They teased us first, but now they are showing it off: this is the Ferrari 599XX concept. The prototype is based on the 599 GTB Fiorano, and uses several new technologies to make it an ultimate performance-oriented track car.
One angle Ferrari engineers attacked was the weight of the engine unit and its components. Here, they made use of carbon-fiber intake plenums, and used new designs on parts like the crankshaft to reduce the amount of material needed. The combustion chambers and airflow systems have also been revampted to increase revs up to 9,000. All the improvements to the engine helped boost power up to 700 hp.
They also designed a new electronic system, called the "High Performance Dynamic Concept." This is meant to get the car's full potential by "managing the combination of the car's mechanical limits with the potential of its electronic controls." Essentially, this has the full mechanics working in tandem with the electrics to get the best possible lap times whenever the car is put to the track.
A new SCM suspension improves handling on the car, while custom slick tires increase stability in the corners. Meanwhile, a new video panel, called the "virtual car engineer," provides real-time information on the car's efficiency. F1-style "doughnuts" partially cover the brake discs and wheel rim, which keeps the brakes cool while improving aerodynamics.
Aerodynamics in general were improved. The 599XX generates 280 kg of downforce at 200 km/h, and 630 kg at 300 km/h. vents that move hot air out of the engine bay was moved to the front, as the underside of the front is entirely "faired-in." They have also created an "Actiflow" system to increase downforce, and cut drag. This is done through the use of "porous material" when building the fans in the boot and the diffuser.
We could go on about the carbon-fiber, aluminum, and composite body, or the new carbon-ceramic brakes. But in the end, the fact remains:
This is a beautiful car, and it has been made even better.
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 "ActiflowTM" 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 callipers 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.
