When Plymouth decided to apply airplane-inspired “fuselage” styling to their range of intermediate cars, they took it to the next level on with the GTX by adding intricate twin tailpipes that vaguely resemble jet engines. This car shares its styling with the related Satellite coupe and the more spartan Road Runner, but understatement doesn’t play a role in the over-the-top GTX. Loud and proud, the high-performance Plymouth wears a contrasting vinyl roof on the semi-fastback design, a large rear-deck spoiler, and plenty of “GTX” badging. Looks aren’t the only outrageous part of the GTX—when equipped with the rarely-optioned 426 Street HEMI engine option, the GTX is good for 425 horsepower, more than enough to run the quarter in the 14s. Less than 3,000 GTXs were produced in 1971, and a very small amount left the lot with this configuration, one of the best implementations of Mopar’s “Elephant Motor.” If you were interested in going around a corner rather than simply blasting down the strip, the stiff suspension and wider rear track make the 1971 GTX a noticeably better handler than the car it replaced. Unfortunately, as the muscle car wars wound down, 1971 proved to be the last year of the GTX.
