European Touring Car Championship
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.
