History of the Packard Series 2631

Unveiled in the early 1950s, the Caribbean Series 2631 marked Packard’s ambitious response to the fierce competition from Cadillac and Lincoln. Born from custom coachwork by Mitchell-Bentley in Michigan, these cars were developed as high-end personal vehicles to elevate the Packard brand. The Caribbean’s life spanned a brief but dazzling period from 1953 to 1956, throughout which it was continually re-styled and technically updated, targeting customers who sought exclusive craftsmanship and advanced technical features in a true luxury convertible or coupé. The 1956 model year symbolises the end of authentic Detroit-built luxury Packards, following Packard’s acquisition and the looming closure of its historic plant.

Model History of the Packard Caribbean Series 2631

The Caribbean Series 2631 evolved from Packard’s Cavalier models and was always positioned above the Packard 300. Early models were powered by straight-eight engines: the 1953 edition used a 327-cubic-inch inline-eight with manual gearbox. By 1954, engine capacity increased to 359 cubic inches, still following the inline-eight tradition. The biggest leap came in 1955, when Packard outfitted the Caribbean with a powerful V8 and a new torsion-level suspension system, plus the automatic Ultramatic transmission—further refined with torque converter lockup features from this point. In 1956, the Caribbean became a truly unique line within Packard, offered as both convertible and coupé, powered by a 374-cubic-inch V8 with dual four-barrel carburettors and pushbutton transmission controls. This was the final iteration before Packard's prestige models were discontinued in Detroit.

Highlights and Special Features of the Packard Series 2631

The Series 2631 is set apart by several unique and technically advanced features. Key elements include the reversible seat upholstery (leather on one side, fabric or metallic fabric on the other), lavish chrome trim, three-tone paintwork, and extensive electrical equipment such as power windows and hydraulic convertible tops. Most cars feature wire wheels and wide whitewall tyres, heightening their distinctive appearance. Beginning with the 1955 models, the innovative torsion-level self-levelling suspension became standard, offering a ride quality far ahead of many competitors. In 1956, the interior’s material quality and décor—such as gold-textured dashboard panels—remained without peer in the class.

Special Editions and Collectible Models

All Caribbean models are highly individualised, but the 1956 series especially stands out for its rarity (263 coupés and 276 convertibles built), triple-tone paintwork, and top-specification interiors. These late models represented the technical and stylistic zenith of the Caribbean line, often ordered with every available option including dual electric antennas and Continental spare tyre kits. Earlier production years—such as the 750 convertibles of 1953—are also singled out both for their scarcity and for being custom modified by Mitchell-Bentley.

Weak Spots and Common Issues

Owning a Packard Caribbean Series 2631 demands attention to its bespoke construction and specialist mechanical features. Custom Mitchell-Bentley coachwork means body panels and trim pieces may prove difficult to source should repairs be necessary. The electrical and hydraulic systems, including windows and convertible tops, require regular checking and maintenance to function reliably. The torsion-level suspension system, innovative in its day, can present challenges if neglected, particularly in bushings and linkages. The V8 engines, while robust, must be carefully maintained, with particular attention to cooling systems and carburettor tuning for optimal performance. Documentation and spare part availability may demand sourcing from specialist suppliers or reproduction parts makers.

Performance, Engine and Handling

With its robust straight-eight or powerful V8 engines, the Series 2631 offered impressive performance figures for the day—peaking at 310 hp in 1956. The three-speed manual, and later automatic Ultramatic transmission, provided effortless progress. The torsion-level suspension system, unique to senior Packards from 1955, set the car apart on rough or undulating roads, significantly improving ride and handling. Power steering and brakes came standard, giving the substantial car a refined and manageable feel. Weight is considerable, but the chassis responds well to smooth, measured inputs—a highlight on long-distance touring or boulevard cruising. - 1953 Convertible: 327 ci I8, 180 hp, only 750 built.

• 1954 Caribbean: 359 ci I8, 400 units, last inline-eight.
• 1955–56 Caribbean: V8 engines, torsion-level suspension, Ultramatic automatic, especially rare three-tone 1956 coupes and convertibles with 310 hp output.

Interior, Comfort, Exterior and Design

Styling of the Series 2631 Caribbean is audacious by any standard, with Mitchell-Bentley bodywork featuring prominent chrome work, sculpted fenders, and—by 1956—white vinyl-covered roofs. Interiors boasted reversible upholstery (1956), full-leather seating options, gold-accented trims, two-tone steering wheels, and extensive dashboard details finished in chromed and gold finishes. The wide motor hood, decorative hood scoop, and open rear wheel arches enhanced the athletic yet elegant appearance. Colour options included striking triple-tone exterior finishes from 1956. Accessories often included Wonderbar radios, dual power antennas, and whitewall tyres.

Other Noteworthy Features

Packard Caribbean Series 2631 vehicles were regularly delivered with a full set of luxury accessories—such as electric windows, power soft tops, and suite of dashboard warning lights. The large, distinctive Continental spare wheel housing at the rear was not mere decoration; it was paired with a reinforced mount and chrome trim. Specialist buyers may encounter period-optional features like chromed wire wheels and dealer-installed driving-light kits, further enhancing individual model appeal.
