The first Firebird was based on Chevrolet Camaro. It has shared its body styling. Unlike the Camaro, the Firebird's bumpers were integrated into the design of the front end. Also, the taillights were different. They were inspired by the 1966 Pontiac GTO. Both a two-door hardtop and a convertible were offered through the 1969 model year. Originally, the car was a "consolation prize" for Pontiac, which had desired to produce a two-seat sports car based on its original Banshee concept car. However, GM feared this would cut into Chevrolet Corvette sales, and gave Pontiac a piece of the "pony car" market through sharing the F-body platform with Chevrolet.



The 1967 base model Firebird came equipped with the Chevrolet 230 cu in (3.8 L) SOHC inline-six. Fitted with a single-barrel carburetor, it was rated at 165 hp (123 kW). The "Sprint" model six came with a four-barrel carburetor, developing 215 hp (160 kW). Most buyers opted for one of three V8s: the 326 cu in (5.3 L) with a two-barrel carburetor producing 250 hp (190 kW); the four-barrel "HO" (high output) 326, producing 285 hp (213 kW); or the 325 hp (242 kW) 400 cu in (6.6 L) from the GTO.



The styling difference from the 1967 to the 1968 model was the addition of federally-mandated side marker lights: for the front of the car, the turn signals were made larger and extended to wrap around the front edges of the car, and on the rear, the Pontiac (V-shaped) Arrowhead logo was added to each side. The front door vent-windows were replaced with a single pane of glass and Astro Ventilation, a fresh-air-inlet system. The 1969 model received a major facelift with a new front end design but unlike the GTO, it did not have the Endura bumper. The instrument panel and steering wheel were revised. The ignition switch was moved from the dashboard to the steering column with the introduction of GM's new locking ignition switch/steering wheel.
