#4 – 1970 Plymouth Road Runner Superbird
There might not be a more distinctive classic muscle car than the Plymouth Road Runner Superbird. Road Runners were already well respected performance machines when Plymouth decided to up the ante with the Superbird. The comically massive spoiler helps the Superbird keep its wheels on the pavement, while the sharp front end makes it more aerodynamic than many classic muscle cars with their flat front end. Despite weighing nearly 4,000 pounds, the Superbird could hit 60 miles per hour in just 5.6 seconds. You can thank the massive 426 Hemi engine for that speed.
Quick Fact: The Superbird came in seven different colors, all with a black vinyl roof minus racers.
