The 911 GT2 |Safety
Bodyshell structure.
The 911 GT2 complies with all
statutory requirements worldwide
in respect of frontal, side,
diagonal and rear impact
protection.
The reinforced bodyshell contains
a highly resilient passenger
cell offering exceptional crash
protection. At the front of the
car, the cell is protected by a
patented system of longitudinal
and transverse members (1). In
the event of an accident, energy
is absorbed by three separate
load paths, one above the other,
which disperse the force of
impact and minimise deformation
of the passenger cell.
Additional features include an
extremely rigid bulkhead cross-
member (2) made from super
high-strength steel. This element is
designed to absorb impact forces
from the longitudinal members and
thus protect both front footwells. In
a minor collision, a system of easily
replaceable impact absorbers
(3) prevents costly damage to the
underlying bodyshell structure.
The reinforced doors (4) make
an increased contribution to
the overall rigidity of the car. An
additional load path (5) is used tochannel energy through the upper
part of the shell and thus further
protect the passenger cell.
In 1985, we began using super
high-strength steel elements
inside each door to increase side
impact protection. On the 911 GT2,
this integral reinforcement
is made
from tough yet lightweight
aluminium. By increasing the
proportion of aluminium alloys
and high-strength steel, we’ve
also improved the power-to-weight
ratio. In all, approximately 20 %
of the 911 GT2 is made from
aluminium.Another important but perhaps
less obvious safety feature is the
high-quality surface protection.
More than 30 years ago, we
became the first manufacturer in
the world to use a hot-dip gal-
vanised steel shell. This exacting
process is fundamental to thelegendary durability of our cars. It
also ensures a consistently high
standard of crash protection, even
after many years on the road.

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.

ParkAssist.
This optional parking aid is auto-
matically enabled whenever you
select reverse gear. Move too
close to a stationary object and a
warning signal is emitted. Continue
to reverse and the tone increases
in frequency. The distance is
measured by ultrasonic sensors
which are neatly concealed in the
rear bumper.

An auto-dimming function is
available as an option for the
911 GT2 for interior and exterior
mirrors. The package also includes
an integrated rain sensor for the
front wiper system.
Luggage compartment.
The volume of the luggage
compartment in the 911 GT2 is
105 litres. The entire compartment
is lined with high-quality, scratch-
resistant materials. The bulkhead
panelling conceals the amplifier
of the optional BOSE
®Surround
Sound System and the DVD drive
for the optional navigation module.
The additional 205-litre rear load-
space inside the car is easily
accessible thanks to the folding
sport bucket seats.
Anti-theft protection.
The 911 GT2 has an engine
immobiliser with in-key transpon-
der as well as a powerful alarm
system featuring contact-sensitive
exterior protection and radar-
based interior surveillance as stan-
dard. The alarm system is
activated and deactivated by a
remote control function in the
ignition key.
Vehicle tracking system.
The 911 GT2 can also be equipped
with an optional factory-fitted
preparation enabling future
installation of a vehicle trackingsystem obtainable from Porsche
Tequipment. This system allows
a stolen vehicle to be traced
throughout most of Europe, and
requires the installation of a
special wiring loom and a high-
capacity battery.
Chrono Package Plus.
The optional Chrono Package Plus
combines a dash-mounted
analogue/digital timer with a range
of useful functions. Lap or journey
times can be viewed, stored and
analysed using the performance
display in PCM. The information
available includes time elapsed
and distance travelled on the cur-
rent lap, as well as the number
oflaps completed and their
respec-
tive times. You can also view the
current fastest lap and remaining
range till empty. Driving times can
be recorded for any stretch of
road, and benchmark times can be
defined. Other useful
features
include a personal

The 911 GT2 |Environment
Here, all technological developments
are carried out with environmental
protection in mind. The aim: pure
performance – but not at the
expense of the environment.
You can find more information
about environmental matters in the
separate brochure ‘Porsche and
the Environment’, or on our website
www.porsche.com.
Exhaust emission control.
The 911 GT2 easily meets the strin-
gent emissions standards for the
EU4 regulations in Europe and
LEV II regulations in the USA. This
demonstrates that even high per-
formance sports cars can achieve
moderate emissions values in their
respective categories. The 911 GT2
is not only one of the most power-
ful cars around, but also one of the
cleanest. One pair of sensors is
used to monitor the oxygen levels
in each of the twin exhaust tracts.
An additional pair of sensors* –
again, one on each tract – is
located downstream from the cat-alytic converters. This information
is used by the engine management
system to monitor the efficiency of
the catalysts.
Fuel.
The current Porsche sportscar
model range is already compatible
with fuels that have an ethanol
content of up to 10 %. A ‘biofuel’
made from naturally replenishing
materials, ethanol has a positive
impact on the carbon dioxide bal-
ance since the plants grown for its
production also absorb carbon
dioxide from the atmosphere.
Fuel system.
In the fuel supply system, we’ve
minimised the evaporation of
hydrocarbons. This is achieved
through a combination of active
carbon filter and special fuel-tank
coating. All fuel lines are made
from aluminium, while those
carrying vapours are made from
multi-layer plastic.
* Not featured in markets with leaded fuel.
Noise.
The 911 GT2 complies with all
noise regulations in the respective
markets. Rather than resorting
to engine encapsulation, we’ve
eliminated noise at source. All that
remains are the powerful acoustics
you’d expect from a thoroughbred
Porsche.
Servicing.
Longer service intervals are not
only easier on resources, they also
reduce ownership costs.
For service intervals of the 911 GT2,
please refer to the price list.
In an era of intensifying debate
about CO
2emissions, every auto-
motive manufacturer is considering
how to deal with the question of
fuel consumption. Our answer has
long been the same: maximum
efficiency.
Porsche reduces the CO2emissions
of its vehicles annually by an aver-
age of 1.7 %. In relation to engine
power, Porsche is already among
those manufacturers achieving the
lowest CO
2emissions. This has
been achieved through an efficient
drive concept, optimised aero-dynamics, low rolling resistance
and lightweight construction.
This high degree of environmental
responsibility is clearly demonstrated
by our approach to environmental
management at the Porsche
development centre in Weissach.
Powerful performance needn’t cost the earth.
