Mazda 787B

The 787B is the only rotary-engined car — and until 2018 the only Japanese car — to win Le Mans overall, its 1991 victory and banshee four-rotor soundtrack making it perhaps the most beloved single racing car Japan has produced.

History

Mazdaspeed's Group C programme spent the 1980s as Le Mans' persistent underdog, evolving rotary prototypes (717C through 767B) that finished but rarely threatened. The 787 of 1990 and definitive 787B of 1991 changed the calculus: the R26B four-rotor produced around 700 hp with remarkable fuel efficiency under the race's equivalency rules, housed in a Nigel Stroud-designed carbon/Kevlar monocoque with famously slippery bodywork.

At Le Mans 1991, the no. 55 car in Renown's orange-and-green charged as the favoured Sauber-Mercedes fleet hit trouble; Weidler, Herbert and Gachot brought it home two laps clear — Johnny Herbert so drained he missed the podium. The win came in the rotary's final eligible year, sealing the engine type's only Le Mans victory in the race's history.

Mazda has treated the achievement as corporate treasure ever since: chassis 002, the winner, is preserved and regularly demonstrated (its 2011 return to Le Mans drew crowds rivalling the race), while sister 787/787B chassis appear at Goodwood and Japanese heritage events. The handful of cars exist between Mazda's ownership and a tiny circle of collectors; a genuine 787-family transaction is a once-a-decade event priced accordingly.

Palmarès

Overall victory, 1991 24 Hours of Le Mans (no. 55, Weidler/Herbert/Gachot) — the rotary engine's only win and Japan's first; strong JSPC campaigns including podiums against works Nissan and Toyota turbos; and sister-car top-ten Le Mans finishes 1990–91 that underline the win was pace plus preparation, not merely attrition.

What to check before you buy

Realistically, the market is 767/787-family cars other than the winner: verify chassis identity through Mazdaspeed records and period JSPC/Le Mans entry lists, the R26B's rebuild status (a handful of Japanese specialists and Mazda's own heritage shop service four-rotors), and originality of the Stroud tub. Demonstration-readiness — fresh fuel cells, rotor housings, electronics — is a six-figure line item on its own. Expect any genuine car to transact privately with Mazda's heritage operation involved or at least informed.

Did you know

  • The R26B's ceramic apex seals and continuously variable intake trumpets pushed rotary efficiency to levels road RX models never saw — Le Mans' fuel rules forced the innovation.
  • Johnny Herbert dehydrated so severely in the final stint that he was taken for medical care instead of the podium — he finally 'received' the celebration at Le Mans twenty years later.
  • After the 2011 demonstration, Le Mans organizers let the 787B's four-rotor scream down the Mulsanne once more — spectators voted it the weekend's highlight over the actual race.
