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.

When the FXX program was shelved in 2009, Ferrari turned its attention to its successor, the 599XX. Based on the Ferrari 599 GTB Fiorano, the 599XX followed the same blueprint as its predecessor. It was designed strictly for track use and was developed with pure and unadulterated performance in mind. As a result, the 599XX came with a 6.0-liter V-12 engine that produced in excess of 720 horsepower, accelerating at a breathless 9,000 rpm. And just like the FXX, the 599XX was quickly followed by the 599XX Evolution, a lighter and radically re-styled version that also had more power (740 horsepower) than its “standard” counterpart. The 599XX and the 599XX Evoluzione may not have been as quick as the FXXs, but these models featured the latest in automotive technology at the time, something it’s own successor, the FXX K, can proudly say as well.

For all intents and purposes, the Ferrari FXX K is the incumbent standard-bearer of the XX program. It’s based on the LaFerrari, which means that it also has a hybrid engine that produces a staggering 1,050 horsepower, 848 of which come from the hypercar’s 6.3-liter V-12 and the extra 187 ponies coming by way of an electric motor. It’s by far the most powerful of all the track-only XX Ferraris, although by account of its hybrid engine, it’s also somewhat muted compared to the ear-splitting shrieks its two predecessors routinely produce.

No more was that evident than during the recently-held Ferrari World Finals at the Mugello circuit. In about as rare an occurrence as you can find, all the Ferraris under the XX program paraded around the track in a show of force the likes of which none of us will see anywhere else. The video is over six minutes long and is best viewed with the volume in full blast.
