The E-Type Jaguar is rolling art. If you have doubts about that, just remember that Enzo Ferrari, the spirtual father of more masterpieces than any other, called the E-Type "The most beautiful car ever made". That may be the mother of all endorsements. It was the first car to appear in the New York Museum of Modern Art.
So is it possible to improve upon what some see as perfection? In 1962, shortly after the introduction of the E-Type, Jaguar management wanted to explore the possibility of building a car in the spirit of the D-Type racer but with elements of the E-Type's styling and design.
