For the 1988 endurance season, Mazda presented a new car, the 767, which complies with the GTP regulation. Designed, like the 757C, by Nigel Stroud, the 767 was equipped with a 4-rotor engine, which gave a displacement of 5.2 liters and an output of 550-600 horsepower. The chassis and bodywork were completely redesigned compared to the 757C; the frame was lengthened to accommodate the bulkier engine. The 767 was stiffer than the 757C and could count on advanced aerodynamics, with a short tail and cantilevered wing according to the latest research trends. The 767 made its debut in Suzuka and entered the 24 Hours of Le Mans with two specimens, obtaining, despite various problems, a 17th and a 19th place. In the following years Mazda continued to use the 767 (version B), achieving some positive results, such as the GTP class victory at Le Mans in 1990.
