History of the 1978 Pontiac Trans Am

The second generation of the Pontiac Firebird, which includes the Trans Am, was produced from 1970 to 1981. The 1978 model year is particularly notable for the introduction of the WS6 Performance Package, which brought significant upgrades to the Trans Am’s handling and braking capabilities.

This generation of Trans Am was emblematic of the late 70s American muscle car era, and its popularity soared, in part, due to its starring role in the movie “Smokey and the Bandit.”
