Both versions of the RS6 are, or have been produced as, a five-door five-seat "Avant", Audi's name for a estate car–station wagon, along with a four-door five-seat saloon–sedan. Furthermore, their internal combustion engines are all front-mounted, are longitudinally oriented, and are not shared with any other vehicle. The transmission is mounted immediately at the rear of the engine in a longitudinal orientation, in the form of a transaxle.
