Ferrari
announce the 599 GTO, an extreme V12 berlinetta
developed to a specific performance-oriented brief which
will made its world debut at the Beijing Motor Show
later this month. The 599 GTO is, in fact, the company’s
fastest ever road car. It is an exclusive limited
edition special which, in true Ferrari tradition, is a
completely new concept, albeit inspired by a production
car. In fact the 599 GTO is based on the 599XX, the
advanced experimental track car, and can be considered
almost a road-going version.
The 599 GTO will be
reserved for just 599 clients who seek the maximum
expression of high-performance driving. The 599 GTO
benefits directly from the technological transfer from
racing and set a record lap time at Fiorano in 1’24”.
The Fiorano lap time
provides just one indication of the potential of this
car. Just as significant are the technical
specifications – 670 hp in a 1495kg car represents a
weight-to-power ratio of just 2.23 kg/hp, and ensures a
0-100 km/h acceleration time of just 3.35” as well as a
top speed of over 335 km/h.
Fundamental to the
GTO’s performance is the innovative approach to chassis
development which, for the first time on a production
car, saw the integration between a handling set-up tuned
for a level of responsiveness that is close to the limit
and highly sophisticated electronic controls. The result
is the almost complete absence of understeer and a truly
communicative chassis.
As is Ferrari’s
policy, every new Ferrari features new solutions for a
road car. Thus the 599 GTO is equipped with the latest,
second-generation carbon-ceramic brakes which are
lighter and offer better performance, new aerodynamic
innovations, such as the wheel doughnuts which increase
aerodynamic efficiency as well as improve brake cooling,
and the Supersport tyres developed by Michelin include a
wider front tyre for greater roadholding. The driver-car
interface is also new with the adoption of the Virtual
Race Engineer (VRE) which provides the driver with
instantaneous information on performance. The 599 GTO’s
more aggressive character is also apparent in a number
of styling elements that recall the 599XX and from the
powerful sound of the V12.
The GTO (Gran Turismo
Omologata) moniker instantly calls to mind two Ferraris
that have entered the collective imagination as symbols
of performance. After the 1962 250 GTO, which swept the
boards in GT racing categories in the 1960s and is now a
highly prized collector’s car, came the iconic 1984 GTO,
which basically invented the entire modern supercar
genre.
ENGINE AND GEARBOX
The 599 GTO’s engine
is directly derived from the 599XX unit implementing,
however, the necessary modifications for road-going
homologation. It thus complies with Euro 5 and LEV 2
standards. The 5999 cc 65-degree V12 engine punches out
670 CV at 8250 rpm with maximum torque of 620 Nm at 6500
rpm and there is a smooth, constant rush of power all
the way to the redline with no loss of flexibility even
at medium and low revs. This result was obtained by
working on the fluid-dynamics and components to reduce
internal friction and by adopting, amongst other things,
the 599XX’s redesigned crankshaft. The car also has a
racing-type intake system with a new manifold with
diffuser-type intake geometry and short inlet tracts
designed to improve power delivery at high revs and
reduce losses. To maximise volumetric efficiency per
cylinder, a connection between the two plenums at the
front compensates for variations in the volume. This is
how the engineers managed to achieve maximum performance
at high engine speeds. The engine sound inside the car
is carefully controlled to balance the intake sound with
the exhaust, which features a 599XX-derived 6-into-1
manifold. The 599 GTO features the same, lower 60 ms
shift times and the possibility to make multiple
downshifts as on the 599XX.
VEHICLE DYNAMICS
One of the most
significant innovations on the 599 GTO is the close
correlation between the chassis set-up, which is close
to the handling limit, and the input from the electronic
controls which are developed to increase overall levels
of performance. Since the very earliest states of the
two cars’ development, Maranello’s engineers worked to
ensure that these two areas of the car would be
seamlessly integrated thus pushing responsiveness to the
limit. The result is, of course, superlative driving
involvement as well as faster lap times. Apart from new
springs and a stiffer rear anti-roll bar, the car also
features a second generation magnetorheological
suspension control system (SCM2). The suspension works
in tandem with the VDC (Vehicle Dynamic Control) and
latest-generation F1-Trac traction control. This makes
the car extremely responsive to driver inputs - thanks
in part to the adoption of a very direct steering ratio
– but also very stable under braking, sharper on
turn-in, more precise in cornering and quicker out of
corners.
WEIGHT REDUCTION
The 599 GTO inherits
much of the development work - using the same principles
as employed in F1 - that went into making the 599XX such
an extreme performance car. Reducing weight was a vital
objective and the result was the widespread use of
composites and components manufactured with technologies
more akin to racing specifications. The areas involved
include the bodywork and greenhouse (with thinner gauge
aluminium and thinner glass), the brakes, transmission
and exhaust system. The result is a dry weight of 1495
kg and a weight-to-power ratio of just 2.23 kg/hp, a
very significant figure that underlines the GTO’s
performance potential.
AERODYNAMICS
The 599 GTO’s
aerodynamics have benefited significantly from Ferrari
engineers’ experience in F1 and with the 599XX which
allowed downforce to be greatly increased without
impacting on drag. Thanks to solutions transferred from
the track car to the road-going version, the GTO
generates downforce of 144 kg at 200 km/h. The entire
car was honed, including the front, the sides, the flat
underbody and cooling flows. In the latter instance, the
GTO can count on improved ducting to the brake discs and
pads, and the adoption of wheel doughnuts – a disc
positioned outside the brake disc that ensure that hot
air exiting the wheelarch stays as close to the body of
the car as possible to reduce drag. Work on the nose of
the car was aimed at reducing the width of the wake
generated by the front and thus reduce drag. The front
spoiler incorporates a separate lower wing that
increases downforce at the front of the car and
increases the flow of cooling air to the oil radiator.
On the flanks there’s a new sill design with a more
pronounced leading edge that improves the efficiency of
the central section of the underbody. The underbody
itself incorporates a new, lower front section with
diffusers ahead of the front wheels to optimise
downforce, and a new double-curve rear diffuser.
WHEEL RIMS AND
TYRES
Here the difference in
size between the front and rear tyres has been changed.
The GTO’s front tyres are now 285/30 on a 9.5’’ channel
with 315/35 on an 11.5’’ channel at the rear. The 599
GTO has 20’’ rims. Roll rigidity is greater at the rear
to minimise understeer. These solutions guarantee
improved lateral grip and quicker turn in.
BRAKES
The new CCM2 braking
system is lighter and even more consistent in high
performance situations. Its consistent coefficient of
attrition meant that the ABS could be calibrated to a
particularly high performance level, further reducing
lap times, thanks to improved deceleration and shorter
stopping distances. In fact, the 599 GTO boasts an
excellent 100 to 0 km/h braking distance of just 32.5
metres. As well as their role in improving aerodynamics,
the Formula 1-derived wheel doughnuts also improve
braking efficiency by optimising brake cooling.
CAR-DRIVER
INTERFACE
The car-driver
interface was designed to maximise car and driver
performance with a layout of the main commands that
ensures absolute efficiency and minimum distraction. The
Racing manettino also puts the emphasis firmly on
sporty, track-specific driving settings by offering the
driver full choice with regard to the electronic control
parameters. The ICE position on the 599 GTB Fiorano has
been replaced by CT-Off (traction control off). The GTO
is also fitted with bespoke, longer carbon-fibre F1
paddles for easier use in high-speed driving. In
addition the GTO also features the Virtual Race
Engineer, a system that monitors the status of the car
and gives the driver immediate visibility of vehicle
performance.
