All three S series cars are debuting Audi’s new 4.0-liter twin-turbocharged V-8. Audi S7 is no exception. The S7 shares its engine tune with the S6 sedan and Avant, in which the eight makes 420 hp and 406 lb-ft of torque. Both derivatives of the V-8 feature fuel-saving tech with stop-start functionality and a cylinder-deactivation system that will shut down four cylinders under lighter loads. Audi had also installed an active noise-cancellation system that uses four microphones in the headliner to analyze cabin noise and then employs the audio system’s speakers to counteract any plebian four-cylinder sounds.
A seven-speed S tronic dual-clutch automatic will be the only transmission available in the S7, with the standard Quattro all-wheel-drive system feeding power to the ground. The optional torque-vectoring rear differential will further aid performance. Audi estimates the S7 will reach 62 mph in just 4.9 seconds, which we’ll call very conservative, considering we scooted to 60 mph in 5.1 seconds in the regular 310-hp A7. Top speed is limited to 155 mph.
