The Mazda 767B made its motorsports debut on the track of the IMSA 24 Hours of Daytona in 1989. By the race's end, the 767B scored a respectable fifth-place finish, encouraging Mazda to test the car at other tracks. At the 24 Hours of Le Mans competition, two 767Bs finished in seventh and ninth places. The following year wasn't as promising for Mazda, as the 767B finished in 20th place.
