Mirage won its only overall 24 Hours of Le Mans victory in 1975.
The winning car was the Gulf-Mirage GR8, driven by Jacky Ickx and Derek Bell. It completed 337 laps, finishing ahead of another Cosworth-powered car, the Ligier JS2. A second Gulf-Mirage GR8 finished third, making it a remarkably strong result for the constructor.
Mirage was closely associated with designer John Wyer and Gulf Oil’s distinctive blue-and-orange racing livery. Its 1975 Le Mans triumph was especially notable because the race was not part of the World Championship for Makes that year, following changes connected with fuel-consumption regulations after the oil crisis.
The common mix-up is naming Gulf, Ford, or Cosworth as the winner. Gulf was the sponsor and Cosworth supplied the engine; the constructor of the winning prototype was Mirage. After 1975, Mirage continued at Le Mans but never again won overall.
