Ferrari
FXX K track car based on the LaFerrari
It was anticipated from moment the covers were first pulled back
on the Ferrari LaFerrari, speculatively
rendered at least once, but here it is for real. The Ferrari FXX
K race car, the super-exclusive, track-only version of the LaFerrari.
The Ferrari FXX K takes the LaFerrari's styling to the extreme. From
some angles it looks more like a fictional whacky racers machine,
or something a Hot Wheels designer might come up with. The front of
the FXX K gets a larger twin-level front spoiler and a massive air
splitter which sits 30 mm lower than on the road car. The front end
design was influenced by aerodynamic lessons learnt from Ferrari's
race cars in the GT category. End plates on either side of the splitter
channel air down the car's sides, creating a low pressure vortex which
sucks turbulent air away from the wheels to reduce drag.
At the rear of the Ferrari FXX K, Ferrari's aerodynamic engineers
have created a taller tail section, and also fitted a vertical fin
and small spoiler to the end of each rear 1/4 panel. These small spoilers
are designed to work with the main rear wing - which can be extended
for more downforce, or retracted for a higher top speed. When the
spoiler is retracted the small fins act as guide vanes for the air
flowing around the car, and when the spoiler is extended they increase
its efficiency by channeling air over it.
The underside of the car has its own airflow management system
which has helped drastically improved downforce by up to 50 percent
- depending on the car's aero setup.
Just like in the LaFerrari road car, powering the Ferrari FXX K is
a hybrid setup - in fact the K stands for KERS (Kinetic Energy Recovery
System). The 6.3 litre V12 provides most of the power, 846
horsepower @ 9,200 rpm, and 538 ft-lbs of torque @ 6,500 rpm. While
a 187 horsepower electric motor provides the rest. The total power
output of the system is 1,035 horsepower and 663 ft lbs of
torque.
Internal modifications to the FXX K's engine over the standard road
going unit include new camshafts and mechanical rather than hydraulic
tappets. The intake manifolds have also been redesigned as well as
polished for smoother air flow. The car also gets new exhausts and
as it doesn't need to comply with street car regulations, the silencers
have been removed.
The interior of the car is filled with racing-specific modifications
and a number of advanced driver aid systems. One of the more prominent
is the 4-setting Manettino switch which adjusts the car for different
requirements. Qualify, for maximum performance within a limited number
of laps; Long Run to optimise performance consistency; Manual Boost
for instant maximum torque delivery; and Fast Charge, for a fast recharge
of the car's battery.
The intervention level of the E-Diff electronic differential,
F1-Trac traction control, Racing SSC (Side Slip Angle Control) - now
specially calibrated to suit the car's slick tires - and the high-performance
ABS can be controlled using a switch on the steering wheel.
The price of the Ferrari FXX K? Roughly $3 Million USD - for
that you get 2 years of Ferrari Racing support, after the two years
are up you can buy in again for an undisclosed amount.
Ferrari currently plan on building just 40 cars.
