For those who don't know, the Ferrari FXX K Evo is a very rare vehicle and is unlikely to be seen on public roads.
The reason is twofold: it's not street legal, and the handful of examples in existence spent most of their time in Ferrari's care - only available to their owners at track events.
Therefore, finding one of these in action on the asphalt is an extraordinary coincidence, as you can see in MattyB727's video via YouTube.
The FXX K Evo was caught on camera taking part in one of Ferrari's Racing Days, almost a year ago at the Mugello Circuit.
We've embedded the video at the top of this page for you to enjoy.
However, we recommend wearing the best headphones because the car produces a brutal sound that is a treat for the ears, screaming up to 9,200 rpm on the Italian track.
The LaFerrari-based supercar was introduced in 2017 as an aerodynamic package for 40 standard 2014 Ferrari FXX K units or as a very limited stand-alone model.
Ferrari, however, did not reveal how many units it would make.
The sample seen at Mugello earlier wore the number 59 and was driven by Danish racer Peter Christensen.
