The BMW E9 is a range of coupés produced from 1968 to 1975. Initially released as the 2800 CS model, the E9 was based on the BMW 2000 C / 2000 CS four-cylinder coupés, which were enlarged to fit the BMW M30 six-cylinder engine. The E9 bodywork was built by Karmann.

As a racing car, the E9 was very successful in the European Touring Car Championship and the Deutsche Rennsport Meisterschaft, especially the 3.0 CSL homologation model.

The E9 range was replaced by the E24 6 Series.
