When Ferrari lifted the lid on its ‘productionised test mule’, the 599XX, at the recent Geneva Auto Show, we were offered but a glimpse of the 599-based race-ready technological laboratory.

Not any more. Ferrari has released a slew of images depicting its latest experiment, which will only be on offer to privileged Ferrari customers and can only be driven at Ferrari-sanctioned track testing sessions.

A ‘regular’ 599 already looks pretty fine, but throw on a set of lightweight racing wheels, a couple of unorthodox C-pillar mounted wings and an active rear diffuser and you have one tough-lookin’ automobile. More pics after the jump.

The 599XX is designed to be a rolling testbed for Ferrari’s next generation supercar tech and although it’s a track-only proposition, much of the 599XX’s high-tech componentry may eventually trickle down to Ferrari’s future road-going offerings.

The 599XX’s V12 mill is based upon the standard car’s donk, reworked heads with low-restriction inlet and exhaust ports bump power up to a heady 522kW (700hp) at 9000rpm. Shift programming on the F1 derived semi-auto transaxle knocks shift times down to just 60 milliseconds, which is pretty darn quick for a non-twin-clutch gearbox.

Aerodynamics is a key focus of the 599XX, and it shows. A sizable front splitter sits under the 599XX’s chin, the entire underside of the car is flat, a louvered bonnet extracts heat from the engine bay, winglets at the rear of the cabin promote downforce and a fan-assisted rear diffuser sucks the car to the ground while simultaneously minimising drag.

The end result? 280kg of downforce at 200km/h, and 630kg at 300km/h.

Form AND Function? The 599XX has got both in spades.
