The Mazda 787 and 787B race cars were built to compete in the World Sportscar Championship, the 24 hour Le Mans, and the All Japan Sports Prototype Championship between 1990 and 1991. It was the last time Mazda used the Wankel engine to power its race cars on a World Championship and Japanese Championship level.
