Lotus 25 Single Seater Championship Round 4

The Circuit des 24 Heures du Mans,[1] also known as Circuit de la Sarthe[2] (after the 1906 French Grand Prix triangle circuit) located in Le Mans, Maine, France, is a semi-permanent race course chiefly known as the venue for the 24 Hours of Le Mans auto race. Comprising private, race-specific sections of track in addition to public roads which remain accessible most of the year, its present configuration is 13.626 kilometres (8.467 mi) long, making it one of the longest circuits in the world. Capacity of the race stadium, where the short Bugatti Circuit is situated, is 100,000. The Musée des 24 Heures du Mans is a motorsport museum located at the main entrance of the venue.

Up to 85% of the lap time is spent on full throttle, meaning immense stress on engine and drivetrain components. However, the times spent reaching maximum speed also mean tremendous wear on the brakes and suspension as cars must slow from over 200 mph (320 km/h) to around 65 mph (100 km/h) for the sharp corner at the village of Mulsanne.
