The new Audi S6 and the S6 Avant are sports cars for everyday. The 4.0 TFSI, a biturbo V8 producing 331 kW / 450 hp, accelerates the Sedan from 0 to 100 km/h (62.1 mph) in 4.4 seconds. The S6 Avant completes the sprint in 4.6 seconds.
Standard equipment in the new Audi S6 and S6 Avant includes quattro permanent all-wheel drive and the adaptive air suspension, which lowers the body by 20 millimeters (0.8 in). Matt black brake calipers grip the front discs mounted behind the 19-inch wheels.
An eight-speed tiptronic transfers the power from the biturbo V8. The standard quattro drivetrain uses a center differential with a higher locking rate. The RS adaptive air suspension lowers the body by 20 millimeters (0.8 in). Audi offers the taut RS sport suspension with Dynamic Ride Control (DRC) as an option. The large brake discs feature a weight-saving wave design, and the wheels measure 20 inches in diameter. 21‑inch wheels are available as an option.
