The Mercedes-Benz M 950 is a prototype Wankel rotary engine made by Daimler-Benz. It was first described in Wolf-Dieter Bensinger's 1969 essay Der heutige Entwicklungsstand des Wankelmotors, published in January of 1970. The engine was developed by Daimler-Benz's Wankel engine department, headed by Bensinger. About 100 units were built, of which some 3- and 4-rotor units were installed in the Mercedes-Benz C 111 experimental sports car, from 1969 until 1970, as a mid-engine. Although scheduled for commercial introduction in 1970 as a 2-rotor engine, the M 950 had not reached the series production stage by 1972. Daimler-Benz then developed a successor to the M 950, the M 951, but Daimler-Benz's Wankel engine development was abandoned in 1976.
