Ferrari FXX K revealed as track-only LaFerrari evolution
Ferrari has officially unveiled the FXX K, a 1,050hp track-focused development of the LaFerrari, at the Finali Mondiali event in Abu Dhabi.
Ferrari has taken the wraps off the FXX K, its most extreme development of the LaFerrari, at the Finali Mondiali event in Abu Dhabi. The new car, previously known as the LaFerrari XX during development, is a track-only machine intended for Ferrari’s most loyal customers and will not be homologated for any form of motorsport.
The FXX K’s name references its hybrid KERS (Kinetic Energy Recovery System) technology, which supplements the familiar 6.3-litre V12 with an electric motor. Combined output stands at 1,050hp, with 860hp from the combustion engine and 190hp from the electric system. This places the FXX K at the top of Ferrari’s performance hierarchy, above the standard LaFerrari.
Aerodynamic overhaul for the track
Ferrari’s engineers have made substantial changes to the bodywork to maximise downforce and stability for circuit use. The front features a twin-profile spoiler and a larger splitter, sitting 30mm lower than the standard car’s. Vertical fins and redesigned endplates channel air more efficiently along the flanks, while a higher tail section and mobile rear spoiler work together to increase rear downforce. The result, according to Ferrari, is a 50% increase in downforce compared to the road-going LaFerrari.
Other track-focused details include bespoke Pirelli slick tyres and a suite of sensors monitoring lateral, radial and longitudinal acceleration, as well as pressure and temperature. The FXX K also introduces a five-position Manettino on the steering wheel, allowing drivers to adjust the E-Diff electronic differential, Racing Side Slip Angle Control and high-performance ABS to suit circuit conditions.
Exclusivity and customer use
The FXX K is not eligible for any racing series and will be used exclusively in Ferrari’s own track programmes for selected clients. Buyers are expected to be existing Ferrari owners with a history of participation in the company’s XX development projects. Ferrari has not announced official production numbers, but previous XX cars have been built in very limited quantities.
Unlike the LaFerrari, which was designed for road and occasional track use, the FXX K will never be road legal. Its sole purpose is to provide a testbed for Ferrari’s future technologies and a platform for clients to experience the limits of the brand’s engineering. The car’s unveiling follows a series of leaks and speculation, but the official reveal confirms its position as the most advanced non-competition Ferrari to date.
