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.
