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 the 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 (both minor and major) garnered from the Daytona's season in competition.
The car’s primary rivals were the Ford Torino Talladega and Mercury Cyclone, a direct response to the Mopar aero car. It has also been speculated that a motivating factor in the production of the car was to lure Richard Petty back to Plymouth. Both of the Mopar aero cars famously featured a protruding, aerodynamic nosecone, a high-mounted rear wing and, unique to the Superbird, a horn mimicking the Road Runner's signature “beep, beep.”
Superbirds equipped with the top-of-the-line 426 cu in (7.0 L) Hemi engine with a pair of four barrel Carter AFB carburetors (2x4bbl) producing 425 hp (317 kW) could accelerate from 0 to 60 mph (97 km/h) in 5.5 seconds.
