The Grand Prix was a one-of-a-kind automobile; the vehicle was offered in only one body style – the 2-door hardtop with 5-passenger seating. The Grand Prix was aimed at customers seeking luxury with sports car styling. The 1966 Pontiac model was cleaner looking and was sporting new frenched headlights and blacked out egg-crate grille with inset rectangular parking lamps (a style that would appear the next year on the GTO). Other features included the tail light panels with chrome trim ribs, GP identification on the front fenders, and rear fender skirts. Inside the vehicle, the buyer would find Strato Bucket Seats and a stunning instrument panel covered in mahogany wood grain accented with rectangular instruments. The engine offered was the 389 cid at either 325 or 333 hp depending on carburetion and transmission configuration.

The 1965 and 1966 Pontiacs were successful years for the Pontiac Motor Division; in those years, sales were fast-paced and there were numerous models. Up the line for the 1966 Pontiacs was the Star Chief Executive, Bonneville, and the Grand Prix. The senior series had power that ranged from the 389 cid V8 at 260 hp to the full-muscled 421 cid V8 at 376 hp.

The mid-sized Tempest line was offered in four models: the Tempest, Tempest Custom, Lemans, and the Tempest GTO. A full range of styles were available, such as the pillared sport coupe, hardtop coupe, a four-door hardtop and sedan, convertible, and wagon. Engines ranged from the 236 cid 6 cyl @ 165 hp to the 389 cid V8 @ 360 hp available in the GTO.
