6. Shelby EXP 500 “Green Hornet”
During the Mustang`s heyday, Ford and Shelby worked hard to explore the possibilities and limits of the Mustang`s platform and engineering and produced several interesting prototypes. One of the most popular is the “Green Hornet” from 1968.
Although it wasn`t the only car, the Green Hornet featured the most innovative features like 390 V8 equipped with fuel injection, unique disc brakes on all four wheels, and independent rear suspension. With this layout, the Green Hornet was a very capable car that handled and stopped better than any other sports car on the market. Unfortunately, the cost of producing those features was too big and Ford and Shelby decided to go with more conventional technology.
