						Ferrari has 
						released more detailed information on the Ferrari 599XX 
						project, the extreme track car that is helping it 
						develop new technology for future roadgoing 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 9,000 rpm, helped achieve the target power output 
					of 700 bhp/515 kW at 9,000 rpm. 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 gearchange times to 60 
					ms. 
					
					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 280 kg of 
					downforce at 200 kmh and 630 kg at 300 kmh. 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 "ActiflowT" 
					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. 
					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 metal 
					"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 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.
