The Chrysler Thunderbolt concept car was a groundbreaking design in the 1950s. It was constructed with aluminum and showcased a retractable, electrically operated hardtop roof, along with hidden headlights and enclosed wheel wells without A-pillars.

The two-seater had leather upholstery and was powered by a 323.5 cubic-inch straight-eight engine, which could generate 143 horsepower. The engine’s power was transmitted to the rear wheels using a Chrysler Fluid Drive transmission. Out of the original five Thunderbolts produced, four are still in existence, one of which is on display at the Walter P. Chrysler Museum in Auburn Hills, Michigan. Each of the five cars was painted in a distinctive color scheme.
