Have you stopped drooling like one of Pavlov’s dogs? I sure haven’t. But watching that video of Mazda’s brilliantly wild 787 running Le Mans conveys just a small portion of the rotary’s racing pedigree.
Throughout the years, Mazda dropped two-, three-, and four-rotor rotary engines into a number of different applications, including top-tier IMSA sports car racing, prototypes like the 767 and 787 cars, open-wheel cars, and a secret Group B rally prototype with an 11,000-RPM two-rotor RX-7. Mazda’s first rotary win came in 1972 when a two-rotor RX-2 sports car won an IMSA RS race at Lime Rock Park.
Mazda found success in its RX series, winning races with the RX-2, RX-3, and RX-7. And with the introduction of the RX-7, it went on a winning streak snatching its class podium for 10 years at the 24 Hours of Daytona. It also won the IMSA Grand Touring Championship Under Two Liters every year between 1980-1987.
The rotary’s biggest claim to fame in racing, however, came in 1991 when a four-rotor 787B prototype racer, the one in the video above, won the 24 Hours of Le Mans outright. It not only became the first and only rotary engine to win the famed race, Mazda became the first-ever Japanese constructor to win, too. Neat!
What Models Currently Feature a Rotary?
None. Mazda kept it alive for as long as it could, but it was dropped from the lineup in 2012 when the RX-8 was retired. Mazda says it’s bringing back a rotary engine, though it will be used as a range extender in one of the company’s forthcoming hybrid cars. Not exactly the triumphant return of the legendary engine.
