looks of the tail end are sharpened by horizontal lines, broad tail lights, straight tailpipes, and a distinctly colored diffuser insert. The trunk lid bears an unobtrusive spoiler lip. The xenon plus headlight option comes complete with LED taillights, which create a distinctive light pattern.

The convertible top
The fabric top with the large glass rear window fits smoothly into the design profile. This is one of several reasons why Audi preferred it to a folding steel roof. What’s more, its construction is much lighter in weight, which reduces the overall weight of the Cabriolet and lowers its center of gravity. The outer skin of the top is available in a choice of four colors, the inside in three.

The softtop consists of three layers. The intermediate layer is a cushioning pad. In the optional acoustic top, which reduces wind noise almost to hardtop level, this is replaced by a foam layer up to 15 millimeters (0.59 in) in thickness. The acoustic top comes with a ceiling light for the rear seat – a solution usually only found in the topmost convertible luxury segment.

In both versions, a hydraulic pump and four operating cylinders that move the top are actuated when a pushbutton on the central console or on the optional remote access assistant is depressed. It takes 15 seconds to open the top, 17 seconds to close it. Both actions can also be actuated while driving at up to 50 km/h (31.07 mph) – which makes driving much more comfortable.

When opened, the top is retracted underneath a fixed cover, where it is folded down into an extremely compact shape. Its storage compartment, which automatically lowers itself into the trunk space, only takes up a few centimeters in height – and only 60 liters (2.12 cu ft) of the 380 liters (13.42 cu ft) of luggage space. The remaining 320 liters (11.3 cu ft) with the top open are by far the best value among comparable vehicles. What’s more, the low position of the loading lip makes loading and unloading easier. The wind deflector, which is supplied as standard, can be stored in the spare-wheel well to save space.

A very convenient feature in the Audi A5 Cabriolet are the split folding rear seat backrests. They can be easily unlocked by actuating levers in the trunk and drop automatically onto the seat cushions. The standard pass-though is 70 centimeters (27.56 in) wide. The loading space behind the front seatback is 1.76 meters (69.29 in) long, providing a total storage volume of 750 liters (26.49 cu ft).

The body
As is typical of Audi models, the A5 Cabriolet has an extremely rigid body. This is a prime reason for its precise driving performance, its high comfort level, and its maximized crash safety.

In the construction of the body-in-white, several innovative technologies are used. A prime example are the ultra-high-strength steels with their extremely high tensile strength, which Audi manufactures in-house using hot forming. The front fenders of the A5 Cabriolet are made of aluminum to lower the weight and to optimize axle load distribution. An enclosed underbody improves the airflow and thereby the fuel efficiency.

A whole array of additional reinforcement parts compensates for the absence of a solid roof. They are located in the front section, in the side skirts, in the windshield frame, and in the rear section. Located between the interior and the luggage section is the rollover protection. When a rollover threatens, spring-loaded aluminum braces are raised behind the rear seat headrests. Head and chest sidebags provide protection in the event of a lateral impact.

The interior
With its generous wheelbase of 2.75 meters (9.02 ft) and the longest interior in its class, the Audi A5 Cabriolet has plenty of room for longer trips. That’s also true for the rear seats, which can be optionally divided by a center console with two cup holders.

Elegance in flowing lines, functional ergonomics, and top-quality craftsmanship are the principal characteristics of the interior – and this too is typically Audi. The teardrop-shaped settings of the instruments have already become modern classics. The centrally mounted onboard monitor is standard equipment. The formed-plastic console focuses on the driver. Flowing lines link it to the central tunnel and the door linings. If the customer has ordered either one of the two navigation systems it comes with the highly convenient MMI operating system – the best solution on the market.

The low standard seats provide excellent control and support. Using seatbelts is facilitated by electric seat belt extenders. Special solutions are available as alternatives: firm sport seats, electric seat adjustment and heating – as a separate option also for the back seats.

In the climate-controlled comfort seats, small fans and an automatic auxiliary heater ensure luxurious comfort. This option provides neck-level heating – ducts on the topside of the seatback emit warm air that keeps the back of the head and neck warm. With its three-level control, the headroom heater is also available for sport seats. It prolongs the open-air season in the Audi A5 Cabriolet.

Another special feature is provided in the optional leather upholstery: a special coating inhibits solar heating while the Cabriolet is parked in the sun with the top down. This coating reflects infrared radiation and thus lowers the surface temperature by up to 20 degrees Celsius. Audi offers a choice of several seat coverings up to and including Fine Nappa leather. Inlays come as standard in Micrometallic platinum; aluminum and three different kinds of wood are available as options.

The engines
In the propulsion system of the A5 Cabriolet too Audi has consistently relied on innovative technologies: All five engines – the two TDIs and the three gasoline engines – use direct injection. They are impressive evidence that, at Audi, efficiency and dynamics go together and are interdependent.

The most powerful gasoline engine in the Audi A5 Cabriolet is the 3.2-liter FSI. It operates with the innovative Audi valvelift system, which varies the lift of the intake valves in two stages. As a result, the gas exchange improves and the throttle can be left open more often, minimizing throttling losses – which in turn boosts the torque and the power output while reducing fuel consumption. The V6 delivers up to 195 kW (265 hp) as well as 330 Nm (243.4 lb-ft) between 3,000 and 5,000 rpm. With front-wheel drive and multitronic it accelerates the A5 Cabriolet in 6.9 seconds to 100 km/h (62.14 mph) – and up to a top speed of 246 km/h (152.86 mph). Its average fuel efficiency is an impressive 8.6 liters/100 km (27.35 US mpg). An optional alternative is quattro all-wheel drive, combined with the new seven-speed S tronic.

The 2.0 TFSI likewise attests to Audi’s leadership position in engine design. This four-cylinder engine also uses the Audi valvelift system – but here it acts on the exhaust valves, with similar advantages as in the V6. Audi sells the two-liter turbo in two versions. In the entry-level version, which comes with front-wheel drive and multitronic, it delivers up to 132 kW (180 hp) and 320 Nm (236.02 lb-ft) from 1,500 to 3,900 rpm. This version completes the standard sprint in 8.9 seconds and has a top speed of 219 km/h (136.08 mph). Average fuel efficiency is an excellent 7.4 liters per 100 km (31.79 US mpg).

The more powerful version of the 2.0 TFSI delivers 155 kW (211 hp) as well as 350 Nm (258.15 lb-ft) between 1,500 and 4,200 rpm. It is available with three powertrain versions: with the quattro drive package and the seven-speed S tronic, and with front-wheel drive and either multitronic or manual transmission. In the latter version the A5 Cabriolet reaches 100 km/h (62.14 mph) in 7.5 seconds and has a top speed of 241 km/h (149.75 mph). Its average fuel efficiency is an impressive 6.8 liters per 100 km (34.59 US mpg).

The two V6 TDIs also set the standards in their class. With their enormous torque and consistent running smoothness they represent the leading-edge sportiness of Audi TDI technology. The three-liter engine generates 176 kW (240 hp) and applies 500 Nm (368.78 lb-ft) of torque to the crankshaft between 1,500 and 3,000 rpm. The sprint from zero to 100 km/h (62.14 mph) takes 6.4 seconds. Top speed is 247 km/h (153.48 mph). This top-of-the-line diesel, which powers all four wheels via the seven-speed S tronic, is content with an impressive average of 6.8 liters/100 km (34.59 US mpg).

The second TDI in the program is even thriftier. The 2.7-liter powerplant with 140 kW (190 hp) and 400 Nm (295.02 lb-ft) between 1,400 and 3,500 rpm consumes a mere 6.3 liters/100 km (37.34 US mpg)*. The smaller V6 diesel comes with front-wheel drive and manual transmission. It goes from zero to 100 km/h (62.14 mph) in 8.6 seconds; 230 km/h (142.92 mph) is its top speed (preliminary values).

The transmission
Audi provides a choice of three different transmissions for the A5 Cabriolet. The 2.0 TFSI with 155 kW (211 hp) comes with a six-speed manual transmission as standard, which excels in its short shifting travels and high operating precision. Both the two-liter engine and the 3.2 FSI are available with the multitronic continuously variable automatic transmission as an option, which combines smooth operation with high efficiency and a fuel-saving transmission ratio. For a dynamic driving style the multitronic is available with a sport program and a manual mode with eight fixed speeds.

For the more powerful version of the 2.0 TFSI and for the 3.2 FSI, the seven-speed S tronic is available as an option; in the 3.0 TDI it is standard equipment. This new high-tech dual-clutch transmission changes gears in a few hundredths of a second, and so smoothly that the driver hardly notices it. What’s more, it is highly efficient and fuel-saving. The driver can let the seven-speed S tronic shift automatically or interact, if desired, via rocker switches on the steering wheel.

The seven-speed S tronic has been designed for use with the quattro permanent all-wheel drive. It is optionally available for the high-end diesel series and for the two powerful gasoline engines. The quattro drive system is dynamically designed – during normal driving it distributes the forces in a 40:60 ratio between the front and the rear. If one wheel skids, a center differential that operates purely mechanically transfers most of the power to the axle with the better traction.

