Few cars on the planet can match the 1036bhp power output of the Ferrari FXX K.

From inside the cabin there's a rugged simplicity to it, stripped down to the bare essentials to squeeze out the extra 101bhp over the LaFerrari it’s based on.

I’m examining the car from the passenger seat at the start line of the hillclimb at Goodwood. My driver is Pat Blakeney, the operations manager for Thruxton circuit, and he’s a man under pressure.

Pat has driven for Ferrari at events for the past 15 years and now he’s behind the steering wheel of the FXX K, leading the lineup on the final run of the opening day of the Festival of Speed.

The morning run ended in disappointment. The FXX K’s battery and KERS system didn’t agree with the stop start nature of the procession towards the hillclimb, so the car could only limp up the hill and its weekend participation was put into doubt.
