Mazda 767

The Mazda 767 and 767B are prototype racing cars that were built by Mazdaspeed for the 24 Hours of Le Mans running under the International Motor Sports Association-specification GTP class. The 767 replaced the 757 in 1988, upgrading to a newer and larger four-rotor 13J Wankel engine, which produced nearly 600 hp (450 kW). Two 767s were entered at 1988 24 Hours of Le Mans, finishing 17th and 19th overall, but they finished behind a sole 757, which was able to finish 15th. In the All Japan Sports Prototype Championship (JSPC), Mazda managed fourth in the constructors' championship. For 1989, Mazda upgraded the 767 into the 767B, and initially tested it in the International Motor Sports Association 24 Hours of Daytona, where it was successful in finishing fifth overall. Later in the year, Mazda returned to Le Mans with two 767Bs and an older 767. The 767Bs were able to finish seventh and ninth overall, while the lone 767 was able to finish 12th. However, in JSPC, the results were not as promising, as Mazda finished a mere 5th in the championship. For 1990, a single 767B was entered alongside two newer 787s, and was the only car of the three to finish, although in 20th overall.