The new sport differential makes the driving dynamics of the quattro drive even more fascinating. This innovative control system steplessly distributes the propulsive torques among the rear wheels depending on the driving situation.

This form of torque control makes the steering response of the A5 Cabriolet even more spontaneous and direct and further improves the vehicle’s stability. Transverse acceleration is further improved while understeering or oversteering is completely prevented.

The chassis
The Audi A5 Cabriolet leads its class in all relevant sporty criteria – steering response, stability and agility – yet it provides a very smooth ride. The reason for these strengths is the perfect distribution of axle loads. The front axle is located far forward in the front section – a configuration made possible by an unusual solution: the differential is mounted in front of the clutch or torque converter.

The chassis design too is technologically advanced: The front wheels are mounted on a five-link axle. The front axle support is firmly bolted to the body in order to maximize rigidity. The steering forces are transmitted to the wheels directly via the steering box, which is mounted very low within the chassis. The hydraulic rack-and-pinion steering provides a very responsive and highly precise connection to the road. Optionally available is the servotronic, which adjusts its support level to the driving speed.

The rear-wheel suspension of the Audi A5 Cabriolet is supported by a trapezoidal-link axle, which combines a smooth ride and maximum driving stability. The essential parts of both the front and the rear suspension are made of aluminum. The large brakes ensure powerful deceleration and react very precisely to the degree of pedal pressure. 16-inch or 17-inch aluminum wheels are standard, depending on the engine version. Optionally available from Audi and quattro GmbH are 18-, 19- and 20-inch wheels.

Another high-tech feature in the new A5 Cabriolet is the Audi drive select vehicle dynamics system. It influences the characteristics of the fuel feed, the speed change points of the seven-speed S tronic, and the operating mode of the servotronic steering system. The driver presses a key to select a comfortable, intermediate, or dynamic operating mode for these subsystems. If the vehicle is equipped with a navigation system – and the MMI operator control that comes with it – a fourth engine map is provided, which the driver can program to suit.

Audi drive select is only available in combination with one or more of three additional technologies – the differential, the adaptive shock absorber control, and dynamic steering. Its superposition gear varies the gear ratio by nearly 100 percent as a function of the driving speed. The dynamic steering operates directly in city traffic. In highway driving it uses a more indirect ratio. To maximize driving safety, it cooperates closely with the ESP stabilization program – at the handling limits it keeps the A5 Cabriolet on course by lightning-fast small interactions.

The equipment
The Audi A5 Cabriolet comes with an impressive array of standard equipment. This includes a fully automatic convertible top, 16-inch or 17-inch alloy wheels, a fold-down rear seatback with a large pass-through, and automatic air conditioning; the chorus audio system comes with integral CD player. Electric seat belt extenders and an electromagnetic parking brake are also standard.

Further luxury is available in the options: The adaptive light option combines xenon plus headlights with dynamic cornering lights; the high-beam assistant changes automatically between low beam and high beam. The advanced key provides keyless access and allows starting the car as well as opening and closing the top remotely. The deluxe automatic air conditioning manages the temperature separately in three zones in the vehicle. The acoustic top further lowers the wind noise level. And the climate-controlled comfort seat in combination with the neck-level heating creates a perfectly tempered environment.

When it comes to the chassis, the program is complemented by the Audi drive select system, the sport differential, and two conventional sport suspensions. The S line sport package plus combines the stiff set-up with performance features such as 10 millimeters less body height, 18-inch wheels and 245/40 tires with a package of special details for the interior. The S line exterior package, on the other hand, endows the vehicle with an especially dynamic look.

Further highlights are the two infotainment systems MMI navigation and MMI navigation plus – members of an entirely new equipment generation. Even the lesser model includes navigation imaging featuring 3D color graphics, a versatile reader for memory cards, and a DVD drive. Optionally available from Audi is a module for digital radio reception, a Bluetooth interface for the mobile phone, and an interface for full integration of the iPod.

The top version comes with exclusive technologies: an especially high-definition monitor, a big hard drive for music files and addresses, plus a special joystick function for the MMI control unit. With refinements such as a Bang & Olufsen sound system or a digital TV tuner, the MMI navigation plus can be turned into a high-end media center.

Innovative assistant systems from the luxury class make driving in the A5 Cabriolet even more supremely relaxed. Audi optionally equips its open-top four-seater with high-tech solutions including adaptive cruise control, Audi side assist and Audi lane assist. They control the distance from the vehicle in front and assist in staying in lane or in changing lanes. The luxury-class Audi parking system advanced uses a rearview camera to display the area behind the vehicle on the onboard monitor.

The Audi S5 Cabriolet
The top-of-the-line model of the new Cabriolet production series from Audi is the S5 Cabriolet. The letter “S” stands for Sport – for dynamics, performance and power, but also for amazing efficiency.

The Audi S5 Cabriolet’s engine is a newly developed, supercharged, three-liter V6. The pressure in the 3.0 TFSI is generated by a mechanical supercharger – with impressive results: The power output tops out at 245 kW (333 hp), the torque between 2,900 and 5,300 rpm remains constant at a generous 440 Nm (324.53 lb-ft). The powerful thrust and the spontaneous, aggressive response make for a fascinating driving experience. The S5 Cabriolet is catapulted in 5.6 seconds from zero to 100 km/h (62.14 mph) and accelerates up to a preset top speed of 250 km/h (155.34 mph). Yet at 9.6 liters* per 100 km (24.5 US mpg), its fuel efficiency is highly impressive (preliminary values).

Standard equipment of the Audi S5 Cabriolet includes the servotronic, the seven-speed S tronic and the quattro drive system package. The sport differential is optional. A sport suspension keeps the body close to the road. The 18-inch cast aluminum wheels are equipped with 245/40 tires. The black brake calipers are emblazoned with S5 emblems. The acoustic top, xenon plus headlights, electrically adjustable sport seats with Alcantara leather upholstery, and a multifunction sport steering wheel are also standard equipment.

Diverse design features contribute to a distinctively sporty styling, including modifications at the lower front and back panels, at the air intakes and at the tailpipes. In the interior, special seat upholstery, door sill trims and inlays in matt brushed aluminum underscore the high-quality, dynamic style of the high-end model. The pointers of the instruments are illuminated white to contrast with the gray scales.

It's official - V10 Audi R8

2008-12-22T15:38:00Z

Audi is launching the next variant of its top-of-the-line model. With the R8, the brand has established itself at the forefront of high-end sports cars from the very start – and now comes the R8 V10. Its 5.2-liter, ten-cylinder engine churns out 386 kW (525 hp) and 530 Nm (390.91 lb-ft) of torque, which makes for breathtaking performance. With superior Audi technologies such as quattro all-wheel drive, the lightweight aluminum body, the innovative all-LED headlights, and its striking design, the R8 V10 takes pole position against the competition.

The R8 V10 is the result of cumulative know-how from Audi’s string of Le Mans victories. Its naturally aspirated engine combines racing technology such as dry sump lubrication with FSI gasoline direct injection. The ten-cylinder design is the perfect synthesis for impressive top performance, mighty pulling power, and low weight. Starting in 2009, this engine will also prove its potential on the world’s racetracks – in the new R8 racing car Audi is developing for customer teams in conformance with the GT3 rules.

The V10 engine in the production sports car will be almost identical in construction to the one in the racing version. Its displacement is 5,204 cc, at 6,500 rpm it delivers 530 Nm (390.91 lb-ft) of torque, at 8,000 rpm its power tops out at 386 kW (525 hp).

The specific power output is 100.9 hp per liter of displacement – and each hp has to propel only 3.09 kilograms (6.91 lb) of weight, because the Audi R8 V10 in the version with the six-speed manual gearshift weighs only 1,620 kilograms (3571 lb). The engine accounts for 258 of these kilograms (569 lb) – that’s only 31 kilos (68 lb) more than the V8.

The Audi R8 5.2 FSI quattro rockets from zero to 100 km/h (62.14 mph) in 3.9 seconds. In the version with the sequentially shifting R tronic it reaches 200 km/h (124.27 mph) in another 8.1 seconds. Even then its propulsive power hardly lessens: it’s sufficient to reach a top speed of 316 km/h (196.35 mph). The immense force, the spontaneity and the thrust of the acceleration, plus the sound of the engine – all these impressions coalesce into a breathtaking sports car experience. The V10 plays a concert with growling bass tones and powerful high notes, which grows into a grandiose fortissimo as the engine revs up. This sonorous acceleration doesn’t reach its limit until 8,700 rpm.

The 5.2-liter powerplant uses direct injection according to the FSI principle developed by Audi. A common rail system injects the fuel into the combustion chambers with up to 120 bar of pressure. Direct injection reduces the susceptibility to knocking and provides a certain amount of cooling through the evaporation of the fuel, which in turn supports a high compression ratio of 12.5:1. This in turn contributes to superior performance and improves fuel economy. The R8 V10 with R tronic gets by on an average of 13.7 liters per 100 km (17.17 US mpg).

