1970 Pontiac Firebird Formula 400 Series (Best)
The Pontiac Firebird Formula 400 Series was the Firebird model that broke the mold. Pontiac positioned the Firebird above the Camaro in terms of refinement and performance. The 400 Series took the performance to the next level with a car cut for the track. A low-slung exterior only amplified the performance-oriented look and feel of the car (via Classic Car Database).
The 1970 Firebird also introduced the world to the next generation of the GM F-Body car. The styling was radically different than the outgoing generation. GM intended to take Ford head-on with the new design of the car and it proved popular. The Firebird’s design would stay the same until the third generation car was introduced in the 1980s.
