class which were subject to greater restrictions than the newly introduced C1 class in which the cars were fitted with 3.5-litre Formula One inspired naturally aspirated engines. The third car was built primarily to replace the Le Mans winning car in competition but it retired in 1992 with no notable success. Racing history 1990 The first 787 chassis made its competition debut in April 1990, at the second round of the All Japan Sports Prototype Championship (JSPC) season. For the Inter Challenge Fuji 1000 km, Mazdaspeed entered their 787 alongside an older 767B chassis, with Yoshimi Katayama, David Kennedy, and Pierre Dieudonné in the new car. After Fuji, the second 787 chassis was completed, and the team departed for Europe to prepare for Le Mans. Tests were performed at the Silverstone Circuit in Great Britain and Autódromo do Estoril in Portugal to prepare the car's setups and test its endurance. A total of were completed over the tests. Former Le Mans-winner Jacky Ickx was hired by Mazdaspeed in order to prepare the two 787s, as well as an older 767B, for the race. Driver Stefan Johansson joined Kennedy and Dieudonné in the first car, and Bertrand Gachot, Volker Weidler and Johnny Herbert were hired for the second entry. The all-Japanese line-up of Katayama, Yojiro Terada and Takashi Yorino remained in the 767B. In qualifying the new 787s set the 22nd and 23rd fastest lap times, ahead of the 767B's 34th fastest time. The two 787s ran reliably for much of the race, lasting through the night until problems were encountered in the early hours of Sunday morning. While leading their GTP class, an oil leak on the No. 201 entry for Kennedy, Dieudonné, and Johansson forced the team to retire the car. Two hours later, the No. 202 787 was also retired after an electrical failure and fire. Heat from the engine was blamed for both failures. The 767B, the only car remaining in its class, survived until the end of the race and finished 20th. After Le Mans, Mazdaspeed withdrew the remaining 767B from competition. Two 787s were entered for the rest of the JSPC season with the Japanese trio of drivers in one entry and Kennedy and Dieudonné remaining in the other. Returning to Fuji, the 787s earned fifth and tenth-place finishes in a 500 km event, although the fifth-place finisher was later disqualified due to a fuel
