The Pontiac LeMans was a model name that was applied to subcompact- and intermediate-sized automobiles marketed by Pontiac from 1962 to 1981. Manufactured in five generations in the 1960s and '70s, it was replaced by the downsized Pontiac Bonneville for the 1982 model year. Originally a trim upgrade based on the Tempest, it spawned the industry changing signature muscle car, the Pontiac GTO, in 1964.
