Plymouth Barracuda 1973 images

By 1973, insurance surcharges, emissions rules, and new bumper regulations had already reshaped the muscle car era that once defined Plymouth’s Barracuda. The E-body soldiered on regardless, sharing its platform with the Dodge Challenger. Production numbers from this final full season tell a quieter, less celebrated story than the Hemi-powered years that usually get the attention.

There are changes for the 1973 Barracuda with the addition of the energy absorbing bumpers to meet 5 mph (8 km/h) government mandated impact regulations. The engines offered initially in ’73 are the 318 and the 340 with a high performance 360 added to the options sheet later in the year.Â All three of these engines are somewhat detuned to meet EPA requirements, and they all run fine on unleaded gasoline. There is a four speed manual transmission with a Hurst shifter available for the 240 and 360 engines only, but there were as many as three of the 318 also equipped with the four speed, either by factory error or by special order.

By 1973, the muscle car era that had defined Plymouth’s Barracuda just a few years earlier was already fading fast, squeezed by insurance surcharges, tightening emissions rules, and new federal bumper regulations that reshaped how these cars looked and drove. The Barracuda soldiered on regardless, sharing its Chrysler E-body platform with the Dodge Challenger and still offering genuine performance engines even as the broader market cooled. Production numbers from this final full season tell a story the sales brochures never did.

An E-Body in Its Final Full Season

The third-generation Barracuda, produced from 1970 through 1974, was built exclusively on Chrysler’s E-body platform alongside its Dodge Challenger sibling — a completely different design from the compact-based Barracudas that came before it. Offered only as a two-door hardtop or convertible, the E-body Barracuda represented Plymouth’s most focused pony car effort, even as the segment it competed in began shrinking around it.

Production Numbers That Tell the Real Story

For 1973, Plymouth built just 11,587 standard Barracudas alongside 10,626 of the higher-trim ‘Cuda, priced from $2,940 and $3,120 respectively — modest totals compared to the model’s late-1960s heyday. Riding on a 108-inch wheelbase and measuring 193 inches long, the 1973 Barracuda’s dimensions stayed consistent with prior E-body years, but its declining production numbers foreshadowed the nameplate’s discontinuation after just one more season in 1974.

A Lineup Trimmed Down to the Essentials

The changes for 1973 weren’t just cosmetic — the six-cylinder engine option disappeared entirely, leaving buyers with only the 318 and 340 V8s to choose from, a sign of how narrowly Plymouth had to focus its remaining resources on the cars that still sold. It’s a smaller, quieter chapter of the Barracuda story than the Hemi-powered years that get most of the attention, but it’s the chapter that shows how the muscle car era actually ended.

The Hemi Era Was Already Over Before 1973

By the time this Barracuda left the factory, Plymouth had already dropped the legendary 426 Hemi from the lineup after 1971, along with the 440 by 1972, leaving the 340 as the hottest engine buyers could still order. That progression tells the real story of 1973 better than any single spec sheet entry: it wasn’t that Plymouth built a slower car on purpose, it’s that the biggest engines simply couldn’t survive the era’s insurance surcharges and emissions requirements intact.

An Engine Bay Built for Bigger Things

The E-body platform underneath both the Barracuda and its Dodge Challenger sibling was deliberately engineered with a wider engine bay than Chrysler’s smaller compact cars, specifically so it could accommodate big-block V8s when the platform launched in 1970. That original design intent is part of why the E-body earned its performance reputation so quickly, even though by 1973 the biggest engine actually reaching showrooms was the far milder 360 mentioned on the window sticker.

From Quad Headlights to a Simpler Face

Early E-body Barracudas wore quad headlights in 1970 and 1971 before Plymouth simplified the front end to a single-headlight design for 1972 and carried it through the end of production in 1974. Spotting which headlight arrangement a given Barracuda wears is one of the fastest ways enthusiasts identify model year at a glance, and the simplified 1973 face reflects the same cost-conscious, regulation-driven direction seen in the bumpers and engine lineup that year.

A Huge Gap Between Hemi Cars and Cars Like This One

At major collector car auctions, Hemi and 440 six-pack Barracudas from 1970-71 routinely bring prices that dwarf what a 318 or 340-powered 1973 model commands, sometimes by a factor of ten or more. That gap has actually made later, milder E-body Barracudas like this one a more accessible entry point into E-body ownership for enthusiasts who want the styling and platform pedigree without competing for the handful of surviving big-block cars.

Racing Roots the Barracuda Never Fully Shed

Plymouth campaigned the E-body Barracuda in SCCA Trans-Am racing starting in 1970, fielding factory-backed AAR ‘Cuda street cars to homologate the effort, a program that ended after just a couple of seasons as manufacturer involvement in Trans-Am wound down. Even though a 1973 318 or 340 car like this one is far removed from that short-lived racing program, the association still colors how enthusiasts talk about the entire E-body Barracuda lineage today.

The Nameplate’s Final Curtain Call

Plymouth built its last Barracuda in 1974, ending a nameplate that had run continuously since 1964 across three distinct generations. The E-body’s final two years, 1973 and 1974, are often treated as a footnote by collectors chasing earlier high-performance examples, but they represent the last chapter of a genuinely important American car, built right as the entire muscle car category was being reshaped by forces well outside Plymouth’s control.

A Platform That Outlasted the Cars Built On It

Even after Chrysler ended E-body production in 1974, the platform’s reputation only grew as surviving Barracudas and Challengers became cornerstones of the broader muscle car revival that took hold among collectors decades later. A 1973 car like this one benefits from that renewed attention even though it never carried the biggest engine Chrysler offered, simply by wearing the same body and nameplate that defines the entire category for so many enthusiasts.
