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.