For maximum dynamics: low center of gravity engine
The technical refinements of the long-stroke ten-cylinder engine include dry sump lubrication, which allows the engine to be mounted low within the chassis. The wide cylinder angle of 90 degrees also makes for a low center of gravity. The crankcase is a high-strength aluminum-alloy casting produced in a complex process. The connecting rods are made of forged steel, the pistons of aluminum. The four camshafts are chain-driven and each is adjustable through 42 degrees. This provides great latitude in controlling the valve timing. In combination with the straight, flow-optimized ducts of the intake manifold, this improves the charge throughout the entire speed range.

The R8 5.2 FSI quattro has a six-speed transmission. A precise and smooth-shifting manual transmission comes as standard equipment. The sequential R tronic is available as an option. The high-tech gearshift conveys an authentic racing feel – with the rocker switches at the steering wheel and the short shifting times of usually less than one-tenth of a second. When the driver actuates the Launch Control program by pressing a button, the R8 V10 takes off in a vehement quick-start with electronically controlled tire slip – both with the R tronic and with the manual transmission.

A contributing factor to the wide lead in traction and driving safety of the Audi R8 V10 over the competition is quattro all-wheel drive – it’s the superior technology especially for a high-performance sports car. Four powered wheels get more grip than two. They enable the driver to step on the gas sooner when coming out of a curve. It’s not only the traction that benefits, but also the transverse dynamics and the stability.

44 to 56 percent – the ideal axle load distribution
The Audi R8 chassis offers both dynamic performance and astonishing levels of comfort on long distances. This high-performance sports car from Audi eagerly responds to any steering action with instant ease, achieves lateral acceleration of up to 1.2 g, and handles any situation with superb driving safety. Its mid-engine design provides an ideal axle load distribution of 44 to 56 percent.

The wheel suspensions on dual aluminum wishbones front and rear – a classic racing technology – are optimized for neutral self-steering characteristics. Even more than in the eight-cylinder R8, this setup is designed for maximum performance. 19-inch wheels equipped with tire pressure monitoring display are standard equipment. Their 10-spoke Y design is exclusive to the R8 V10. Tire sizes are 235/35 front and 295/30 rear.

The car features a high-end damper technology as standard: Audi magnetic ride adapts the characteristics of the suspension in milliseconds to the nature of the road surface and to the driving style. Suspended in the oil of the shock absorbers are tiny magnetic particles which, when a voltage is applied, rearrange themselves so as to slow down the flow of oil through the valves.

In the R8 V10, deceleration is provided by an extremely muscular braking system – eight brake pistons at the front and four at the rear grasp the brake disks, which are ventilated and perforated to ensure unimpeded heat transfer. The brake disks on the front axle have a diameter of 380 millimeters (15 in); the rear discs span 356 millimeters (14 in).

The R8 5.2 FSI quattro is optionally available with a ceramic brake system whose disks are made of a composite material containing high-strength carbon fibers and abrasion-resistant silicon carbide. These are especially light: their combined weight is nine kilograms (19.84 lb) less than the weight of equivalent steel disks. The ceramic brakes can easily cope with the harsher requirements of racing, won’t corrode, and have a typical service life of 300,000 kilometers (186,400 miles). Their calipers are painted charcoal gray and emblazoned with the inscription “Audi ceramic”.

Typically Audi: Sharp lines and an elegantly curved roof
The wide, full shape of the R8 5.2 FSI quattro seems to hug the road. The brawny proportions and prominent wheel wells underscore its potential. The high-precision styling of the lines and the elegant curve of the roof are typical Audi features. A continuous contour optically connects the front, the wheel wells, the sides and the rear. Located well forward, the cab visually expresses the mid-engine design. The vertical air scoops (sideblades) on the sides are also indicative of the engine location. The massive aluminum gas cap is mounted flush within the right sideblade.

The design of the Audi R8 has already impressed experts, as evidenced by the double victory in the “World Car of the Year Awards 2008”. In the ten-cylinder model, the styling has been sharpened up even more.

The front air inlets, which feed air to the coolers, and the lip of the front apron are painted in high-gloss black. The number of cross-braces has been reduced from four to two. The vanes of the single-frame grille have a striking chrome finish.

A very distinctive highlight of the R8 V10 are the all-LED headlights as standard equipment. Audi is the world’s first automaker to use LEDs for the high beam, low beam, daytime running lights, and turn signals. Each headlight integrates 54 of these high-tech light sources. With a color temperature of 6,000 Kelvin the LED light closely resembles daylight, which is less tiring to the eyes in night driving. Further advantages of the LEDs include brilliant illumination, low energy consumption, and a virtually unlimited service life.

Special details also distinguish the body of the R8 V10. Its sideblades are more accentuated than in the eight-cylinder version. The side sills are more striking and wider; the exhaust grilles at the rear windows have a matt aluminum look. Through the large rear window, the ten-cylinder engine is clearly visible in its consummate technical beauty.

When in motion, this Audi high-performance sports car creates a downforce that keeps it in firm contact with the road – thanks to a rear spoiler which deploys automatically at 100 km/h and the fully enclosed underbody, which terminates in a sharply upward-curved diffuser. The dominant color at the rear end is high-gloss black, including the settings of the LED tail lights. The air outlets at the rear end also have only two cross-braces, and the exhaust system terminates in two large oval tailpipes.

Audi sets the example – in body weight and rigidity
The body of a sports car must be especially lightweight and rigid. Audi meets these requirements with the technology of the Audi Space Frame (ASF) and its high-tech aluminum construction. The body-in-white of the R8 V10, which includes an engine frame made of ultra-light magnesium, weighs only 210 kilograms (463 lb), and the quality of its lightweight design – the relation of weight to torsional rigidity – is the best in the sports car segment. The body is composed of profile extrusions, sheet aluminum and very complex gusset castings, all held together by 99 meters (325 ft) of welding seams, 782 rivets, and 308 special screws.

The interior of the R8 V10 provides a unique racing ambience at the luxury level. Its dominant element is the so-called monoposto – a wide arc that contains the steering wheel and the cockpit. As always in an Audi, the workmanship is of the highest quality. The surfaces of the dashboard and doors are lined with fine materials and adorned with precisely stitched decorative seams. Many customizing solutions are available: Audi supplies leather in a wide range of colors, packages with a carbon and piano-lacquer finish, or a made-to-measure luggage set. quattro GmbH, which has developed and is producing the R8 V10, also provides solutions for unconventional requirements.

The great everyday utility of the Audi R8 V10 is based in part on its spacious interior made possible by the long wheelbase of 2.65 meters (8.69 ft). Drivers and passengers of any size will always find a perfect sitting position. Visibility too is surprisingly good. Slender hinge pillars optimize the obliquely forward field of view. Another advantage for convenient everyday use is the luggage space: 100 liters (3.53 cu ft) fit under the front hood, another 90 liters (3.18 cu ft) can be stowed behind the seats. There is also room for two golf bags.

The Audi R8 5.2 FSI quattro combines its colossal performance with a generous complement of standard equipment. Highlights include heatable seat covers made of Fine Nappa leather, a driver information system, the navigation system plus and the Bang & Olufsen sound system along with deluxe automatic air conditioning and an alarm system. The instruments and the gearshift knob are decorated with red rings; the footrests and the rocker switches of the R tronic have an aluminum finish.

The list of options includes other highly attractive features – such as the Audi parking system advanced with its integrated rearview camera or numerous Audi exclusive customization options. Various leather packages provide a luxurious touch, while the bucket seats from the Audi exclusive program bring a highly concentrated racing atmosphere into the R8 V10.

Audi Goes Frugal with the A4 Concept e

2008-10-02T19:56:00Z

Efficiency is the way into the future – Audi is introducing the current state-of-the-art for its fuel-saving technologies at the Paris Auto Show. The A4 TDI concept e technology concept has the agile handling characteristics typical of the A4, but requires just 3.99 liters of fuel per 100 kilometers (58.95 US mpg). This exemplary result was possible through the concentrated use of innovative efficiency modules.

Audi is committing major resources in order to continue improving fuel efficiency and reducing emissions. The brand is introducing a trend-setting technology concept at the Paris Auto Show: the A4 TDI concept e offers the typically agile experience of driving an Audi, yet it uses just 3.99 liters of fuel per 100 km (58.95 US mpg), which corresponds to a CO2 output of only 105 grams per km (168.98 g/mile). With this near-production study, Audi demonstrates the great potential of the technologies in its modular efficiency system.

The powertrain of the Audi A4 TDI concept e uses a direct-injection TDI engine with an output of 88 kW (120 hp) and 290 Nm (213.89 lb-ft) of torque. It propels the sedan from 0 to 100 km/h (62.14 mph) in 10.7 seconds, and tops out at 206 km/h (128 mph). An entire array of details – from soft springs on the intake valves to a new thermal management system – improves fuel efficiency. Intelligent technologies are used in the engine’s functional environment as well, such as on the fuel pump and on the automatic air conditioning’s compressor.

