Ferrari FXX K unveiled: 1035-hp dream machine
Making its first public appearance at the Yas Marina F1 circuit in Abu Dhabi, the new Ferrari FXX K is a high-velocity test bed of hybrid technology. Based on the already incredible Ferrari LaFerrari street car, this even-more-potent limited-production, track-only derivative was developed for an exclusive group of Client-Test Drivers the chance to participate in an evaluation program at various racing venues over the next two years. While reprising the FXX nomenclature Ferrari used on the Enzo-based hypercar it produced from 2005-2007, this latest iteration adds a "K" to indicate the presence of an F1-style KERS (kinetic energy recovery system) that augments its 6.3-liter naturally aspirated V12 to crank out 1035 total horsepower.
To gain those extra 85 horses, Ferrari engineers tweaked both the engine and the electric motor. The V12 upgrade includes a revised intake manifold, new cylinder heads, a modified valvetrain with redesigned camshafts and a freer-flowing exhaust system with no mufflers. No word on what was done to up output of the electric motor by roughly 13 percent, but the HY-KERS system has been evolved to bias it even more toward pure performance. The system, controlled by the Manettino selector on the center console offers four choices. "Qualify" gives maximum performance for short periods, "Long Run" optimizes performance consistency, "Manual Boost" gives instant delivery of the car's 664 lb-ft of peak torque and "Fast Charge" dials up the quickest on-the-fly replenishment of the floor-mounted lithium-ion battery pack. Motive force gets sent to the rear wheels via a 7-speed dual-clutch transmission and while Ferrari offered no acceleration info, the FXX K should deliver significantly better stats than the LaFerrari which sprints to 60 mph in less than 3.0 seconds and tops out at 217 mph.
Making sure the Ferrari FXX K can fully exploit that potential, the development team made sweeping changes to the aerodynamics and the chassis using tricks learned from its successful World Endurance Championship GT racers. The dramatically recast front clip works with skirt elements on the side sills to channel air around the car while the elevated tail features an active center spoiler, huge lower diffuser and a pair of high-mount mini winglets that provide the proper balance. Collectively, Ferrari says the exterior remake yields 50 percent more low-speed downforce and bumps high-speed stick by 30 percent. The LaFerrari's trick magneto-rheological damping system and Brembo carbon-ceramic brakes carry over, as does its E-Diff electronic differential and F1-Trac traction control. But the Racing Side Slip Angle Control has been recalibrated to accommodate the fitment of Pirelli competition slicks. Here, too, everything can be adjusted via a second 5-position Manettino on the steering wheel.
No word yet on how many FXX K models Ferrari plans to build, but it produced only 30 original FXXs. Pricing for this de facto rival to the McLaren GTR also has not been released, but plan on it starting substantially north of the $1.35+ million a base LaFerrari commands. And like the FXX, access to this even more stunning Ferrari will be by invitation only.
