Although it is based on the LaFerrari, the folks from Maranello consider the FXX K to be its own model. The XX designation is more than a car, it’s a program that enables owners to race their cars at exclusive events with full factory support. The K is for the KERS system that contributes 187 additional electrical prancing horses to the total output of well over 1,000 hp. To keep the FXX K stable, it is capable of creating more than half a ton of downforce through its active-aero systems; the coolest of which are the winglets that are joined by a rear spoiler that raises on vertical stabilizers. Is it the ultimate Ferrari? If going five seconds faster than the LaFerrari at the Fiorino test track is a measure, well… what do you think?
