Pontiac Firebird

The Pontiac Firebird was built by the Pontiac division of General Motors between 1967 and 2002. The Firebird was introduced the same year as the automaker's platform sharing model, the Chevrolet Camaro. This coincided with the release of the 1968 Mercury Cougar, which shared its platform with another pony car, the Ford Mustang. The vehicles were powered by various four cylinder, six cylinder, and V8 engines of different GM divisions. While primarily Pontiac powered until 1977, Firebirds were built with several different engines from nearly every GM division until 1982 when GM began to discontinue engines it felt were unneeded and either spread successful designs from individual divisions among all divisions or use new engines of corporate architecture.

The Trans Am was a specialty package for the Firebird, typically upgrading handling, suspension, and horsepower, as well as minor appearance modifications such as exclusive hoods, spoilers, fog lights and wheels. Four distinct generations were produced between 1969 and 2002. These cars were built on the F-body platform, which was also shared by the Chevrolet Camaro. The second generation was available from 1970 to 1981 and was featured in the 1977 movie Smokey and the Bandit, the 1978 movie Hooper and the 1980 movie Smokey and the Bandit II. The third generation, available from 1982 to 1992, was featured in the 1983 movie Smokey and the Bandit Part 3 and the 1984 movie Alphabet City. KITT, the automotive star, and its evil counterpart KARR, of the popular 1980s TV series Knight Rider, was a modified third generation Trans Am.

The first generation Firebirds had a characteristic Coke bottle styling. Unlike its cousin, the Chevrolet Camaro, its bumpers were integrated into the design of the front end and its rear slit taillights were inspired by the Pontiac GTO. Both a two door hardtop and a convertible were offered through the 1969 model year. Originally the car was a consolation prize for Pontiac, who had initially wished to produce a two seat sports car of its own design, based on the original Banshee concept car. However, GM feared such a vehicle would directly compete with Chevrolet's Corvette, and the decision was made to give Pontiac a piece of the pony car market by having them share the F-body platform with Chevrolet.

A distinctive, slant nose facelift occurred in 1977, redone somewhat in 1979. From 1977 to 1981, the Firebird used four square headlamps, while the Camaro continued to retain the two round headlights that had previously been shared by both Second Generation designs. The 455 engine available in the second generation Firebird Trans Am was arguably the last high-performance engine of the original muscle car generation. The 455 cu in (7.5 L) engine first made its appearance in 1971 as the 455 HO. In 1973 and 1974, a special version of the 455, called the SD-455, was offered.

The availability and cost of gasoline (two fuel crises had occurred by this time) meant the weight and the fuel consumption of the 3rd generation had to be considered in the design. In F-body development, both the third generation Firebird and Camaro were proposed as possible front wheel drive platforms, but the idea was scrapped. The state of the art of computerized engine management was in its infancy, and as long as saving fuel was the primary objective, it was not possible to have high horsepower and torque numbers. They did manage to cut enough weight from the design so that acceleration performance would be better than the 1981 models. GM executives decided that engineering effort would best be spent on aerodynamics and chassis development. Little did they know that by 1989 the fastest American car on the market would be a Firebird.

The fourth generation F-body continued the aerodynamic formula initiated by the previous generation, but saw declining sales. As before, the Camaro kept the exposed headlights and the Firebird its pop up units, with some minor changes. The overall styling of the Firebird more strongly reflected the Banshee IV concept car than the 1991 face lift received by the Third Generation model.
