Ferrari has just taken the wraps off the track-only LaFerrari FXX K designed to be even faster around a circuit than the road-going LaFerrari with it joining the Ferrari FXX and 599XX in the exclusive Ferrari XX programme.
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.
Qualify Mode provides the maximum performance for a limited number of laps, Long Run is designed for longer stints on the track, Manual Boost provides maximum torque instantly while Fast Charge charges the car’s battery.
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.
From an aerodynamic standpoint, the FXX K features a plethora of important changes differentiating it from the ‘regular’ LaFerrari. The front fascia for example has been completely remodelled with the headlights ditched, a new hood fitted as well as a prominent splitter which extends 30 mm further out than the standard one.
Elsewhere, the LaFerrari FXX K features enlarged side sills while at the rear, the aerodynamic changes become even more apparent. A larger movable rear wing/air brake has been installed alongside two prominent, fixed fins on either side. Additionally, new exhausts have been fitted alongside an ultra-aggressive rear diffuser to suck the track-car to the tarmac. When it is all said and done, the FXX K produces 50 per cent more downforce than the road car resulting in 540 kg of downforce at 200 km/h.
As for the tyres used, they are Pirelli P-Zeros and feature sensors which measure acceleration, temperature and pressure. Additionally, the traction control, Side Slip Angle Control and electronic differential have been modified for the new tyres with a selection of ABS settings available on the steering wheel. Braking is performed by specially designed Brembos.
In the cabin, the LaFerrari FXX K is even more stripped out than the road car with it featuring body-hugging race seats as well as a new instrument panel and steering wheel.
It remains unclear just how much the LaFerrari FXX K will cost nor how many examples will be produced.
