The new Audi S6 and the Audi S6 Avant are sports cars for everyday. They are powered by a four-liter, twin-turbo V8 producing 309 kW (420 hp) and delivering 550 Nm (405.66 lb-ft) of torque between 1400 and 5300rpm. The innovative cylinder head concept, with the intake side on the outside and the exhaust side on the inside, provides for short gas paths with minimal flow losses for very spontaneous engine response. The two twin-scroll turbochargers ensure prodigious amounts of torque at low revs.
The 4.0 TFSI accelerates the S6 from 0 to 100 km/h (62.14 mph) in 4.8 seconds and the S6 Avant in 4.9 seconds. Average fuel consumption in the S6 is just 9.7 liters per 100 km (24.25 US mpg). Fuel Consumption in the S6 Avant is 9.8 liters per 100 km (24.00 US mpg). A large part of this efficiency can be attributed to cylinder on demand, a newly developed cylinder management system that deactivates four of the eight cylinders under part load. During these phases, Active Noise Control (ANC) largely eliminates intrusive noise by broadcasting a precise antiphase sound to the cabin through the sound system’s speakers. Independent of this, active engine bearings uses counterpulses to attenuate low-frequency vibrations.
The engine’s power flows through a seven-speed S tronic to the quattro permanent all-wheel drive system, which features a self-locking center differential and torque vectoring. If desired, Audi complements quattro with the optional sport differential, which actively distributes the power between the rear wheels. The two new S models come standard with the adaptive air suspension sport. The tautly tuned air suspension with variable damping lowers the body by 10 millimeters (0.39 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 encompasses the optional sport differential and dynamic steering.
