The luxury coupe uses the same engine as the new 2012 S6 and S6 Avant, the new 4.0 TFSI with 420hp and 550Nm of maximum torque. The twin-turbo V8 accelerates the five-door coupe from 0 to 100km/h in 4.9 seconds, and top speed is limited to 250km/h. The eight-cylinder uses Audi’s “cylinder on demand” technology under part load for a lower fuel consumption.
Much of the new efficiency can be attributed to the lightweight body. A hybrid aluminum construction, it weighs roughly 15 percent less than a comparable all-steel body. Lightweight components include the long rear hatch that opens and closes electrically as standard. Beneath it is a luggage compartment with a volume of 535 liters, which increases to 1,390 liters with the rear seat backs folded down.
Power transmission in the Audi S7 Sportback is provided by the seven-speed S tronic and the quattro permanent all-wheel drive system with a self-locking center differential and torque vectoring. The optional sport differential from Audi distributes the power in variable proportions between the rear wheels. The S7 Sportback comes standard with the adaptive air suspension sport and the Audi drive select dynamics system.
Mounted behind the 19 inch wheels are large, internally ventilated disc brakes front and rear. Their matt black calipers sport S7 logos up front. Carbon fiber-ceramic discs are available as an option. Other chassis options include 19 and 20 inch wheels and dynamic steering.
S7 Sportback details can be found at the single-frame grille, the front bumper, the side mirrors, the sills, the rear bumper, the diffuser and the tailpipes.
Audi equips the S7 Sportback with height-adjustable S sport seats with power lumbar supports as standard. Comfort seats and regular seats are available as options. The backrests of the S sport seats are embossed with S logos.
Delivery of the S7 Sportback is scheduled to begin in Spring 2012. Pricing is not yet available at this stage.
