Shelby EXP 500 Green Hornet
During the Mustang’s heyday, Ford and Shelby worked hard to explore the possibilities of the Mustang’s platform and engineering, producing several exciting prototypes. One of the most popular was the “Green Hornet” from 1968. It featured innovative features like a 390 V8 equipped with fuel injection, unique disc brakes, and an independent rear suspension (via SPC).
With this layout, the Green Hornet was a capable car that handled better than any other sports car. Unfortunately, the cost of producing those features was too high, so Ford and Shelby decided to go with more conventional technology. Also, the “Green Hornet” is one of the most expensive Mustangs for sale, but a $1.8 million offer wasn’t enough.
