Plymouth GTX

The Plymouth GTX is an automobile introduced as the Belvedere GTX in 1967 by the Plymouth division. It was positioned as a mid-sizedupscale-trimmed performance muscle car through the 1971 model year. The GTX was based on the Belvedere, but differentiated by blacked out grille and special rear fascia, fiberglass simulated hood scoops with optional racing stripes, a chrome "pop-open" fuel filler cap, and a tachometer mounted on the center console.[1]

The GTX was positioned as a "gentleman's" muscle car.[2] Standard was Plymouth's 440 cu in (7.2 L) V8 engine called the "Super Commando 440" rated at 375 hp (280 kW). Optional was Chrysler's 426 cu in (7.0 L) Hemi. A heavy duty suspension system was also standard. Chrysler introduced major changes in the design of the 1968 model Plymouth B-bodies and the GTX was given a completely new look. A new hourglass body replaced the previous rectilinear design. The high performance 440 was standard in the GTX. The TorqueFlite automatic transmission was standard on the GTX, while it was an extra cost option in the Road Runner. The GTX used the Sport Satellite trim and was offered in two body styles, a two-door convertible and a two-door hardtop (no B-pillar). All featured dual horizontal "racing stripes" on the lower sides ending with a GTX emblem ahead of the rear wheel openings.

The GTX was positioned to be upscale model of the Plymouth Road Runner by adding a touch of luxury to performance.[3] The new budget performance version of the Belvedere featured the new 383 cu in (6.3 L) "Super Commando" V8 (renamed the "Road Runner 383"). It also had less insulation and comfort items, which reduced weight and kept it in the low price field.
