While the first private track days around the world featuring the Ferrari LaFerrari FXX K have yet to take place, a number of examples are hitting the Fiorano circuit incredibly hard and the following example is one of them!

The following footage comes from a private test day held for LaFerrari FXX K at the Italian firm’s private race track and provides us with our best look and listen to the hardcore LaFerrari on the track so far. As you’d imagine, it sounds quite incredible and produces an exhaust note surprisingly different to both the Ferrari FXX and 599XX.


Beneath the skin, the LaFerrari FXX K features a tuned version of the LaFerrari’s 6.3-litre V12 engine and electric motor powertrain. Rather than the 950 hp delivered by the road car, the LaFerrari FXX K produces a potent 1021 hp and over 664 lb-ft of torque. Of that power, 835 hp comes from the naturally-aspirated V12 while the remaining 188 hp comes from the upgraded electric motor. Mated to this potent powertrain is a seven-speed paddle-shift dual clutch transmission.

To achieve the extra power, the V12 has been installed with new camshafts, revised intake manifolds, a redesigned valve train as well as mechanical tappets. Elsewhere, the exhaust system has been changed while the HY-KERS system now provides four different driving modes. These are Qualify Mode, Long Run, Manual Boost and Fast Charge.

While the Italian firm has yet to announce just how fast the LaFerrari FXX K is, it should hit 100 km/h in around the 2.5 second mark as well as a theoretical top speed well in excess of the 350 km/h achievable by the road car. All told, the LaFerrari FXX K is 194 mm longer and 59 mm wider than the standard car but maintains the same 1116 mm height of the road car.
