Plymouth Superbird

The Plymouth Superbird is a highly modified, short-lived version of the Plymouth Road Runner with applied graphic images as well as a distinctive horn sound, both referencing the popular Looney Tunes cartoon character Road Runner. It was the factory's follow-up stock car racing design, for the 1970 season, to the Dodge Charger Daytona of 1969, and incorporated many engineering changes and modifications garnered from the Daytona's season in competition.
