Chrysler gave its B-body cars a new body in 1968 for the Dodge Coronet, Dodge Charger, Plymouth Belvedere, and Plymouth Satellite. The Plymouth Belvedere GTX was reworked to give it more youth appeal and in a moment of inspiration the name 'Road Runner' was chosen and Warner brothers were paid 50,000 dollars for it. The Road Runner got the Belvedere body stripped out and powered with the 383 (6.3-litre) engine, but tuned with the parts from the 440 engine. For 1971 a new B-body was introduced. 'Fuselage' styling was given to all 1971 Chryslers, and 2-door cars shared little with 4-door cars. Insurance premiums were rising for muscle cars but Road Runner 340 and 383 cars paid normal rates; the 6-barrel 440 and the 426 Hemi were still available. 1973 and 1974 Road Runners received new panels in line with other Chrysler models. The final Road Runner was released on the 1975 B-body for one year only, but there was a Road Runner trim option on the 1976 F-body Volare.
