Pontiac Firebird (1975) – Ultimate Guide
Introduction
- The 1975 Firebirds looked very much the same as the 1974 models except for a new roofline with a wrap-around backlight (i.e., rear window).
- High-Efficiency ignition was added to the equipment list
- Radial-tuned suspension was added to the equipment list
- The base model had conventional wipers and minimal trim
- Esprits had concealed wipers, decor moldings, door handle inserts, and signature script on the roof pillar
- The base engine for the Esprit was the Chevy-built 105 hp 6-cyl
- Formulas featured heavy-duty chassis and distinctive twin hood scoops
- The Trans Ams had flares, spoilers, extractors, shaker hood scoop, and Firebird decals
- At the beginning of the year, the biggest engine for the Trans Am was the 400 cid V-8; but by midyear, the 455 cid V-8 was back. However, it had single exhausts and a catalytic converter. It yielded only 200 hp.
- Because the maximum horsepower dropped from 290 to 200, the M40 automatic was discontinued in favor of the M38 automatic.
