Ferrari has released more detailed information on the Ferrari 599XX, the extreme track car that is helping the legendary supercar maker develop new technology for future road-going supercars. First seen at this year’s Geneva International Motor Show, a limited number of 599XXs will be available for sale to Ferrari’s most valued customers, but Ferrari will prepare and run the cars on behalf of their owners, enabling them to drive them at special events at Ferrari’s own Fiorano test track and at leading race tracks in Europe and the USA. Data gathered from these track days will be used to further enhance and develop technology for future frontline Ferrari models.
This includes reducing internal friction in the engine, faster gearbox operation, aerodynamics that automatically adjust depending on whether the car is cornering or going in a straight line, as well being speed dependent, and a new high speed adjustable chassis. New weight saving ideas are used throughout the car, including carbon fibre brake calipers.
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 friction has been reduced and the maximum revs have been boosted to 9000rpm, helped achieve the target power output of 515kW at 9000rpm.
Particular attention was also paid to cutting the weight of the engine unit components. This was achieved both by optimizing 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 gear change times to 60 milliseconds. The chassis of the 599XX uses an innovative electronic model 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 aggressive 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 track performance. The 599XX’s aerodynamics were honed in numerous wind tunnel test sessions with the result that the car now boasts 280kg of downforce at 200km/h and 630kg at 300km/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 599XX comes with slick tyres (29/67 R19 Front and 31/71 R19 Rear) specifically developed to maximize 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.
