2013 Audi S6

The 2013 Audi S6 is fully redesigned, with a more full-efficient engine, a new chassis and new driving-technology features. The new engine is a twin-turbo 4.0-liter V8 engine that produces 420 horsepower and 406 lb-ft of torque and features stop-start and cylinder-deactivation technologies for improved fuel efficiency. The chassis is redesigned, constructed of an ultra-lightweight aluminum hybrid and placing the engine farther rearward for better handling. The S6 now offers driving-technology features such as adaptive air suspension, electromechanical steering and electronic stability control. New interior and exterior design cues differentiate the S6 from the A6, such as an “S” single-frame grille and front bumper, “S” rear diffuser and rear bumper, and a trunklid spoiler.
