Overview

Studillac was the name applied to a short-lived American custom automobile conversion created by Bill Frick Motors in Rockville Centre, New York. Produced during approximately 1953–1955, the car combined the body and chassis of a Studebaker Starliner hardtop coupe with a Cadillac overhead-valve V8 engine. The concept addressed a characteristic concern of the early postwar American performance market: attractive or innovative car bodies were not always matched by the strongest available powertrains. Studebaker’s streamlined Starliner styling was regarded as distinctive, while Cadillac supplied a powerful and well-regarded V8 engine. The resulting hybrid offered a high-performance alternative without the price and exclusivity associated with imported sports and grand-touring cars. Bill Frick Motors offered the work both as a conversion for a customer-supplied or existing Studebaker and as a complete automobile. Contemporary descriptions identify Cadillac V8 outputs in the approximately 210–250 horsepower range, depending on the engine configuration. Buyers could choose between a manual three-speed transmission and an automatic installation, with a dual-range Hydra-Matic listed as an option. The conversion price was reported at roughly $1,500–$1,795, while a complete Studillac cost about $4,500–$5,000. These figures reflect period pricing and should not be treated as current or directly comparable without historical context. The Studillac’s appeal extended beyond its engine transplant. Available or advertised equipment included leather upholstery, wire wheels in bolt-on or Borrani knock-off forms, and an electric tachometer. The car also received upgraded drum brakes, an important modification given the performance increase over the standard Studebaker installation. Reported performance was approximately 125–130 mph at maximum speed and 0–60 mph in about 8.5 seconds. Those figures made the Studillac an unusually rapid American custom car for its era, although its braking and finish remained different from the standards of more expensive European grand-tourers. The model was not a mass-market product or a conventional automobile manufacturer’s series. It was a specialist conversion associated with one custom-car business, and its limited production period appears to have ended by the middle of the 1950s. Its importance rests on the way it combined American styling, American V8 power, and specialist coachbuilding or aftermarket practice before engine swaps became a more broadly recognized performance-car formula. The Studillac also acquired cultural visibility through Ian Fleming’s James Bond novels. Felix Leiter, Bond’s American friend and a fictional CIA agent, is described as owning a black Studillac in Diamonds Are Forever and Goldfinger. Fleming had reportedly driven one himself while visiting the United States, which helped connect the obscure custom car with the popular image of postwar American speed and sophistication. The literary references are part of the Studillac’s legacy rather than evidence of a continuing commercial brand. No current operating company, official website, public listing, or active product range is identified in the supplied reference material.

History

Studillac emerged in the early 1950s from the American custom-car trade rather than from a large automobile manufacturer. Bill Frick Motors, based in Rockville Centre, New York, developed a conversion using the hardtop body of the Studebaker Starliner coupe and replacing its original powertrain with a Cadillac overhead-valve V8. The name itself combined the identities of the two principal donor marques: Studebaker supplied the car’s body and basic platform, while Cadillac supplied the engine. The project reflected the competitive performance environment of the period. American manufacturers were increasing engine capacity and power, but independent or smaller automakers did not always have access to the same range of high-output powertrains as General Motors’ Cadillac division. Studebaker’s Starliner was notable for its streamlined styling, and a Cadillac V8 provided a way to create a faster and more prestigious version without designing an entirely new automobile. The result was a specialist hybrid sold through a custom-car business. The conversion was offered in more than one form. Customers could reportedly pay for the installation work, with prices varying according to transmission choice, or purchase a complete car. A manual three-speed arrangement was available, while an automatic option and a dual-range Hydra-Matic were also identified. Other equipment included leather, wire wheels, and an electric tachometer. The modifications were not limited to engine installation: upgraded drum brakes were fitted to help manage the additional performance. Period performance descriptions placed the Studillac’s top speed in the range of 125–130 miles per hour and its acceleration from zero to 60 miles per hour at approximately 8.5 seconds. This made it a notable performer among American cars of the early 1950s. Its pricing was also presented as a value proposition when compared with later and much more expensive European cars such as the Aston Martin DB4. The comparison was not an assertion that the two cars were equivalent in engineering or finish. The DB4 had superior braking technology and a higher level of fit and finish, while the Studillac’s attraction lay in its combination of speed, individuality, and comparatively moderate American custom-car pricing. The known production window is generally given as 1953–1955. The Studillac does not appear to have developed into a long-running marque with a standardized dealer network, broad model range, or continuing corporate identity. It is better understood as a limited-period conversion and a notable example of postwar American hot-rodding and specialty-car construction. As with many low-volume customs, exact production totals and a complete surviving-car registry are not established by the supplied sources. The car’s later reputation was strengthened by literary association. Ian Fleming included a black Studillac as Felix Leiter’s automobile in Diamonds Are Forever and Goldfinger. Fleming was also reported to have driven a Studillac during a visit to the United States. These appearances gave the obscure vehicle a place in James Bond-related automotive culture and helped preserve its name after production ended. The Studillac is therefore remembered both for its mechanical specification and for its role as a literary symbol of American postwar automotive performance.

    Studillac conversion

    The core Studillac offering was a specialist conversion of a Studebaker Starliner hardtop coupe. Bill Frick Motors installed a Cadillac overhead-valve V8, with cited outputs ranging from approximately 210 to 250 horsepower depending on configuration. The package could include transmission changes, upgraded drum brakes, luxury trim, wire wheels, and an electric tachometer. It was sold as conversion work and was also available in complete-car form. Reported performance was approximately 125–130 mph with 0–60 mph acceleration in about 8.5 seconds.

    Complete Studillac automobile

    In addition to conversion work, Bill Frick Motors offered complete Studillac cars. These vehicles retained the distinctive Studebaker Starliner body while receiving Cadillac V8 power and selected custom equipment. Reported complete-car pricing was approximately $4,500–$5,000 during the period, while conversion-only pricing was lower and varied with transmission choice. The complete automobile was a limited-production custom rather than a regular-volume model from Studebaker or Cadillac.
