The Plymouth GTX of 1970 :

The 1970 GTX received new smoother lines. Low sales caused the removal of the convertible.

The new styling featured a power bulge hood and non-functional rear brake scoops. The new change included a revamped nose with a B-shaped grille.
The "Air Grabber" option continued, the air was forced through a trapdoor that would pop up when the driver activated a switch on the instrument panel.
Optional 15x7 Rallye wheels became available for the first time.

Under the hood, buyers could choose from a 440 with 375 bhp, the 440+6 with 390 bhp and the big 425 bhp of the 426 Hemi.

Optional with the 440+6, and standard with the Hemi was the latest version of the Air Grabber hood. Typical of the time, the flap featured a shark decal on the side.

The GTX was always heavier than the Road Runner and thus it was slower.

Sales continued to suffer and only 7,202 GTX were sold.
