Chevrolet Citation X-11
The Chevrolet Citation X-11 claims its spot among the worst muscle cars with a combination of lackluster performance and unremarkable styling. Introduced in the early ’80s, the X-11 aimed to inject sportiness into the Citation line but fell short. Its modest power and uninspiring aesthetics failed to resonate with muscle car enthusiasts, leaving the X-11 as a forgettable chapter in Chevrolet’s attempt to infuse performance into a more mainstream model. The lack of true muscle car attributes marks it as a disappointment in the category’s history.
