GM J-Body Cars
Overview
The GM J-body is a compact car platform that was produced by General Motors from 1981 to 2005. It was the successor to the GM H-body platform, and it was used for a variety of vehicles, including the Chevrolet Cavalier, Pontiac Sunbird, Oldsmobile Firenza, and Buick Skyhawk. The J-body was also used for the Saturn SL and Saturn SC coupes.
The J-body was a front-wheel drive platform, and it was designed to be lightweight and fuel-efficient. It was also designed to be easy to manufacture, and it was one of the first GM platforms to use computer-aided design and manufacturing (CAD/CAM). The J-body was a very successful platform for GM, and it was produced for over 20 years.
History
The J-body was developed in the late 1970s as a replacement for the GM H-body platform. The H-body was a rear-wheel drive platform that was used for a variety of vehicles, including the Chevrolet Chevette, Pontiac Sunbird, Oldsmobile Starfire, and Buick Skyhawk. The H-body was a very successful platform for GM, but it was starting to show its age by the late 1970s. It was also not very fuel-efficient, and it was not well-suited for front-wheel drive.
GM began development of the J-body in 1978. The J-body was designed to be a lightweight, fuel-efficient, and easy-to-manufacture platform. It was also designed to be front-wheel drive. The J-body was the first GM platform to use CAD/CAM, and it was one of the first GM platforms to be designed using computer simulations. The J-body was also the first GM platform to use a transverse engine mount, which allowed for a more compact and efficient engine compartment.
The J-body was introduced in 1981 with the Chevrolet Cavalier and Pontiac Sunbird. The Oldsmobile Firenza and Buick Skyhawk followed in 1982. The J-body was a very successful platform for GM, and it was produced for over 20 years. The J-body was used for a variety of vehicles, including the Chevrolet Cavalier, Pontiac Sunbird, Oldsmobile Firenza, Buick Skyhawk, Saturn SL, and Saturn SC coupes.
Design

It was also designed to be easy to manufacture, and it was one of the first GM platforms to use CAD/CAM. The J-body was a very successful platform for GM, and it was produced for over 20 years.
The J-body was a very compact platform, and it was designed to be as lightweight as possible. The J-body used a unibody construction, and it was made of lightweight materials, such as aluminum and plastic. The J-body was also designed to be aerodynamic, and it had a low coefficient of drag. The J-body was a very fuel-efficient platform, and it was one of the first GM platforms to meet the CAFE standards.
The J-body was also designed to be easy to manufacture. The J-body used a modular design, and it was designed to be easy to assemble. The J-body was also designed to be easy to service, and it had a number of features that made it easy for technicians to access the engine and other components.
Legacy
The J-body was a very successful platform for GM, and it was produced for over 20 years. The J-body was used for a variety of vehicles, including the Chevrolet Cavalier, Pontiac Sunbird, Oldsmobile Firenza, Buick Skyhawk, Saturn SL, and Saturn SC coupes.
