1971 Plymouth Road Runner

Other Years:

General Overview

The 1971 Road Runner was part of the Satellite group and its bodywork was completely changed to a more rounded "fuselage" design.

It included a steeply raked windshield, hidden cowl, and deeply inset grille and headlights. The convertible was canceled, and the coupes no longer shared sheet metal, glass, or trim with the four-doors. Length was decreased while wheelbase was actually increased. Sway bars were added in conjunction with staggered rear leaf springs resulting in overall better handling and cornering without a stiff ride.

It also saw the introduction of a new 340-4bbl option, and a detuned Road Runner 383 with 8:7 compression that dropped power to 300 hp. In return for this, buyers received a standard insurance rating without costly premiums. In addition to cheaper insurance, the 383 could also run on regular gas.

Aerodynamics were also much improved over previous years that helped with high-speed handling.
