1955 Ford Thunderbird Facts and Specifications

General Year Information – 1955 Ford Thunderbird

Ford targeted the 1955 two-seat Thunderbird as an upscale model, personal luxury car with sporting capabilities, not as the then current thinking of a European sports car with minimal amenities. This was unlike Chevrolet, who wholeheartedly embraced that culture with the first Corvette. See:

As such, the Thunderbird not only came as a true convertible with roll up windows, power steering, and three different transmission options making it possible to turn your Thunderbird into either a luxury cruiser or a very sporty 2-seater. The result was that Ford is credited in developing a new market segment, the personal luxury car.

The result came from Ford developing, in 1952, a smaller two-seater sports roadster, named the Vega, at the behest of Henry Ford II. The completed one-off generated some interest at the time, but had meager power, European looks, and a correspondingly high cost, so it never proceeded to production. Shortly after, and in great secrecy, the design of the Thunderbird started in earnest.  The Thunderbird was similar in concept but was more American in style, more luxurious, and less sport-oriented. Ford read the market well, whereas Chevrolet did not.

The name was the result of a myriad of proposals, but a Ford stylist who had lived in the southwest submitted the Thunderbird name – a reference to the Thunderbird, a supernatural bird of great power and strength of the indigenous people.

The Ford Thunderbird was introduced in February 1953, not in response to Chevrolet’s new sports car, the Corvette, which was publicly unveiled in prototype form just a month before It was Ford’s own project, like GM, reacting to the increases affluence of the public and a greater emphasis on “free time” motoring. The Thunderbird went from idea to prototype in about a year, being unveiled to the public at the Detroit Auto Show on February 20, 1954.

Production of the Thunderbird began on September 9 of 1954, with the car available as a 1955 model on October 22, 1954. Though sharing some design characteristics with other Fords of the time such as single circular headlamps and tail lamps, and modest tail fins, the Thunderbird was sleeker in shape and featured performance cues such as a working hood scoop and a 150 MPH speedometer.

Though appearing unique, it was still Ford-like in looks so as to be recognized by the public, unlike Corvette which had no relationship to the then available 1953-54 Chevrolet. It used mechanical components from standard Ford models. The Thunderbird’s 102.0 inch wheelbase frame was a modified and shortened version used in other Fords however the engine was moved back 10.0 inches for better weight distribution. The standard 292 CID Y-block V8 was from Ford’s Mercury division was to be used.

Though inspired by and positioned directly against the Corvette, Ford advertised the Thunderbird at launch as a “personal car of distinction” and put a greater emphasis on the car’s comfort and convenience features rather than its inherent sportiness. See the 1955 Thunderbird Brochure.

The Thunderbird was a huge success, selling exceptionally well – outselling the Corvette by more than 23-to-one in 1955 with 16,155 Thunderbirds sold against 700 Corvettes.

The 292 CID Y-Block was introduced in 1955 for the Thunderbird, though it was later offered in the high-end regular Ford line. The 292 shared the 3.30 inch stroke of the standard Ford’s 272 CID V-8, but with a larger 3.75 inch bore.

There were two horsepower ratings, based purely on compression ratio – 198 HP for the AMT and 193 HP for the SMT versions.

Since the Thunderbird was aimed at a market where “comfort” outweighed “sport”, the two-seat Thunderbird was never equipped with bucket seats, thou the pattern in the seating area implied only two people should be on board. Surprisingly, the way the seat was upholstered and cushioned held drivers in place very well.


Though sold more as a personal luxury car, the times of the mid-50s were all about power and performance, so Ford made sure that the driver saw things that alluded to that. Thus, the dashboard placed a 150 MPH speedometer and a tachometer right in front of the driver. The tach placement was way ahead of the Corvette, whose tach sat off to the center of the dash well away from the driver.

There was only one model Thunderbird, a two-seat convertible coupe, with the only option as a body style was to order the fiberglass top to enclose it for inclement weather. Key in the design was a unique grille, chrome faux “louvers” on the top rear of the front fenders, and a soft top the folded down and was hidden behind the seat, giving a smooth body from the passenger compartment rearward. While the headlight bezels and the tail lights were pure 1955 Ford Fairlane, the fenders and were all Thunderbird, designed specifically for that car. Though the look is identifiable as a Ford, it was a design genius that the car was lower and more sporty than the standard  car.

It should be noted that the removable hardtop was an extra cost option.
