United States · researched through 2026-09-23
This record's own overview describes the 1964 Gran Turismo Hawk as changing little from the year before: the most visible updates were a redesigned deck lid and an optional half-covered vinyl top, which Old Cars Weekly names the Sports Roof and prices at $65, while the high-performance Avanti-derived engines carried over unchanged. Production of the Hawk, and of Studebakers generally in South Bend, ended on 20 December 1963 when the plant there closed, making this the final Gran Turismo Hawk model year.1,2
The museum and 1956goldenhawk.com agree on an all-market total of 1,767 Gran Turismo Hawks at a base price of $2,958, a price this record's own key facts note as lower than the $3,095 carried in this same record's prior comparison. Old Cars Weekly's domestic figure of 1,484 matches the domestic column of a separate tertiary sales table exactly, and that table's paired export figure of 283 sums with the domestic count to the museum's own 1,767 total precisely, leaving no unreconciled gap in the production figures for the year. Old Cars Weekly separately reports that only 44 full-package R2 Hawks were manufactured in 1964, but this record's own production note flags that the museum instead attaches that same 44-unit figure to 1963 Super Hawks in its own collection description, an unresolved attribution this record carries without picking a side.1,3,2,4
The standard 289 two-barrel is rated 210 hp, rising to 225 hp with the four-barrel; the optional R1 is rated 240 hp; the optional supercharged R2 is rated 289 hp by one Old Cars Weekly article, though this record's own engine note flags that a second Old Cars Weekly article on the very same GT Hawk instead gives 290 hp, an internal inconsistency within that single publication. A supercharged R3 at 304.5 cu in is listed at 335 hp, and a twin-four-barrel R4 at the same displacement is listed at 280 hp, though this record's own conflict entry notes the museum's footnote instead implies 290 hp for the R4 by its stated increment over the 210-hp base. The museum's footnote separately states a 304.5 V8 was offered on paper but that no production examples were actually built. Three transmissions are documented: a three-speed manual standard, the Flightomatic automatic optional, and a four-speed manual with floor shift optional.2,1
Factory sales literature for 1964 advertised the R1, described there as a 10:1-compression four-barrel engine with dual exhaust, a 35-amp alternator, and a viscous fan, as an option across all 1964 Studebaker models, and advertised the 9:1 four-barrel supercharged R2 the same way as a performance option fleet-wide; the R3 and R4 were special-order only by contrast. The interior gained a painted-dot headliner, silver-threaded upholstery, and a redesigned instrument cluster. Nine 1964-specific exterior colors are charted, six of them iridescent finishes; nine Gran Turismo Hawk-specific trim codes are documented, four cloth colors and five vinyl colors.2,5
1964 Hawk engines carry no simple running serial number; instead each is stamped with an alphanumeric code combining a prefix for its type, P for the base 289, JT for R1, JTS for R2, or R3 or R4 directly, with a C added for Canadian-built units, followed by a month letter, the single year digit 4, and the day, with additional leading digits marking an export-built engine. Model codes are given as 64V-K6 and 64S-K6, the six-cylinder 64S-K6 scoped to export markets only. This record's own key facts also note that total Hawk production across the model's entire run is given as 79,615 by one source, covering 25 October 1955 through the 20 December 1963 closure, against the museum's own rounder 'just over 80,000,' a gap this record does not resolve. The Gran Turismo Hawk held its 120.5-inch wheelbase and 204-inch length to the end; shipping weight is given as 3,230 lb by one source and 3,280 lb by another, with neither weighing basis stated.6,3,1,2

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.

- Engine numbers
- 1964 Hawk engines carry no running serial. They are stamped with an alphanumeric code: prefix P (289), JT (R1), JTS (R2), R3 or R4 (with C for Canada), then a month letter, a year digit (4) and the day. Additional leading digits mark an export engine.6
- Model codes
- 64V-K6 and 64S-K6 as listed.3
- Factory build record
- The Studebaker National Museum holds factory Production Orders for most 1936-1966 Studebakers; these are the check for any R-engine or package claim.8
- Body codes and plate
- 64S-K6 GT Hawk six hardtop (169.6 cu in), export only; 64V-K6 GT Hawk V8 hardtop (259 or 289). Body plate riveted to the cowl under the hood.9,5
