Man kunde väl kanske inte vänta sig något annat än att banversionen av Ferrari LaFerrari skulle bli galen. Och nu är den här, och den kallas för FXX K. Superbilen har blivit ännu mera super och bjuder nu på hela 1 036 hästar. Men både hästarna och bilen får som sagt endast tyglas på bana.
Grunden är samma som hos vanliga LaFerrari vilket innebär en V12:a på 6.3 liter kopplad till en elmotor. Men här har alltså effekten skruvats upp med 101 hästar, och ligger nu på 1 036. Det totala vridet ska ligga på över 900 Nm.
Förbränningsmotorn har givetvis setts över och preppats så mycket det bara går för att palla med tung och påfrestande bankörning. Ljuddämparna har man valt att strunta i helt, så det här lär bli en helt sjuk upplevelse även när det kommer till ljudet. Elmotorn har också modifierats en aning och det ska finnas fyra olika inställningsmöjligheter att välja mellan - Qualify (maxeffekt), Long Run, Manual Boost och Fast Charge. Några siffror kring bilens prestanda får vi inte för tillfället, men dessa lär också vara galna.
I övrigt förses bilen med en del extra prylar för att säkra optimal downforce i alla lägen. Något som får den att se ut som Batmans senaste åk. Totalt har ingenjörerna lyckats ge FXXK hela 50 procent mer downforce jämfört med vanliga LaFerrari - och då skäms knappast den bilen för sig.
Namnet då? FXX har vi hört sedan tidigare men k:et är nytt. Det symboliserar helt enkelt att det finns ett kinetic energy recovery system ombord, och är alltså inte en rolig skrivning av det där engelska ordet som vissa ibland använder sig av när de vill uttrycka ilska.
Det ryktas om att prislappen kommer att ligga på tre miljoner dollar och att det endast kommer att byggas 30 stycken exemplar. Bilens tekniska specifikation hittas under "Läs mer".

Maranello, 03 December 2014 – Ferrari’s new FXX K research and development
programme receives its world premiere next weekend at the Yas Marina Circuit
in Abu Dhabi. The laboratory-car is based on Maranello’s first hybrid model
and will grace the world’s tracks from next year onwards. The K in its moniker is
a reference to the “KERS” kinetic energy recovery system it adopts in maximising
Unfettered by homologation and racing regulations, the FXX K will never be
used in competition. It was, in fact, developed to be completely
uncompromising, incorporating technological innovations that will guarantee
an unprecedented driving experience to the exclusive group of Client-Test
Drivers with whom the Prancing Horse will roll out a test programme over the
The car’s enormous potential is attested to by two significant figures: a total
power output of 1050 cv (860 cv delivered by its conventional V12 engine and
190 by its electric motor) and maximum torque in excess of 900 Nm.
The FXX K’s 6262 cc V12 features new camshafts and a modified valve train
with mechanical rather than hydraulic tappets. The intake manifolds have been
redesigned and given a special type of polishing treatment. The exhaust system
has been modified as its silencers have been eliminated.
The HY-KERS system has been evolved specifically for pure performance with
the result that the driver can control the function logics from the specific 4-
setting Manettino on the centre console: 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.
A focus on delivering maximum efficiency at every stage of every track lap has
resulted in extensive but integrated work on the entire car body in terms of both
active and passive aerodynamics.

The front of the car is dominated by a twin-profile spoiler and a larger splitter,
which is 30 mm lower, with a gap in its centre. This design is an application of
the concepts developed to improve aero balance in the GT category of the
WEC, which Ferrari has won for three consecutive years. Two pairs of vertical
elements, an endplate and, externally, a dive plane, together with vertical fins
channel the air towards the car’s flanks, generating a longitudinal vortex that
creates a localised depression. This in turn sucks the wake from the wheels to
the outside of the aerodynamic underbody. Along with the side skirts that
extend out from the sills, the vortex helps isolate the airflow from the underbody
The solutions on the rear of the car are highly sophisticated, too. The tail
section is now higher and the mobile spoiler extends further for a total increase
in extension of 60mm when fully deployed. A vertical fin and a small wing each
side of the tail act as guide vanes in the low drag configuration and boost the
spoiler’s efficiency in the high downforce one. This system also
creates considerable downforce at the rear of the car, allowing the use of an
extreme diffusion volume for the rear diffuser which optimises air extraction
from the underbody. The section of the flat underbody just ahead of the rear
wheels is also exploited to the full to generate downforce thanks to the reduced
pressure in the wheel arch guaranteed by the direct connection to the rear of the
The result is a 50% improvement in downforce in the low drag configuration
and a 30% improvement in the more aggressive downforce configuration,
resulting in a figure of 540 kg at 200 km/h.
Vehicle dynamics are further improved by the adoption of Pirelli slicks complete
with sensors that monitor longitudinal, lateral and radial acceleration, as well
as temperature and pressure. This ensures an accurate analysis of the
interaction between the tyre and track surface, providing even more vital data to
enable the traction control system to guarantee maximum performance.
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 tyres - and the high-performance ABS can be controlled using the
five-position Manettino on the steering wheel.
