About the Plymouth Road Runner
The 1970 Plymouth Road Runner represents the final year of the first-generation B-body muscle car, famous for its 'beep-beep' horn and cartoon branding. Designed as a budget-friendly alternative to the upscale GTX, it focused on raw speed by stripping away luxury features in favour of heavy-duty hardware. The 383 cubic-inch 'Road Runner' V8 was the standard powerplant, offering a balance of reliability and punchy performance. Collectors value the 1970 model for its unique 'loop' front bumper design and the optional vacuum-operated 'Air Grabber' hood scoop.
