7. Ford Cougar II Concept
In the early `60s, Ford desperately wanted something to compete with Chevrolet`s Corvette and it looked it found just the car for that task in 1963. With the help of the Italian Vignale design studio, Ford`s engineers produced a very interesting and elegant prototype called Cougar II. This car was built on Shelby Cobra chassis with 260 V8 engine but featured a closed body, more luxury, better aerodynamics, and higher top speed.
Unfortunately, Ford decided to kill the project and concentrate on Mustang and Shelby products. The downside of Cougar II was the fact that its production was more costly and it looked too much like 1963 Corvette which Ford`s top brass wanted to avoid at all costs.
