Rootes Group

STD Motors went bankrupt in 1934 at the height of the Great Depression. By this point only Talbots was still a success, and in 1935 that portion was purchased by the Rootes Group. The receivers eventually sold the rest of the company to William Lyons of "SS Cars," who was looking for a name change given the rising Nazi connotations. But just as the deal was supposed to close, Rootes purchased Sunbeam out from under Lyons, who was justifiably upset. He then changed the name of SS Cars to Jaguar.
Rootes was an early proponent of badge engineering, building a single mass-produced chassis and equipping it with different body panels and interiors to fit different markets. He ended production of existing models at all the new companies, replacing them with designs from Hillman and Humber that were more amenable to mass production. For many years the "Sunbeam-Talbot" marque was used on their upscale versions, while Hillman was use on base models and Humber on trucks.
In 1935 the Rootes Group headed by brothers, William "Billy" and Reginald, bought the bankrupt Sunbeam and Talbot marques and quickly moved to introduce a new marque in 1938 called Sunbeam-Talbot which combined the quality Talbot coachwork and the current Hillman and Humber chassis and was assembled at the Talbot factory in London. The initial two models were the Sunbeam-Talbot 10 and the 3-litre followed by the Sunbeam-Talbot 2 litre and 4 litre models based on the earlier models only with different engines and longer wheelbases. Production of these models continued after the war until 1948.
In the summer of 1948, the Sunbeam-Talbot 80 and Sunbeam-Talbot 90 were introduced, with a totally new streamlined design with flowing front fenders (wings). The 80 used the Hillman Minx based engine with ohv and the 90 utilized a modified version of the Humber Hawk with ohv. The car bodies were manufactured by another Rootes Group company, British & Light Steel Pressings however the convertible drophead coupe shells were completed by Thrupp & Maberly coachbuilders in Cricklewood. The underpowered 80 was discontinued in 1950. The 90 was renamed the 90 MK II and then the 90 MK IIA and eventually in 1954 the Sunbeam MK III, finally dropping the Talbot name. With the model name changes, the headlights were raised on the front fenders and an independent coil front suspension and the engine displacement went from 1944cc to 2267cc with a high compression head and developing 80 bhp.
There was one more model of the Sunbeam-Talbot that appeared in 1953 in the form of an Alpine, a two seater sports roadster which was initially developed by a Sunbeam-Talbot dealer George Hartwell in Bournemouth as a one-off rally car that had its beginnings as a 1952 drophead coupe. It was named supposedly by Norman Garrad, (works Competition Department) who was heavily involved in the Sunbeam-Talbot successes in the Alpine Rally in the early 1950's using the Saloon model. The Alpine Mk I and Mk III (a Mk II was never made) were hand built like the Drophead Coupe at Thrupp & Maberly coachbuilders from 1953 to 1955 when production ceased after close to 3000 were produced. It has been estimated that perhaps only 200 remain in existence today. The Talbot name was dropped in 1954 for the Sunbeam Alpine sports car, making Sunbeam the sports-performance marque. In 1955 a Sunbeam saloon won the Monte Carlo Rally. Production ceased in 1956 and replaced by the sporty Sunbeam Rapier.
In 1959 a totally new Alpine was introduced, and the 1955 Rapier (essentially a badge-engineered Hillman Minx) was upgraded. After several successful series of the Alpine were released, director of US West-Coast operations, Ian Garrad, became interested in the success of the AC Cobra, which mounted a small-block V-8 engine in the small AC Ace frame to create one of the most successful sports cars of all time. Garrad became convinced the Alpine frame could also be adapted the same way, and contracted Carroll Shelby to prototype such a fit with a Ford engine. The result was the Sunbeam Tiger, released in 1964, which went on to be a huge success.
