36: Pontiac Firebird Formula 400 Ws6
Although we included the Firebird on this list already it’s important to note a special edition of the car that came in 1977. The muscle car era was long over by this period of time but GM still wanted to give it a final whirl. The Firebird always had trouble differentiating itself from the Camaro corporate siblings. Nevertheless, the Pontiac Firebird Formula 400 Ws6 came with an immense amount of hype surrounding it.
While it’s true that the performance was much improved over the regular Firebird models, it didn’t add up to the hype. There was already a declining market for these types of cars and the new addition to the Firebird lineup didn’t make much difference. The Pontiac Firebird Formula 400 Ws6 failed to meet the high expectations GM set for it.
