Ferrari’s “XX” program has given birth to some of the most incredible performance Ferraris we’ve seen this millennium. The project began back in the early 2000s with the Ferrari FXX, a high-performance racer that was based on the Enzo. Production of the FXX began in 2005 and in the course of its life, 30 models were produced, each packing 789 horsepower and 506 pound-feet of torque from its massive 6.3-liter V-12 engine. Despite the limited quantities and the difficulties in owning one, the FXX became such a popular car that Ferrari followed it up with the even more exclusive, 850-horsepower FXX Evoluzione. To this day, the FXX Evoluzione is still considered the fastest car Ferrari has ever released, thanks in part to its 250 mph top speed.
