The Mazda 737C was a prototype racing car built for Mazdaspeed for the 24 Hours of Le Mans under the Group C 2 formula. It was the final evolution of the initial Mooncraft built design dating back to the 717C. It again used a 2-rotor 13B Wankel engine.

Two 737Cs were entered in the 1985 24 Hours of Le Mans, finishing 3rd and 6th in the C2 class. The 737Cs were also raced in part of the 1985 World Sportscar Championship season, managing 8th place for Mazdaspeed in the C2 teams championship. In the All Japan Sports Prototype Championship, Mazda was able to come home 5th in the constructor's championship.

737Cs later ended up in the hands of privateers for the JSPC after Mazda replaced it with the newer 757.

24 Hours of Le Mans (1985)

Several improvements were made to the 737C car that was prepared for the 1985 Le Mans. The wheelbase was extended by 80 mm for greater stability, the body rigidity was enhanced and the suspension reworked. The 13B rotary engine also featured new carburetors and other updates. The 737Cs qualified in 40th and 44th place, but incurred a string of problems in the actual race. These included engine trouble, a flat battery due to faulty wiring of the dynamo, and damaged bearings in the gearbox. Against the odds both cars completed the race, but only managed third in class (19th overall) and sixth in class (24th overall).
