The Audi S7 is fitted with the new 4.0 liter TFSI® with 420 hp and 406 lb-ft of torque. The
twin-turbo V8 accelerates the five-door coupe from 0 to 60 mph in 4.5 seconds, with a top speed of 155 mph. Great efficiency and nimble performance can be attributed to Audi ultra® lightweight technology. An aluminum-hybrid construction includes lightweight aluminum body panels combined with a steel frame.
A number of additional technologies also contribute to the overall efficiency of the S7, including Audi cylinder on demand. The engagement and disengagement of the cylinder on demand system is virtually undetectable yet delivers great efficiency benefits while still having the full power of the twin-turbo V8 available to the driver. When the V8 deactivates four cylinders under partial load, active engine mounts counteract vibration while the active noise control system (ANC) minimizes any undesirable interior noise. Four microphones integrated into the headliner monitor noise levels in the cabin and actively cancel unwanted sounds via the main speakers and subwoofer. It is these three systems — Audi cylinder on demand, active engine mounts and ANC — that work together to combine efficiency and refinement.
The power of the twin-turbo V8 is delivered via the dynamic seven-speed S tronic® transmission and quattro® permanent all-wheel drive with a self-locking center differential and torque vectoring. The grip of the quattro system is enhanced dynamically through the sport differential, which actively distributes the power between the rear wheels and enables superior cornering and acceleration as the driver exits a turn.
The S7 comes standard with sport air suspension with variable damping and lowers the body by 10 millimeters (0.39 in) for improved handling without compromising comfort. The S7 is fitted with internally-ventilated front and rear disc brakes with matte black calipers and S7 logos. The S7 is available with 19-inch cast aluminum wheels in a five parallel-spoke design fitted with 255/40-series tires or stunning S7-unique 20-inch parallel-spoke “Star” design wheels with 265/35-series performance tires.
The Audi drive select system adjusts several key systems to accommodate various driving conditions and preferences. It modifies throttle response, shift points, steering boost of the electromechanical steering and height of the adaptive air suspension. Drive select has four driver-selectable settings that include Auto, Dynamic, Comfort and Individual.
