9. Dodge Diamante Challenger Concept
Dodge maybe did come late to the pony car segment with the 1970 Challenger but immediately showed that they are there to stay since the Challenger was a great muscle car with iconic styling and a lineup of powerful engines. However, Dodge wanted more and wanted to see if the Challenger could be transformed into a sports car that could rival the Corvette.
That is why the Diamante concept car was born. This example started its life as a highly optioned Hemi convertible which was turned to Yellow Jacket show car but then Dodge took it back to the styling department and re-imagined it as Diamante. The car received a new front and rear end, two-seater interior, different turbine-style wheels, and an interesting Targa top. With 426 Hemi under the hood, the Diamante was fast and with the custom side, pipes exhaust it sounded awesome, too.
