Plymouth Superbird
As one of the craziest muscle cars ever produced, the Plymouth Superbird had one of the most recognizable graphics packages ever presented to the general public. The Superbird attempted to win the famous Aero Wars in the late ’60s and early ’70s NASCAR championship. To homologate the car for racing, Plymouth built just under 2000 road-going Superbirds and sold them all over America (via Trust Auto).
The car was based on the Roadrunner and came with a 440 V8 standard and the 426 Hemi as the only engine option. However, to make it as aerodynamically efficient as possible, Plymouth installed a nose cone, hideaway headlights, and an enormous spoiler in the back. Also, it transformed the rear glass from the standard concave-shaped one to regular, which proved more slippery in wind tunnel testing. The Superbird came with a wild graphics package and bright colors. All cars had vinyl roofs to hide the rear glass conversion scars, large “Plymouth” lettering on the rear fender, and a roadrunner bird logo holding a racing helmet. This was muscle car art at its finest and in its prime.
