Sunbeam was a marque registered by John Marston Co. Ltd of Wolverhampton, England in 1888. The company first made bicycles, then motorcycles and cars, from the late 19th century until about 1936, and applied the marque to all three forms of transportation. The company also manufactured aero engines in World War I and 647 aircraft during World War II. Sunbeam cars set a number of land speed records, and a Sunbeam was the first British car to win a Grand Prix race. The company went into receivership in 1935 and was purchased by the Rootes Group, which continued to use the Sunbeam marque until 1976 when new owners Chrysler rebranded the vehicles. ==Early history== John Marston was apprenticed to the Jeddo Works of Wolverhampton as a japanner (metal lacquerer). In 1859, at the age of 23, he bought two tinplate manufacturers and set up on his own as John Marston Co. Ltd. Marston was an avid cyclist; and, in 1877, he set up the Sunbeamland Cycle Factory, producing bikes known as Sunbeams. Between 1899 and 1901, the company also produced a number of experimental cars, but none was offered to the market. The first production car named as a Sunbeam was introduced in 1901, after a partnership with Maxwell Maberley-Smith. The Sunbeam-Mabley design was an odd one, with seats on either side of a belt-drive powered by a single-cylinder engine of less than . The design was a limited success, with 420 sold at £130 when production ended in 1904 (source?? Other sources state 130 made). At that point the company started production of a Thomas Pullinger–designed car based on the Berliet mechanicals. They introduced a new model, based on a Peugeot motor they bought for study, in 1906 and sold about 10 a week. In 1905, the Sunbeam Motorcar Company Ltd was formed separate from the rest of the John Marston business, which retained the Sunbeam motorcycles and bicycles. The Breton car designer, Louis Coatalen, joined the company from Hillman-Coatalen in 1909, and became chief designer. He soon reorganised production such that almost all parts were built by the company, as opposed to relying on outside suppliers. He quickly introduced his first design, the Sunbeam 14/20, their first to use a shaft-driven rear axle, upgrading it in 1911 with a slightly larger engine as the 16/20. Sunbeam made a small number of Veterans, and by 1912 were making conventional, high-quality cars. Direct competitors to Rolls Royce, Sunbeams were considered to be a car for those who thought an RR a little ostentatious. Coatalen was particularly fond of racing as a way to drive excellence within the company, noting that "Racing improves the breed". After designing the 14/20, he started the design of advanced high-power engines, combining overhead valves with a pressurised oil lubrication system. In 1910 he built his first dedicated land-speed-record car, the Sunbeam Nautilus, powered by a 4.2-litre version of this engine design. The Nautilus implemented a number of early streamlining features, known as "wind cutting" at the time, but the custom engine suffered various problems and the design was eventually abandoned. The next year he introduced the Sunbeam Toodles II, featuring an improved valve system that turned it into a success. Coatalen won 22 prizes in Toodles II at Brooklands in 1911, and also achieved a flying mile of to take the 16 hp Short Record. Sunbeam cars powered by more conventional (for the time) side-valve engines featured prominently in the 1911 Coupé de l'Auto race, and improved versions won first, second and third the next year. Sunbeams continued to race over the next few years, but the company had moved on to other interests. Coatalen also designed a number of passenger cars, notably the Sunbeam 12/16. By 1911 Sunbeam were building about 650 cars a year, at that time making them a major manufacturer. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sunbeam (car company)」の詳細全文を読む スポンサード リンク
