1968 Plymouth GTX

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.

1969

In 1969, the GTX's sales dropped when the Road Runner was also offered in a convertible body style. The GTX received minor cosmetic changes to the tail lights and grille, as well as the side marker lights. An optional Air Grabber hood (standard on Hemi-engined cars) featured functional openings on both sides of the hood that were controlled from the dash.^[4]

The 1969 GTX received had standard black lower body side paint in place of the previous stripes. The standard 440 V8 was still rated at 375 hp (280 kW). This was the last year that the convertible model was available on the GTX (VIN RS27). Total production was 701 GTX convertibles in 1969. Of those, eleven were equipped with the 426 Hemi; four 4-speeds and seven TorqueFlite automatics.

1970

The 1970 GTX received a minor redesign with a new grille and rear taillights. Sales were low as the car did not look much different from the Road Runner. Stylists made the lines smoother, and a "power bulge" hood was introduced, as well as non-functional rear brake air scoops. The convertible body style was no longer available. The Air Grabber hood returned, but instead of having two narrow openings running length-wise as in 1969, it had one opening scoop located on the power bulge. The GTX was available with the standard 440 four-barrel carburetor. Optional were the 440+6 barrel (three two-barrel carburetors) and the 426 Hemi. In keeping with the GTX marketing strategy, the 1970 model included many standard features.

The only other performance luxury model in Plymouth's lineup was the full-size Sport Fury GT, built on the C-Body platform. The GT was added to the lineup in 1970.
