This seldom happens in the new car biz, but check this out: With the 1958-60 Ford Thunderbird, sales actually rose each year over the car’s three-year product cycle. The Squarebird, as enthusiasts call the second-generation Thunderbird today, sold almost 38,000 units in 1958, nearly doubling the volume of the original two-seat ’55-’57 Thunderbird—which had been a sensation everywhere but in the showrooms. From there, sales continued to climb in in 1959 to 67,000, and then blew past the 90,000-unit mark in 1960.
Far more often, the opposite occurs: Sales tend to be strongest early in the cycle, then trail off as the limited market demand is satisfied. But in this instance the Ford product and marketing team was really onto something. With the four-passenger Squarebird, essentially they had invented a new vehicle category: the personal luxury car.
Meanwhile, the Ford guys would stop by the GM display with their tape measures and carefully inspect the sporty touring cars. When the four-place Thunderbird was rolled out in February of 1958, Mitchell knew GM had missed its opportunity. “By God, out comes the Thunderbird,” Mitchell remembered. “Oh, [they] caught us, and we didn’t have a four-passenger, and that thing took off.”
In other ways the T-Bird was a fairly conventional Motor City offering, though it was the first Fomoco product (along with the ’58 Lincoln) to employ unit construction. The 113-inch wheelbase chassis and squared-off styling by Bill Boyer remained virtually unchanged over the three-year product cycle, as the grille and side trim received very minor tweaks each season, and for 1960 the four tail lamps were replaced by six. And the sales continued to climb.
With the Squarebird, Ford general manager Robert McNamara and crew had shrewdly identified both the original T-Bird’s most endearing feature, its sporty, youthful character, and its greatest handicap in sales volume, the lack of a rear seat. Ford continued to mine the personal luxury category over the next four decades with eight more generations of four-and-five-place Thunderbirds, then finally returned to the original two-seater theme with the 2002 Retro-‘Bird.
