About the Plymouth Road Runner Hemi
Introduced in 1968, the Plymouth Road Runner was designed as a back-to-basics muscle car that prioritised raw performance over luxury. While the 383 V8 was standard, the 426 Hemi was the ultimate option, featuring dual four-barrel carburetors and a heavy-duty drivetrain. The 1969 model year is highly coveted, having won Motor Trend's Car of the Year award. It is distinguished by its spartan interior, 'Air Grabber' hood, and the iconic 'beep-beep' horn licensed from Warner Bros. Collectors prize the Hemi version for its rarity and its status as one of the fastest accelerating cars of the era.

Plymouth Road Runner Hemi fun facts
- Plymouth paid Warner Bros. $50,000 to use the Road Runner name and likeness, plus $10,000 to develop the signature 'beep-beep' horn.
- The 426 Hemi engine was so large that it left no room for an air conditioning compressor, making it unavailable on Hemi-equipped cars.
- Only 10 Hemi Road Runner convertibles were produced in 1969, making them some of the rarest and most valuable Mopar muscle cars in existence.
