The Rarest Plymouth Ever Made Isn’t a Hemi ‘Cuda—And It’s Vanishing
Few cars embody the golden era of muscle cars like the Plymouth Hemi ‘Cuda. The ultimate expression of Hemi-powered muscle, the Hemi ‘Cuda is a dream car for generations of enthusiasts, but its convertible variants are the real unicorns. Plymouth produced roughly 780 Hemi ‘Cudas between 1970 and 1971, and only around 25 were convertibles: about 14 from 1970 and 11 from 1971.
The hardtops are already blue-chip muscle, routinely bringing high six-figure sums, but the ultra-scarce ragtops have reached entirely different territory. In January 2026, a 1971 Hemi ‘Cuda convertible changed hands for $3.3 million at Mecum, showing just how far scarcity can push values. Yet there is an even rarer Hemi-powered Plymouth, built years before the ‘Cuda, that remains largely overlooked by enthusiasts and collectors alike.
The 426 Hemi Created Muscle Car Unicorns
In 1960s America, “win on Sunday, sell on Monday” was practically gospel, and Chrysler wanted the checkered flag. Its answer arrived in 1964: the 426 Hemi, a purpose-built racing weapon with hemispherical combustion chambers that helped it breathe deeper and make serious power, giving Chrysler a decisive edge on NASCAR’s high banks. At the 1964 Daytona 500, it proved the point spectacularly, powering a Plymouth 1-2-3 finish with Richard Petty running away from the field and even lapping the competition.
The Hemi was so dominant that NASCAR changed its homologation rules for 1965, effectively forcing Chrysler to make the engine available in production vehicles. The resulting Street Hemi arrived in 1966 with 425 horsepower and 490 lb-ft, then terrorized both drag strips and back roads until production ended after 1971. Since it was never a cheap option, Chrysler ultimately built just under 11,000 customer Street Hemi cars, making genuine Hemi Mopars muscle-car unicorns from the outset.
Everyone Wants A Hemi ‘Cuda, But Is It The Rarest Hemi Plymouth?
When enthusiasts picture the ultimate factory Hemi Plymouth, the Hemi ‘Cuda usually comes to mind first. Sitting at the top of the Barracuda range, the ‘Cuda could be ordered with several engines, but the 426 Hemi transformed it into the stuff of muscle-car legend. The 1970 and 1971 cars combined knockout E-body styling with serious Hemi power and last-of-the-era status, while their scarcity made them collector royalty.
Plymouth built an estimated 780 Hemi ‘Cudas across those two years, including just 21 convertibles by some widely cited counts. The $3.3 million fetched by a 1971 Hemi ‘Cuda Convertible at Mecum in January 2026 is staggering, but it is not the first Hemi ‘Cuda to reach Bugatti money, nor the most expensive example ever sold. More importantly, there is a considerably rarer Plymouth Hemi lurking in the shadows, one that somehow never became the collector-world superstar the ‘Cuda did.
The 1967 Plymouth Hemi Satellite Is Rarer Than Any Hemi ‘Cuda
The mystery car is the 1967 Plymouth Hemi Satellite, and its production story is almost as unusual as the car itself. Sources disagree on exactly how many left the factory, but the commonly cited maximum is just six examples. Some records put the number even lower at three: two hardtop coupes and one convertible. Either way, the numbers are remarkable. That means the 1967 Hemi Satellite was scarcer than every Hemi ‘Cuda convertible built in 1970 and 1971, including the legendary 11-car 1971 run. Most production accounts identify just one 1967 Satellite Hemi convertible, making this obscure B-body an authentic muscle-car unicorn.
The Satellite Was Never Supposed To Get The Hemi In 1967
The 426 Hemi found a surprisingly natural home when Chrysler brought its race-bred monster to the streets for 1966. The Satellite sat at the top of Plymouth’s midsize B-body range, making it the logical flagship for the new engine. Plymouth built 844 Hemi Satellites that year, including 817 hardtops and 27 convertibles. Then came 1967, and Plymouth gave the B-body lineup a new king. The GTX was designed as the division’s performance showcase, pairing upscale Satellite-style appointments with a standard 375-hp 440 and optional 426 Hemi.
The Satellite was suddenly pushed out of the spotlight. The Hemi was supposed to be exclusive to the GTX in 1967, but production records indicate that a handful of non-GTX B-bodies still received it. Commonly cited figures put Hemi Satellite production at only six cars, a microscopic number beside roughly 720 Hemi GTXs built that year.
Plymouth Put A 425-HP Hemi In Its Most Unassuming B-Body
The Street Hemi may have been tamed slightly for road use, but calling it a conventional street engine would be a stretch. Beneath its cast-iron heads were a forged crankshaft, forged connecting rods and pistons, cross-bolted center main caps, huge valves, free-flowing ports, and dual four-barrel carburetors. Its solid-lifter valvetrain also meant owners had to stay on top of valve-lash adjustments, a chore that came with its race-bred personality. Factory-rated at 425 hp and 490 lb-ft, the 426 was notoriously conservative on paper, with some tests suggesting a healthy example could approach 480–500 hp.
Then came the ultimate mismatch: all that race-bred hardware sat beneath a relatively conservative Satellite body. The Satellite wore restrained styling beside the flamboyant GTX, let alone the later Hemi ‘Cuda. There were no wild graphics, stripes, bright colors, Shaker hood, or visual drama to warn bystanders what was hiding under the hood.
The Satellite Is Rarer, But The Hemi ‘Cuda Gets All The Love
When it comes to muscle car mythology, rarity carries considerable weight. Add the legendary 426 Hemi to the equation, and collectors start chasing unicorns. That’s precisely what happened with the Hemi ‘Cuda, particularly its absurdly scarce convertibles. However, while the 1967 Hemi Satellite has the scarcity, it never captured the same cultural following. In fact, plenty of enthusiasts do not even know it existed, or that so few were built.
There’s a good reason the ‘Cuda gets the spotlight, though. Its compact E-body shape, high-impact colors, aggressive graphics, and mandatory Shaker hood on Hemi cars delivered the visual drama people expect from a muscle car. The later Hemi also traded the earlier engine’s solid lifters for hydraulic valve lifters, making it somewhat more livable. More importantly, the ‘Cuda arrived near the end of the muscle-car era, giving it unbeatable last-of-an-era aura.
Collectors Still Don’t Give The Hemi Satellite The Respect It Deserves
The Hemi Satellite’s lack of recognition is not confined to car shows and enthusiast circles. Collectors haven’t exactly been lining up to give this obscure Plymouth its due, either. Its auction history makes that clear. In 2004, a remarkable 1967 Satellite Hemi convertible pilot car sold at Barrett-Jackson for $135,000. That result was impressive, but the car was also a pre-production pilot with a unique history, making it anything but an ordinary example. About a decade later, a documented, award-winning Hemi Satellite coupe reportedly brought just $117,700 at Mecum Kissimmee 2015.
Compare that with a 1970 Hemi ‘Cuda convertible that sold for $2.9 million at the same event a year later, and the disparity is impossible to ignore. That gulf says plenty about the power of reputation in the collector market. The Satellite will never carry the same instant recognition as a Hemi ‘Cuda, and it probably shouldn’t. But its extraordinary scarcity, factory-built Hemi power, and bizarre place in Plymouth history make it far more deserving of collector respect than its reputation suggests.
