Mazda entered two 767s and one 757 for the 1988 Le Mans. From the beginning of the race, several works Porsches and Jaguars formed a closely fought lead group. The remaining cars formed a second group someway behind. The two 767s were gradually climbing up the second group when, at 6:50 a.m. on the second day, one of the cars made a scheduled pit stop. The mechanics discovered a crack in the exhaust manifold and broken teeth on the water pump belt. Just three minutes later, the other 767 came into the pit with the same trouble. By the time all the damaged parts were replaced, both cars had dropped a long way down the order.
  At the finish, the 757 stood in 15th position, with the 767s in 17th and 19th (first, second and third in the IMSA GTP class). Although the result was not what the team was aiming for, all three cars successfully completed the race.
