rdf:langString The 1933 24 Hours of Le Mans was the 11th Grand Prix of Endurance. It took place at the Circuit de la Sarthe on 17 and 18 June 1933. Up against five strong privateer entries from Alfa Romeo, the opposition looked fairly weak, mostly being of 1920s vintage. There was a strong British contingent in the smaller classes. The big drawcard was the presence of top European drivers Louis Chiron and Tazio Nuvolari. The current European champion was paired with one of the previous year's winners, Raymond Sommer From the start, the Italian cars set a strong pace. Sommer broke the track-record several times building a two-minute lead over the Alfas of Chiron, Lewis, Chinetti and Moll. He had lapped the rest of the field by the end of the second hour. Chiron was delayed by an intransigent starter unit, but his co-driver Franco Cortese drove hard to bring the car back up to second going into the night. Most of the other large-engine contenders had fallen away, allowing Odette Siko in a 1.8-litre supercharged Alfa Romeo to move up to fifth. The British teams of Aston Martin, Riley and MG filled out the back end of the top-10. A processional first half of the race was turned on its head come the dawn on Sunday when Nuvolari brought the leading Alfa in with fender damage and a leaking fuel-tank. The two-lap lead they had built up was lost in the quarter-hour needed for repairs. The Chiron and Chinetti cars then swapped the lead for the next two hours in close, exciting racing. At 7am a short rain-shower caused Odette Siko to have a serious accident on the fast approach to Indianapolis corner. The car was wrecked as it ploughed into the trees but fortunately the driver was thrown clear and only lightly injured. Hard work by Nuvolari, who was fresh after avoiding driving during the night, had got him back in front by 9am. Soon after, Cortese crashed when a front wheel bearing collapsed. With the closest opposition gone, what could have been a simple run to the finish was anything but. When Sommer pitted the car at midday, their lead was again wiped with repairs to the radiator, brakes and worsening fuel-leak. Mechanics used chewing-gum to plug the crack. Nuvolari would then overtake the smooth-running Chinetti/Gunzberg car only to have to stop to check the fuel-tank and lose the lead again. By the time of the final stops, with an hour to go, the two cars were less than a minute apart. Going onto the last lap, the superior speed of Nuvolari's car allowed him to pass on the back straight, only to lose it again under braking at the Mulsanne corner. Then Chinetti missed a gear at Arnage and Nuvolari was through again. When Chinetti was baulked by slow traffic coming out of White House it gave Nuvolari the clear run to the flag, to win by just 400 metres. The margin of victory for this race was estimated at being 9.5 seconds difference and remains one of the narrowest racing finishes at Le Mans – excluding the formation finishes of later years. Third, eight laps back, was the British-entered Alfa Romeo of Lewis/Rose-Richards. Fourth, after a very reliable run was the small 1.1-litre Riley of Peacock/van der Becke. Their excellent effort against the larger competition also gave them a handsome margin in winning the lucrative Index of Performance prize.
