11. Seventh overall and a third straight GTP class win at Le Mans1989
The problems that had struck the 767s in 1988 were investigated and remedied, and three improved 767Bs were entered for the 1989 Le Mans. Development of the 767B had focused on three main areas: increasing power output from the 13J-M engine at low to mid engine speeds, reducing weight and enhancing the aerodynamics.
All three cars started well, and sped through the first 12 hours without encountering any major problems. As they passed the morning of the second day, the 767Bs actually increased their pace and went on to cross the finish line in formation. The lead Mazda took seventh overall, equaling the best result ever achieved by a Japanese make, and won the IMSA GTP class for the third year in a row. The other 767Bs finished in ninth and twelfth overall and earned Mazda an impressive 1-2-3 in the GTP class.
