1975 FIREBIRD

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.
