Pontiac Tempest Le Mans/GTO
From 1962 to 1981 the Pontiac division of General Motors produced solid, intermediate-sized automobiles called the Pontiac LeMans. Then in 1982 the smaller Pontiac Bonneville model replaced the LeMans.
The LeMans was introduced as the top-line version of the smaller and more solid Pontiac Tempest and had more luxurious trimmings and a sportier look than the Tempest. In 1964 when the Tempest was restyled and enlarged in the form of the LeMans, it continued to have the same 326 cubic inch V8s and 215 cubic inch six-cylinder found in the regular Tempest.
Not long after the 1964 model was produced, the LeMans came out with an alternative performance package assigned as the GTO or the Gran Turismo Omologate. This version came with a lot of technical developments and upgrades, costing just under US$300. It was estimated that 5,000 GTOs would be sold that year but the sales ended up being 32,000, thereby accounting for a substantial portion of the Tempest and LeMans sales.
In 1996 the GTO was made separate from the other models, having the basic shape of the LeMans and Tempest models. The GTO kept the big-engined muscle car style where as the Tempest and the LeMans models received a new SOHC 230 cubic inch six-cylinder engine.
During the late 1960′s the Sprint-optioned LeMans and Tempest models were not as popular as the larger-engined GTO that was fueling the muscle car wars. Those that bought the normal regular LeMans and Tempest models mostly ordered V8 power, as the 326 and the later 350 cubic inch V8 version were the most ordered engines. In 1969 the SOHC six-cylinder engine and the Sprint option were stopped and replaced by an ordinary Chevrolet-built 250 cubic inch OHV six-cylinder engine, which became the base engine in most of the Pontiac intermediates.
When the LeMans was first produced it included a convertible and a pillared coupe with no hardtop option offered in the Tempest. Then in 1964 the hardtop coupe was added followed by the four-door pillared sedan a year later. In 1966 and 1968 the four-door hardtop and then a four-door Safari wagon replaced the previous versions. Over the decades the Pontiac continued to change its style, adding many amazing features and continued to be popular cars.
