The 1953 24 Hours of Le Mans was the 21st Grand Prix of Endurance, and took place on 13 and 14 June 1953, at the Circuit de la Sarthe, Le Mans (France). It was also the third round of the F.I.A. World Sports Car Championship. British drivers Tony Rolt and Duncan Hamilton won the race with one of three factory-entered Jaguar C-Types, the first cars ever to race at Le Mans with disc brakes. Regulations With the ongoing success of the World Championship of Drivers, this year saw the introduction by the FIA of a World Championship for Sports Cars, creating great interest from the major sports car manufacturers. It also drew together the great endurance races in Europe and North America. The Le Mans race was the third round in the championship after the 12 Hours of Sebring and the Mille Miglia. After the efforts by drivers in the recent races to drive almost single-handedly (Chinetti in 1949, Rosier and Hall in 1950, Levegh and Cunningham in 1952) and the consequent safety danger through exhaustion, the ACO set limits of maximum driving spells of 80 consecutive laps and 18 hours in total for each driver. This year also marked the first use of a radar-‘gun’ to measure speeds across a flying kilometre on the Hunaudières Straight. The Cunningham would touch almost 156mph. Some 6 mph faster than last years winning Mercedes gull wing coupe. These results, not surprisingly, aligned with engine size but, significantly, also the impact of aerodynamics on top speed: Entries The prestige of the race, as well as the advent of the new championship generated intense interest in Le Mans. Of the 69 entrants and reserves, nineteen different marques (and their subsidiaries) were present. There were an unprecedented 56 works-entered cars officially represented, with over half in the main S-8000, S-5000 and S-3000 classes. Mercedes-Benz did not return to defend their title – they were busy preparing new cars for both the F1 and Sports Car championships. So the overall victory was shaping up as a contest between Italy (Scuderia Ferrari, S.P.A. Alfa Romeo and Scuderia Lancia), England (Jaguar supported by Aston Martin, Allard and Nash-Healey/Austin-Healey and the United States (Cunningham), with the French (Talbot and Gordini) being the ‘dark horses’. Drivers included all three F1 World Champions to date (Alberto Ascari, Juan Manuel Fangio, Giuseppe Farina) and over 30 other current and up-and-coming Grand Prix
