Introduced in late 1961, the Lemans was the top-of-the-line model of the first-gen Tempest. This trim package included nicer interior and bucket seats. In 1964 the Tempest was redesigned to share the intermediate A-Body platform that shared use with other GM divisions, thus shedding its compact roots as well as the quirkier engine and driveline approaches. The LeMans remained the superior option for Tempests, Pontiac also offered a higher performance more stripped-down version called the “GTO”. The idea of a smaller platform vehicle with the biggest engine you could fit became a popular option for not only other divisions within GM, but also for Ford, Chrysler, and American Motors.
