Ford Thunderbird fourth generation

The fourth generation Ford Thunderbird is a large personal luxury car produced by Ford for the 1964 to 1966 model years. Ford restyled this generation of the Thunderbird in favor of a more squared-off, "formal" look. The only remnant of the Thunderbird's former sporty image was that the standard 390-cubic-inch 300 hp (224 kW) V8 engine needed nearly 11 seconds to push the heavy T-bird to 60 mph (97 km/h). The softly sprung suspension allowed considerable body lean, wallow, and float on curves and bumps. Contemporary testers felt that the Buick Riviera, Pontiac Grand Prix, and Chrysler 300K were substantially more roadworthy cars, but the Thunderbird retained its leading market share.
