Based on the historic Enzo, the Ferrari FXX was and is one of the brand's most extreme automobiles ever produced. The FXX's attitude is a race-oriented one, just like its sibling, the Maserati MC12 Corsa. In fact, customers can only drive their FXX on special track days that Ferrari approves. For one owner of the FXX, binding their driving time in their car to specific days wasn't enough. So, they made it street legal.
To give you an idea of just how powerful this road-ready FXX is, SupercarChannel92 uploaded a video of this very car (covered in tape) taking some high-speed runs at Vmax200. In the video's description, he notes that the car hits speeds of over 200 mph. See it in action by click play below.
