The typical Thunderbirder was a front-seat dweller. Flow-through ventilation had been introduced by Mercedes on its 1954 300SL gullwing coupe, and Mercury had used the meat-ax approach to create it with its retractable backlights in 1957, but the Thunderbird's was an elegant, functional design, and was soon widely imitated.ĭesigners had created more room in the 1964 Thunderbird, but it probably didn't matter. This helped blast fresh air through the car. With a console lever, the driver could actuate a vacuum servo that opened a vent under the rear window. The 1964 roofline retained the formal air of the past, but, taking advantage of a low-pressure area behind the backlight, now featured Silent-Flo, the first windows-closed, flow-through ventilation system on an American car. Under it was a new 'deep well' trunk, which gave much more luggage space, carrying the spare tire well forward. The decklid retained the 'twin-pontoon' theme of earlier models. A lower pan, painted body color, contained the backup lights. The rear end was the best design element, set off by two oblong taillights surrounded by protective bumpers. The quad headlamps were moved to the extreme edge of the fenders, where they cut into the face of the car in canted oval cutouts. The pointed profile was still evident, but from front or rear it was completely altered.

In detail, the 1964 retained a family resemblance to the 1963 but was obviously new. The turn signals of the 1964 were intended to be sequential, but Ford ran into trouble with certain state regulations and was forced to wait a year while applying for the necessary permissions. 'And there's a cleaner, stronger rear, achieved with two of the biggest tail/turn/stop lamps ever seen on an automobile.' 'There's a more powerful look which the stylists obtained by lengthening the hood and shortening the roof lines,' said Car Life.

But a complete reskinning vastly altered them on the surface.
