BMW V12 LMR

The BMW V12 LMR is a Le Mans Prototype built for sports car racing from 1999 to 2000 through an alliance between BMW Motorsport and Williams Racing, the successor to the failed V12 LM of 1998. It is famous for earning BMW its only overall victory to date at the 24 Hours of Le Mans. After both V12 LMs failed to finish the 1998 race because of mechanical trouble and a slow pace caused by aerodynamic inefficiency, BMW Motorsport decided to revamp the sportscar project radically and replace the car quickly for 1999. The V12 LMR kept only the basic structures of the V12 LM and all of its bodywork was redone from scratch; the cooling ducts, a major problem on the V12 LM, were moved to the top of the car, and among the more radical features was a small roll hoop only behind the driver's seat.
