(詳細はGeneral Motors G platform (also called G-Body) automobile platform designation was used for front-wheel drive full-sized luxury cars between 1995 and 2011. Previously General Motors used the GM G platform (RWD) designation for unrelated mid-sized cars. The G-body (the GMX690) was based on Cadillac's K-body architecture. The Buick Riviera 2-door coupe moved up from the GM E platform, while the Oldsmobile Aurora 4-door sedan was a new model. ==Platform consolidation== Starting with the 1997 Buick Park Avenue, GM consolidated its four large-car platforms; C platform, K platform, H platform, and G platform; all to the G platform. However, GM decided to retain their previous platform designations. These legacy platform designations were used in the VIN number and official GM publications. Models designated as "G" went out of production for MY 1999, but successor models were sold until MY 2011. The G-body had an extremely resilient structure. For its time, the G-body was one of the strongest unibody car frames in production (25 Hz). This fact did not go untouted as GM literature made light of the need to use a 'frame crusher' designed to test heavy-duty truck frames to finally break the G-body structure in their crush-to-failure procedures. Vehicles built on the G platform are also noted for having belt-in-seat style seat belts like the mid-size GMT360 SUVs. The G-body also featured four-wheel independent suspension with a MacPherson strut style front suspension and a semi-trailing arm style rear suspension that utilized aluminum control arms. All-new aluminum control arms were introduced for the front suspension for 1998. The handling was further enhanced with standard front and rear stabilizer bars and lateral links in the rear suspension to further control wheel toe. 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 (1995)」の詳細全文を読む スポンサード リンク
