cell that was too large. Tenth place was again earned at the 1000 km of Suzuka, although the all-Japanese entry retired after an engine failure. A similar result occurred at Sugo, except it was the Japanese squad that finished eleventh while the international squad had an engine failure. For the last event of the season, the 1000 km of Fuji, Mazdaspeed entered the two 787s and a 767B, brought out of retirement. It finished sixth: one 787 was seventh and the other retired following a transmission failure. Mazdaspeed's Yoshimi Katayama earned 25th in the drivers' championship, and Mazda was fourth in the constructors' championship. 1991 For the 1991 season, Mazda expanded their efforts with the 787. Two cars were assigned to the JSPC series, while a third car ran the full Sportscar World Championship season for the first time, with drivers David Kennedy, Maurizio Sandro Sala, and Pierre Dieudonné assigned to the team. The French Oreca team were put in charge of the world championship campaign. Oreca and team consultant Jacky Ickx were able to persuade FISA that the 787s should be allowed to run with less weight than their competitors, leading to FISA allowing the team to run the cars at rather than the standard required for the C2 class. Unlike the JSPC series, FISA had begun to integrate regulations for a new engine formula in the world championship, which required all teams to use 3,500 cc engines by 1992. Cars that met these regulations in 1991 became the top C1 class, while cars with other engines, including the 787, were reclassified as C2. The C2 class cars also retained the fuel consumption formula that group C had been founded on, while C1 cars no longer required it. This meant that Mazda now had to fight for class wins within their new class. In the JSPC, however, Mazda's 787s remained in the GTP class, as the sole competitors in the category. The year started in Japan, with Mazdaspeed entering two older 787s while the new 787Bs were being finalised. Both cars suffered problems and were uncompetitive. Attention then turned to the Suzuka Circuit, where the début race of the world championship season was being run. The first new 787B chassis arrived alongside an older 787. The newer car, with Sandro Sala and Kennedy, out-qualified the older chassis driven by the all Japanese squad by only an eighth of a
