Le Mans: The Official History 1970-79

This decade at Le Mans began with the first victories by Porsche, whose awesome 917 racing car, capable of more than 240mph (385kph), established a distance record that would stand for almost four decades. One of a hat-trick of wins by Matra, effectively the French national team, was achieved in a famously frantic, head-to-head duel with Ferrari. In 1975, the oil crisis led the ACO to run its race to a ‘fuel formula’, and it was won by the Ford-supported Gulf-Mirage team.

• Porsche, using motorsport to develop its turbocharging technology, won again in 1976 and in 1977, when Jacky Ickx produced one of the greatest drives ever seen in motor racing anywhere. A massive effort by Renault, again with a turbocharged engine, delivered success in 1978. The decade closed, as it had started, with a soaking wet race that was won by Porsche.
• This 10-year chronicle describes events as they unfolded during each of the races. The reader will learn about the ever-changing regulations – many introduced to encourage fuel efficiency – that governed the races, and follow the technical advances made by innovative competitors as they strove to win the biggest prize in motor racing.
