Post-war, the Delage company prospered, producing high quality, well-engineered touring and luxury saloon cars. In motor racing, Great Britain's Dick Seaman and female driver Kay Petre gained fame in their Delage racecars while France's Robert Benoist and René Thomas were among the leading drivers of their day. In 1914, Thomas traveled to the United States and drove a Delage to victory at the Indianapolis 500 and in 1914, he set a new land speed record at just over 143 mph (230 km/h). The first ever British Grand Prix, held in 1926, was won by the French team of Louis Wagner and Robert Sénéchal driving a Delage 155B. Throughout the mid 1920s, Delage vehicles dominated racing, with Benoist winning the British, French, Spanish and Italian Grand Prix races.

However, the Great Depression of the 1930s took its toll and in 1935 the company went into voluntary liquidation. The Delage plant in Courbevoie was closed and its contents sold. A license to manufacture cars under the Delage name was negotiated with the Delahaye automobile company who continued to produce a Delage model until it went out of business in 1953.
