This is the original prototype that would lead to the release of the Ford Mustang in 1964. The concept was far from what the Mustang would actually become, but it was the first step to creating a "legend" in the automobile industry. Unlike just about every other Mustang developed, this prototype had a mid-engine design. The small 117.6 cubic inch motor only produced 109hp. The compact design and tiny engine led the car to weigh around only 1550 pounds. That compact design came out to being only 40 inches high and 154 inches long with a 90 inch wheelbase. This certainly wasn't what we thought of just a few years later during the muscle car wars.
