The Audi S6 and the S6 Avant are sports cars for everyday driving. Their V8 bi-turbo engine - the 4.0 TFSI - delivers 331 kW (450 hp) of power and generates 550 Nm (405.7 lb-ft) of torque, enabling the S6 to sprint in 4.4 seconds (Avant: 4.6 seconds) from 0 to 100 km/h (62.1 mph). The power passes via a seven-speed S tronic to the quattro permanent all-wheel drive system. Audi also complements quattro with the optional sport differential.

Average fuel consumption for the Sedan is only 9.2 liters per 100 kilometers (25.6 US mpg), corresponding to emissions of 214 grams CO per kilometer (344.4 g/mi). Figures for the Avant are 9.4 liters per 100 kilometers (25.0 US mpg) and emissions of 219 grams CO per kilometer (352.4 g/mi). Also contributing to this efficiency is the cylinder on demand (COD) system, which deactivates four cylinders when under partial load. During these phases, Active Noise Cancellation (ANC) largely eliminates intrusive noise by broadcasting a precise antiphase sound to the cabin through the sound system's speakers. At the same time, active engine bearings use counterpulses to attenuate low-frequency vibrations.

Both S models come standard with adaptive air suspension sport. The taut air suspension with variable damping lowers the body by 10 millimeters (0.4 in). The front disc brakes behind the 19-inch wheels have matt black calipers with S6 logos. Audi offers carbon-fiber ceramic discs as an option. The Audi drive select dynamics system also incorporates the optional sport differential and dynamic steering.
