1934 24 Hours of Le Mans

The 1934 24 Hours of Le Mans was the 12th Grand Prix of Endurance. It took place at the Circuit de la Sarthe on 16 and 17 June 1934. Four privateer Alfa Romeo entries were expected to fight for outright honours, with an outside chance for the four Bugattis ranged against them. British cars dominated the smaller classes. Two-time winner Raymond Sommer soon took the lead until, after only 90 minutes, he stopped out on the circuit with smoke pouring from his engine. For the next five hours the Alfas of Luigi Chinetti and Earl Howe duelled for the lead. However, soon after night fell, the lights failed on Howe's Alfa costing him two hours to get the electrics repaired. Chinetti took the lead, but their car had developed a leak in the fuel tank. The solution was the same as Sommer had used the previous year: to plug the gap with chewing-gum.

By the halfway point, there was only a single competitive big-engine car left running, and interest shifted to the race for the Index of Performance between the four British firms of Aston Martin, MG, Riley and Singer. For a time, with race attrition, the 1.1-litre MG of John Ford was running second overall, until a three-car pile-up at Maison Blanche took it out of the race. The Aston Martin challenge collapsed in a disastrous two laps that saw three of their works cars retire. This left the Riley works team to finish second, third, fifth and sixth and claim both the Index of Performance and Biennial Cup.

Chinetti and Étancelin held on to win comfortably overall, with the second-biggest winning margin to date, of 180 km (110 mi), albeit the shortest overall winning distance of the decade.
