1971 GTX
- The famous “440 Six Barrel” was renamed the “440-6” in 1971.
- This was the last year for the GTX as a separate model, the 440+6 and the 426 Hemi. Plymouth was out of the upscale muscle car market. The GTX would live on as a performance option package of the more budget orientated Road Runner until 1974.
- This was the last year for the street Hemi and Chrysler only built 356 across all lines. Thirty of those ended up in the GTX. Eleven were mated to automatics and 19 came with the four speed transmission.
The GTX was completely redesigned for 1971. Plymouth compared it to an aircraft fuselage. The front end was low with a rap around bumper that did look like a jet engine intake. The rear sat higher than the front and made the car look lit it was moving even when sitting still. Performance was still good considering the overall environment of 1971.
The engine choices were carried over from 1970. The engines were some of the best ever produced and there was no need to change the lineup. As usual, the GTX received a heavy duty suspension and dual exhausts.
Sadly, the new GTX was doomed before it even came to market. Performance was not the most important consideration for young buyers anymore. Fuel economy and affordable insurance were the top priority in 1971. Sales were very meager at a little over 2,700 models sold. Only 30 cars received the mighty Hemi and only 135 buyers chose the 440 with the Six Pack option.
