Market research suggested sales of the Thunderbird were limited by its two-seat configuration, making it unsuitable for families. Īlong with the 1958 Lincolns, the 1958 Thunderbird was the first Ford Motor Company vehicle designed with unibody construction.Īlthough the 1955-1957 Ford Thunderbird had proved successful (in comparison to the Chevrolet Corvette), Ford executives-particularly Robert McNamara-still felt its overall sales volume had room to improve. Sales totalled 198,191 over three model years, approximately four times that of the earlier two seat model. In response to Ford-conducted surveys two major changes were made to attract potential buyers: two rear seats were added and the level of luxury and features of a full-sized car were incorporated into a mid-size platform.Īs a result, sales soared and the new model dramatically expanded the personal luxury car market, winning the Motor Trend Car of the Year in 1958. The second generation Ford Thunderbird (also called Square Bird ) was produced by Ford for the 1958 to 1960 model years as a successor to the popular 1955–1957 two-seater.
