With the demise of the Deutsche Rennsport Meisterschaft, a new top-series for Touring Cars was called for in Germany. And after an impressive demonstration of the French Supertourisme championship at the German GP in 1983, it was decided to follow those steps; Group A cars combined with weight and tire width penalties. At the same time, the cars were not allowed to make more that 100 dB noise - which took away some of its popularity.

Additional weight for 3- or 4 valve engines: 70 kg.
The ONS could penalize a too dominant car with extra weight up to 120 kg and/or limit the tire width. An uncompetitive car could have its weight further reduced and/or use wider tires.
