A 580hp station wagon (or sedan, for that matter) seems like sheer lunacy in its own right, but it appears that the twin-turbo V10 in the Audi RS6 is capable of a great deal more. Following the release of the 702hp MTM-tuned RS6 M, fellow German tuning house B&B Automobiltechnik has an even more potent tuning package, boosting power up to a whopping 715.

So what did the power-hungry gearheads at B&B do to get a 120 horsepower boost out of the Gallardo-derived FSI? They didn't replace the turbos or fit a new supercharger, nor did they bore out the cylinder block for bigger displacement. They simply fitted a new intake, catalyst, exhaust and cooling system, and tinkered with the ECU. B&B are also offering an adjustable suspension and new springs that drop the ride height by 25mm. The result? A claimed 0-60 run in a scant 3.6 seconds. That's well into supercar territory, as many a Porsche and Ferrari driver are bound to discover when baited into an impromptu red-light drag race. Nice work if you can get it.
