Rondeau M 378 at Le Mans in 1978. The car used a Ford Cosworth 3 litre engine and was driven by Jean Rondeau seen in the car, Jacky Haran and Bernard Darniche. They finished in 9th place overall. This was the third time that Jean Rondeau had won the GTP category at Le Mans. In 1980 he won the race outright (sharing with Jean Pierre Jaussaud) and so became the only person to win Le Mans in a car bearing his own name which he had designed.
