History
Launched for 1968, the Road Runner was Plymouth's answer to soaring muscle-car prices: a stripped-down, low-cost B-body with a bench seat, minimal trim, and a standard 383 big-block V8. Plymouth paid Warner Bros.-Seven Arts $50,000 to license the Looney Tunes Road Runner name and likeness — and another $10,000 to engineer the car's distinctive 'beep, beep' horn.
Top engines included the 426 Hemi (425 hp, 1968–1971) and the 440 'Six Barrel' (triple two-barrel carbs, 390 hp). The aerodynamic, winged 1970 Superbird was a NASCAR-homologation Road Runner spin-off.
The first generation (1968–1970) is the icon; a 'fuselage'-styled second generation followed (1971–1974). As emissions and insurance pressures gutted the muscle era, the name survived as a trim package — on the 1975 B-body, then on the compact Volaré through 1980.
