The Chrysler Thunderbolt Concept introduced a new wave of designs and industry technological accomplishments. The body was comprised of aluminum and the roof was a retractable, electrically controlled hardtop. The design was courtesy of Alex Tremulis, an individual who introduced many inspirational industry designs such as the Tucker. Based on the Chrysler Crown Imperial and named after Captain George Eyston’s land speed record accomplishments, the Thunderbolt was a masterpiece. Eyston had captured the Land Speed record in 1938 at the Bonneville Salt Flats by traveling at a speed of 357.53 mph. Using a specially designed vehicle that was over 30 feet in length and weight an astonishing seven tons, it was powered by two Rolls-Royce 12-cylinder engines.
