In 1997, BMW announced that it had formed a partnership with Williams Grand Prix Engineering in order to provide V10 engines in 2000. The initial development of this partnership was BMW's sports car effort. Chassis built by Williams powered by a BMW M70 V12 engines were entered by long-time partner team Schnitzer Motorsport. The rather unsuccessful 1998 model was improved, and the efforts culminated in BMW's victory at the 1999 24 Hours of Le Mans with the BMW V12 LMR. Additional success came in the 2000 ALMS series before the cars were retired from racing.
