The intrepid studs and studettes at German Car Fans (by the way, did you know that "Stuttgart" is derived from the German word for "stud farm"?) got their mitts on some spy photos of Audi's upcoming S6. Look out, M5: word is that RS6 will feature a 5.5L V-10 pumping out 550 ponies and 413 lb ft of grunt. The proletarian S6 will make do with 440hp & 396 lb ft. Piffle.
