World premiere of the FXX K at the Ferrari Finali Mondiali
Ferrari’s new FXX K research and development programme will receive 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 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 demonstrated 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 6262cc 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.
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.
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.
