The details surrounding the Audi RS6 are out, but that doesn't mean that testing has ended. The RS6 has been sighted donning heavy camo all over the free world, and after the jump we have video of a virtually undisguised RS6 Avant doing a powerslide at a bend of the famed Nürburgring Nordshcleife. The video is almost as quick as the RS6, but if you like screaming engines and squealing tires, it's worth a watch. Heck, part of the reason we're flying all the way over to the Frankfurt Motor Show is to see Audi's fastest ever sedan and wagon.
