Plymouth Road Runner Superbird 1970
The Superbird version of the Road Runner was an effort to dominate NASCAR racing with Chrysler products in 1970. The Plymouth Superbird only saw one season of racing before it was felt the sloped nose and giant rear wing gave the car an unfair advantage. The Superbird was built atop the same mid-sized Chrysler platform as the Dodge Charger, but the two cars were uniquely different, evident in the bodywork. The rear wing on the production based cars did little other than turn heads. It was given this height so that is could allow enough room for the trunk lid to open without interference with the wing. For the NASCAR entries, the angle of the wing and the height were carefully tested for each track to provide optimal performance at speeds. Most of the road-going Superbirds were equipped with plenty of luxury and convenience options, as well as performance equipment. The NASCAR season-opener was the Daytona 500 which was won by Pete Hamilton driving a Petty Enterprises Plymouth Road Runner Superbird. Petty's Superbird appears as a key character in the 2006 Pixar film Cars, with Petty as the voice of seven-time champion Strip “The King”.
