17. Dodge Charger Daytona (1976 to 1977)
You are probably familiar with the original Dodge Charger Daytona from 1969, a big coupe based on Dodge Charger with a pointy nose and massive rear wing, designed for racing in NASCAR and produced in only 500 examples. Less than 10 years after the memorable Daytona, Dodge decided to use this glorious name again in a terrible case of self-reinventing (via Garage Kept Motors).
They did it this time on the Dodge Charger, which was a Chrysler Cordoba, a two-door luxury coupe with no muscle car credentials whatsoever. The move was not well-received since the Cordoba had a lame 145 HP V8 engine and was more focused on luxury than performance and driving dynamics. Fortunately, buyers punished Dodge for using the precious Daytona nameplate.
