Buyers could select either a manual folding disappearing soft-top, or a removable fiberglass hardtop painted to match the body color of the car. In a few rare cases, both tops could be ordered. By the end of the first 13-month selling season for the Thunderbird, a total of 16,155 had been produced.
Featuring only a few minor styling up-grades, but plenty of new features, the 1956 Thunderbird went on sale in early November 1955. Under the hood, an enlarged V8 engine was optionally available, sporting 312 cubic inches and rated at 215 horses when backed with the manual or overdrive transmissions, or 225 hp when the Ford-O-Matic was installed. Also new was the switch to 12-volt negative ground electrics, another improvement that Ford had lagged behind some of the competition with. In the Spring of 1956, a dealer installed dual four-barrel intake option was released, which boosted output to 245 horses.
Other touches included a revised front grille, taillights and interior appointments, but the biggest difference for the 1956 Thunderbird was the rear bumper mounted Sport-Tire Carrier, or continental kit. Some liked it, some didn't, but it certainly didn't help the already soft-handling 'Bird. Refinements included opening air vents in the front fenders to help ventilate the passenger compartments and the introduction of "porthole" style windows to the detachable hardtop, which helped rearward lateral vision somewhat. Also growing was the selection of exterior colors which grew to nine including Raven Black, Colonial White, Fiesta Red, Buckskin Tan, Sunset Coral, Goldenglow Yellow, Thunderbird Green, Thunderbird Gray metallic, and Peacock Blue.
Technically, the 1956 model year for Thunderbird was only eleven months long, which helps to explain the drop in production totals to 15,631. Another explanation was the hefty price increase, to $3,151.
For its third year, the Thunderbird received an attractive updating that kept its styling theme in line with the full-size models. A wide open-mouth styled front grill was used filled with a chrome plated squared mesh, and starting in the center of a doors, a fashionable pair of fins topped the rear quarter panels. The spare tire moved back into the trunk and an attractive rear-bumper finished off the styling.
Inside the passenger compartment a redesigned instrument cluster and new convenience options included two versions of power seats, four-way and Memory-Matic, which would roll back and down whenever the car was turned off, and would return to a pre-set location when the car was restarted. While the addition of fun little extras is fodder for car buffs of today, the real news for the 1957 Thunderbird was under the hood. Included in the new base price of $3,408 was the Thunderbird 292 cid V8, which could only be ordered with the manual three-speed transmission. With either the overdrive or the Ford-O-Matic, the single four-barrel 312 cid V8 was on tap. Two very special engines were offered for the 1957 Thunderbird, the "E-code" 312 cid V8, which belted out 270 horses and for those looking for a truly "hair-raising" experience, there was the supercharged "F-code" Thunderbird engine, which sported 300 horses.
To clear up a little confusion, the terms E-code and F-code refer to the letter at the start of the identification number which signifies the engine installed at the factory. For 1957, the base 292 cid V8 carried the letter "C", while the very popular 312 cid V8 with a single four-barrel carburetor was identified by the letter "D" at the start in the VIN. "E" represented the dual four-barrel set-up while "F" was for the supercharged edition. According to surviving production records, it has been found that only 212 of the 21,380 Thunderbird built for the 1957 model year were equipped with the "F-code" engine.
A very wide selection of colors was offered for the 1957 T-bird customer to choose from, and while single-tone editions were quite popular, a number of these were done in a two-tone combination with the removable hardtop receiving the contrasting hue. This was also the most popular model year for the Thunderbird due in part to the acceptance by its customers and in part to its 15-month model year. Ford planned to replace the two-seater with totally new
