Plymouth GTX (1967 to 1971)
Introduced in 1967 as a luxury option in the Belvedere lineup, this model was based on the same platform as the Coronet. However, it was much more luxurious and had 375 horsepower and 440 V8 as a standard. Plymouth wanted the GTX to compete with luxury cars of the period, so it installed almost all possible creature comforts along with some unique trim on the outside to distinguish the GTX from the rest of the model lineup. The GTX was a gentleman’s hot rod with all options, lovely interior and exterior details, and only one optional engine choice – the mighty 426 Hemi. The 440 Magnum was the standard engine but if you wanted the ultimate Plymouth muscle luxury, you had to get the Hemi (via Muscle Car Club).
Because it was significantly more expensive than the rest of the Mopar muscle car lineup, the GTX was never that popular. As a result, it’s quite rare today. When the early ’70s came, and all muscle cars started to lose power and torque figures, Plymouth discontinued the GTX in 1971, keeping it from being a disgrace to its fire-breathing predecessors. This is why the ’71 GTX is the last of its breed and a fantastic muscle car.
