2007 Audi RS 4

The 2007 Audi RS 4 is powered by a lightweight and high-revving 4.2-liter V8 with FSI direct injection that produces 420 horsepower at 7800 rpm and 317 lb-ft of torque at 5500 rpm, with 90 percent of peak torque available from 2250 to 7600 rpm. A 6-speed manual transmission is standard and the quattro all-wheel-drive system uses a Torsen center differential to distribute 60 percent of torque to the rear wheels and 40 percent to the front under normal conditions. Braking performance is comparable to a race car with 14.4-inch two-piece front disc brakes fitted with 8-piston calipers. RS 4 features Audi’s Dynamic Ride Control suspension which is a mechanical system that reduces body roll and pitch by interconnecting the suspension dampers diagonally through a central valve.
