Mecum is set to host its 2026 Indianapolis auction from May 8-16, and as expected for such events, there will be an abundance of rare muscle cars from the pre-EPA era. One of the most exceptional is this 1971 Plymouth Hemi GTX, which rolled off the assembly line toward the tail end of that timeframe.
As per Mecum, this model is among just 11 units from 1971 equipped with the 425-horsepower, 426-cubic-inch Hemi V8 coupled with a four-speed manual gearbox. Additionally, it is one of a mere four that includes the Super Track Pack, boasting 4.10 gearing and the Sure Grip limited-slip differential. It is also believed to be the sole 1971 Hemi GTX finished in Winchester Gray. A skilled graphic designer will be needed to display all this information on a car show board.
Moreover, this car is outfitted exceptionally well for its era. Features include power steering and brakes, bucket seats, and the classic pairing of Mopar Rallye wheels alongside Goodyear Polyglas tires with noticeable white lettering. It is equipped with the unique Air Grabber hood, featuring a pop-out slot in place of a standard fixed scoop. The vehicle underwent a rotisserie restoration yet retains the original matching engine and transmission.
Before Volkswagen adopted the GTX nomenclature for its European electric models, GTX symbolized American muscle. Introduced in 1967, it adhered to the traditional muscle-car template of fitting a powerful V8 into a widely available chassis. It was marketed as a more luxurious option, paving the way for the Road Runner (which debuted the following year on the same Chrysler B-Body platform) and offering Plymouth a legitimate rival to the Pontiac GTO, Oldsmobile 442, etc. Like many other Mopar muscle cars, it could be outfitted with the 440-cubic-inch V8 in addition to the Hemi.
The GTX alongside other B-Body models underwent a redesign for 1971, following the introduction of the new “fuselage” design language, which is underappreciated, in my personal view. These cars possessed a bit more character compared to the conservatively styled predecessors. However, the fuselage models arrived at a time when manufacturers were beginning to prepare for new emissions regulations, and insurers were noticing that vehicles with both power and low cost were detrimental to their business. With its powerful 426 engine, the 1971 Plymouth Hemi GTX marked the conclusion of an era. In just a few years, the big V8s would be either toned down or completely retired.
Although the Plymouth brand has been long discontinued (not even the Prowler could revive it), the term Hemi remains widely recognized. Mecum anticipates this vehicle will fetch between $325,000 and $350,000 when it goes under the hammer on May 15. A manual 440 version (also with the original engine and transmission) is set to be auctioned on the same day but is only projected to bring in $110,000 to $130,000. That illustrates the power of rarity.
