The Audi S6 and S6 Avant use the 309 kW (420 hp) version of the new 4.0 TFSI. The twin-turbo V8 provides a constant 550 Nm (405.66 lb-ft) of torque from 1,400 to 5,300 rpm. It accelerates the S6 from 0 to 100 km/h (62.14 mph) in 4.8 seconds and the S6 Avant in 4.9 seconds. With both models, the electronically governed top speed of 250 km/h (155.34 mph) is just a formality.
The 4.0 TFSI brings Audi’s downsizing strategy to the high-performance class. Compared to the engine in the previous model, the free-breathing, 5.2-liter V10, it offers even sportier performance while reducing fuel consumption by as much as 25 percent. Average fuel consumption is just 9.7 liters per 100 km (24.25 US mpg) in the Audi S6 and 9.8 liters (24.0 US mpg) in the Audi S6 Avant.
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 powerful disc brakes, internally ventilated front and rear, have matt black calipers with S6 logos. Audi offers carbon fiber-ceramic discs as an option.
The Audi S6 and S6 Avant come standard with cast aluminum wheels in a unique five parallel-spoke design. The 8.5 J x 19 wheels are shod with 255/40-series tires. Seven different 19- or 20-inch wheels, four of them from quattro GmbH, are available as options. The 20-inch titanium-look wheels with a five-arm rotor design impart a particularly exclusive appearance.
The Audi S6 has a curb weight of just 1,895 kilograms (4,177.76 lb), the S6 Avant 1,950 kilograms (4,299.01 lb). At 4,931 millimeters (16.18 ft), the Audi S6 is 16 millimeters (0.63 in) longer than the A6; with the 4,634-millimeter (15.2 ft) Audi S6 Avant, the difference is 8 millimeters (0.31 in) over the A6 Avant. Their single-frame grille sports aluminum applications and chromed horizontal double bars. Another chrome strip adorns the front bumper. The exterior mirrors feature aluminum-look housings, and the side sills are distinctively shaped.
The Audi S6 sedan has a spoiler on the trunk; the Avant has a roof spoiler. With both models, the diffuser on the rear bumper is platinum gray with an aluminum-look offset edge. The four chrome-tipped tailpipes are elliptical. The S models are available in a choice of eight colors, including the exclusive shades Estoril Blue, crystal effect and Prism Silver, crystal effect. The body is decorated with S6 and V8T badges.
The new Audi S6 and S6 Avant will be rolling into dealer showrooms with a generous list of standard equipment in spring 2012. This includes xenon plus headlights with an all-weather light, LED rear lights, an electromechanical parking brake and the driver information system with color display. All of the high-end options in the model series are also available for the new S models. These include LED headlights, adaptive light, the ambient lighting package, convenience key, head-up display, the parking system plus with 360° camera, power rear hatch, optionally with sensor control, and climate-controlled deluxe seats with massage function.
