The Le Mans win in 1991 followed a decade of class wins from other Mazda prototypes, including the 757 and 767. The Sigma MC74 powered by a Mazda 12A engine was the first engine and team from outside Western Europe or the United States to finish the entire 24 hours of the Le Mans race, in 1974. Mazda is also the most reliable finisher at Le Mans (with the exception of Honda, which has entered only three cars in only one year), with 67% of entries finishing. Mazda returned to prototype racing in 2005 with the introduction of the Courage C65 LMP2 car at the American Le Mans Series race at Road Atlanta. This prototype racer uses the Renesis Wankel from the RX-8.
