The 'XX' race-spec variant of Ferrari's most powerful machine has been unveiled. And we want it.
It will never be driven on the road. And it will never be used in competition. So in creating the just-unveiled track-only experimental LaFerrari-based Ferrari FXX K, Maranello wasn’t restricted by racing regulations or homologation. The laboratory-car is therefore utterly uncompromising, packing cutting-edge technology and offering an otherworldly driving experience just a handful of people will ever get the chance of having.
Ferrari says the FXX K (‘K’ referencing the car’s ‘KERS’ kinetic energy recovery system) boasts a total output of 1,036 hp from what is essentially the same drivetrain as the 935-hp LaFerrari. 848 hp comes from the 6.3-liter naturally aspirated V12 and 187 hp from the electric motor. Torque is said to be "over 664 lb-ft." New camshafts, modified valve trains, redesigned intake manifolds, and reworked exhaust system whose silencers have been 'eliminated' are the main changes Ferrari has made to the internal combustion engine. The car body has also been extensively reworked to improve both active and passive aerodynamics.
Up front, a twin-profile spoiler and larger splitter sits 30 mm lower with a gap in the center and vertical fins that sends air over the flanks. A monster diffuser sits at the rear optimizing air extraction from the underbody, while the tail section is now higher and mobile spoiler extended further. The most obvious visual change is the vertical fin and small wing on each end of the tail. These act as guide vanes when the rear spoiler is retracted and boosts the spoiler’s efficiency in 'high downforce' mode. The result of all these changes is 50 percent more downforce than the LaFerrari with the FXX K generating 540 kg at 124 mph.
Pirelli slicks on the FXX K come complete with sensors monitoring acceleration, temperature and pressure, helping the traction control system to do its job better. Expect the LaFerrari’s 2.9-second 0-62 mph time to be seriously improved upon. A five-position Manettino button on the steering wheel controls the E-Diff electronic differential, F1-Trac traction control, Racing SSC and high-performance ABS. In regards the HY-KERS, a 4-setting Manettino on the center console allows the driver to select Quality (for maximum performance), Long Run, Manual Boost and Fast Charge. To buy one of the 30 or so models slated for production, you’ll probably need around $3 million.
