The 1979 24 Hours of Le Mans was the 47th Grand Prix of Endurance, and took place on 9 and 10 June 1979. With no other major works cars this year, the Porsche team were the strong favourites to win. Their competition would be from Cosworth-powered Mirages and Rondeaus and a swarm of Group 5 and IMSA-class Porsche 935s. The other big talking point was the presence of Hollywood actor Paul Newman, driving for Dick Barbour Racing.

The Mirage Lightweight Racing Car was a family of race cars built by J.W. Automotive Engineereing (JWAE) at Slough in England, initially to compete in international sports car races in the colours of the Gulf Oil Corporation.
