Pontiac Firebird (third Generation) - 1988

1988

The Firebird remained basically unchanged. The 170 hp LG4 carbureted 5.0L V8 was dropped in favor of the new 170 hp L03 5.0L V8 with throttle body injection. All V8's engines received serpentine belt systems and the A/C compressors were moved to the passenger's side of the engine, de-cluttering the engine compartment. The Firebird Formula received new high tech 16x8-inch aluminum wheels with distinctive silver "WS6" center caps. The GTA wheels were slightly restyled, and the convex 16-inch wheels were dropped as all Trans Ams received the 16x8" diamond-spoke aluminum wheels, available in different colors (white, red, charcoal, and black) in addition to the GTA's gold. The GTA received new a steering wheel with integral radio controls. The Trans Am was made available with body-colored ground effects like those on the GTA.

The optional convertible model also carried over, and now optional on the GTA was a new "notchback" hatch: rather than the large, glass hatchback that had been common to the Third Generation Firebird, the optional notchback consisted of a fiberglass trunk lid with a small, flat, vertical glass window. The notchback also incorporated redesigned rear seatbacks with integral headrests. The notchback became popular with onlookers, who often assumed the notchback-equipped GTA was a Ferrari, thereby encouraging some owners of the type to dub their GTA the "Ferrari Back." Many Trans Am owners were unaware that the $800 notchback option was even available, and for those who were, the vehicle typically had to be ordered from the factory, on a six-month waiting list, as the notchback was retrofitted to the vehicle. In rare instances, a dealership would get a notchback-equipped GTA on their lot. Another reason for the relative obscurity of the notchback is that the sales information was not very well disseminated to Pontiac salespeople, so many of them had no idea it was available as an option. As attractive as the notchback was, GTA owners were constantly plagued with structural and cosmetic issues with the design. The fiberglass would blister, causing surface bubbles resembling a bad case of acne. The Pontiac repair solutions were simply to sand the notchback down and repaint it, but the problem would always return, and GTA owners could expect multiple trips in order to achieve a final repair of the problem, or to have a new notchback installed. The notchback was intended to carry over and be standard-issue on the 1989 20th Anniversary GTA, but the plan never materialized; the aforementioned quality control issues apparently caused GM not to carry it over to the next year..

ASC continued to offer a Convertible for dealerships in 1988. A total of 104 Firebird Convertibles are reported from ASC for Pontiac Dealerships.
