(詳細はGeneral Motors G platform (also called G-body) was an automobile platform designation used for mid-sized rear wheel drive cars first from 1969-1972 and again from 1982 to 1988. The G-body models began production designated as A-body cars in 1978, but were redesignated as G when the new front wheel drive A-body was introduced in 1982 The G-body designation was originally used for 1969–1972 Pontiac Grand Prix and 1970–1972 Chevrolet Monte Carlo personal luxury coupes. Between 1973 and 1981 the A-body coupes with formal rooflines were designated as ''A-Special'' and after 1982 dubbed as the ''G-Special''. These special coupes included Monte Carlo, Grand Prix, Oldsmobile Cutlass Supreme and Buick Regal two door models. The 1978 model year being the changeover year between the larger 73-77 body style and the reborn A/G platform. The Cutlass Supreme chassis being named an A body until GM changed the name into the official G body platform even though they were near identical, in 1981. At some point in the platform's lifetime, the term "G-Body Shuffle" became popular in the drag racing community (where the cars were often modified for racing) for the vehicle's side-to-side motion of the rear end after taking off from the starting line. This was due to the car's triangulated four-link rear end suspension, which caused uneven torque to the rear wheels under strenuous driving. In 1982, the Chevy Malibu/Pontiac LeMans coupes were dropped along with the Buick/Olds fastbacks. 1983 was the last year for wagons and Chevy Malibu sedans, leaving the G-Special coupes, B-O-P formal-roof sedans and the Chevy El Camino/GMC Caballero. In 1988, most remaining G-body models were moved to the new front wheel drive GM W platform, although the Pontiac Bonneville moved to the H-body, the El Camino was dropped without replacement and there would be a one-year gap before the W-body Chevy Lumina coupe truly replaced the Monte Carlo. GM later used the GM G platform (FWD) designation for unrelated full-sized cars. G-bodies were some of the last cars to follow the classic muscle car formula, remaining popular while most mid-sized cars moved to front wheel drive. They were also raced in NASCAR. ==Vehicles== This family consisted of: * Buick Regal (1978–1987) * Chevrolet El Camino (1978–1987) * Chevrolet Malibu (1978–1983) * Chevrolet Monte Carlo (1978–1988) * GMC Caballero (1982–1987) * Oldsmobile Cutlass Supreme (1978–1988) note: 1988 model known as Cutlass Supreme Classic * Oldsmobile Cutlass Cruiser (1982–1983) * Oldsmobile Cutlass Salon (1986–1987) * Pontiac Bonneville (1982–1986) * Pontiac Grand Prix (1978–1987) 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 G platform (1969)」の詳細全文を読む スポンサード リンク
