Four models were offered: base, Esprit, Formula, and Trans Am
New front-end styling for the Firebird coupe featured quad rectangular headlamps and an aggressive grille.
Four models were offered: base, Esprit, Formula, and Trans Am
Formula's new hood had simulated air scoops and at its rear end was a spoiler
The wheelbase was 108 in.
The inline six-cylinder base engine was replaced with a 231-cid (3.8-liter) V6
A 301-cid and 305-cid engine were introduced
The 403-cid (6.6-liter) V-8 was the largest engine
Firebird's new grille was deeply recessed, directly in line with the quad rectangular headlamps
Its simple pattern consisted of a series of round-like (hexagonal) holes, resembling fencing more than a customary grille.
A "Pontiac" nameplate went on the driver's side of the grille
Crossbar trimmed amber park/signal lamps were also recessed, but into the outer ends of twin air intake slots below the bumper strip.
The center front panel protruded forward to a slight point and contained the usual Pontiac emblem, but its sides were more sharply angled than the 1976 version
Esprit could have a new blue "SkyBird" appearance package with blue velour seating, two-tone blue body and blue cast aluminum wheels.
Firebird Formula came with a new 301-cid (5.0-liter) two-barrel V-8.
Its body displayed blacked-out trim, dual hood scoops, and large "Formula" graphics on the lower door.
The Trans Am had a new shaker hood and came with a standard 400-cid or 403-cid V-8.
Also available was an optional "T/A 6.6" power plant.

HISTORICAL NOTES

Introduced Sept. 30, 1976
Alex C. Mair was Pontiac's general manager
High sales of the Trans Am of 1977-79 was certainly due to the 1977 movie Smokey and the Bandit starring Burt Reynolds, Sally Fields, and Jackie Gleason. It was a cops-and-robbers chase spectacular. The "bandit" was the unstoppable black Trans Am.
