2012 Audi S6 Avant Scooped Undisguised, gets New V8 Shared with Bentley

Audi’s new A6 model series will soon welcome a new member into the family, the sporty S6 that was snagged by our spy photographers in Avant trim during testing in Germany.
The prototype model was completely undisguised, however, there’s a reason for that. With the exception of some model specific details such as the telling quad tail pipes and unique alloy wheel designs, the S6 will remain unchanged from the A6 with the optional S-Line sport package. The latter adds an aero kit with restyled front and rear bumpers, among other parts.
