Two experimental versions of the BMW M1, designed to Group 5 specification, were built by both Swiss racing team Sauber, and British constructor March, in collaboration with BMW, for sports car racing, between 1979 and 1982.[6] It was far more developed and heavily modified compared to the BMW M1 Procars, which were built to the FIA Group 4 regulations.[7][8][9][10]
