Ford Thunderbird Turbo Coupe
The Ford Thunderbird Turbo Coupe falls among the worst muscle cars due to its departure from the traditional Thunderbird luxury image. Introduced in the ’80s, the Turbo Coupe aimed to infuse sportiness into the lineup but struggled to strike a balance. Its forced-induction engine and handling enhancements failed to resonate with Thunderbird enthusiasts, leaving this model as a somewhat misguided attempt at blending performance and luxury, earning it a place on the list of disappointing muscle cars.
