First, there was LaFerrari, and it was good. Then came the LaFerrari-based FXX K, and it was wild. Now, just when you thought it was safe to go back into the water comes the deranged LaFerrari-based FXX K Evo.Time perhaps, to ponder in a haunted malaise whatever life choices have led you to the point where you can"t drive one of these things, because Ferrari is promising significant advantages over the already bombastic FXX K. Chief among which stands the car"s improved downforce.The FXX K Evo boasts 23 per cent more downforce over the FXX K, and an even more astonishing 75 per cent more downforce than LaFerrari. Is your brain even able to process that much additional downforce? We"re talking 640kg at 124mph, and 830kg at the "car"s red-line speed". Maybe just imagine the noise of an FXX K Evo attempting to produce max downforceAs with any self-respecting Evo, it"s all in the detail. And, if you"re not up to speed on wake and hot air flow, then apologies it gets a bit technical from here on in. The FXX K Evo gets a twin-profile fixed wing, designed to work in tandem with the active rear spoiler; indeed, the active spoiler"s control "logics" were reprofiled, too.That fixed rear wing also gets a pair of side fins and one central fin, the latter able to create more stability at "low yaw angles", and support the vortex generators (fins, to you and I). These little vanes help clean the air hitting the wing; specifically, the hot air flow created by those radiator bonnet vents. They also create downwash", which isn"t what you originally think it means it boosts the rear wing"s downforce capacity.The rear wheel arch vents have been enlarged, too, in line with the reprofiled rear wing, to more effectively channel the wake from the rear wheels. Considering the FXX K"s V12 boasts 1,036bhp sent to these wheels, there is much wake.
