2012 Audi S7 Sportback: full details, specs and photos

The Audi S7 Sportback is powered by the new 4.0 TFSI, which is the engine used on the S6 and S6 Avant. It delivers 309 kW (420 hp) and 550 Nm (405.66 lb-ft) of torque on the S7 Sportback. The five-door coupe is powered by the twin-turbo V8, enabling it to accelerate from a standstill to 100 km/h (62.14 mph) in 4.9 seconds and to reach a limited top speed of 250 km/h (155.34 mph). With a fuel consumption rating of 9.7 liters per 100 km (24.25 US mpg), this cultivated eight-cylinder uses Audi's "cylinder on demand" technology under part load. This impressive efficiency is mostly due to its lightweight body of hybrid aluminum construction. Its weight is about 15% lower than one with an all-steel body.

One of its lightweight parts is the long rear hatch that opens and closes electrically as standard. Under it is a luggage compartment with a volume of 535 liters (18.89 cu ft). When the rear seat backs are folded down, the space increases to 1,390 liters (49.09 cu ft). The Audi S7 Sportback’s power transmission comes from the dynamic seven-speed S tronic and the quattro permanent all-wheel drive system that has a self-locking center differential and torque vectoring. Audi’s optional sport differential distributes the power in different proportions between the rear wheels. The S7 Sportback is available as standard with the adaptive air suspension sport and the Audi drive select dynamics system.

At the back of the 19-inch wheels, we see huge, internally ventilated disc brakes front and rear. Their matt black calipers feature S7 logos up front. Offered as an option are carbon fiber-ceramic discs. The other chassis options include 19- and 20-inch wheels and dynamic steering, which varies its ratio as a function of speed. The Audi S7 Sportback has a seamless design. Ideal proportions are the result of its long engine hood, long wheelbase and short overhangs. The five-door model has the coupe’s character with the addition of the low, dynamically tensioned roof line. To enhance stability, a rear spoiler extends from the rear hatch at highway speeds. Even the interior shows off just how sporty the S7 Sportback is, from the S badges, the red ring on the start-stop button, the S7 logo in the illuminated door sill trims, the aluminum strip on the S tronic selector lever and the aluminum shift paddles. Stainless steel is used for the footrest and the pedals. The soft keys of the MMI operating system come with an aluminum-look finish.[via : 4wheelsnews]
