More downforce for track-only Prancing Horse
The Ferrari FXX-K has been treated to a comprehensive package of upgrades for more speed, more grip and even less weight. With an aerodynamics package inspired by the full spectrum of motorsport categories, and no road rules or FIA regulations to hold it back, the FXX-K Evo will be available only to the most valued of Ferrari customers.
Swapping from FXX-K to FXX-K Evo involves some serious aerodynamic changes. Ferrari says it spent 12 months honing the new aero package in computational fluid dynamics and wind tunnel testing, giving the car a downforce coefficient 23 per cent better than that of the regular FXX-K, and around 75 per cent better than that of the road-going LaFerrari.
Central to the improvements is a 'twin-profile' fixed rear wing, working in tandem with the existing active rear spoiler. The wing is backed by two side fins and a central fin, designed to support the trio of vortex generators in place to clean the air flowing from the rear of the bonnet radiators.
Tweaks to the bypass vent on the rear wheel arch have improved airflow to the diffuser, creating five per cent more downforce.
To balance the extra downforce on the rear end, Ferrari has modified the shape of the front bumper and added a set of small flicks. The company says these tweaks create 10 per cent more downforce than before, making use of lessons learned in GT racing.
Finally, ground effects have been added to the underbody, helping generate 30 per cent of the extra downforce the car creates.
All this work means the Evo generates 640kg of downforce at 200 km/h, and more than 830kg at full speed.
From behind the wheel, the biggest change to the FXX-K is the steering wheel with its integrated shift paddles, along with a bigger new rear-view camera display and telemetry system. Drivers can keep an eye on the car's vital signs, monitor their lap times or track their KERS levels through the new setup, which is said to be clearer and easier to understand.
Power comes from the same hybrid-boosted V12 as the 'regular' FXX-K, with 773kW of power and more than 900Nm of torque on call. It's put to the rear wheels through a seven-speed dual-clutch transmission. Ferrari has tweaked the double-wishbone front and multi-link rear suspension to handle the extra downforce.
Pirelli P Zero slick tyres – with sensors embedded, naturally – are standard, as are carbon-ceramic brakes. This is a serious car, designed for serious track work, and the hardware reflects that.
As with the rest of the FXX series, the FXX-K Evo isn't road legal. A 'limited number' will be produced, and existing FXX-K owners will be able to upgrade their cars to Evo specification. Owner cars will be rolled out as part of the XX Programme in 2018/19, spanning nine racetracks between March and October.
And if you need to ask how much the whole setup costs, you probably can't afford it.
