The new design lines introduced by Ford were not recieved with indifference by other car brands.Such was the case of General Motors, that immediately answered by creating the Firebird. This car was truly innovative and, unashamedly inspired by aeronautics and space travel. Unlike many of Ford's proposals, that didn't go from drawings to reality, General Motors actually built various prototypes.
The first prototype to be produced was the Firebird I, in 1954. It was evidently and deliberately similar to an airplane, but the design is too primary. Besides, it had a limited use: it had only space for a driver, lack of space for the luggagem etc. - it wasn't an automobile yet.
The concept's evolution led to the Firebird II, possibly the most interesting of the series and a true family automobile. The innovations were staggering. The vehicle was powered by a potent gas turbine and controlled by a joystick, just like an airplane. It also had directional sensors, a radar and a camera. Don't forget we were only in 1956...
Two years later, the third evolution would arrive, the Firebird III, much less interesting than its predecessor. It was the final version of this fabulous car. After this endeavour in futuristic cars, GM turned to more conventional vehicles.
