The Wankel rotary engine that powered the Mazda 787B to victory at Le Mans in 1991 represents one of the most innovative powerplants in motorsport history. Unlike conventional piston engines, the rotary design uses a triangular rotor spinning within an epitrochoidal chamber.

This unique configuration delivers exceptional power-to-weight ratio and incredibly smooth operation. The 787B's 2.6-liter four-rotor engine produced over 700 horsepower while weighing significantly less than equivalent piston engines.

The 787B remains the only Japanese car and the only rotary-powered vehicle to win the 24 Hours of Le Mans, cementing Mazda's place in racing history.
