Alex Tremulis well known for the design of the Tucker is credited to have designed the Chrysler Thunderbolt. Powered by two Rolls- Royce 12 cylinder engines, this car once treaded to a top speed of around 357mph. Fluid Drive transmission was used for power transference to the wheels that would give an extra smooth ride. The body was made from aluminum with the roof as a electrically controlled hardtop. The doors were operated by push button mechanism and the windows controlled by hydraulic power.
