Following on from the RS2 Avant, the Audi RS4 was only available in Wagon form and was developed upon the B5 platform used by the Audi A4 and S4. 6,030 units were produced by Audi between 1999 and 2001.
The RS4 was endowed with wider wheel arches to house the wide axle tracks and bigger tyres, this also proved beneficial to the looks of the car with a wider more aggressive stance. The bumpers and side sills were also changed from the S4, helping to achieve a low drag coefficient Cd 0.34.
