context_page_description: Jean Rondeau was a French race car driver and constructor, who won the 24 Hours of Le Mans in 1980, in a car bearing his own name, an achievement which remains unique in the history of the race.
context_section_description: Jean Rondeau joined an effort to develop a Group Six race car to replace those of the French factory teams that withdrew from the class in 1975.  The original project was centered on use of a 2.7 L Peugeot V8, but Rondeau was convinced that the more powerful Ford-Cosworth DFV V8, which had powered the winning car in the 1975 24 Hours of Le Mans, had greater prospects for success.  After picking up sponsorship from the French wallpaper company Inaltera, Rondeau built group of six cars eligible to compete in the GT prototype class.  Rondeau's factory, similarly to those of Courage and Pescarolo Sport, was based near Le Mans. The first Rondeau-built car to compete at Le Mans was the Inaltera GTP in 1976.  It achieved GTP class wins against Peugeot, Aston-Martin, and Ferrari powered cars for two consecutive years, in 1977 placing fourth overall and 27 laps behind the race winner.
  After Inaltera withdrew its support, Rondeau picked up sponsorship from the elevator company Otis and built a slightly modified version of the Inaltera cars bearing his own name.  The Rondeau M378 was introduced in 1978 and the M379 was unveiled the following year.  Lackluster finishes in 1978 and 1979 fed the common regard of the DFV motor as uncompetitive in Group Six for want of an adequate combination of power and reliability.  The Rondeau team then scored surprise first and third-place finishes in 1980 with the M379B.  With that win Rondeau became one of two independent builders, not associated with a major manufacturer, to win at the 24 Hours of Le Mans since the event resumed in 1949. In 1981 Rondeau entered five cars, finishing second and third. However, this was overshadowed by the death of Rondeau team driver Jean-Louis Lafosse in the early hours of the race after crashing out on the Hunaudieres straight. Rondeau cars would never again approach those heights at Le Mans.
  In 1982  the Rondeau team made a strong bid for the manufacturers' title in the World Endurance Championship with a win at the Monza 1000 km event and two other podium finishes that yielded a close second-place ranking behind Porsche in season points.  The new 3.3 L and 3.9 L Cosworth DFL motors showed inadequate reliability for Le Mans, however, with all three works M382s retiring with mechanical failures.  A controversial FIA ruling allowed Porsche to claim points from a privately entered 911 at the Nurburgring race, which gave the title to the German company. Rondeau's main sponsor, Otis, were so incensed that they withdrew sponsorship of the French concern.  The 1983 season saw Otis replaced with Ford as Rondeau's main supporter and the entry of the new M482 at Le Mans.  The inadequate reliability of the DFL motors and Rondeau's problems developing ground effects aerodynamics suggested that Rondeau would never again be competitive without major car and motor development that were beyond their means.  Rondeau's team was disbanded at the end of 1983.
  The Rondeau car was last seen at Le Mans in 1988 in privately run hands; Pescarolo has since occasionally run one of the M379Bs in historic competition. A total of 19 Rondeau chassis were constructed, of which 17 remain in existence.
