The Audi S6 is equipped with an all-new twin-turbo 4.0 TFSI® engine that delivers 420 horsepower and an impressive 406 lb-ft of torque from 1,400 to 5,300 rpm. It accelerates from 0 to 60 mph in 4.5 seconds and has an electronically-governed top speed of 155 mph.
The 4.0 TFSI V8 engine brings Audi progressive performance to the mid-sized luxury sedan segment with smaller displacement and higher output. Compared to the previous S6 model, the free-breathing 5.2-liter V10, it offers greater performance while reducing fuel consumption by as much as 25 percent.
The engagement and disengagement of the Audi cylinder on demand is virtually undetectable yet delivers efficiency while maintaining the full power of the twin-turbo V8 available to the driver. When the V8 deactivates four cylinders under part load, active engine mounts counteract vibration while the active noise control (ANC) system minimizes any undesirable sounds from the interior cabin. Four microphones integrated into the headliner monitor noise levels in the cabin and actively cancel unwanted sounds through the main speakers and subwoofer. It is these three systems — Audi cylinder on demand, active engine mounts and ANC — that help define the progressive performance of the Audi S6.
The 4.0T twin-turbo V8 is mated to a seven-speed S tronic® transmission. The grip of the quattro® permanent all-wheel drive system is enhanced further through the sport differential, which delivers superior cornering and agility through turns by directing power to the outside rear wheel during a turn. By utilizing Audi ultra® lightweight technology, the aluminum hybrid construction of the S6 results in lower weight for dynamic handling and greater efficiency. The S6 body panels are aluminum and make up 20 percent of its structure along with its steel frame. Audi drive select allows the driver to adjust throttle response, shift points, boost electromechanical steering and boost adaptive air suspension. Drive select has four settings that include Auto, Dynamic, Comfort and Individual. Air suspension sport with variable damping comes standard, lowering the body by 10 millimeters (0.39 in) for improved handling without compromising comfort. Powerful disc brakes are ventilated and have matte black calipers with the S6 logo prominently displayed on them. The S6 is available with unique 19-inch cast aluminum wheels in a five parallel-spoke design fitted with 255/40-series tires, or unique S7 20-inch parallel- “Star” spoke design wheels with 255/35-series performance tires.