The recuperation system is another fundamental component for improving fuel efficiency. It recovers power when braking and coasting to a stop, and temporarily stores it in a battery. A start-stop system switches the engine off when the vehicle comes to a standstill. Magnesium was used to reduce the weight of the six-speed transmission, which received an insulating cover for faster warm-up and modified gear ratios.

Audi uses an electromagnetic servo assembly for steering; electrically actuated brakes are fitted at the rear. The 225/45 R17 tires have been optimized for road resistance. Sophisticated fine-tuning measures have improved the aerodynamics of the body. Two types of support are at the driver’s fingertips: he can either call up an economy training program, or have the navigation system calculate the most fuel-efficient route to his destination.

Paris 2008: Audi A1 Sportback Concept

2008-10-02T19:41:00Z

Audi is presenting another version of the innovative hybrid technology in the drive unit for the A1 Sportback concept. At work under the hood is a 1.4-litre TFSI engine developing 110 kW (150 hp), whose power is directed to the front wheels by means of the S tronic dual-clutch transmission. A 20 kW (27 hp) electric motor integrated in the drive train is able to deliver up to an additional 150 Nm of torque (110.63 lb-ft) when the vehicle is accelerating. During the boosting phase, i.e. when the TFSI engine and electric motor operate simultaneously to enable a sporty driving style, the two power packs deliver impressive propulsion. The tried-and-tested front-wheel drive – supplemented by the newly developed, ESP-controlled active front differential lock – ensures optimum transfer of power to the road.

The electric motor is furthermore capable of powering the vehicle alone for zero-emission driving in residential areas, for instance. The capacity of the lithium-ion batteries gives the vehicle a range of up to 100 km (62.14 miles) in pure electric mode; the motor can be recharged from any power socket. The automatic start/stop facility, energy regeneration and phases of purely electrical operation reduce the fuel consumption and emissions of the Audi A1 Sportback concept by almost 30 percent compared to when it is running on the combustion engine alone. Despite its sporty performance, with acceleration of 0 to 100 km/h (62.14 mph) in 7.9 seconds and a top speed of 200 km/h (124.27 mph), the Audi A1 Sportback concept requires only 3.9 liters of premium fuel per 100 km (60.31 US mpg); CO2 emissions are an efficient 92 g/km (148.06 g/mile).

Exterior

The difference is not down to the two extra doors alone: the styling of the five-door concept vehicle is a consistent development of the three-door study, the Audi A1 project quattro from the year 2007. Surfaces and lines are distinctly tauter and more masculine.

The basic proportions, with a high vehicle body and a flat window area bordered by a coupe-like roof line, produce a virtually classic look for a vehicle bearing the four rings. The rear end is rounded off by a two-part spoiler with a striking centre groove, integrated into the rear window.

The side-on view presents another typical coupe attribute in the form of doors with frameless windows and a glass-covered and thus homogeneously integrated B-pillar. The bold segmentation of the study's side paneling with its gently rising shoulder line accentuates the styling.

The shoulder line of the Audi A1 Sportback concept with its Daytona Grey paint finish is a new interpretation of yet another trademark feature of the current Audi design. Here, the prominent double lines continue around the entire vehicle as a curvaceous band that links the front end – from which it seems to emerge – with the vehicle's tail, which rises to create a slightly wedge-shaped effect.

The aerodynamically designed single-frame grille indicates the sporty ambitions of the study, which are further emphasized by the flared fenders – a tribute to the legendary Ur-quattro design and the current Audi RS 6.

The design of the three-dimensional main headlights in innovative LED technology is especially eye-catching. The completely new styling underlines yet again the amount of freedom that this technology has afforded to designers. All light functions – low‑beam and high-beam headlights, daytime running lights and turn indicators – have been located in one flat housing, in concentrically arranged, parallel and squared-off strips.

The layout, with light segments of varying sizes – the low beam taking up most space – completely changes the character of the front section, the “face” of the A1 Sportback concept.

The rear lights, too, continue this theme and combine the function of tail and brake lights, turn indicators, reversing and rear fog lights into an unmistakable design. The interplay of acute and obtuse angles and the clear and colored glass areas create a particularly dynamic look. A large-dimensioned, transparent cover over the entire width of the vehicle additionally combines both light units and emphasizes the horizontal design of the rear.

Like the three-door version, the body of the four-door Audi A1 Sportback concept makes optimum use of the small road surface area available to a vehicle from the premium compact class. Measuring 3.99 m long (13.09 ft) and 1.75 m wide (5.74 ft) with a wheelbase of 2.46 m (8.07 ft), it succeeds in combining sporty looks with impressive economy of space thanks to its short overhangs. The transverse installation of the engine also has a significant role to play in this respect. The third dimension of this compact, sporty car – i.e. the height – comes in at 1.40 meters (4.59 ft).

A4 Driving Challenge For The Apple iPhone - v2 Update!

2008-09-30T12:33:00Z

After the rather dismal first release of the only mainstream car manufacturer backed game for Apple's iPhone, Audi, it would seem, have listened to the feedback of iPhone users across the world. The new update of their Audi A4 Driving Challenge game, which uses the tilt function of the iPhone to control the direction of driving sees a lot of the initial issues users had with the game fixed. Gone are the skittish controls which would see players zig zagging across the sometimes narrow track. In their place is an updated control which is a lot more fluid and, more importantly, has a sensitivity control within the games setting menu to further fine tune players reactions.

Also added are three extra bonus cars; Audi A4 2.0T, Audi A4 3.2 V6 Quattro and for those speed freaks amongst us - the Audi R8 - which are unlocked by completing various time locked bonuses There are four tracks in all, each with an increasing step up in difficulty.

Graphically there are also some detail changes such as a heads up map display which relays the players position on track - which comes in really handy as you can anticiapte corners. To counter the issues of not knowing where the track is going! To help judge the steering angle a neat little flat bottomed steering wheel is also added across the display bar, which reacts depending on how much turn you feed the iPhone via the tilt facility. Great!

The in game menus and track selection screens have all had a make over, too.

With the changes in place the game now has that 'just one more go' feeling - which is always a good sign for a pick up and go game like the A4 Driving Challenge.

The game update is available from Apple's iPhone App Store, located on the home screen of your iPhone. Alternatively you can also download the update from iTunes on your PC/Mac.

The New Audi S4 and S4 Avant - First Look

2008-09-23T08:48:00Z

Audi is introducing its new sporty top models in the midsize class – the S4 and the S4 Avant. Their engine, a three-liter V6 with direct fuel injection and mechanical turbocharging, delivers a powerful 245 kW (333 hp). It accelerates the S4 to 100 km/h (62.14 mph) in just 5.1 seconds, but on average only uses 9.7 liters of fuel per 100 km (24.25 US mpg). The quattro permanent all-wheel drive system transfers its power to the road in style, which is then converted by the sport suspension into dynamic handling. Upon request, Audi can equip the new S4 and S4 Avant with innovative technologies that further increase their lead over the competition. The seven-speed S tronic changes gears with lightning speed, and the new sport differential distributes the torque as needed between the rear wheels. The new Audi S4 will be unveiled to the public for the first time at the Paris Auto Show from October 2 to 19.

The heart of the new S4 and S4 Avant is a completely redesigned engine. The 3.0 TFSI, the newest member of the Audi V-engine family, is an outstanding example of how the brand with the four rings blends performance and efficiency. The V6 generates its power from a displacement of 2,995 cc, is equipped with a supercharger, and delivers 245 kW (333 hp). The sedan sprints to100 km/h (62.14 mph) in just 5.1 seconds, and the Avant in 5.2 seconds: they both have an electronically governed top speed of 250 km/h (155.34 mph).

The “T” in the 3.0’s TFSI nomenclature no longer merely stands for “turbo”, but rather for the concept of supercharging in general – extensive testing on the big V6 has proven the superiority of mechanical charging. In conjunction with direct injection it is far superior to twin turbochargers, both in terms of packaging and of starting performance and responsiveness.

The compressor is so compact that it easily fits inside the 90-degree V of the cylinder banks, in place of the intake manifold. Two four-vane rotary pistons counter-rotate inside the turbocharger at up to 23,000 rpm. Two charge-air coolers are integrated into the housing and are connected to a separate coolant circuit. An impressive array of measures keeps the noise generated by the compressor to a minimum.

The engine-driven belt that powers the mechanical charger provides full thrust right from idling speed. The 3.0 TFSI delivers its maximum 440 Nm (324.53 lb-ft) at 2,500 rpm and maintains this constantly until 4,850 rpm. In fourth gear, the vehicle accelerates from 80 to 120 km/h (49.71 to 74.56 mph) in just 4.4 seconds. Thanks to the extremely short gas paths, the sonorous, supercharged V6 responds spontaneously to the throttle, even more so than a naturally aspirated engine of the same displacement.

