Designing a convertible that is as pleasant when open as it is closed is not an easy task. In 2004, Ferrari offered a unique and original solution with the 575 Superamerica based on the 575M Maranello. An electrochromic glass roof pivots 180° backwards until it rests on the flat surface of the trunk. The rear window acts as an anti-fog. This elegant system was patented by Leonardo Fioravanti, a major designer at Pininfarina from 1964 to 1986. This clever system remained as rare as the 559 examples of Ferrari 575 Superamerica built.
