1957 Ford Thunderbird: A Classic Beauty with Supercharged Power

The 1950s witnessed the rise of two iconic American cars, the Ford Thunderbird and the Chevrolet Corvette. While both boasted sporty appearances, they initially lacked the true characteristics of sports cars. Although they were built on passenger car underpinnings and carried a higher price tag, the Thunderbird distinguished itself with a touch of luxury in its sports car persona.

The Arrival of the 1955 Ford Thunderbird

Introduced in 1955, the Ford Thunderbird quickly gained popularity. In its first year, it outsold the Corvette by a significant margin, selling 16,155 units compared to the Corvette’s 700. The Thunderbird stood out with its V8 performance, elegance, and undeniable class. In 1956, minor refinements were made to the Thunderbird, and in 1957, it received a stylish fin, adding to its allure. The 1958 redesign transformed the Thunderbird into a four-seater personal luxury car, marking the end of its original concept as Ford’s Corvette competitor.

The Popular 1957 Thunderbird

Among the Thunderbird’s two-seater models, the 1957 version became the most sought-after, with 21,350 units produced. Among those, around 997 (or some sources state 1,499) were the high-performance E-code cars. These E-Birds featured the potent 312 cubic-inch overhead valve V-8 engine, equipped with dual Holley four-barrel carburetors, delivering an impressive 275 horsepower. To enhance performance, these cars had unique features like a dual air cleaner, aluminum intake manifold, modified heads and cam, and a heavy-duty Ford-O-Matic transmission. Braking was supported by power-assisted hydraulic four-wheel drums.

Distinctive Design Changes

In the 1957 model, the Thunderbird underwent some notable design changes. The designers added 6.1 inches to the length of the car, allowing them to return the spare tire to the trunk and incorporate 14-inch wheels, creating a lower riding stance. The interior received upgrades, including a new engine-turned dash, a ‘Lifeguard Design’ for enhanced safety, a padded dashboard, a dished steering wheel, and updated upholstery treatments. Additionally, engineering changes included an additional leaf in the rear springs, 14-inch wheels, and larger front brakes.

The Birth of the Supercharger Program

The year 1957 also marked the inception of the Ford Motor Company Supercharger Program, driven by NASCAR’s relaxed engine rules. The program aimed to enhance performance and maintain Ford’s reputation for powerful cars, including the Thunderbird. The project involved the production of 65 Ford Custom Two-Door Sedans, 20 Ford Convertibles, and 15 Thunderbirds, all equipped with a McCulloch VR57 Phase 1 supercharger, a heavy-duty three-speed manual transmission, seat belts, and a fiberglass hardtop.

Supercharged Thunderbird Success

One of the Phase 1 Thunderbirds set a new record for American sports cars, reaching an impressive speed of 138.755 mph. This remarkable feat surpassed the previous year’s Corvette record by 6 mph, solidifying the Thunderbird’s supercharged power and performance capabilities.

The ‘F-Birds’ for Regular Production

After proving the potential of the supercharger, Ford decided to create a milder version for regular production. A total of 194 supercharged Thunderbirds were built, known as the ‘F-Birds’ due to the letter ‘F’ in their serial numbers, denoting a supercharged engine. Although internally referred to as the ‘Phase 1 Supercharger Thunderbirds,’ the racing versions were equipped with a single-carburetor engine, earning them the popular nickname ‘D/F Bird.’ Out of the original 15 Phase 1 Thunderbirds, eight are known to exist today.

The 1957 Ford Thunderbird remains a timeless classic, combining style, luxury, and the exhilaration of supercharged power. Its unique design and racing heritage continue to captivate automotive enthusiasts, making it an enduring icon of American automotive history.
