1970 Plymouth Road Runner Superbird

In 1970 the Plymouth Road Runner Superbird was one of many muscle cars that served a dual purpose along with other muscle cars like, Dodge Charger R/T, Ford Torino GT, Mercury Cyclone Spoiler GT and Plymouth’s basic Road Runner. They were not only prime candidates for the ultimate in street rod muscle, their characteristics were noted by NASCAR to be worthy of using on super speedways. Car manufacturers took this interest very seriously. NASCAR meant big advertising for the manufacturers, what could be better endorsement for companies than having big named drivers such as Richard Petty , Buddy Baker, Norm Nelson or Cale Yarborough win the Daytona 500 in a car designed and made by your company.

With big named drivers of NASCAR endorsing muscle cars like Plymouth Superbird it gave the company incentive to get the project into high gear. In 1969, Richard Petty, who until then had raced and driven numerous Plymouth’s to victory, did the unexpected and moved over to the Ford racing team. Petty was not happy with the new 1968 Plymouth Road Runner body style, he felt it was not aerodynamically friendly compared to the Ford equivalent. Buddy Baker made a good showing with his ‘69 Charger Daytona, with unheard speeds of 200 mph. Plymouth was determined to win Petty back and was willing to do anything necessary to accomplish this. After Dodge discontinued the Charger Daytona in 1969, Plymouth applied the aerodynamic technology to the Road Runner in 1970, in respect, winning Richard Petty back to their team.

With some similarities between the ’69 Charger Daytona and the ’70 Superbird, the only true similarities are the front fenders and the windshield, which like the Charger Daytona were borrowed from the 1970 coronet. Their nosecones and tall rear wings looked identical, but were not interchangeable. The nose cone on the Superbird points downward with the grille on the underside, as on the Daytona it’s in the front center of the nose cone. The headlights and turn signals are different as well. The rear wing is more swept back on the Superbird, but adjustable like the Daytona.

Although Plymouth made many more of the Superbirds than Dodge’s Daytona, that doesn’t say Plymouth had better luck with the public buying these long nosed tall winged unsightly (as perceived by public opinion) aero cars. As did the Daytona, the Superbird sat on dealers’ lots as far ahead as 1972, until most dealers removed the nose cones and tall spoilers and installed standard Road Runner equipment to move them off their lots. Even with the sales problems then, today the sale prices range from $100K to $300K and up, making them one of the most sought after Mopar’s today.