Furthermore, the new 3.0 TFSI achieves exemplary fuel efficiency. On average, the sedan uses 9.7 liters of fuel per 100 km (24.25 US mpg), and the Avant 9.9 liters per 100 km (23.76 US mpg) – an improvement of 3.4 liters (26 percent) compared with its predecessor. The Audi technology of gasoline direct injection was what made this great efficiency possible in the first place. Unlike conventional concepts, it allows the compressor to be located behind the throttle valve. In view of the low density of the intake air at loads below supercharging level and when coasting, its rotors are free-running and the amount of power required to drive them is low.

Dynamism and efficiency: The new seven-speed S tronic

The V6 power in the new S4 and S4 Avant flows into a six-speed transmission, fitted as standard, which shifts quickly and precisely. As an option, Audi offers a state-of-the-art dual-clutch transmission – the seven-speed S tronic is extremely dynamic and highly efficient. The driver has the option of driving in fully automatic mode or selecting the gears with paddles on the steering wheel or directly with the shift lever – all of which provide impressively quick gearshifts. The gearshift feel is dynamic, comfortable and very precise – typically Audi.

The seven-speed S tronic consists of two separate transmissions and uses two multidisk clutches that control the various gears. The large K1 clutch guides the power via a solid shaft to the pinions for gears 1, 3, 5 and 7. A hollow shaft rotates around the solid shaft; it is connected to the compact K2 clutch, which is integrated within its larger counterpart and controls the pinions for gears 2, 4, 6 and reverse gear.

Both transmission structures are continuously active, but only one is powered at a time by the engine. For example, when the driver accelerates in third gear, the fourth gear is already engaged in the second transmission structure. The shifting process takes place as the clutch changes – K1 opens and K2 closes with lightning speed. This process takes only a few hundredths of a second and is completed without interrupting traction. It is so comfortable and smooth that the driver hardly notices it.

The seven-speed S tronic is designed for maximum efficiency. It operates with very high efficiency and its intelligent control system maximizes fuel economy in automatic mode. With its wide gear ratio spread of 8.0:1 the seven-speed S tronic easily exploits the tremendous power and superior torque of the 3.0 TFSI.

The quattro permanent all-wheel drive system transfers power to the road with supreme ease. Under regular driving conditions, it sends 40 percent of its torque to the front wheels and 60 percent to the rear wheels – a slightly rear-biased, sporty characteristic. Where necessary, it can vary distribution within fractions of a second.

The quattro drive system ensures safe self-steering characteristics, high stability and excellent traction in comparison with rear-wheel-drive competitors.

Customized torque distribution: The sport differential with Audi drive select

The new, active sport differential ideally complements the quattro drive system and lends it even greater fascination. When the steering wheel is turned or the car accelerated in a corner, power is redirected in a controlled manner to the outer rear wheel, literally pushing the vehicle through the corner. The system intervenes to counter any signs of understeer or oversteer. For the driver, this means reduced effort at the steering wheel and even higher lateral acceleration.

The active sport differential is a new type of rear-axle differential. A superposition gear was added to both the left and right sides of the classic differential; it rotates ten percent faster than the wheel’s drive shaft.

Both components can be connected through a multidisk clutch, which runs in an oil bath, and is operated by an electro-hydraulic actuator. In most driving situations, the clutch can divert almost the complete input torque to one wheel in this way.

Controlled by an array of sensors and a high-speed computer, the active sport differential needs less than 100 milliseconds to redirect power. Drivers can adapt their manner of driving, along with characteristics for the load changes, to three performance maps. Unlike competitors’ systems, the Audi sport differential is just as effective when the engine is driving the wheels as it is on the overrun or when the car is coasting freely.

The new Audi S4 and S4 Avant are well-trained athletes. Their five-link front axle and the self-tracking trapezoidal-link rear axle are of a highly sophisticated design; both axles are made almost entirely of aluminum and are therefore very lightweight. The low-mounted steering gear transmits the steering forces to the wheels without any lag time and gives the driver a precise and sensitive road feel.

The spontaneity of Audi’s new midsize athletes is fascinating, and they possess the precise reactions of a thoroughbred sports car. In these transmissions, the differential is positioned in front of the clutch, which made it possible to move the engine 154 mm (6.06 in) forwards compared with the predecessor model. This unusual layout perfectly evens out the axle loads, and also affords the long wheelbase of 2,811 mm (9.22 ft) exceptional stability.

The chassis of both new S models received stiffer axle bearings, and the sporty tuning with stiff shock absorbers puts the chassis 20 mm (0.79 in) closer to the road. Huge high-performance and fade-resistant brakes sit behind the 18-inch and optional 19-inch cast aluminum wheels. The black-painted brake calipers – at the front with the S4 logo – grip the ventilated disks with newly developed brake pads.

Audi drive select: The driving dynamics system

The Audi drive select driving dynamics system is a further high-end technology featured on the new S4 and S4 Avant. It accesses the throttle response characteristics, the shift points for the seven-speed S tronic and supports the speed-dependent servotronic steering. With the press of a button, the driver can decide whether these systems should operate in “comfort,” “auto” or “dynamic” mode. If the vehicle is equipped with the MMI operating system, a fourth mode is available which the driver can program according to his own personal tastes and preferences.

Audi drive select can only be ordered in combination with one or more of three additional technologies – the sport differential, adaptive control for the shock absorbers, or dynamic steering, which is an additional high-tech solution. Its zero-play superposition gear, which is driven by an electric motor, varies the ratio by almost 100 percent depending on the speed being driven. In terms of driver safety, the dynamic steering assists the ESP stabilization program by using steering intervention to keep the new S4 and S4 Avant on track when cornering at the handling limits. In many instances, the system renders ESP intervention superfluous.

For the adaptive damper control system, hydraulic gas-pressurized shock absorbers are used which operate by means of additional, electrically actuated valves. They control the flow of hydraulic liquid, thus regulating the shock-absorbing characteristics. A high-performance control unit analyzes the signals it receives from 14 sensors, and calculates the damping power for each individual wheel 1,000 times per second.

An athletic look: The design

Both the Audi S4 and the S4 Avant look athletic and muscular on the road. Some of the most striking modifications to the exterior design are the special aprons, the aluminum-look exterior mirrors, the 18-inch S-design light-alloy wheels, the side rocker panels, the restrained spoiler at the rear and the quadruple exhaust system. The xenon plus headlights with daytime running lights and the rear lights are further distinctive touches.

The interior also underscores the sporty expertise that is the hallmark of both new S models. The sports seats have electric lumbar supports and pull-out thigh supports, and the instrument panel features gray dials with white needles. They also bear the S4 emblems, as do the multifunction sport steering wheel and the key. The interior is in black, with brushed aluminum inlays. Carbon and birch wood inlays are also available, as are stainless steel mesh inlays.

Optional assistance systems provide the driver with even greater control on the road. The adaptive cruise control (ACC) regulates the distance to the vehicle in front, and braking guard issues warnings regarding possible rear-end collisions. The Audi side assist makes changing lanes safer; the Audi parking system advanced makes backing into a parking space easier.

With regard to multimedia, Audi offers an attractive technology package. The communications and entertainment technologies portfolio includes the competition-beating MMI operating system, various types of radio and sound systems all the way up to the high-end solution from Bang & Olufsen, two navigation systems, an iPod interface, and a highly convenient Bluetooth car phone.

Luxurious features such as the three-zone deluxe automatic air conditioning and the dynamic cornering light system known as adaptive light round out the optional equipment.

Audi will begin delivery of its new S models in March 2009.

Audi Launches Diesel Offensive in the US

2008-09-08T13:26:00Z

The TDI is the world’s most successful efficiency technology. Now the latest Audi TDI is making its way to the US: Audi is introducing the world’s cleanest diesel to the streets of America inside the Audi Q7 3.0 TDI with ultra low emission system. Once there, and prior to its market launch, it will prove its supremacy when it comes to driving fun and fuel efficiency in an endurance test – the Audi Mileage Marathon.

The Mileage Marathon covers more than 4,800 miles – that’s over 7,700 kilometers – running from New York to Los Angeles through major cities and passing countless natural wonders. From October 5-20, 184 drivers from all over the world will do more than just get to know a lot of fascinating roads during a total of 13 daily stages – they’ll also experience the confident sportiness and extraordinary efficiency of the TDI models from Audi.

The big real-world driving tour will be driven with 23 cars from four different model lines, all examples of Audi’s characteristic combination of superior mobility and unbeatable efficiency. Along with the Audi Q7 3.0 TDI, the brand new Audi Q5 3.0 TDI will make its debut on the wide roads of the North American continent. The Audi A4, the sportiest sedan in its class, will also make its appearance with the superb 3.0 TDI engine.

The Audi A3 Sportback 2.0 TDI – equipped with the innovative and particularly efficient S tronic transmission – will add yet another highlight to the Mileage Marathon’s efficiency statistics.

Efficiency is key over the long haul
The route of the Audi Mileage Marathon leads across the American continent from New York to Los Angeles, passing major cities like Chicago, Dallas and Las Vegas during the 13 daily stages, as well as natural wonders including the Rocky Mountains, Death Valley and the Grand Canyon. The entire route totals more than 4,800 miles – over 7,700 kilometers – with a realistic mix of city driving and rural driving on highways and country roads. In this environment and under conditions that come close to everyday driving, the TDI will be able to clearly show off its superiority over every other efficiency technology.

