In 1925, 49 cars lined up on the starting grid, including Bentley (with 1924’s winning pair, Duff and Clement), Chenard & Walcker (the 1923 victors), Lorraine, Austin, Sunbeam, Chrysler, Diatto and OM.
La Lorraine-Dietrich arrived with three of their B3-6 cars. The cars had been lightened, and the troublesome steel “artillery” wheels were replaced by Rudge-Whitworth wire ones. All three cars were now on Englebert tyres. Driver pairings were: Gérard de Courcelles and André Rossignol; Edouard Brisson and Henri Stalter; and Robert Bloch with the new Léon Saint-Paul.
The Chenard & Walcker took the lead but later encountered problems of its own. This is when the two Lorraine Dietrich launched their attack. They went out in front and managed to stay there until the end of the race.
In 1925 the cars started first time with now famous Le Mans-style start , and a requirement for cars to start the race with the soft-top in place and keep it there the first 20 laps. The first fatal accidents happened in 1925: André Guilbert driving Ravel Type A Sport (12CV) was killed in the practice sessions, and Marius Mestivier in Amilcar CGS fatally crashed soon after the start of the race.
