Mazda 787B: Japan’s Le Mans Legend
Mazda 787B: Japan’s Le Mans Legend
In 1991, a screaming four-rotor Mazda did what no Japanese car had done before — win the Le Mans 24 Hours outright. It remains the only rotary-engined victory in the race’s history.
The Mazda 787B is one of the most beloved cars in motorsport history. At the 1991 Le Mans 24 Hours, it became the first Japanese car to win the race outright — and the only rotary-engined car ever to do so. Powered by the howling R26B four-rotor engine and driven by Volker Weidler, Bertrand Gachot and Johnny Herbert, the #55 car finished two laps clear of Jaguar. A rule change banned rotary engines for 1992, sealing its place in legend.

1. The big picture
The rotary rocket that beat the world at Le Mans.
The 787B is celebrated as much for its sound as its success.1 Its high-revving rotary engine produced a distinctive scream, and its 1991 win made it an enduring symbol of Japanese engineering ambition.
2. The 1991 victory
At the 1991 Le Mans 24 Hours, the Mazda 787B became the first Japanese manufacturer to win the race overall, with Johnny Herbert taking the chequered flag two laps ahead of the second-placed Jaguar, alongside co-drivers Volker Weidler and Bertrand Gachot.1 The lightweight car — around 830kg — was powered by the R26B four-rotor rotary engine producing roughly 700PS.
3. A one-of-a-kind place in history
Regulations introduced for 1992 effectively banned rotary engines, meaning the 787B’s win can never be repeated — it stands as the only rotary-powered victory in Le Mans history.1 Decades later it remains a fan favourite, regularly demonstrated at the circuit to the delight of crowds. ⚠ Historical detail — commemorative appearances vary by year.
