Jean RONDEAU was born in Le Mans, and like many of his fellow citizens, he quickly became a fan of race cars, especially those that take part in the 24 Hours of Le Mans.

Before becoming a manufacturer, Jean RONDEAU was a race driver, namely with a CHEVRON B21 in Le Mans in 1972. In 1975, he decided to build his own cars with the support of INALTERA, a wallpaper manufacturer, and with the help of G. WELTER, a Peugeot designer. Two cars took part in the 24 Hour race in 1976, and made it to the end!

In 1978, the cars bear the name of RONDEAU. He manages to win the event in 1988 at the wheel of his own car: a unique occurrence in the annals of the 24 Hours of Le Mans.

17 sport prototypes were built between 1978 and 1982, all inspired from studies carried out during the INALTERA period, then adapted to the regulations, which changed almost every year, for the category of the respective event, and to the chosen engine

Seven 382 chassis were built, of which 2 were transformed to change from a 3.3 litre COSWORTH V8 FORD engine to a 5’900 cm3 CHEVROLET V8. It is one of these two that has been examined. It took part in the 24 Hours of Daytona in 1982, in the hands of Danny SULLIVAN and Gary BELSCHER, the RONDEAU importer in the USA. It was driven twice by Jean RODEAU himself in 1984
