During the Ferrari Racing Days at Spa-Francorchamps tjey filmed the new Ferrari FXX K EVO on track. A 1,036bhp, harder version of the track-only FXX K that bullies the air around it into submission? Mama Mia.

The Evo is a development of the Ferrari FXX K, which is a weird sentence to say because not once in its lifetime have we ever thought, ‘yeah, that could do with a bit of tweaking’. But tweak it Ferrari has. The headline to zero in on is the increased downforce over the ‘regular’ FXX K, thanks to a raft of changes including a new fixed rear wing with many cool things.

Here, we want to take a moment to comprehend the Evo’s numbers. We suspect you might too. Three-point harnesses all bolted up? Good. Let’s begin… It produces 1,036bhp, and over 664lb ft of torque from a 6.3-litre V12 and electric motor.

The V12 alone pumps out just under 850bhp and 553lb ft of torque, while the motor adds a further 187bhp. Add that all together and you get a big number not afraid to keep you awake at night in a cold sweat. (And yes, it’s exactly the same as the regular FXX K.

Deal with it – you really don’t need any more power.) It’s channelled through a seven speed F1 dual-clutch gearbox to simply monster 20in, 345-section rear wheels. The fronts, incidentally, are 19s. Ah downforce, the Evo’s party piece. If bullying the surrounding air can be called a ‘party’.

It produces 640kg at 124mph, and over 830kg at the car’s top speed. Ferrari tells us the downforce available on the Evo is 23 per cent more than the FXX K, and a whopping 75 per cent more than LaFerrari is able to muster.

Breaking it down, the rear setup alone – wing, vanes and the like – adds ten per cent additional downforce. Then there are changes to the rear arches to better channel wake, adding a further boost of five per cent downforce.

The front redesign adds ten percent over the FXX K, using tricks Ferrari learned in its GT racing programme. Finally, vortex generators on the Evo’s underbody create an extra 30 per cent of downforce over the FXX K. We can’t say about how fast it is, because Ferrari hasn’t revealed any acceleration or lap time data. But we suspect the time starts with ‘VERY’ and ends in ‘FAST’.

The FXX K managed to scorch a time around Ferrari’s private Fiorano test track in just 1m 14s, which is five seconds faster than the road-going LaFerrari. So with the additional downforce and trick aero, we suspect the FXX K Evo might even dip into the 1m 13s… Mind you, it has plenty of electronic assistance, as one would expect of an XX car. There’s F1 traction control, Ferrari’s third-generation e-diff, high-po ABS and electronic brake distribution, and reconfigured dampers.

No specific data from Ferrari about the weight. It only notes that using experience from Formula 1, and adopting much carbon fibre, it managed to produce a car lighter than the FXX K, even with that new wing. Now consider that the FXX K itself shed around 90kg from LaFerrari to weigh in at around 1,255kg…

That lighter-than-1255kg figure is split via a 41 per cent front/59 per cent rear distribution. It measures in at 1.1m tall, with a wheelbase of 2.66m, if you’re really interested.
