The Circuit des 24 Heures du Mans, also known as Circuit de la Sarthe, located in Le Mans, Sarthe, France, is a semi-permanent motorsport race course chiefly known as the venue for the 24 Hours of Le Mans car 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 long, making it one of the longest circuits in the world.

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