The power is channeled — in typical Audi style — to all four wheels, but not through a seven-speed dual-clutch transmission (which wouldn't be able to handle all the muscle the RS7 has on tap), but instead through a more robust eight-speed automatic transmission.

Debuting alongside a revised Mercedes-Benz CLS63 AMG and BMW M6 GranCoupe at the North American International Auto Show in Detroit just last month, the new Audi RS7 is the latest in a string of German high-performance fastbacks that offer all the speed and cachet you'd expect from a sportscar, only with an extra set of doors and seats so you can bring your best friends along for the ride.
