2012 Audi S6 Spied

With the new A6 already out the German carmaker thought it could escape but it didn’t because the Motorauthority spies captured the car in testing, including shots of the carbon fiber-clad interior.

The new model is expected to get a punchier version of Audi’s upcoming 4.0-liter V-8 engine, taking the place of the 435-horsepower V-10 engine in the current 2011 S6. Leaked specs for the car peg the new V-8′s output at 434 horsepower, so it won’t be giving up any performance despite lopping off two cylinders.

Probably the S6 will make its debut at September’s Frankfurt Motor Show, this year, but it’s possible it may wait longer.