Debut for the TDI with ultra low emission system
In the Audi Mileage Marathon, the TDI with ultra low emission system will be making its debut in a tough endurance test several months before the planned market launch in the US and in Europe in 2009. This exhaust emission control system reduces nitrogen oxides by up to 90 percent, making it compliant with California’s LEV II BIN 5 – the world’s most stringent emission standard. It also already exceeds the requirements of the Euro 6 standards that are targeted for 2014. The Audi Mileage Marathon will show that this doesn’t reduce the engine’s dynamism and outstanding fuel efficiency.

With the latest generation of TDI, Audi once again confirms its pioneering role in the world’s most successful technology for fuel efficiency: when Audi started series production of the first TDI, the engine was clearly a major technical advancement. The TDI quickly became a synonym for superior propulsive power and top efficiency, and set the trend for the entire automotive industry. There is still no propulsion system that can beat the TDI when it comes to high performance and actual fuel consumption.

Major potential to reduce worldwide consumption levels
Since it features the lowest emissions, the TDI with ultra low emission system can be employed worldwide, even in California and all other US states that currently have the most stringent emission standards. Compared with the fleet average of the gasoline engines typically found in the US, the TDI achieves a fuel-efficiency advantage of up to 40 percent. This means that today’s diesel technology that is designed for tomorrow can make a greater contribution than any other type of engine to reducing the consumption of fossil fuels.

Part of an integrated efficiency strategy
Perfecting the TDI is just one part of Audi’s integrated technology strategy to further reduce CO2 and the emission of pollutants in all models. Audi meanwhile relies on the outstanding potential of its state-of-the-art combustion engines and on the components of its modular efficiency system: with direct injection and turbocharging, the TFSI gasoline engines and TDI diesel engines already provide convincing performance with comparatively low consumption, while their innovative technologies form a solid basis for further significant reductions of consumption in coming years.

AUDI AG sold a total of 964,151 cars in 2007 and thus achieved its twelfth consecutive record year. With revenue of €33,617 million and profit before tax of €2,915 million, the company attained its best figures ever. Audi produces vehicles in Ingolstadt and Neckarsulm (Germany), Györ (Hungary), Changchun (China) and Brussels (Belgium). At the end of 2007, production of the Audi A6 started in Aurangabad, India. The company is active in more than 100 markets worldwide. AUDI AG’s wholly owned subsidiaries include Lamborghini S.p.A. in Sant’Agata Bolognese, Italy, and quattro GmbH in Neckarsulm. Audi currently employs around 57,000 people worldwide, including 45,000 in Germany. The brand with the four rings invests more than € 2 billion each year in order to sustain the company’s technological lead embodied in its “Vorsprung durch Technik” slogan. Audi plans to significantly increase the number of models in its portfolio by 2015 to 40.

Audi Develops Worlds Most Powerful Diesel SUV

2008-09-08T13:14:00Z

For two decades Audi has driven forward the advancement of diesel technology – from the very top. Now the brand with the four rings is presenting another world first: the first V12 TDI in a passenger vehicle. The diesel, which generates an output of 368 kW (500 hp) and 1,000 Nm of torque (737.56 lb-ft) from a capacity of six liters, gives the new Audi Q7 V12 TDI quattro the performance of a sports car. It catapults from zero to 100 km/h (62.14 mph) in only 5.5 seconds and has an electronically capped top speed of 250 km/h (155.34 mph). The V12 diesel is opening up entirely new horizons in the diesel sector. The big-performance SUV from Audi completes all intermediate sprints with fascinating ease; in every driving situation it boasts superior reserves of power. The engine captivates its drivers not only with its sheer inexhaustible power but also with its highly cultivated manner of operation – the subtle engine sound takes on a voluminous, strong note when the throttle is open. In terms of fuel consumption the six-liter TDI, which features a completely redeveloped common rail injection system, requires an average of only 11.3 liters/100 km (20.82 US mpg), substantially less than the gasoline units produced by the competition. No competitor is able to match this achievement.

Engine
The new twelve-cylinder TDI, produced at the Györ plant in Hungary, is a member of the current family of V diesel engines from Audi, which up to now was restricted to 6 and 8-cylinder units. As with other inline engines, it has a spacing of 90 millimeters (3.54 inches) between cylinder centers. Yet its included angle is 60 degrees, not 90 – the reason is that on this layout of V12, no free inertial forces or mass moments of inertia can then occur. The results are refined in every respect.

The 83.0-millimeter bore (3.27 inches) and 91.4-millimeter stroke (3.60 inches) of the twelve-cylinder are the same as the 3.0 TDI, producing a total displacement of 5,934 cc. The two cylinder banks are positioned opposite one another with an offset of 17 millimeters (0.67 inch). Measuring 684 millimeters (26.93 inches) in length the powerful engine is extremely compact, only 166 millimeters (6.54 inches) longer than the V8 TDI. This dimension was the key prerequisite for integrating the V12 into the Audi Q7.

The V12 TDI crankcase is made from cast iron with vermicular graphite – a high-tech material referred to as GJV-450 that is already used on the V6 and V8 TDI engines. GJV-450, made by a patented casting process, is about 40 percent more rigid and 100 percent more fatigue-resistant than gray cast iron. This enabled the developers to make its walls thinner, cutting its weight by around 15 percent compared with conventional gray cast iron. The crankshaft forged from chrome-molybdenum alloy steel is mounted with the aid of an extremely rigid main bearing bridge made of nodular cast iron. The forged connecting rods are cracked and the pistons are made of aluminum.

The two cylinder heads are each made from three main elements. The base section is made from a high-strength, lightweight aluminum alloy, through which the coolant flows and where the intake and exhaust ports are incorporated. Above this are an oil-bearing upper section and a reinforcing ladder-type frame supporting the two camshafts. The valves are actuated by low-friction roller cam followers. The compression ratio is 16.0:1.

As usual on the Audi V engines, the no-maintenance chain drive is mounted on the reverse of the engine, where it occupies little space. However, it has a new layout: the camshaft’s sprocket engages in an intermediate gear via which two simplex chains drive the camshafts. Two additional chains drive the oil pump and the high-pressure pumps for the common rail injection system – an important innovation for the V12 TDI.

MTM Tackle The Audi R8

2008-09-05T12:40:00Z

It's been a busy few weeks for the folks at MTM. Hot on the heels of the recent MTM upgrade package for the Audi TTS, they've gone and done it again, this time turning their attention to the 4.2-liter V8 powered Audi R8 - Opting this time to fit a screw-type supercharger to the V8 as well as ECU and handling upgrades. As part of the specification the usual parts are also upgraded, as we see with the signature MTM bi-moto lightweight alloy wheels, this time pumped up to 20 inches, to accomodate those english county sized 380mm brake disks (rotors).

Performance is increased by a mere 130BHP over its stock counterpart and acceleration to 60MPH is also lowered as a result. No doubt the 100 lb/ft torque increase has a part to play, also.

Engine - V8 compressor with twin-srew belt driven supercharger
Capacity - 4163 cc
Drilling x Stroke - 84,5 x 92,8 mm
Densification (Compression) - 12.5 : 1
Gearbox - 6-speed manual gearbox
Power - 560 PS (412 kW) (552 BHP)
Torque - 580 Nm (427 lb/ft)
Max Speed - limited 187MPH (195 MPH with limiter removed)
Acceleration 0 -100/200 km/h: 3.9 sec./12.5sec

And, just in case you're wondering what all that gumph above sounds like....

ABT Sportsline Audi RS6

2008-08-21T19:49:00Z

How do you get the superlative of the word "car"? The answer is easy and still impressing: car - fast car - ABT RS6, as ABT Sportsline has set a unique benchmark in engineering: thanks to ABT Power the V10 TFSI delivers 700hp (515kW) - and that makes the RS6 a real super sportscar in an elegant but very useful clothing. For comparison: the serial RS6 achieves 580hp (426kW). The "station racecar" displays its maximum torque of enormous 800Nm (series: 650Nm) between 2400 and 6100 rpm. What does that mean? The ABT RS6 is at any time and in any situation a superior vehicle with an engine that belongs to the extremely fast ones thanks to its top speed of 310 km/h. Of course the currently most dynamic one of ABT Sportsline's car creations is easy to steer through daily traffic. The driver should, however, contain his leadfoot: beware when the ABT RS6 is unleased...

Suspension springs and lowering provide for optimal road holding; Christian Abt has checked the tuning with his legendary "buttometer" and has had a whole lot of fun: "The RS6 is breathtakingly fast; it shows how perfectly knowledge in the field of engine technology and racing experience blend together." Also when it comes to the body kit, both parts of the company - motorsports and car tuning - work closely together. So the rear wing is not only a beautiful add-on part for the super station wagon, it also reduces the lift of the bodywork. Striking style elements are the front spoiler, a highly dynamic "carbon-blade" and the 4-pipe-rear muffler typical for ABT in matt black finish. The dynamic BR wheel rim in extravagant 20 inches suits the Allgäu super station wagon particularly well. This makes the RS6 look very sporty and unique; still, the agile 700hp are not too apparent: the ABT RS6 is surrounded by an air of understatement, as its spectacular riding qualities only show on the road. The RS6 is a benchmark set by ABT Sportsline.

