1942 Chrysler Thunderbolt Concept Car

Designed by Alex Tremulis and first shown at the New York Auto Show in October, 1940. The Chrysler Thunderbolt Concept introduced a new wave of designs and industry technological accomplishments, i.e. The retractable top was so revolutionary; it would not be until 1957 before another manufacturer had a similar feature - The Ford Skyliner.
