The MGB is a two-door sports car manufactured and marketed by the British Motor Corporation (BMC), later British Leyland, as a four-cylinder, soft-top roadster from 1962 until 1980. Variants include the MGB GT three-door 2+2 coupé (1965–80), the six-cylinder roadster and coupé MGC (1967–69), and the eight-cylinder 2+2 coupé, the MGB GT V8 (1973–76). Replacing the MGA in 1962, production of the MGB and its variants continued until 1980, achieving sales for the MGB, MGC and MGB GT V8 combined of 523,836 cars. The MGB bodyshell was reprised in modified form with a limited run of 2,000 MG RV8 roadsters (1993–95). == History == In structure the MGB was an innovative, modern design in 1962, utilizing a monocoque structure instead of the traditional body-on-frame construction used on both the MGA and MG T-types and the MGB's rival, the Triumph TR series. However components such as brakes and suspension were developments of the earlier 1955 MGA with the B-Series engine having its origins in 1947. The lightweight design reduced manufacturing costs while adding to overall vehicle strength. Wind-up windows were standard, and a comfortable driver's compartment offered plenty of legroom. A parcel shelf was fitted behind the seats. The MGB achieved a 0–60 mph (96 km/h) time of just over 11 seconds. The 3-bearing 1798 cc B-Series engine produced 95 hp (71 kW) at 5,400 rpm — upgraded in October 1964 to a five-bearing crankshaft. The majority of MGBs were exported to the United States. In 1975 US-market MGB engines were de-tuned to meet emission standards, ride height was increased by an inch (25 mm), and distinctive rubber bumpers were fitted to meet bumper standards. The MGB was one of the first cars to feature controlled crumple zones designed to protect the driver and passenger in a 30 mph (48 km/h) impact with an immovable barrier (200 ton).〔(【引用サイトリンク】 publisher = Conceptcarz.com )〕〔(【引用サイトリンク】title=1967 MGB 30mph frontal impact into a concrete block, Abingdon in 1967 (scroll down) )〕 A limited production of 2,000 units of the RV8 was produced by Rover in the 1990s. Despite the similarity in appearance to the roadster, the RV8 had less than 5 percent parts interchangeability with the original car. 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「MG MGB」の詳細全文を読む スポンサード リンク
