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. The 2800CS was replaced by the 3.0 CS and 3.0 CSi. In 1973, Toine Hezemans won the European Touring Car Championship in a 3.0 CSL and co-drove with Dieter Quester to a class victory at Le Mans.
