The General Motors L platform (commonly called the L-body or L car) was a front-wheel-drive compact car automotive platform that was produced from 1987 through 1996.
The L platform was very similar to the GM N platform; however, the first-generation N-cars were engineered by Oldsmobile, while the L-cars were engineered by Chevrolet. The L platform used a twist-beam rear suspension and MacPherson struts in the front and featured a 103.4inches wheelbase. Both platforms were used to replace the GM X platform on which the Citation, among others, were based. GM also used a different L platform for the all-wheel-drive versions of the Chevrolet Astro/GMC Safari mid-size vans.
Pontiac sold its own version of the L-body in Canada only. It was marketed as the Tempest from 1987 to 1991. This model featured a unique grill and tail lamps (which were later used on the updated Corsica). This model was dropped after 1991, being replaced by the new 1992 Grand Am sedan.
The L-car lasted just one generation, with the nameplates being retired and replaced by the N-body Chevrolet Malibu.
This platform was the basis for the following vehicles:
