When Plymouth unveiled the Road Runner in 1968, the response was overwhelmingly positive and it still remains among the most popular of muscle cars. Because of its success, it was only natural that Plymouth attempted to up the ante shortly following its release. The Plymouth Superbird came along in 1970 and it served as a modified version of the ever-popular Road Runner. It was built with the intent to appear in the NASCAR circuit, and as a part of the NASCAR rules, there had to be street-legal versions of this beauty.
Three engine options were available for the Plymouth Superbird: the 440 Commando, the 440 Super Commando, and the 426 Hemi. Only 93 units with the 426 Hemi were produced, which effectively made that particular option the rarest. In terms of power, the Super Commando 440 V8 engine produced 375 horsepower, while the 426 Hemi engine could produce 425 horsepower. The Superbird was a whopping 19 inches longer than its Road Runner counterpart, and just under 2000 units were produced. To add a little flare to the outside, some of the car’s graphics featured the likeness of the Road Runner from the classic cars.
Although the Plymouth Road Runner had enjoyed so much popularity, the Plymouth Superbird simply could not compete. No one could deny the overwhelming unpopularity of this particular muscle car, and so, it was only in production for one year. Its original base price was $4300 (equivalent to $25,500 in today’s dollars), but considering its rarity today, anyone in possession of a Plymouth Superbird is laughing all the way to the bank. Today, these cars go for about $70,000, and up to an impressive quarter of a million dollars.
