Unveiled! Ferrari presents the FXX K Evo, Maranello's most radical beast, built solely for the track

Ferrari had been working for some time on an even more radical version, if that is possible, of its LaFerrari FXX K. At last, here it is. The Ferrari FXX K EVO has rolled out of the Maranello factory to coincide with the 70th anniversary of the Italian brand.

We are talking about the most extreme version of LaFerrari, a car that is only homologated for circuit use and that brings several improvements aimed at greater aerodynamic performance.

The prancing horse manufacturer has spent more than a year testing the car in the wind tunnel, and the result obtained by Ferrari is a more radical FXX K. Ferrari claims that the Evo version of LaFerrari is up to 23% more aerodynamically efficient than the FXX K.

How does it achieve this major improvement? The new model features a fixed rear wing with several side appendages and a shark-fin shape which, together with the retractable rear spoiler, provide greater downforce. Specifically, the FXX K Evo is capable of generating 640 kg of downforce at 200 km/h and up to 830 kg at its top speed.

The Ferrari FXX K Evo produces far greater aerodynamic downforce than the base model. The flat underbody has also been redesigned and now offers larger air outlets, especially at the wheel arches. Airflow channelling is 5% more efficient in this version.

The Ferrari FXX K Evo is lighter than the standard version, largely thanks to a new carbon fibre treatment, although we do not know exactly how many kilos the car saves through this manufacturing technique.

As for the chassis, the suspension has received several damper setting adjustments, and the front brakes now have superior cooling thanks to the addition of extra air intakes.

The engine in this model remains unchanged from the FXX K version. It still offers the naturally aspirated 6.3-litre V12 engine producing 860 CV, which, thanks to a KERS system, adds an extra 190 CV. In total, the FXX K Evo delivers 1,050 CV of power and 900 Nm of torque.

The car will be produced in a series of limited units whose number Ferrari has not yet specified.
