The 4.0 TFSI in the revised Audi RS 7 Sportback provides as before 412 kW (560 hp), with a constant 700 Nm (516.3 lb‑ft) of torque at engine speeds between 1,750 and 5,500 rpm. The engine catapults the five‑door coupé from 0 to 100 km/h (62.1 mph) in 3.9 seconds; the optional dynamics packages allow top speeds of 280 and 305 km/h (174.0 and 189.5 mph), respectively. In the ECE cycle however, the resonant V8 bi‑turbo needs only 9.5 liters of fuel per 100 kilometers (24.8 US mpg) with 221 grams CO2 per kilometer (355.7 g/mi). A key factor in this efficiency is the cylinder on demand (COD) system, which can shut down four cylinders during partial load operation.
An eight‑speed tiptronic tuned for sporty performance, with a tall eight gear, directs the power of the eight‑cylinder engine to the quattro permanent all‑wheel drive. On request, Audi will combine quattro all‑wheel drive with the optional sport differential on the rear axle.
The RS adaptive air suspension, together with adaptive damping, standard on the RS 7 Sportback, lowers the body by 20 millimeters (0.8 in); its control is incorporated in the Audi drive select driving dynamics system. Audi offers the tauter RS sport suspension plus with Dynamic Ride Control (DRC) as an alternative. A further option is dynamic steering, with its continuously variable steering ratio.
The revised Audi RS 7 Sportback is fitted with 20‑inch forged lightweight alloy wheels as a standard feature; 21‑inch cast aluminum wheels in three color versions are optionally available. The four internally ventilated brake disks have a weight‑saving wave design; alternatively Audi installs carbon fiber-ceramic disks. Electronic Stabilization Control (ESC) has a Sport mode that can be deactivated altogether if need be.
The Audi RS 7 Sportback can be ordered in Germany from the 3rd quarter 2014. Its base price is €113,300.
