45. 1970 Plymouth Hemi Superbird
Basically a modified Road Runner (see lower down on the list), the Hemi Superbird was designed for racing down super speedways. Not many were built or sold, but they were undeniably fast! They also had a very unique look, would may have attributed to its low sales.
With a 426 Hemi engine and a pair of four-barrel Carter AFB carburetors producing 425 HP, the Hemi Superbird could accelerate from 0 to 60 mph in 5.5 seconds. The only reason this car was made is so it could be run in NASCAR races.
The looks were extreme for the time, though. With a huge rear spoiler and coke bottle shape, it was designed more for aerodynamic performance than looks. The calculations on how the rear spoiler was designed were even kept secret by Pontiac for almost 30 years. Due in part to low sales, many dealers removed the spoiler and converted the car to a Road Runner. Even today, you can buy kits to convert the Superbird to a Road Runner.
Though most of America didn’t get a chance to drive one, Richard Petty did, and he said they are pretty darn fast. His went over 200 mph!
