Ferrari FXX K

Ferrari FXX K research and development programme receives its world premiere 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 its track performance.
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 coming two years.
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.

FXX-K is Ferrari’s research and development programme centring around a laboratory car based on Maranello’s first hybrid. The K in the new car’s moniker is a reference to the KERS kinetic energy recovery system used to maximise performance on the track.  Unfettered by homologation requirements and regulations, the FXX-K will never be used in competition and was developed to be completely uncompromising. It incorporates an array of technological innovations that will guarantee an unprecedented driving experience to the exclusive group of Client-Test-drivers with which the Prancing Horse will roll out a special test programme over the next two years.

Ferrari brought a bunch of its XX models out to play at Yas Marina, but the reason to watch this clip is to see the new FXX K in motion. It makes the noises we all wish current F1 cars made.
And it hustles, too. After all, there's 1035 combined horsepower on tap—in addition to187 hp of electric motivation there's the slightly-tweaked 6262cc V12 from the standard LaFerrari, massaged to pump out an extra 89 horsepower.
10 years ago, Ferrari launched the FXX, an Enzo-based, track-only monstrosity that you couldn’t bring home to mother. No, literally, you couldn’t. Maranello retained custody of the unholy beasts, hauling them to events for owners to race against each other. Hailed as a pinnacle of Ferrari tech, of sorts—a crowdfunded R&D program, one might say—the XX program continued with a 599 variant. Ferrari has now unveiled the third car in the program’s history, the LaFerrari-based FXX K. €2.5 million (roughly $3 million) buys you the car and two years of Ferrari’s stewardship. It’s also perhaps the most mind-bending thing to roll out of Maranello since the F40 set us on our ears more than a quarter-century ago. We went to Abu Dhabi to see the latest, craziest horse prance around the Yas Marina Circuit. Here’s what we learned.
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 to boost its efficiency.
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 car by a by-pass duct.
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, F-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.
