Delage was another famous French car company with a strong pre-war motor-racing pedigree already, including winning the 1914 Indianapolis 500, and quickly resumed racing after the war with its big 5- and 6-litre racing cars. The DE raced at Le Mans was a 1-off special of the current popular production model fitted with its engine modified to carry an overhead-valve cylinder head. It was raced by new works driver Paul Torchy and test driver Belbeu.
