The basics, then. The entirely-not-road-legal FXXK employs the same basic V12-plus-electric drivetrain as the road-going LaFerrari, but making even more power. 101bhp more power, to be precise, boosting total output to 1036bhp: 848bhp coming from the 6.3-litre naturally aspirated V12 (at 9200rpm, no less) and 187bhp from the electric motor. Combined torque stands at ‘over 664lb ft'.

The internal combustion engine has been substantially overhauled for track duty, with new camshafts, redesigned intake manifolds and, most intriguingly, mechanical tappets replacing the traditional hydraulic efforts.

Ferrari also notes that the silencers on the exhaust system have been ‘eliminated', an appropriately sinister word for a noise likely to cause lasting, wonderful aural damage.

Though there's no word on a 0-62mph time, that extra power - along with some mighty trick-sounding Pirelli slicks, which feature embedded sensors feeding back information on longitudinal, lateral and radial acceleration - will mean a substantial decrease on the road-going LaFerrari's 2.9-second benchmark. Fast.

Aero? You can't handle the aero. The FXXK has sprouted a whole bunch of additional devices of downforce, innovations Ferrari says are derived from its expertise in endurance racing's GT category. At the front lurks a deep, double-deck spoiler, with vertical fins that channel air over the car's flanks, and boost the efficiency of the aerodynamic underbody.

There's yet more madness round the back, where a monster diffuser optimises air extraction from the underbody, and makes the FXXK a bugger to reverse-park.
