Audi RS6 Sedan to debut at the Paris show in October

According to Auto Motor und Sport, the Audi RS6 Sedan will debut this fall, at the Paris Motor Show, in October. A prototype of the car was caught by German photographers and we can tell that, except the modified tail-lights, the car is pretty much the same with the RS6 Avant. Under the hood, the car will be powered by the same 580 hp V10 twin-turbo FSI direct-injection engine as the Avant (of course, not if MTM ‘messes’ with it).