Engine Data and Facts
Engine: V10 TFSI, 4991cc engine capacity
Performance upgrade: ABT Power
Performance: 700hp/515kW (series: 580hp/426kW)
Rated torque: 800Nm between 2400 and 6100 rpm (series: 650Nm between 1500 and 6250 rpm)
Top speed: 310km/h (series: 250km/h, limited)

Audis RS6 gets a power hike from B&B

2008-08-20T13:16:00Z

Seemingly as if the 5.0-liter FSI twin turbo V10 powered New Audi RS6 wasn't in need of more power, Audi Tuning guru's at B&B Automobiltechnik have raised the bar with their latest upgrade for the range topping Audi Saloon and Estate. In standard form the 5.0 litre engine, derived from the Lamborghini Gallardo, pumps out a not to be sniffed at 580BHP which by any standards makes the Audi pretty quick. So when B&B fettled about and wound up hitting 715BHP we just had to find out what they've done to wring those extra horses out of the engine.

Rather than adopting the usual turbo upgrade package, which other tuners usually turn to for raising the power stakes, B&B instead opeted for a high flowing racing exhaust and uprated air intake, coupled with upgraded intercooling and the all import ECU mapping. All of which culminates in a 135BHP increase over stock figures. Paper based figures are great, but what we want to know is how it's like out on the open road. As usual B&B also released some acceleration figures, showing their upgrade can now propell the new Audi from 0-100km/h in a super car biting 3.6 seconds. Making it just under one second quicker than its standard counterpart.

The 2009 Audi RS6 Saloon

2008-08-12T11:31:00Z

426 kW (580 hp) and 650 Nm (479.42 lb-ft) of torque – with its twin-turbo V10 and quattro permanent all-wheel drive, the Audi RS 6 is a car without equal. Following on the heels of the RS 6 Avant, Audi now presents the sedan. It drives like a supercar thanks to its superior performance and thrilling dynamics, yet offers all of the everyday utility of a large business sedan.

The engine of the new Audi RS 6 is a high-tech work of art. The 4,991 cc V10 bundles a number of Audi’s race-winning technologies – FSI direct fuel injection, dry-sump lubrication and two turbochargers. With up to 1.6 bar of boost pressure, these provide smooth, powerful thrust and an incomparable power band: The peak torque of 650 Nm (479.42 lb-ft) is available from 1,500 to 6,250 rpm and thus nearly over the entire rev range. Peak power of 426 kW (580 hp) is generated between 6,250 rpm and the maximum figure of 6,700 rpm.

With a power-to-weight ratio of 3.4 kilograms per hp, the Audi RS 6 performs like a supercar. It catapults to 100 km/h (62.14 mph) in 4.5 seconds on its way to an electronically-limited top speed of 250 km/h (155.34 mph), which can be optionally raised to 280 km/h (173.98 mph). The V10 responds immediately and spontaneously to the throttle, and is very smooth while accelerating with a powerful roar.

The engine’s power flows through the six-speed tiptronic, one of a new, dynamic generation of Audi automatic transmissions. Its reaction time has been reduced to one tenth of a second, shift time has been halved compared to units used in other models and transmission ratios are short. The driver can also manually change gears either using the shift lever or the paddles on the steering wheel. The tiptronic transmission transfers the power to an extremely sporty, rear-weighted quattro drive train.

Precision high-tech suspension

The technology bundled into the suspension of the Audi RS 6 guarantees an amazing performance experience. The front axle features four lightweight aluminum control arms per wheel, whose elastokinematics have been designed for particularly sporty performance. The characteristics of the speed-dependent servotronic power steering were retuned and the steering gear ratio is a direct 12.5:1. The rear suspension kinematics have also been modified.

The development engineers have also deployed an exclusive damping technology: Dynamic Ride Control DRC reduces pitch and roll using purely mechanical means. Hydraulic lines and valves connect diagonally opposed pairs of shock absorbers. When cornering, the flow of fluid to the damper of the compressing outside front wheel increases, providing firmer support and reducing roll. When combined with the sports suspension plus, DRC offers a choice of three selectable damper settings – sport, dynamic and comfort – which can be activated via the MMI.

The electronic stabilization system ESP offers maximum driving fun with uncompromised safety. Its relatively high activation threshold encourages a dynamic driving style. It offers a Sport mode and can also be deactivated entirely.

The new Audi RS 6 rolls on 19-inch alloy wheels shod with 255/40 tires. Up front, six-piston fixed aluminum calipers – painted black and decorated with RS badges – clamp down on 390 millimeter brake disks. The rear brake disks measure 365 millimeters in diameter. The rear axle features single-piston floating brake calipers. The floating steel disks feature large cooling ducts and axial perforations for enhanced performance and less weight.

9.5J x 20-inch wheels are offered as an option. These allow the use of a ceramic brake system. The 420 (front) and 356 (rear) millimeter disks weigh a total of 12.2 kilograms (26.90 lb) less than the steel disks. The calipers – up front with eight pistons – are painted anthracite and labeled “Audi ceramic.”

The body of the 4.93 meter (16.17 ft) RS 6 also sports a number of distinctive features that immediately identify it as a dynamic, top-of-the-line model. These include the single-frame grill, the air intakes, the headlights featuring xenon plus, adaptive light and RS 6-specific LED daytime running lights, the flared fenders and deep side skirts, the rear diffuser, the spoiler integrated into the trunk lid and the two large oval exhaust pipes.

The finest of materials and uncompromised quality

Like all Audi RS models developed and built by quattro GmbH in cooperation with AUDI AG, the RS 6 is the embodiment of power, elegance, exclusivity and perfection. The interior is adorned with the finest of materials such as carbon fiber, aluminum, piano lacquer, leather and Alcantara in tried-and-tested Audi quality.

The deeply sculpted sports seats provide optimal support and firm hold. The power-adjustable seats are upholstered in Silk Nappa leather, with leather/Alcantara and Valcona leather available as options. Bucket seats with an even more sporty emphasis are also offered for both driver and front passenger. Standard equipment includes the dual-zone deluxe automatic air conditioning plus, a parking assistant at front and rear, an RS leather multifunction sports steering wheel with flat-bottomed rim and a Bose surround sound system. A boost pressure indicator for the two turbochargers in the driver information system rounds out the instrumentation.

The options are also pure hi-tech: Audi lane assist helps to keep the car in its lane, adaptive cruise control maintains a constant distance to the car ahead and Audi side assist helps the driver change lane safely. The Audi Bluetooth car phone integrates perfectly with the driver’s cell phone to make even using the phone a luxurious experience. It is integrated into the standard MMI operating system, a new generation of which is making its debut in the Audi RS 6.

The Audi RS 6 will be launched on the market in mid-October. The starting price in Germany including VAT is 105,550 euros.

Audi unveils the new 2009 A6 Saloon and Avant

2008-08-12T11:11:00Z

A winner always builds on his strengths: That’s why Audi has again upgraded its luxury class A6 model. Efficient engines have been added to the drive-train lineup, with innovative technologies cutting fuel consumption by about 15 percent across the whole model range. An improved suspension and new high-tech assistance system give the driver even greater control over the car. And the new-generation MMI control system is out-performing itself. The revamped A6 will be launched in the German market in late summer.

It’s the sportiest and most popular business sedan on the market. The Audi A6 is leading the Premium C pack – both in Europe and around the world. In 2007, Audi sold about 234,000 units, giving the A6 a 37 percent market share among its core competitors. Most of the A6’s sold were equipped with six- or eight-cylinder engines, permanent 4x4 quattro and a luxury assortment of optional equipment – all evidence of the high regard Audi technologies is enjoying worldwide.

Its design is emphasized by a range of bold new accents, perfectly articulating the A6’s strong personality. The single-frame grill, bumpers, air vents and fog lights have all gotten a facelift.

The optionally-available xenon plus, LED daytime running lights have been redesigned as horizontal strips with 6 LEDs each. Other options include Audi adaptive light, a dynamic cornering light system, and the high-beam assistant that automatically switches between the high and low beam.

An aluminum-colored molding traversing the sides emphasizes the A6’s dynamic contour. At 4.93 meters (16.17 ft) long, 1.86 meters (6.10 ft) wide, and 1.46 meters (4.79 ft) high, little has changed in the sedan’s generous proportions. The gentle lip on the trunk, integrated chrome strip on the bumper, broad diffuser and straight exhaust pipes are part and partial of the revamped rear end. The bipartite rear lights with LED technology have also gotten a new look: narrow and wide, they taper inward on the sedan. And there are 13 exterior colors to choose from, including five new ones.

