Concept or production: Production
What is it: The F1 of GTB Fioranos.
Highlights: Ferrari has X-rated another car, this time the lovely 599, with a track-only overhaul.
The purist Fezza cannot be driven on the road nor used in any current competition with its long list of outlandish mods. The powertrain has been fiddled from intake to exhaust, now producing 522kW and revving to 9000rpm.
A new traction management system called the 'High Performance Dynamic Concept' debuts on the car, seeking maximum grip under hard driving through engine management and suspension. This is linked to a 'virtual engineer', like an extreme chrono, which shows the effectiveness of the car's setup on an LCD screen and ultimately making it easier to tune.
The body gets bigger air ducts, winglets, splitter and spoiler, and it is fitted with 19-inch full slicks.
Like the previous FXX, Ferrari will be holding exclusive invite-only track days for owners and interested parties in 2010 and 2011.
According to Ferrari, it laps Fiorano in 1:17 secs. The Ferrari 430 Scuderia is timed at 1:23.9secs...
Also-shows: A Handling GT Evoluzione (HGTE) pack for the 599, with track-mod suspension, thinner rubber and a fatter look.
OFFICIAL PRESS RELEASE
Ferrari at Geneva with the HGTE package for the 599 GTB Fiorano and the world premiere of the 599XX
599 GTB Fiorano with the Handling GTE package
When it first debuted, the 599 GTB Fiorano set a new standard in terms of performance that remains a benchmark for new sports car development to this day. Now Ferrari is introducing the new Handling GTE (Handling Gran Turismo Evoluzione) package for the model to further underscore its sportiness and handling.
The package includes a modified set-up with stiffer springs and rear anti-roll bar as well as new calibration settings for the magnetorheological shock absorbers when the manettino is at its sportier settings. The ride height has also been lowered which in turn lowers the car's centre of gravity. This combined with the new set-up helps improve body control. The package also includes specifically optimised tyres featuring a compound that offers even better grip.
The car's electronics have also evolved to ensure even more prompt response to driver commands. The F1 gearbox's shifts are now even faster in high-performance settings, while a new engine software strategy has improved accelerator response.
The exhaust silencer has also been modified with the result producing an even more marked and thrilling sound under hard usage whilst still delivering just the right comfort levels at cruising speed.
From a styling point of view, the package also includes some distinctively sporty exterior and interior features with carbon-fibre widely used in the latter. The 20" split-rim wheels are new with a special diamond-cut and matte silver finish. The rear diffuser is finished in matte black to underscore the car's new set-up and highlight the chromed tail pipes. The cabin is sportier too thanks to a sophisticated mix of full-grain leather, black Alcantara® and carbon-fibre trim.
The new seats are trimmed in a new two-tone combination of leather with black Alcantara® inserts, and the seat backs are trimmed entirely in carbon-fibre. Embroidered in contrasting stitching on the headrest are a Prancing Horse and the words "Handling GTE".
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.
