The 1970 Plymouth Road Runner was the last of the first-generation Road Runner, and part of the Plymouth Rapid Transit System — a special line devoted to its performance cars available in “high impact” colors like Lemon Twist, Vitamin C, and In Violet. The 440 six-barrel engine became a regular option, and the fresh air or “Air Grabber” system was changed to a vacuum-activated hood scoop, operable by the driver.
The Revell 1/24 scale 1970 Plymouth Road Runner plastic model kit was first released in 2000 but dates back to a Monogram 1970 Plymouth GTX kit from 1982.
