Pionneers and dust, then 8 cylindres in row domination
The Bentley Boys gain the upper hand over Chenard & Walcker on a 17.262, then 16.340km long and non-tarred track. Passed twice by Lorraine Dietrich, the English keep the supremacy anyway thanks to a capacity increasing, over the years, from 3 to 6.5 litres.
In 1931 on a circuit passing to 13,492 km, the super-charged 2.3 litre Alfa Romeos continue where Bentley left off. Then, Bugatti was next to dominate twice, leaving a single victory for Lagonda and Delahaye.
With 58 cars on the 1935 starting grid a new participation record is broken.
In 1940 motor sports are not a priority. The cannons are rumbling and for 10 years there will be no 24 Hours of Le Mans or any other event.
