(詳細はautomobile platform used by General Motors from 1981 to 2005. Marking the transition to front-wheel drive in the compact-car segment in North America, the J platform was the successor to H platform, making it the third generation of compact cars designed by the company. Outside of North America, the J platform was adopted as a mid-size car as GM-controlled converted to front-wheel drive. By 1990 in North America, the J-platform began to be phased out in North America as several divisions (Buick, Oldsmobile, and Cadillac) exited the compact segment. In the 1990s, as GM modernized its global offerings, the J-platform was phased out outside of North America and replaced by cars based on the GM2900 platform. Following several redesigns, the most popular variants (the Chevrolet Cavalier and Pontiac Sunfire) remained in production into the early 2000s. For 2005, the J-platform was phased out entirely as the Chevrolet Cavalier was replaced by the Chevrolet Cobalt on the Delta platform; the final J-platform vehicles were Pontiac Sunfires, which ended production in June 2005. == Background == Design of the J-body dated back to the mid-1970s. At that time, GM-controlled divisions in different parts of the world manufactured totally different rear-wheel drive C-segment cars - the Chevrolet Vega in America, the Vauxhall Cavalier/Opel Ascona in Europe, the Holden Torana in Australia and the Isuzu Florian in Japan. Due to the exterior dimensions, and engines offered were found to be in compliance with Japanese regulations, the platform was classed in the favorable "compact" designation, and competed with other Japanese made products sold in Japan at the time. Isuzu also supplied kits for Holden's J-car version, the Camira. It was decided that a common replacement would be developed to eliminate duplication of engineering effort and ensure parts interchangeability — a practice known as badge engineering. When the Arab Oil Embargo forced CAFE mandates, and the fear of US$3.00 for a gallon of gasoline, the J-body was practically produced straight off the drawing board. In continental Europe, the car was sold as the Opel Ascona. In Britain, it was sold as the Vauxhall Cavalier. No matter which badging they carried, European production occurred in plants in Germany, Belgium, and Britain. It was generally well received but was narrowly beaten to the European Car of the Year accolade by the Renault 9. At the time, it set new standards for performance and economy in this size of car in Europe; for instance, the 1.6 petrol engined Cavalier for the British market had a top speed of 105 mph, compared to the 101 mph top speed of the 2.0 petrol engined Ford Cortina - its key competitor.〔 The fourth character in the Vehicle Identification Number for a J-body car is "J". 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「GM J platform」の詳細全文を読む スポンサード リンク
