> Muscle Car Specifications > Plymouth Specs 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.
