The 1978 24 Hours of Le Mans was the 46th Grand Prix of Endurance, and took place on 10 and 11 June 1978.
In 1978, the Renault V6 turbo, which had lost in 1976 and 1977 to the Porsche 936, finally managed to beat the German cars. Each company had brought no less than four cars, which after qualifying shared the first four rows. After Renault's hare, the brand new A443, holed a piston late on Sunday morning, the modified A442B with its bubble roof was able to hold off Jacky Ickx and the remaining factory Porsches in the closing stages. Mission accomplished at Le Mans, Renault concentrated their efforts on Formula One.
