Deutsche Rennsport Meisterschaft (translated as German Racing Championship) or simply DRM as it was known, was a touring car and Sportscar racing series. It is regarded as a predecessor of the current DTM as Germany's top national series.^[1][2][3][4]

The DRM began in 1972 as a Group 2 touring car and Group 4 GT racing series for cars like (BMW 2002) and (BMW Coupé), in addition to the Deutsche Rundstrecken-Meisterschaft [de] (German circuit racing saloon car championship).^[5] In these years, the same or similar cars were also entered in the European Touring Car Championship.

Races were run separately as big Division 1 (for 2 to 4 liter) and small Division 2 (under 2 liter) in a sprint format.^{[citation needed]}

In 1977, Group 5 cars were admitted into the series, making the series better supported with Group 5 cars than the World Championship of Makes they were intended for.^{[citation needed]} These fast and spectacular turbocharged cars with wide fenders and wings were initially popular, but they were proved to be expensive with each round struggling to bring in more than 10 cars for each class during the 1978 season. At the same season, it became clear that a turbo-charged engine was a necessity to maintain competitiveness, especially in Division 2.^[6][7] Not even a weight increase (up 885kg from 735kg) for the 1979 season could prevent this.^[8]

In 1979, the Rennsport Trophäe (Racing Trophy) was introduced for the cheaper original series protagonists, the Group 2 and 4 cars.^[5][8] 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 DPM (Deutsche Produktionswagen Meisterschaft), run with Group A cars.

1985 was the final year of the now called DSM (German: Deutsche Sportwagen Meisterschaft, lit. 'German Sportscar Championship'), with just one race was held at Norisring, the rest of them held in conjunction with the popular Interserie. This meant CanAm entered from the latter series, as it had always been, had to be counted for points

The series would be replaced by the Group C-only Supercup in 1986. At that time, the less expensive DTM (German: Deutsche Tourenwagen Meisterschaft, lit. 'German Touringcar Championship') had taken over as Germany's most important racing series.

Since 2005 the AvD the AvD organizes a "Revival Deutsche Rennsportmeisterschaft" race at his great "Oldtimer Grand Prix".
