· 15 · · 14 ·The 911 GT2 |
The 911 GT2
Drive is transmitted through a pre-
cision six-speed manual gearbox.
Rear-wheel drive provides driving
dynamics that are similar to those
of a racing car. In the 911 GT2,
Porsche also uses a special system
for conventional manual transmis-
sion: the Launch Assistant (see
page 38) – for maximum accelera-
tion from a standing start.
For a sporty but still comfortable
drive, particularly for this type of
sportscar, the standard suspension
features variable damping providedby Porsche Active Suspension
Management (PASM, see page 48).
This active damping system offers
a wide range of benefits including
greater performance and comfort.
Also standard is Porsche Stability
Management (PSM, see page 50).
For the first time, the integrated
control systems for lateral and lon-
gitudinal dynamics, stability control
(SC) and traction control (TC) can
be fully disabled in two stages for a
more natural drive. This means thecar can also be enjoyed to maxi-
mum effect on the racetrack.
The one-piece 19-inch GT2 alloy
wheels of the 911 GT2 are fitted
with road-legal sports tyres as
standard. In size 325/30 ZR 19 on
the rear, these are 20 mm larger
than on the 911 Turbo. The special
tread and compound enable
tremendous lateral acceleration
and higher cornering speeds as
well as precision handling and
turn-in characteristics on either
road or racetrack. A range ofsetup options is available for
racing use, including ride height,
camber, toe angle and front/rear
anti-roll bars.
Developed in motorsport, and
standard on the 911 GT2 is the
Porsche Ceramic Composite
Brake (PCCB, see page 58).
The discs are made from specially
treated carbon fibre and are
approximately 50 % lighter than
comparable metal alternatives.
The results: better brake perfor-mance, greater agility and lower
fuel consumption.
Sports bucket seats (see page 72)
with folding backrest, integral
thorax airbag and manual fore/aft
adjustment, are fitted as standard.
A perfect driving position is essen-
tial in a car with the performance
potential of the 911 GT2. The latest
Porsche Communication Manage-
ment (PCM, see page 76) is also
fitted as standard. This features
a new 6.5-inch touchscreen for
intuitive control.We believe that you don’t have
to exploit the full potential of
the 911 GT2. But you may well
choose to.

The 911 GT2 |Chassis
The steering system is extremely
direct and provides detailed
feedback from the road. This
high level of precision is very
advantageous in both racing and
normal road use. Thanks to the
precise front-axle kinematics andthe variable steering ratio, the
car responds to every movement
of the wheel.
An important feature of the
steering system is the variable
ratio gearing. Around the straight-ahead position, the ratio
is less direct, enabling smoother
manoeuvres, such as during
motorway driving. There is less
risk of excessive steering inter-
vention destabilising the car at
high speed. Naturally, the systemprovides excellent feedback as
well as the usual agility. As the
wheel is turned harder, the ratio
becomes more
direct and the
steering more responsive. This
variability is
particularly beneficial
in low-speed hairpin bends. The
energy-absorbing steering column
is a key safety feature since, in
the event of a front-end impact, it
enables a deformation path of
100 mm.The intermediate steering shaft is
made from aluminium, while the
protective tube and steering lock
housing are die-cast magnesium.
The standard three-spoke GT2
steering wheel features manual
height and reach adjustment.
Used in conjunction with the seat
adjustment options, it enables
every driver to find the ideal seat-
ing position.
Maximum precision, however powerful the performance.

The 911 GT2 |Safety
Porsche Side Impact Protection
(POSIP).
The 911 GT2 is equipped as
standard with the latest generation
of Porsche Side Impact Protection
(POSIP). It features two additional
airbags for each front seat: a
head airbag located in each door
and a thorax airbag in the folding
Porsche Side Impact Protection (POSIP)
The airbag control unit is located
in the centre tunnel where it
receives additional information
from a pair of impact sensors
near the headlights. This arrange-
ment allows faster and more
accurate crash evaluation and
thus better airbag deployment.Airbags.
The 911 GT2 has a specially
developed airbag technology
with a total of six airbags. The
full-size front airbags have a two-
stage inflation function which
deploys each airbag separately in
accordance with the force and
nature of the impact (e.g., frontal
or diagonal) before inflating each
airbag accordingly. In a low-speed
crash, the airbag is only partially
inflated, thereby minimising
discomfort to the occupants.
backrest on each of the standard
sport bucket seats (see page 72).
As well as offering exceptional
support, the sport bucket seat
provides a much higher level of
safety than conventional bucket
seat designs.
The thorax and head airbags each
have a volume of approximatelyeight litres, providing high protec-
tion in the event of a side impact.
Another important element of
POSIP is the side impact protection
with door reinforcement.
Other safety features of the
911 GT2 are head restraints that
are an integral part of each seat,
an energy-absorbing steering column, three-point seat belts
with height adjustment, seat-belt
pre-tensioners and force limiters,
energy-absorbing elements in the
dashboard, and flame-retardant
materials throughout the interior.

Sport bucket seats.*
A car that is capable of such
extreme lateral loads requires a
seat with exceptional support. The
standard sport bucket seat has
manual fore/aft adjustment plus
two additional features rarely
encountered on comparable seat
designs: a folding backrest and
an integral thorax airbag in the
side support.The folding function enables easy
access to the rear luggage area.
The backrest pivots are positioned
high in the side bolsters, providing
optimum support for the torso,
pelvis and legs. This is the first
time ever that the lateral support
of a bucket seat has been com-
bined with a folding backrest.The backrest shell has a glass-fibre
reinforced plastic core and a
carbon-fibre surface with visible
weave pattern. This construction
provides excellent rigidity while
also reducing weight. The seat is
compatible with a six-point racing
harness.
The sport bucket seat features
black leather with Alcantara centre;
Dark Grey natural leather withAlcantara centre is also available
as an option. In conjunction with the
Clubsport package (see page 64),
it has a special flame-retardant
fabric finish for added safety.
Adaptive sports seats.
Adaptive sports seats in leather
with Alcantara centre are also
available as a no-cost option. This
alternative seat option combines
excellent comfort with first-rate
track performance. The compre-
hensive range of power adjustment
controls includes fore/aft position,
squab height, backrest angle and
lumbar support. The side bolsters
on the backrest and squab arepneumatically adjustable for the
perfect fit. This exceptional vari-
ability ensures generous comfort
on long-distance journeys or
precision support on the race-
track. A memory function includes
both exterior mirrors as well as all
seat settings on the driver’s side,
with the exception of the side bol-
sters. The adaptive sports seats
are also optionally available with
seat heating.
Storage compartments.
The everyday usability of the
911 GT2 is as important as its
performance, as evidenced by
the storage compartments in thecentre console and door panels.
Matching upholstered armrests
above the storage compart
ments
provide optimum driver comfort,
particularly on long-distance trips.
Twin cupholders for driver and
front passenger are neatly
concealed below the passenger
airbag. Underneath is a lockable
glove compartment with handy
CD storage.
Two 12-Volt sockets (including the
cigarette lighter) provide power
for all your accessories.
