Most people will remember Alex Tremulis as the legendary designer of the Tucker, but for Imperial fans, we remember him as the designer of the remarkable 1940/'41 Chrysler Thunderbolt because the design was based on a 1940 Chrysler Crown Imperial frame. Tremulis, who had been working with Crosley and American Bantam in the late 30's, returned to Briggs Body Works to create this fantastic concept car for Chrysler. Tremulis worked with Ralph Roberts on the design.
As with the Newport Phaetons, five of these wonderful show car were built for Chrysler. It was dubbed "The Car of the Future" and was an aluminum envelope-bodied, flush-fendered coupe with a fully retractable, electrically controlled hardtop. Pushbuttons operated the doors (there were no door "handles") and it even sported hydraulic power windows. The totally enclosed front and rear wheel wells was also a new design concept.
Tremulis' new concept car was also marked by a discrete silvery bolt of lightning on each smooth door. The electrically-controlled top could be concealed beneath the rear deck of the two-seater by pressing a button. Concealed headlights, anodized aluminum trim at the base of the car's body and leather interior trim marked this sleek full-fender look. It was powered by a 143-HP straight eight engine.
Today, there are 4 known Thunderbolts still surviving. One of them is on display at the Walter P. Chrysler museum in Auburn Hills, Michigan. Each Thunderbolt was manufactured with a unique color scheme and no two were alike.
