A Pair of Twin Turbo V-8 for the Four S?s

Audi?s performance quotient takes a big jump as the company lifts the hood on a pair of new twin turbo V-8s powering four new S models.? Debuting at the Frankfurt Motor Show are the new S6, S6 Avant, S7 Sportback and S8 performance models, all which are scheduled to arrive in showrooms in spring 2012.

The new engines include start-stop systems and a new ?cylinder on demand? cylinder management system, which shuts down four cylinders during light load driving. ?An Active Noise Cancellation system activates when the engine is in its four-cylinder mode.? Four microphones integrated into the headlining record the noise in the cabin, which is then analyzed by a computer. ?If the computer detects intrusive sound elements, it broadcasts an antiphase sound through the speakers of the sound system and largely cancels it out any intrusive noise caused by the engine.

All three cars share the fast-shifting, seven-speed S tronic transmission and quattro permanent all-wheel drive with a self-locking center differential and torque vectoring.
