Ferrari has had a string of track special cars since a while now and now they’ve unveiled their most extreme track only car yet, the FXX-K Evo. Over the already existing FXX-K, the Evo gets 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. 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. All this work means the Evo generates 640kg of downforce at 200 km/h, and more than 830kg at full speed.
Power comes from the same hybrid-boosted V12 as the standard FXX-K, with 1063bhp 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.
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 program in 2018/19, spanning nine racetracks between March and October.
