Mercedes-Benz M 950 er en prototype Wankel-motor. Den ble først beskrevet i Wolf-Dieter Bensingers essay "Der heutige Entwicklungsstand des Wankelmotors" fra 1969, publisert i januar 1970.
Motoren ble utviklet av Daimler-Benz sin Wankel-motoravdeling, ledet av Bensinger. Rundt 100 enheter ble bygget, hvorav noen 3- og 4-rotorenheter ble installert i Mercedes-Benz C 111 eksperimentelle sportsbil, fra 1969 til 1970, som en midtmotor.
Selv om M 950 var planlagt for kommersiell introduksjon i 1970 som en 2-rotormotor, hadde ikke M 950 nådd serieproduksjonsstadiet i 1972.
Daimler-Benz utviklet deretter en etterfølger til M 950, M 951, men Daimler-Benz sin Wankel-motorutvikling ble forlatt i 1976.

The extremely rare (12 total built) Mercedes-Benz M950F was a normally aspirated Wankel engine mounted in experimental Mercedes-Benz C111 vehicles, built in 1969-70. There were two versions: 3-rotor engine (600 cc each) with power output of 280 hp at 7000/min, and a later version 4-rotor engine (600 cc each) with power output of 350 hp at 7000/min.
The experimental Mercedes-Benz C111 containing the (code named M950F) engine was shown to the public at the 1969 Frankfurt International Motor Show.
This was a totally experimental car from Daimler-Benz, and they gave up on the rotary due mainly to poor fuel consumption.
