1970 Plymouth Road Runner Hemi: Unleashing Power and Style on the Open Road

The 1970 Plymouth Road Runner Hemi was more than just a muscle car; it was a symbol of power and style that defined an era. As part of Plymouth’s “Rapid Transit System,” which showcased their most exhilarating vehicles, the Road Runner Hemi stood out with its freshened styling and bold features. Let’s take a closer look at this legendary automobile that captured the hearts of automotive enthusiasts.

Embracing the Spirit of the Times

In the vibrant 1970s, Plymouth embraced the spirit of the era with their Rapid Transit ads. These advertisements incorporated op-art graphics, flower-power imagery, and vibrant colors, reflecting the cultural zeitgeist of the time. The 1970 Plymouth Road Runner Hemi was one of the key players in this lineup, along with the redesigned ‘Cuda, the new Duster 340, and the restyled GTX. These muscle cars epitomized the essence of Plymouth’s “Rapid Transit System.”

A Memorable Introduction and Standout Features

One advertisement introduced the 1970 Plymouth Road Runner Hemi with a striking visual: a three-dimensional sculpture of the iconic cartoon Road Runner emerging from a trap door on the hood. The tagline, “The loved bird,” cleverly played on words while accurately depicting the car’s immense popularity. This photo also showcased a new and functional feature—the Air Grabber hood.

The Air Grabber hood was a standard feature on 1970 Plymouth Road Runners equipped with the 426-cid Hemi engine and optionally available on models with the 440 engine. With a simple flip of an underdash switch, the power-operated trap door would slowly rise, revealing a planed-off scoop adorned with a snarling shark cartoon. This attention-grabbing feature added to the car’s intimidation factor, making it a formidable presence on the road. The unique “beep-beep” horn sound, which became synonymous with the Road Runner, emanated from a purple underhood module, further enhancing its distinctive character.

Design Enhancements and Uncompromising Performance

Externally, the 1970 Plymouth Road Runner Hemi received restyled front and rear ends featuring handsome loop-motif designs and dummy rear-fender scoops. Under the hood, the powertrain remained largely unchanged, although the 426 Hemi engine underwent an upgrade from solid to hydraulic lifters for improved durability and cleaner emissions. The Road Runner’s standard four-speed manual transmission made way for a heavy-duty three-speed, which became an available option. Despite some changes, performance remained uncompromised.

The 1970 Plymouth Road Runner Hemi was a force to be reckoned with on the open road. Equipped with the legendary Hemi engine, it could accelerate from 0 to 60 mph in just 5.6 seconds and conquer the quarter mile in an impressive 13.49 seconds at 106 mph.

Sales and Legacy

While Plymouth Road Runner sales experienced a slight decline in 1970, with approximately 39,600 units sold compared to the previous year’s 43,400, the allure of the optional 426 Hemi engine remained strong. Only a limited number of hardtops, pillared coupes, and convertibles were fortunate enough to feature this iconic engine, with a total of 75 hardtops, 74 pillared coupes, and three convertibles receiving this powerful upgrade.

The 1970 Plymouth Road Runner Hemi continues to be revered as an automotive legend, representing the perfect blend of power, style, and performance. Its enduring legacy is a testament to its place in the hearts of automotive enthusiasts and its status as an icon of the road.

Conclusion

The 1970 Plymouth Road Runner Hemi remains an enduring symbol of power and style.
