Dodge St. Regis
The Dodge St. Regis makes its mark among the worst muscle cars due to a combination of uninspiring performance and a departure from the traditional muscle car image. Introduced in the late ’70s, the St. Regis featured conservative styling and lacked the powerful engines associated with its muscle car counterparts. Its underwhelming performance failed to capture the excitement associated with this automotive category, making it an unfortunate deviation from the muscle car legacy.
