list of top sports cars of the 1970s. Motorsport In 1979 the head of BMW Motorsport, Jochen Neerpasch, devised a one-make championship using racing modified M1s. The series was created to aid BMW in building enough cars to enter the group 4 classification in the World Championship for Makes. The new series, known as the "Procar BMW M1 Championship", served as a support series for Formula One, and included many Formula One drivers in identical cars. The series ran for two years, with Niki Lauda winning the 1979 season, and Nelson Piquet the 1980 season. After BMW met the standards for group 4, the Procars were used by various teams in the world championship as well as other national series.