The A6’s spacious interior with its clean and elegant contours and perfect craftsmanship is characteristic of this luxury brand. The rear seats are extremely comfortable and the L-shaped headrests improve the driver’s rear view visibility. As an option, the back seats can be fitted with a comfortable 2-seater bench. A package of elaborate features makes sure the noise level is cut by almost half, particularly within critical frequency ranges.

The instrument panel uses new higher-resolution graphics; and a new frame better accentuates the display (color in the optional MMI navigation system). Tastefully-appointed chrome trim, even on the spokes of the steering wheel, call attention to its overall elegance and inlays are available in either aluminum look or fine woods.

As is expected of an Audi, the interior designers have made sure all the colors and materials match. Standard seats can be optionally upholstered with a new material; the sport seats are available in Valcona leather. Soft armrests on the doors increase comfort, while the integrated headrest system reduces the danger of whiplash.

Audi is now offering an S-line sports package for the most dynamic of drivers. The package includes enhanced performance features like 18-inch wheels and sports suspension that lowers the ride height by 30 millimeters (1.18 in). Its sporty seats, decorative inlays and upholstery give the black-trimmed interior a feeling of even more exclusivity and the S-line exterior package provides more drama. Features from this Audi exclusive program are tailor-made to fit the A6’s luxury-seeking mavericks.

One of the major strengths of the A6 lies in its broad selection of engines: six gas and four diesels use direct fuel injection and cutting-edge FSI, TFSI and TDI technologies in a choice of four, six or eight cylinders. Whether stick shift, convenient tiptronic or high-efficiency multitronic, the energy literally flows to the front wheels, or all four wheels for that matter. Its engines are both powerful and efficient. New measures have been introduced to optimize engines and minimize fuel consumption without sacrificing one ounce of driving pleasure. Fuel consumption over the whole A6 family has been lowered by about 15 percent.

The smallest gas engine is the 2.0 TFSI, a 125 kW (170 hp) turbocharged four-cylinder unit. On the other end of the spectrum is the 4.2 FSI, a 257 kW (350 hp) V8 engine. Audi V6 models can be equipped with one of its two new 2.8 liter FSI engines; the 140 kW (190 hp) or the 162 kW (220 hp). Both engines feature the innovative Audi Valvelift System (AVS), which manages the inlet valve timing so that there is more torque and less fuel consumption. Regardless of which 2.8 FSI engine the A6 sedan is fitted, average fuel consumption is only 8.2 liters per 100 kilometers (28.68 US mpg) for the 190 hp, 6-speed manual shift or 8.4 liters per 100 kilometers (28.00 US mpg) for the 220 hp multitronic CVT.

With its 3-liter displacement and 213 kW (290 hp) power output, the V6 is a particularly exciting newcomer. Audi has designed the perfect package for each one of its engine. That’s why the 3.0 TFSI is fitted with a supercharger. From now on “T” doesn’t just stand for turbocharged – it stands for supercharged. Supercharger technology does not mean increased consumption – but the short intake paths do mean instantaneous response. And it’s got full power build-up even at low engine speeds: from 2500 1/min to 4850 1/min, the torque curve is broad and flat at 420 Nm (309.78 lb-ft).

The 3.0 TFSI comes with tiptronic and quattro drive train. The A6 sedan accelerates from 0 to 100 km/h (62.14 mph) in 5.9 seconds and keeps on going as it presses to its electronically-regulated maximum speed of 250 km/h (155.34 mph). This is the kind of performance that only an eight-cylinder engine would have been able to deliver a few years ago. At 9.5 liters per 100 kilometers (24.76 US mpg) on the EU cycle, the supercharged V6 is amazingly economical. The 3.0 TFSI’s combination of dynamic performance and low consumption is one more example of Audi’s successful efficiency strategy.

The A6 TDI engines give further evidence of just how closely Audi has been able to align sporty performance and efficiency. Fuel is delivered by the extremely sophisticated and quiet system of common rails with rapid-action piezo injectors and an injection pressure of 1800 bar (26,106.79 psi). The two V6 TDI engines (2.7 TDI with 140 kW (190 hp) and 3.0 TDI with 176 kW (240 hp) have peak torques of 380 Nm (280.27 lb-ft) and 450 Nm (331.90 lb-ft), respectively.

At the lower end of the diesel program is the four-cylinder 2.0 TDI engine, which is available in two versions: the 125 kW (170 hp), expected in fall 2008, and the 100 kW (136 hp). The basic version is an especially efficient e-model known as the 2.0 TDIe, which uses a six-speed manual shift or automatic multitronic transmission to deliver 320 Nm (236.02 lb-ft) of torque to the front wheels. With multitronic it sprints from 0 to 100 km/h (62.14 mph) in 9.9 seconds, and continues on to a top speed of 204 km/h (126.76 mph). Yet its average fuel consumption with a manual shift gearbox is only 5.3 liters per 100 km (44.38 US mpg), equivalent to CO2 emissions of app. 139 grams per kilometer (224 grams per mile).

The key to achieving such exemplary values is the strategic deployment of innovative technologies. The power steering pump operates on demand; the alternator regenerates electrical energy when coasting thereby reducing load off the engine. By lowering the ride height by 20 millimeters (0.79 in) and other aerodynamic fine-tuning, the drag coefficient has been reduced to cD = 0.28.

The transmission can be used longer in the upper two gears. Any manual-shift A6 with Driver Information System, even the 2.0 TDIe, can opt to have the shift indicator displayed in the instrument panel. The icon lets the driver know which gear is most economical under actual circumstances.

Audi quattro four-wheel drive is available on all engines with 140 kW (190 hp) or above and is standard equipment on high-end aggregates. The manual shift, 140 kW (190 hp) 2.8 FSI notwithstanding, this is the very latest generation quattro with the newly emphasized rear-end design. It gives the A6 tremendous driving characteristics, remarkable grip and superior safety. Under normal conditions, the torque split is 40 percent to the front wheels and 60 percent to the rear. The mechanically-operated Torsen differential immediately diverts most of the power to the axle, providing better traction whenever the need arises – in extreme cases, up to 65 percent to the front or 85 percent to the rear.

In fine-tuning the A6, two key objectives were identified – increasing its comfort while retaining its sporty character. With new large-diameter, front-axle shock absorbers operating within an optimized valve system, Audi engineers were able to achieve both goals. Every other aspect of the suspension set-up has been improved, including the automotive spring response.

The A6 can be equipped with factory-fitted adaptive air suspension so that the driver can vary his response and the characteristics of the adaptive shock absorbers into three styles. High-powered engines come equipped with larger 17-inch wheel brakes. Audi can also be fitted with a tire pressure monitoring system, which is entirely wear-free and maintenance-free. The customer can opt for run-flat tires, which limit the car to 50 kilometers (31 miles) should there be a drop in air pressure.

Audi has integrated several new high-tech assistance systems. The new Audi side assist kicks in to help drivers when changing lanes at speeds over 30 km/h (18.64 mph), ensuring a stress-free and superior drive. Using radar sensors, Audi Side Assist is able to detect other cars up to 50 meters (164.04 ft) away: a signal on the outside mirror lights up should changing lanes pose a threat. Audi lane assist helps keep drivers in their own lane, radar-assisted adaptive cruise control keeps a steady distance to the vehicle ahead, and Audi parking system advanced has a rearview camera.

Since its debut in 2002, the Audi Multi Media Interface system (MMI) has been setting the standard for perfectly controlling any number of functions. The A6 comes equipped with the latest MMI generation, including the top-of-the-line MMI Navigation plus. Its basic construction has not changed. The central control knob can still be found on the middle console between the front seats and the operation is still carried out using large buttons. The new joystick capping the control knob means the MMI Navigation plus can be operated even more intuitively.

MMI Navigation plus is an ultimate solution, pioneering in an entirely new system generation with high-tech portfolio and ground-breaking standards. Special features include a CD/DVD/Navigation combination drive with a 40 GB hard drive capacity which can be used to store MP3s and up to 5000 addresses.

With its 7-inch, high-resolution screen, the monitor on this ultimate navigation system is truly innovative. The image is rich in contrast and incredibly sharp even under difficult lighting conditions. It also has an optional TV tuner that receives digital programs (DVB-T) in perfect quality.

The new navigation system has another innovation. A new bird's eye picture mode shows landscapes in topographical relief – in full detail, complete with three-dimensional images of landmark buildings. The monitor has a new operating principle: when adjusting specific functions like air conditioning or seat heating, a pop-up window appears at the right rather than taking over the whole screen.

Most of the new features found in the A6 sedan and Avant are also present in two other models: the versatile A6 allroad quattro and the dynamic S6. The A6 allroad quattro can be powered either by the new 213 kW (290 hp) 3.0 TFSI engine or one of the two powerful V6 TDI diesels. The V10 on the S6 has 320 kW (435 hp). Changes made to the sports model are limited to interior and exterior optical details.

The upgraded Audi A6 will be available in German dealer showrooms as of mid-October 2008. Starting at 34,200 Euros for the A6 2.0 TFSI sedan, Audi’s initial list prices have remained virtually unchanged, despite all the extensive innovations.
