1971 Plymouth Road Runner / GTX

The 1971 Road Runner and GTX featured an all new design. Plymouth called it “fuselage” styling as it included many curves and rounded features. The wheel base was 1 inch shorter but 3 inches wider which would hopefully improve handling.

Inside the car was also redesigned and was far superior comfort compared to past models. High back buckets were standard. Many new options were available to dress up the car such as a rear spoiler, electrometric bumpers, and window louvers.

This was the last year of true performance offered by the Road Runner. It was also the last year for the GTX and for the 426 hemi engine option in any Mopar.
