The DRM began in 1972 as a Group 2 touring car and Group 4 GT racing series.
Races were run separately as big Division 1 (for 2 to 4 liter) and small Division 2 (under 2 liter) in a sprint format.
In 1977, Group 5 cars were admitted into the series, making the series better supported with Gr.5 cars than the World Championship of Makes they were intended for. These fast and spectacular turbocharged cars with wide fenders and wings had many fans.
In 1979, the Rennsport Trophäe (Racing Trophy) was introduced for the cheaper original series protagonists, the Group 2 and 4 cars. It consisted of combined races with the DRM until 1981.
In 1982, following the FIA rule changes, new Group C sportscars (along with existing Group 6) replaced the Group 5 machinery at the renamed International Deutsche Rennsport Meisterschaft. Meanwhile, the Rennsport Trophäe held separate races and events in 1982 and 1983, except for the 1982 ADAC Eifelrennen at the Nürburgring Nordschleife.
In 1984, with just three races held, organisers used three WEC (World Endurance Championship) races as additional IDRM point races. Also, the Rennsport Trophäe was replaced by the Deutsche Tourenwagen Meisterschaft, run with Group A cars.
