Founded in 1905 by Louis Delage Rue Cormeilles in Levallois-Perret, the company was initially just an assembly plant, buying engines and chassis to other manufacturers for the dress body parts. The first model is a Delage Type A motor-cylinder De Dion Bouton 9 ch. In 1907 the factory moved to rue Baudin Levallois always to grow with 4 000 m2 workshop. Delage won that year the 'Grand Prix of France' at Dieppe 500 km to 80 km / h average.
