Despite the high terminal velocity of the Alpine Porsche had the faster car for one round. Three 936 were taken to Le Mans. Jacky Ickx drove in 936/78 in training with the fastest lap time 3.27.060. The Belgians shared the cockpit as the previous year with Henri Pescarolo. Ickx had already won the race four times, and was next to his compatriot Olivier Gendebien record winner.

The race course
Although Jacky Ickx started the race from pole position, frustration set out in the Porsche Box after a few rounds wide. The carriage of Ickx and the Haywood / Gregg vehicle stood with gearbox problems in the pits and lost valuable time on the now walking in leadership Alpine - Renault. In the first hours of the race there were a stable triple guidance for Renault, with the Jassaud / Pironi cars at the top. Only the Barth / Wollek - Porsche was able to ride the pace of the trio approximate. When Henri Pescarolo came again to a long repair to the box, Jacky Ickx was reacted as in the year before in another car: he came to Jürgen Barth and Bob Wollek the team. His place as a partner of Pescarolo took Jochen Mass, who had an accident with the 936 after 255 laps and was eliminated.
And as in the previous Ickx took the Porsche back to the top, until Sunday morning broke the fifth gear. Meanwhile, led by Jean-Pierre Jabouille and Patrick Depailler, and Renault got problems. The Jaussaud / Pironi cars also had gearbox problems and dropped back to third place. Jean -Pierre Jabouille finally retired with engine failure, but because of the ongoing problems with the Porsche transmission in Ickx cars were victorious at the end of Jean -Pierre Jaussaud and Didier Pironi safe with five laps.
It was the first overall victory for Renault in Le Mans. The state-owned company had thus reached his big goal and put the end of the sports car program.
