Ferrari FXX K is the next wave of Super Sports from Maranello

    Ferrari FXX K_5 Ferrari last week premiered the FXX K (KERS) at the Yas Marina Circuit in Abu Dhabi. The R&D Super Sports, based on Maranello’s first hybrid variant, is stipulated to go into action at racetracks around the world, from next year onwards. A 2-year full-on test program is on the cards for the FXX K as well.

Here’s Ferrari’s description of the FXX K: The front of the FXX K is dominated by a twin-profile spoiler and a larger splitter, which is 30 mm lower, with a gap in its center. This design is an application of the concepts developed to improve aero balance in the GT category of the WEC (World Endurance Championship), 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 and generate longitudinal vortex. Along with the side skirts that extend out from the sills, the vortex helps isolate the airflow from the underbody to boost efficiency.

The solutions on the rear of the car are highly sophisticated, as well. The rear section is now higher and the mobile spoiler extends further for a total increase in extension of 60 mm 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. 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.

All said and done, there’s 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.

The FXX K boasts 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, thanks to a 6262 cc V12 powerplant with new camshafts and a modified mechanical valve train. Additionally, the intake manifolds have been redesigned and given a special type of polishing treatment, while the modified exhaust system has the silencers stripped off. With HY-KERS system, the driver is able to control the function logics from the specific 4-setting Manettino (Qualify, Long Run, Manual Boost and Fast Charge) on the center console.

In addition, the intervention level of the E-Diff electronic differential, F-Trac traction control and Racing SSC (Side Slip Angle Control) are now specially calibrated to suit the FXX K’s slick tyres, while high-performance ABS is operable via the five-position Manettino on the steering.
