PLYMOUTH GTX AT THE BEGINNING
Introduced in 1967, the GTX was intended to be “the gentleman’s muscle car”, with a blend of style and performance. What started as a Belvedere, also the basis of the Roadrunner, was upgraded with new front and rear facia (shared with the Satellite), and coming standard with a 440 Magnum rated at 375hp and good for 6.5 seconds zero-to-60 and a 15.2-second quarter mile. If you had the extra $546, you could option up to the “Elephant Motor”, the almighty 426 Hemi with 425hp. The Hemi could rip to 60 in just 4.8 seconds and destroy the quarter mile in just 13.5 seconds at 105mph, unheard of for a production car at the time.
PLYMOUTH GTX EVOLVES
The GTX had a relatively short lifespan, from 1967 through 1971, when it ceased to be a stand-alone model. From 1972 through 1974, it was an option package on the Roadrunner. After just one year on the market, the GTX got a whole new sheetmetal skin for 1968, which remained fairly unchanged through 1971. Front and rear facia, trim and details were changed yearly. In 1970, the 440 Six-Pack was available, but only through the 1971 model year. As the muscle car era and performance declined, the need for a “gentleman’s muscle car” subsided, being filled by the new hot market segment, the “personal luxury car”, ie: Monte Carlo, Grand Prix, Thuderbird, etc. With the change in generations in 1971, the GTX became little for than a garish trim package.
