1954 Hudson Hornet: The Last Step-Down Year, Built Into the Formation of AMC
The last step-down Hornet: a restyled body, a 160-hp base six, Twin-H and 7-X options, and a production end in October 1954 as Hudson merged into American Motors.
United States · researched through 2026-09-23
1954 was the last year for the step-down Hornet body, and the model year closed against a corporate backdrop bigger than any styling change: the Nash-Kelvinator merger that created American Motors was approved on January 14, 1954, while Hudson kept building Hornets on its own until October 30, 1954. Both the Hudson-Essex-Terraplane Club's compilation and Old Cars Weekly agree on 24,833 Hornets built for the year, though the two figures share the same Standard Catalog lineage rather than serving as independent confirmations of each other.1,2
The 308-cubic-inch six now spanned three states of tune: 160 horsepower at 3,800 rpm standard with the aluminum cylinder head and 7.5:1 compression, 170 horsepower with the $86 Twin H-Power dual-carburetor option, and 210 horsepower from the $385 7-X package, sold through Hudson's parts operation rather than as an ordinary factory option. A lower-priced Hornet Special series, 6D, arrived on March 19, 1954, running $115 to $140 below comparable full Hornets with the same Hornet engine but less brightwork, in four-door sedan, club sedan, and club coupe bodies; whether those Hornet Special cars sit inside the 24,833 total is not stated outright, though the club table's own serial examples for the Hornet column start including 6D cars from March 1954 onward, suggesting they do.2,1
Two separate figures disagree between Old Cars Weekly and Hudson's own 1954 brochure. The bore for the 308 six is given as 3-15/16 inches by Old Cars Weekly's specification block, but Hudson's own 1951 through 1953 price folders for the same displacement all state 3-13/16 inches, the figure this record treats as consistent with the stated 308-cubic-inch displacement even though no 1954-specific factory bore figure was found to confirm it directly. Overall length shows a starker gap: Old Cars Weekly gives 268-7/8 inches, roughly five feet longer than the 208-15/32 inches Hudson's own full-line brochure states, a difference large enough that the record treats the Old Cars Weekly figure as a probable typographical error and uses the factory brochure's number instead.2,3
On the track, Hudson closed out the step-down era with 17 wins in 36 NASCAR Grand National races and a third consecutive manufacturers' title, while Herb Thomas repeated as Southern 500 winner. Production ran unevenly through the model year, dipping to a low of 671 cars in February 1954 before climbing back to its highest single month, 3,001 cars, in October 1954, the very month the last step-down Hornet was built. The club table's approximate body counts show 244 Convertible Broughams and, marked with its own question mark, 1,263 Hollywood hardtops, both figures the source itself flags as uncertain rather than firm.2,4,1
Pricing bracketed the 1954 line from the value-oriented Hornet Special, whose club sedan started at $2,571, up to the Convertible Brougham at $3,288, a roughly $717 spread across the year's body styles. Hudson dressed the Hollywood hardtop specifically with tri-color, no-extra-cost seat and headlining combinations in antique white Plasti-hide with red, blue, or green bolsters, while the Convertible Brougham offered genuine leather in blue, maroon, or green with Plasti-hide side trim, a reminder that even in its final step-down year Hudson kept differentiating its Hornet body styles by trim as much as by mechanical content.2

Every figure is labeled with how sure we are. Reported means a manufacturer, registry, or reference figure we cite but have not reconciled against factory records ourselves. Disputed means credible sources disagree and both are shown. Rows are separately scoped; don't add them together unless the note says they make up a total.

| Hornet Convertible Brougham (approximate)1 Hornet (7D) · Convertible Brougham · all production The club table marks its convertible and Hollywood counts as approximate and states no method. | 244 | built, model-year | Estimate |

No firm body-style, engine or transmission split was found in an accessible source; the only body rows are the club table's approximate convertible and Hollywood counts. The 11,603 Wasp figure belongs to a different series and is not a Hornet row.
The calendar-month rows are the club table's monthly build counts for its HORNET column, August 1953 through October 1954; they sum to the 24,833 total. That column's example serial numbers include 6D (Hornet Special) cars from March 1954 on, so the total appears to include Hornet Specials, although the table does not say so in words.
The Hornet Special (series 6D) was introduced on 19 March 1954 in three bodies (four-door sedan, two-door club sedan, club coupe); no separate Hornet Special production figure was found.

Where the sources disagree
Hornet 308 bore

- 3-13/16 in bore x 4-1/2 in stroke (Hudson's 1951, 1952 and 1953 price folders for the same 308 engine)3
No 1954 factory bore figure was found. The factory 3-13/16 in bore is the one consistent with the stated 308 cu in displacement; the page shows both and does not publish a 1954 bore as fact.
