Rare 1971 Plymouth Hemi GTX with 426 V8 and Four-Speed Manual Hits Auction Block

The Rarest of the Rare: 1971 Plymouth Hemi GTX Hits the Auction Block

Mecum Auctions will host its 2026 Indianapolis auction from May 8–16, 2026, showcasing a collection of rare pre-EPA muscle cars. Among the standout entries is a 1971 Plymouth Hemi GTX, a vehicle produced during the final years of unrestricted American muscle.

According to Mecum, this Hemi GTX is one of only 11 units from 1971 equipped with both the legendary 425-horsepower, 426-cubic-inch Hemi V8 and a four-speed manual transmission. Its rarity extends further—it is one of just four models featuring the Super Track Pack, which included 4.10 gearing and a Sure Grip limited-slip differential. Adding to its exclusivity, this GTX is believed to be the only 1971 model painted in Winchester Gray.

Unmatched Originality and Restoration

The car is meticulously equipped for its era, boasting:

• Power steering and power brakes
• Bucket seats
• Mopar Rallye wheels paired with Goodyear Polyglas tires featuring prominent white lettering
• The iconic Air Grabber hood with a pop-out slot instead of a fixed scoop

Undergoing a rotisserie restoration, the GTX retains its numbers-matching engine and transmission, preserving its authenticity and value.

A Muscle Car Icon: The Legacy of the Plymouth GTX

GTX once symbolized American muscle before Volkswagen rebranded it for European electric vehicles. Introduced in 1967, the GTX followed the classic muscle-car formula: a powerful V8 in a mass-market chassis. Positioned as a premium option, it competed directly with models like the Pontiac GTO and Oldsmobile 442. While the 440-cubic-inch V8 was a common choice, the Hemi V8 represented the pinnacle of performance.

The 1971 redesign introduced the fuselage design language, giving the car a more stylish, aggressive appearance compared to its predecessors. However, this era marked the beginning of the end for high-performance big-block engines. New emissions regulations and rising insurance costs forced automakers to dial back power outputs, making the 1971 Hemi GTX a relic of a bygone era.

Auction Expectations and Historical Significance

Mecum estimates this 1971 Plymouth Hemi GTX will sell for $325,000 to $350,000 when it crosses the block on May 15, 2026. For comparison, a manual 440-equipped GTX with matching numbers, also auctioned the same day, is expected to fetch $110,000 to $130,000—a stark contrast highlighting the premium placed on rarity.

The Plymouth brand may no longer exist, but the Hemi remains a symbol of raw power and performance. This 1971 GTX is not just a car; it’s a testament to an era when horsepower ruled and emissions regulations were nonexistent.
