The Plymouth Road Runner (or Roadrunner) is a mid-size car with a focus on performance built by Plymouth in the United States between 1968 and 1980. By 1968, some of the original muscle cars were moving away from their roots as relatively cheap, fast cars as they gained features and increased in price. Plymouth developed the Road Runner to market a lower-priced, basic trim model to its upscale GTX.
Plymouth paid $50,000 to Warner Bros.-Seven Arts to use the Road Runner name and likeness from their Wile E. Coyote and the Road Runner cartoons (as well as a “beep, beep” horn, which Plymouth paid $10,000 to develop).[1] The Road Runner was based on the Chrysler B platform (the same as the Belvedere and Satellite), as a back-to-basics mid-size performance car.
