Well prior to the 1955 Thunderbird, the closest thing to a roadster Ford offered was hot rodders were doing with '32-'34.
Chevy was two years ahead of Ford making a production 2 seat sports car. Ford has undoubtedly had some very nice styling, but the similarity in design of the T-Bird and Vette is more than obvious to me.
The T-Bird was the hottest thing on the road in that period. Chevy couldn't even get close...
But, to get back on track, let's look at the 1951 Paris Auto Show when Ford division general manager Lewis Crusoe was admiring European autos at the 1951 Paris auto show with Ford designer George Walker. "Why can't we have something like that? " Crusoe asked Walker after examining a sporty European two-seater. "Oh, but we do," the quick-witted Walked fibbed--and then telephoned Ford headquarters in Michigan and told it to get to work fast on a two-seater so Crusoe would have something to see after returning from Europe. Ford had been working on a two-seater since late 1951, but wasn't serious about it because sports cars accounted for such a tiny percentage of the U.S. market.
GM tried to make the Corvette both American and foreign--and failed on both counts. It had a hard time even giving away the first Corvettes for promotional reasons to VIPs and celebrities, many of whom disliked the car. Actually, the new Corvette wasn't all that bad despite its drawbacks, being fairly nimble and reasonably fast for its era.
The new T-Bird used a good number of regular Ford parts to hold costs down. They included headlights, taillights and instruments. The parts sharing also let Ford successfully use the 2,980-pound Thunderbird to rub off some of its sporty, glamorous image on the restyled regular Fords.
The new Thunderbird was better for 99 percent of the U.S. market than the Corvette. It could be had with options including power steering, brakes, windows and a power front bench seat designed to look like two bucket seats. (Only two adults actually fit, so the 1955-57 T-Bird always has been described as a two-seater.).
GM hated the rival Thunderbird because that Ford model was an instant success. Ford intended the T-Bird to mainly be an "image car," with annual sales of only 10,000 units. The automaker was surprised when 16,155 T-Birds were snapped up. That compared with merely 674 Corvettes produced in 1955.
The 312cu in (5.1 L) V8 became the Thunderbird's standard engine, and now produced 245 horsepower (183 kW). Other, even more powerful versions of the 312 cu in (5.1 L) V8 were available including one with two four-barrel Holley carburetors and another with a Paxton supercharger delivering 300 Horsepower....
