The 1927 24 Hours of Le Mans, the 5th Grand Prix of Endurance, was a motor race which took place at the Circuit de la Sarthe on 18 and 19 June 1927. The race was one of the most remarkable and dramatic pre-war Le Mans races. It is commonly remembered due to the infamous White House crash, a major accident that involved eight cars including all three of the widely tipped Bentley team's entries, and caused the retirement of two of them. The race was eventually won by the third which, although badly damaged, was able to be repaired by drivers Dudley Benjafield and Sammy Davis. It was Bentley's second victory in the endurance classic. In a race missing many major manufacturers, the three Bentleys had been comfortably leading from the start, putting a lap on the rest on the field. The accident occurred about 9.40pm, as night was falling and a drizzle had started. A 2-litre Th. Schneider had spun at the White House curves blocking the road when the lead Bentley, unsighted, hit it at speed. Davis was able to extricate his damaged car and get back to the pits, resuming the race after a half-hour repair. The French Ariès of Jean Chassagne and Robert Laly, the only other large-engined car in the race, had meanwhile taken the lead. They held it through a very wet night and into the Sunday, until stopped with less than two hours to go by a broken distributor. Davis and Benjafield had pushed their mishandling car hard all the way to take a lauded victory, in the end by a considerable 20-lap margin. Regulations This year the Automobile Club de l'Ouest (ACO) lifted the minimum production required from 10 to 30 cars. A new dispensation for 1100 to 1500cc was to let them have only three seats. Crucially this removed 60 kg of compulsory ballast from them. Once again the ACO adjusted the Index target distances; although for the first time there was a reduction in target – in the smallest-engined cars. Example targets included the following: Grand Garage Saint-Didier, the large Parisian car-dealership sponsoring the Index competition, boosted its prize-money to a substantial FF50000. Concerned about the advent of specialised racing fuels with expensive high-octane ratings, the ACO now dictated that all cars had to use the same commercial-grade gasoline. This raised many complaints from the teams concerned about the effects
