1970 Plymouth GTX
The GTX – a 2-door hardtop or convertible – was first introduced by Plymouth in 1967. Design-wise, the Plymouth GTX was certainly appealing, and not just by its looks. Each vehicle came with performance-enhancing upgrades, like modified shocks, leaf springs, torsion bars, etc. The base engine was impressive as is: a 440 cubic-inch V8 called the Super Commando 440. At a breath-taking 375 horse powers, it met or beat previous drag straights’ times and could accelerate from 0 to 60mph up to 126mph. No other car of its time could outperform it in this regard: indeed, Plymouth has gone out of the ordinary with GTX’s acceleration. Surprisingly, not even 800 buyers wanted the upgraded, 425 horse power optional 426 Hemi engine. The automatic, 3-speed TorqueFlite gear system could be upgraded to a manual 4-speed transmission for a set fee upon purchase.
Car dimensions were as follows
- Wheelbase – 115”
- Length – 200”
- Width – 76”
- Height – 54”
- Front track – 60”
- Rear track – 59”
- Trunk capacity – 21.6 cubic feet
- Fuel capacity – 19 gallons
- Total weight – 3,550 lbs
For extra cash, features like air conditioning and power steering and power brakes could be included. Power-windows and sure-grip differentials were also available. Newly introduced 1969 options were impressive: unlike previous models, new buyers could opt in for an air grabber, a Hurst shifter, and variable rear axles. With three different engine options, Plymouth offered people a lot to pick from, but not many customers actually did so.
Like the Road Runner, Plymouth took everything out of the GTX, as well – including carpeting, radio, and car heater, making it a cold ride in the winter time. 1968 brought two kinds of changes to the GTX: mechanical and aerodynamic. An improved hood was added, and suspension was modified. Also, the designers gave the new GTX wider tires and a limited slip differential. A different grill and taillights were put in place, and frontal disc brakes were used, as well. The Road Runner, however, simply seemed like a better option in terms of performance, meaning less sales for the Plymouth GTX.
In 1971, the executives at Chevrolet decided to make the Plymouth GTX an upgrade for the 1972 Road Runner rather than a separate brand model. This signified the end of Plymouth GTX era.
