In 1920, after various kingds of difficulties, it merged with Clement-Talbot, and Darracq, and the consortium became known as S.T.D. (Sunbeam, Talbot, Darracq). In 1923 Coatalen was replaced by an Italina, Vincenzo Bertarione, who designed an engine with double overhead camshaft and spherical main bearings. The technical similarities between this and Fiat’s current racing model (Bertarione had come from Fiat) prompted the suspicion that it had been taken straight from the Italian 804-404, which had been designed for the new formula imposed in 1922. In 1923 Segrave won imposed in 1922. In 1923 Sevrave won the French Grand Prix in a car designed by Bertarione.
In 1935 S.T.D. was absorbed into Rootes, and Sunbeam ceased production. In 1938 the name was revived in a new firm created by Rootes called Sunbeam-Talbot Ltd. Later Rootes cars with particularly high performance were given the name Sunbeam. In 1975 Chrysler, which had bought Rootes, abolished the name, only reinstating it in 1977.
