2005 Ferrari SuperAmerica rear.jpg

When you're Ferrari, making your car special doesn't need to mean making it faster. So for Ferrari's new SuperAmerica, the company took the none-too-slow, V12, 540-horsepower 575 Maranello and reinvented the roof. It's a convertible all right, but this one has a glass panel that flips up backward, trap-door style, in ten seconds. When closed, the roof features advanced electrochromic glass that lets the driver choose between five levels of tint. One touch of a button can drop it from its highest to lowest setting in under a minute.
