In 1973, Toine Hezemans won the European Touring Car Championship in a 3.0 CSL and co-drove a 3.0 CSL with Dieter Quester to a class victory at Le Mans. Hezemans and Quester had driven to second place at the 1973 German Touring Car Grand Prix at Nürburgring, being beaten only by Chris Amon and Hans-Joachim Stuck in another 3.0 CSL. 3.0 CSLs would win the European Touring Car Championship again in every year from 1975 to 1979.

The 3.0 CSL was raced in the IMSA GT Championship in 1975, with Sam Posey, Brian Redman, and Ronnie Peterson winning races during the season.

The first two BMW Art Cars were 3.0 CSLs; the first was painted by Alexander Calder and the second by Frank Stella.

The 3.5 CSL was built for Group 5 racing and BMW won three races in the 1976 World Championship for Makes with this model.
