Featuring steep banking angled at 54 degrees, the 2,500-metre speed ring built the reputation of the autodrome. Born out of the passion of Alexandre Lamblin in 1924, Montlhéry played host, over the years, to world-famous races and world record attempts, and saw the best drivers in the world do battle. While it is no longer used for motor racing owing to safety requirements, the UTAC Linas-Montlhéry Autodrome is still a test centre for manufacturers and remains a popular venue for the organisation of events dedicated to collector vehicles.
