Faroux became internationally known through the 24 Hours of Le Mans, which he established in 1923 together with Georges Durand and Emile Coquille. Durand and Faroux developed the first set of technical regulations. For more than three decades, the race director was often the last and many times the sole authority when it came to deciding which team to race. Between 1929 and 1955, Faroux was also a starter at the Grand Prix of Monaco.
