The Fourth Generation F-body continued the aerodynamic formula initiated by the previous generation, but while still a desirable sports car, it fell victim to 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. (more…)

1989GM made a new dual catalytic converter exhaust system (RPO code N10) available, freeing up 13% more power from some LB9- and L98-equipped Formulas and Trans Ams; so equipped, LB9 engine output was increased to 230 hp while the L98 increased to 240 hp.   (more…)

1985All Firebird models underwent redevelopment to boost sales as a number of power train improvements were introduced. The LB9 Tuned Port Injection (TPI) 305 was released, replacing the 305 H.O. as the high-output engine: using a tuned runner design, the LB9 produced 215 hp, which brought it suitable attention from buyers despite being unavailable with a manual transmission. The carbureted V6 was replaced with a new, multi-port fuel-injected 2.8L V6 making 135 hp. A Borg-Warner 9-bolt differential was made available for the first time, and the new positive traction rear end was said to be stronger than the Dana 44. (more…)

The Third Generation F-body weighed in quite a bit lighter than its predecessor and offered sleek, aerodynamic styling that was particularly reflected by the Firebird. GM's CCC (Computer Command Control) engine control system also continued to evolve, simultaneously increasing engine performance, raising fuel economy, and lowering emissions. This combination of factors helped the Third Generation Firebird to re-energize its fading pony car image. (more…)

The Second Generation appeared for the 1970 model year as a mid-year introduction on February 26, 1970 — but was officially designated by Pontiac as a 1970 model, not a 1970-1/2 as many sources have reported through the years. Replacing the "Coke bottle" styling was a more "swoopy" body style, with the top of the rear window line going almost straight down to the lip of the trunk lid — a look that was to epitomize F-body styling for the longest period during the Firebird's lifetime. The new design was initially characterized with a large C-pillar, until 1975 when the rear window was enlarged. There were two Ram Air 400 engines for 1970: the Ram Air III (335 hp, 366 hp in GTO) and the Ram Air IV (345 hp, 370 hp in GTO) which were carried over from 1969. A...

The Pontiac Firebird was a sports/muscle car built by the Pontiac division of General Motors between 1967 and 2002.The Firebird was introduced in the same year with its platform sharing cousin the Chevrolet Camaro. This coincided with the release of the Mercury Cougar, which shared its platform with another well-known pony car, the Ford Mustang. The vehicles were, for the most part, powered by various V8 motors 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 all Pontiac motors were dropped in favor of corporate motors.

The Pontiac Trans Am was an automobile produced by Pontiac, a division of General Motors (GM), to appeal to the growing muscle car population. Four distinct generations, based on Pontiac Firebird coupe body styles were produced between 1967 and 2002. These cars were built on the F-body platform, which was also shared by the Chevrolet Camaro. (more…)
