2. Dodge Charger III
The success of the Charger-inspired the Chrysler designers to develop the idea of a Dodge performance model. The original Charger had power, performance, and countless racing wins. But it was still a big, heavy, and non-aerodynamic muscle machine. However, the 1968 Charger III concept was something quite different. The Charger III was no longer a muscle car, but a pure two-seater sports machine. It had compact dimensions, a low profile, a low weight, and several unusual features.

For example, instead of conventional doors, the whole top of the car opened to allow access to the interior. Also, the steering column tilted along with the steering wheel to make entry more comfortable. On the back of the car, there were massive airbrakes. In fact, they were similar to the ones on airplanes that deploy under heavy braking. Unfortunately, since the whole car was extremely futuristic, it was doomed from real production.
