Ferrari Debuts its Track-Only LaFerrari, the FXX K

After plenty of rumors and denials, Ferrari did finally fess up to the development of the track-only version — XX in Ferrari speak — of the LaFerrari. Following that confirmation, details began leaking and even more spy shots started popping up, but now we have the real deal as Ferrari has revealed the preliminary details and photos of its track-only, LaFerrari-based FXX K.

The first thing that stands out is its name, as the “K” is traditionally not a part of the XX naming scheme. Ferrari included the “K” at the end of the name to reference the Kinetic Energy Recovery System (KERS) that this race car uses. The use of KERS immediately disqualifies it from any FIA-sanctioned racing, but that doesn’t matter to those who buy this rig, as Ferrari ensures an “unprecedented driving experience” to a very exclusive group of buyers. A few days a year on a private track is likely all the reason a mega-wealthy buyer would need to shell out the millions that this car will require.

The FXX K is obviously based on the LaFerrari hybrid supercar, but it features a slew of distinct modifications. Up front you’ll notice a twin-profile spoiler and a larger splitter that it 30 mm lower than on the standard LaFerrari. This system uses two vertical elements, an endplate, a dive plane, and vertical fins to usher air toward to car’s flanks to help direct the wake created from the wheel wells around the body. A set of modified side skirts help eliminate some of the underbody lift too. Out back there is a rather unique active spoiler that is extends 60 mm further than on the base LaFerrari. Also unique are the two smaller wings (the parts that look like an unfinished spoiler) flanking this spoiler, which act as guide vanes for the airflow and increase the effectiveness of the active spoiler. There is also a modified diffuser to help clean up the undercar airflow and an optimized flat underbody.

All of the aero work amounts to an insane amount of downforce. In its low-drag configuration, the FXX K creates 50-percent more downforce than the base LaFerri in the same configuration. In its more aggressive setting the track-only model produces 30 percent more downforce than the base LaFerrari in the same configuration for a total of 540 kg (1,190.5 pounds) of downforce at 200 km/h (124 mph). That is sheer insanity.

Ferrari did a good bit of tinkering under the hood of the FXX K too, as it modified the 6.3-liter V-12 by replacing the hydraulic tappets with mechanical units, redesigned and polished the intake manifolds, modified the exhaust design, and removed the exhaust silencers. These mods push the 6.3-liter engine to 860 horsepower —  a 60-horsepower increase. The electric motor’s output also received a tweak, pushing it to 190 horsepower —  a 27-horsepower bump — for a total output of 1,050 horsepower and more than 900 Nm (663 pound-feet) of torque.

The FXX K will be available in 2015, but pricing and the details around purchasing one are still unknown. In the past, Ferrari has been rather persnickety about who buys an XX model and whether or not buyers can actually keep them at home, and I bet this will be the case with the FXX K.
