Ferrari chose this busy automotive news day to release more info on the track-only 599xx. At least it would be new info if you missed our coverage of the U.S. debut of the supercar at the New York Auto Show.
We don’t mind giving you a quick run-through of the details. Besides, it’s a great excuse to look at all the new photos Ferrari released.
The most important bit of new(ish) info is that the 599xx has what Ferrari engineers have termed a “Virtual Race Engineer.” This system essentially uses all the onboard computers to calculate what the maximum level of performance the car can achieve on a race track. To do this it takes every bit of data available, including tire temperature, tire pressure, engine and coolant temperature (as well as many other variables) and determines what the maximum level of performance capable by the car under those conditions is.
Unfortunately, if you’re not Michael Schumacher, getting the car to go that fast is impossible… but here’s where the fun part comes in. The 599XX’s computer can then rate you (the driver) on your performance and tell you how close you are coming to the car’s maximum potential – a humbling experience no doubt.
One way that the 599xx’s computer helps a driver get the maximum performance out of the car is through the Actiflow system, which takes in air from under the car and uses two jets to shoot out air through outlets next to the taillights. This way the computer can control the level of lift/downforce on the rear of the car in accordance with the driving conditions.
In total, the 599xx can create 612 lbs of downforce at 124mph and almost 1,400 lbs of downforce at 186 mph.
As for the rest of the info, well, you probably already know by now that the V12 engine has been modified significantly to produce 700hp at 9000 rpm and that the new transmission control unit can now shift gears in as little as 60 milliseconds.
So what are you waiting for… just check out the gallery.

More on the 599xx after the jump:
While based on the 599 GTB Fiorano with the same transaxle layout and engine type, this prototype is an extreme track car. Ferrari’s engineers have carried out extensive work on the engine’s combustion chambers and inlet and exhaust tracts. These modifications, combined with the fact that internal attrition has been reduced and the maximum revs have been boosted to 9,000 rpm, helped achieve the target power output of 700 hp at 9,000 rpm. Particular attention was also paid to cutting the weight of the engine unit components. This was achieved both by optimising forms – as in the new crankshaft – and adopting exclusive materials, as in the carbon-fibre used for the intake plenums. A new gearbox shift strategy cuts overall gearchange times to 60 ms.
The 599XX is characterised by an innovative electronic concept called the “High Performance Dynamic Concept” which has been designed to get the maximum performance from the car by managing the combination of the car’s mechanical limits with the potential of its electronic controls. The mechanical and electronic systems work together to get the maximum performance from the car under extreme high performance driving, for consistent lap times. The sporty handling has been improved thanks to the adoption of second generation SCM suspension system. Track usage is also made easier thanks to the new “virtual car engineer”, a screen in the car that provides a real-time indication of the vehicle’s efficiency.
The 599XX’s aerodynamics were honed in numerous wind tunnel test sessions with the result that the car now boasts 280 kg of downforce at 200 km/h (630 kg at 300 km/h). The front underside of the body is completely faired-in and the vents that channel hot air from the engine bay have been moved to the bonnet.
The “Actiflow” system increases downforce and/or cuts drag depending on the car’s trim cornering conditions, courtesy of the use of a porous material in the diffuser and two fans in the boot which channel the air flow from under the car out through two grilles next to the tail-lights. Winglets have been added to the rear buttresses to increase downforce. while synthetic jets have also been incorporated into the rear of the car to control and smooth the air flow and to reduce drag.
Ferrari’s engineers have also used F1-derived “doughnuts” which partly cover the brake discs and wheel rim. These have the dual function of improving both aerodynamics and brake cooling.
In terms of the bodywork, composites and carbon-fibre have been widely used and the engineers drew on their experience in working with aluminium to reach the weight target. The development of increasingly high-performance materials has also benefited the carbon-ceramic material braking system. The brake pads are now made from carbon-fibre which means that the calipers are smaller whilst guaranteeing the same efficiency. The new racing carbon ceramic braking system also delivers shorter braking distances and is generally more efficient due to the weight saving.
The 599XX comes with slick tyres (29/67 R19 Front and 31/71 R19 Rear) specifically developed to maximise stability in cornering and increase lateral acceleration. They are fitted to 19 x 11J wheel rims at the front and 19 x 12J at the rear.
