Like its predecessor, the car was only available as an Avant ( station wagon ) and was based on the A4 of the B5 series . The vehicle, only available in Europe, was offered from the end of 1999 at a base price of around 127,000 DM.

Production of the first RS4 ended in September 2001 after 6030 copies. Initially, only half as many were planned, but demand was so high that Audi doubled production. The last vehicles were registered as vehicles of the model year 2002.
