The Pontiac Le Mans was first seen in 1962 as the top of the line option on the Pontiac Tempest and offered a sportier and more deluxe trim and interior and included bucket seats. In 1964 the Tempest Le Mans was restyled and upsized to an intermediate-sized car, rather then the previous compact that it had been. Also offered on the '64 Le Mans was the GTO ( Gran Turismo Omologato), and included a larger 389 V8 with 325 or 348 hp, a three-speed floor shift manual transmission with Hurst shifter, heavy-duty suspension, red-line Tiger Paw tires and GTO nameplates. Sales of this popular model soared and in 1966 the GTO became a separate model of it's own. The Le Mans contnued as the top of the line, on the Tempest series and in 1970 Pontiac reshuffled its intermediate lineup
and the LeMans nameplate was downgraded to the mid-line subseries previously known as the Tempest Custom.
1981 was the last year for the Le Mans, as it was replaced by the longer lasting Bonneville.
