The Audi RS4 takes its place at the top of the A4 line. A 420hp V8 is capable of accelerating the lighter RS4 to 100 km/h in 4.8 seconds and 200 km/h in 16.6 seconds. The RS4 will be the first Audi model to apply a next-generation quattro drive system. More aluminum components have been used to remove excess weight out of the standard A4. A reduced ride height, larger brakes and 19-inch wheels complete the performance upgrades. Audi will only import approximately 300 of the limited edition RS4 Cabriolet.

The Audi RS4 is a limited production version of the A4 cabriolet. RS4 models feature a 420 hp 4.2L V8 engine.
