1970-1979 Dodge GTX: Argentina’s Long-Lived A-Body Muscle Car

What had curvy body lines à la ’68-’70 Dodge Coronet, rode a 1966 A-body platform, shifted via a 4-speed manual, and offered old-school muscle car flavor well into the late 1970s? A South American Mopar: Argentina’s muscular 1970-1979 Dodge GTX, powered by Chrysler’s 318CID V-8 with 212HP. It wasn’t the most powerful A-body ever by US standards, but the GTX was Argentina’s mightiest factory performance model, a halo car that still enjoys a loyal following today.

Before we get too carried away, let’s backtrack a bit. Assembly of Chrysler products had begun at Argentina’s Chrysler Fevré factory in 1960, starting with trucks in 1960 and the Valiant in 1962, with the usual engineering tweaks required by local needs. Local variations on the A-body formula started early, with Argentina’s Valiant III appearing in 1964, using the looks and stretched wheelbase of the American Dodge Dart.  From then on, Argentina’s A-body branch turned toward Dodge, discarding the Valiant name in 1968, and with Dodge taking over wholly that year, wearing the updated looks of the American 1967 A-body line (with minor styling tweaks).

1969 offered updated looks that mixed and matched MoPar styling themes, with headlights shared with the Renault 12 (and others), and that spoke to styling intentions that couldn’t happen in the US yet.

Darts came in Polara, GT and Coronado models, and the advertising above made comparisons to Argentinian Fords; though AMC’s Ambassador and Chevy’s Nova were also contenders in that segment.

Talking about which, such American models were generally upper class material in Argentina; their larger size, higher fuel consumption, and lofty acquisition costs meant that yearly, they sold in the low four figures at best. But “US built” (or US origin in this case) still carried strong positive connotations, and they served as halo cars for US carmakers that had set up Argentinian production. Of course, each maker’s focus was to also offer a volume seller; in the case of Chrysler-Fevré, that would eventually be the Dodge 1500 (Cricket/Hillman Avenger).

Choosing to increase their halo car credentials, the GTX arrived in 1970 wearing “fuselage-light” styling to take over the Dart GT’s sporty mantle, and with Chrysler appropriately boasting about the 318CID’s found in the GTX as the “…nation’s most potent V8”. For shifting, the car came with Chrysler-Fevré 4-speed unit, derived from Chrysler’s 3-speed A-230 (now, the A-230/4).

That said, there was still some tweaking going on, since the Slant Six A-119 in 155HP tune was still offered in ’70-’71 on the GTX. Realizing that muddied the waters, the A-119 Six was dropped for ’72 (moving to a new model, the Polara Coupé), leaving the GTX solely devoted to its Muscle Car role until production ceased in 1979.

Early GTXs still wore fuzzy detailing upfront, similar to the 1968 lineup, while the vinyl top was part of the package. Elsewhere on the body, the fuselage hips gave them a distinctive look that hinted at the powertrain underneath.

As for performance, the car delivered on what its buyers expected, offering American style straight-line acceleration, smooth highway cruising, and a comfortable cabin for long-distance travel. Not sure how this translated to Buenos Aires (never been there; South American readers, fill in those details), but that worked in that nation’s long stretches between cities.

Further styling updates arrived for 1972, with a generally cleaner look.

As for the interiors, faux wood was the norm. Also, they look Dart-Valiant in feel, but one can see that some details are tailored to local market expectations.

Old American iron has a following just about everywhere, with Argentina not being an exception. These GTXs clearly have their fans, and they perform the usual styling upgrades now expected in such survivors.

And while my brain is still going through cognitive dissonance seeing that GTX badge on a Dodge, I’ll admit it looks mighty pretty on those fuselage-light rear fenders.

There’s definitely more to this rabbit hole of South American Chryslers, like the A-body remaining in production in Argentina all the way to 1981. But that will do it for today’s brief look at South America’s funhouse mirror study of American-derived models built there.
