The General Motors J platform, or J-body, is an automobile platform that was used by General Motors for compact cars from the 1982 to 2005 model years. The third generation of compact cars designed by GM, the J-body marked the introduction of front-wheel drive for its compact model lines, simultaneously replacing the rear-wheel drive H-body and the European U-body platforms, the latter being a stretched version of the original rear-wheel drive T-body. The J-body was marketed as a world car, with GM brands selling versions of the platform in North America, Europe, Australia, and Japan; in markets outside of North America, the model line was packaged as a mid-size car.
Outside North America, the use of the J platform was phased out after the 1980s in favor of the Opel-based GM2900 platform. In North America, the introduction of the Saturn S-Series would lead to the consolidation of the J-body to the Chevrolet and Pontiac brands.
Following several major revisions, the J platform remained in use into the 21st century; in June 2005, the final example (a Pontiac Sunfire) was produced. Introduced by Saturn for 2003, the GM Delta platform is the fourth generation of compact cars from General Motors.
