Seven gears via paddle shifts and an eight-liter, W-16 engine push the Vitesse from 0 to 250 mph in just 55 seconds, easily making it the world’s fastest convertible. And massive carbon-ceramic brakes stop the thing even faster; it can decelerate from 250 mph to a dead stop in around 10 seconds, providing a negative G force to the driver that's absolutely frightening. In short, this sleek beauty, which retails for $2.5 million, can also be a monster. It all depends on how you treat it.
