30 years ago, on 23 June 1991, the Mazda-787B car was the first in the 24-hour race at Le Mannes. It was the first and only case of victory in this prestigious competition of the Japanese brand car. Mazda-787B-Winner of the 24 Hours of Le Mans 1991 (Veydler/Gberbert/Gacho Crew). The car was prepared for Group C. The Japanese were an important victory because Mazda was actively conquering the European market with model 323, the predecessor of the current Mazda 3. The German car logs have once again awarded the Japanese small-scale prize for reliability and profitability. At the same time, the 787 cars of the 1990 24-hour race in Le Mans ended in two of the three cars due to problems with overheating of the powertrain (4-section rotary engine). And the third Mazda-787 finished only in the 20th position. Mazda-787B engine R26B had four sections with a working volume of 0.654 cubic meters. see Each (total-2,622 cubic meters) see ). Nippon Denso has been set up with electronic control. Each section had three spark plugs. Intake manifold for load moles change length (long, high-short at low speed). The engine issued a 700 L engine. at 9,000 rpm, but the prototype was significantly higher-930 l. c. at 10500 rpm The company brought the 7787B cars to the 59th race "24 Hours of Le Mans" in 1991. They were composed of Pierre Dudon, Takashi Yorino, Yujiro Terada (a car under the starting number 56), the Folmer Weidler, Johnny Herbert, Bertrand Gacho (No. 55) and Maurizio Sandro Sala, Stefan Johanssen, Dave Kennedy (No. 18). Car 18 had a lower ratio of the main pair, allowing it to save fuel. However, the speed was a couple of tens of kilometers below. Most of the pilots had a rich experience of performances at the All Japan Sports Prototypes Championship (AJSPC) and the World Sports Championship (WSC). Although the team's starting places were disadvantageous (19th, 23rd and 30th), car 55 was able to get close to the design workshop of the three Mercedes-Benz C-11 (one of the shift pilots of which Michael Schumacher was one of the replacement pilots). The Mercedes turned out to be weak opponents: one went down because of the gearbox problems, the other-because of problems. Mazda 787B and Herbert behind the wheel were driving the car at the 22nd hour of the race. He even refused to leave the cockpit in the clock to keep the pace. He came first, with 362 laps and 4,932.2 km away. The following year Federation Internationale de l' Automobile (FIA) banned the use of rotary piston engines in sports prototype races. So the 787B victory in 1991 was also the only victory of the Rotoro-piston car in Le Mans ' history.
