The Ferrari FXX K will be unveiled next weekend at the Yas Marina Circuit in Abu Dhabi, and improves upon the company’s first hybrid supercar ‘LaFerrari‘. The K in its moniker is a reference to the “KERS” kinetic energy recovery system it adopts in maximising its track performance.
The car’s enormous potential is attested to by two significant figures: a total power output of 1050 HP (860 hp 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 engine 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.
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.
