1967[eedit | eedit soorce]
It wis tae be an exceptional blend o style an performance. What differentiated it frae a normal Belvedere wis its special grille an rear fascia, shared wi the Satellite, as well as mock hood scoops, chrome "pit stop" fuel filler cap an optional racin stripes. For the performance aspect o the vehicle, a hivy duty suspension system wis made standard. Standard too wis Plymouth's 440 cu in (7.2 L)V8 called the "Super Commando 440". The ingine wis ratit at 375 hp (280 kW). Buyers in 1967 coud pay an extra US$546 an replace the 440 wi Chrysler's 426 cu in (7 L) Hemi. The 426 wis nicknamed the "Elephant."
1968[eedit | eedit soorce]
In 1968, after ane year o production, the GTX wis given a completely new look. A new hour glass body replaced the more box like body o 1967. The Road Runner wis introduced bi Plymouth as a performance version o the Belvedere. There wur major changes made in the design o all the Plymouth B-bodies. The Road Runner's base ingine wis the new 383 cu in (6.3 L) "Super Commando" V8 (renamed the "Road Runner 383"), while the hicht performance 440 wis still standard in the GTX. The TorqueFlite automatic transmission wis standard on the GTX, wi it being a US$206 option in the Road Runner. The GTX wis still based on the Satellite an wis offered in twa models, the 2-door convertible an the 2-door hardtop. The Road Runner wis based on the Belvedere, an haed less insulation an comfort items (paddin, vinyl roof, trim), which reduced weight, helped produce better track times, an kept it in the loa price field.
1969[eedit | eedit soorce]
In 1969, the GTX's sales wur hurt when the Road Runner wis also offered in a convertible body style. The GTX received minor cosmetic changes, as well as the introduction o the optional Air Grabber hood (standard on Hemi-ingined models), which made the hood scoops functional. The standard 440 V8 wis still rated at 375 hp (280 kW). The 69 GTX wis the last year that the convertible model wis available on the GTX (VIN RS27). Chrysler Corporation anerlie made 701 GTX convertibles in 1969. O those, elieven wur equipped wi the 426 Hemi; fower 4-speeds an seiven TorqueFlite automatics.
The 1969 GTX also haed standard black lawer body side paint, replacin the dual, horizontal "racin" stripe on the lawer sides o the 1968 model.
1970[eedit | eedit soorce]
The 1970 GTX received a major redesign but sales still suffered. Stylists made the lines smoother, an a "pouer bulge" hood wis introduced, as well as nan-functional rear brake air scoops. The convertible model wis dropped in 1970. The Air Grabber hood wis brought back, but instead o having twa narrow openins runnin length-wise as in 1969, it haed ane openin scoop locatit on the pouer bulge. The GTX wis available wi the standard 440 4 barrel, as well as the 440+6 barrel (three twa barrel carburetors) an the 426 Hemi. The 440+6 coud compete closely wi the Hemi, up tae hieway speeds. In keepin wi the GTX marketin strategy, the 1970 model includit mony standard features. The anerlie ither Plymouth luxury/performance model wis the full-size Sport Fury GT, built on the C-Body platform. The GT wis addit tae the lineup in 1970. The GT received naewhere near the recognition o the GTX, even though they shared mony performance features. The Sport Fury GT wis the full-size member o The Rapid Transit System. The Sport Fury GT wis aften viewed as more o a mature gentleman's performance luxury caur.
1971[eedit | eedit soorce]
Though completely redesigned for 1971, this wis the final year for the GTX as a stand-alane model with anerlie a manual transmission. Ingine choices wur 440 fower-barrel, 440 wi three twa-barrels (Sax Pack) , an 426 Hemi. Emission restrictions such as lawer compression ratios an faster-actin choke operation lowered the base 440 output bi 5 hp (3.7 kW), tae 370 hp (280 kW). The 440 Sax Pack wis doun tae 370 hp (280 kW), but the Hemi wis still rated at 425 hp (317 kW). Due partly tae risin insurance rates on muscle caurs, sales wur law. There wur less than 3000 units produced in '71. For 1972 through 1974 the GTX became an option package on the Road Runner.
