RS4 B5 Misano Red
In September 1999, Audi presented the RS4 as the successor to the RS2, which had been developed in collaboration with Porsche from spring 1994 to summer 1995. Unlike its predecessor, however, the RS4 was a product of the wholly-owned Audi subsidiary quattro GmbH, which has been responsible for Audi sports models since the end of the 1990s. Like its predecessor, the car was only available as an Avant (estate) and was based on the A4 of the B5 series.
