AMC Eagle SX/4
The AMC Eagle SX/4 secures its place among the worst muscle cars due to a combination of uninspiring performance and a departure from the traditional muscle car aesthetic. Introduced in the early ’80s, the SX/4 aimed to blend off-road capability with sporty design but fell short. Its modest power and conservative styling failed to resonate with muscle car enthusiasts, leaving the SX/4 as a forgettable entry in the world of muscle cars. The lack of true muscle car attributes marks it as a disappointment in the category’s history.
