The golden years of DTM

The original DTM was started in 1984 as Deutschen Produktionswagen Meisterschaft (German Production Car Championship), with cars entered by privateer teams and under FIA Group A rules, but was extensively modified throughout the years, allowing more modifications. In the late 1980s, works teams joined the DTM, and it became one of the most popular motorsport championships in Europe. Turbochargers were banned at the start of 1990 season due to cost reasons. In 1993, the Group A rules were abandoned in favor of a more liberalised 2.5 L engine category called FIA Class 1 Touring Cars, with extensive use of ABS, four-wheel drive, electronic driver aids and carbon fibre chassis, the former three were technologies that were banned from F1. Opel, Mercedes-Benz and Alfa Romeo all fielded works teams after Audi and BMW had abandoned earlier. When driving for fun, not money!
