At Porsche, sound will always
be crucial to the design concept.
The sports exhaust system is
characterised by audible and
also visible hallmarks: power ful,
resonant and unadulterated.
The tailpipes have a nanocoated,
polished finish on the inside, and
a black painted finish on the out Â
side. For contrast, the rear trim
panel between the tailpipes is
also finished in black. Whilst the 911 Carrera GTS
models are part of the 911 range,
they explore a dif ferent direc Â
tion. As an expression of this
individualit y, the air filter casing,
rear end, door sill guards and
doors all carry the ‘Carrera GTS’
logo.
The interior focuses on the
essentials. These models are
all about sport, so there is no
place for unnecessar y weight.
Such as the rear seats, which
we have deleted from the Coupé
model. If you think
differently, it
is available to order at no extra
cost. The three
Âspoke ‘SportDesign’
steering wheel is not only
standard, it is exclusive to the
new 911 Carrera GTS models.
It is both minimalist and func Â
tional, for even sportier appeal.
Materials are important. They
make a distinct first impression:
excellent functionality and
an authentic motorsport feel.
Alcantara – nonÂslip, washable
and easy to maintain – covers
the steering wheel, the gear
and handbrake levers, the seat
centres and, in the Coupé,
the rooflining. This material is
designed to cope with the
stresses of heav y use. Just
like the sports seats, which
of fer firm lateral support in any
driving situation.
The greatest challenger in sport
is, ultimately, oneself. This was
the starting point for our devel Â
opment of the 911 Carrera GTS
models. We have made them
leaner and more muscular, giv Â
ing a more distinctive contour.

Pitching of the body when pullÂ
ing away and braking is minimal,
as is body roll in corners. Tyre
noise and vibrations are simiÂ
larly reduced. Driving stabilit y,
on the other hand, is extremely
high.
This purposeful lightweight
construction keeps the vehicle
gross weight and the weight of
the unsprung masses low, while
the suspension itself allows
even high
Âspeed manoeuvres
to be executed smoothly and
s a fe l y.
Wheels.
As standard, the new
911 Carrera GTS models are
fit ted with 19 Âinch RS Spyder
wheels with centre spokes
with a black painted finish.
The main feature of these forged
aluminium alloy wheels is the
central locking device – a clear
reference to the world of
motorsport. Compared with the
conventional five Âbolt wheel
connection, it offers enhanced
driving dynamics and perform Â
ance thanks to the reduction in
rotating masses.
Tyre Pressure Monitoring,
available as an option, sends
warnings to the on Âboard com Â
puter’s display screen in the
event of a gradual or sudden
loss of pressure.
Porsche Active Suspension
Management (PASM).
Included as standard equip Â
ment, Porsche Active Suspen Â
sion Management (PASM) is
an electronic active damping
system. It of fers continuous
adjustment of the damping
force on each wheel, based on
the current driving situation
and your driving st yle.
At the press of a button, the
driver can select bet ween t wo
different modes: ‘Normal’, which
is a blend of performance and
comfort, and ‘Sport ’, where
the setup is much firmer. The
balance bet ween comfortable
and uncompromisingly sporty is struck more ef fectively than
with a conventional chassis. The
PASM control unit evaluates the
driving conditions and modifies
the damping force on each of
the wheels optimally in accord
Â
ance with the selected mode.
Sensors monitor the movement
of the vehicle body, for exam Â
ple, under heav y acceleration
and braking or on uneven roads.
The control unit tunes the damp Â
ers to the optimum hardness
for the selected mode to reduce
roll and pitch and to increase
contact bet ween each individual
wheel and the road.
PSM computes the actual
direction of motion. If this direc Â
tion deviates from the desired
course, PSM can, for example,
initiate braking interventions
targeted at individual wheels in
order to stabilise the vehicle.
Porsche Stability
Management (PSM).
PSM, which comes as standard,
is an automatic control system
that stabilises the vehicle at the
limits of dynamic driving per Â
formance. Sensors continuously
monitor driving direction, speed,
yaw velocit y and lateral acceler Â
ation. Using this information, Under acceleration on wet or
low
Âgrip road surfaces, PSM
improves traction using the ABD
(automatic brake dif ferential)
and ASR (anti Âslip regulation)
functions. For a pure, active
driving experience, PSM can
be deactivated but it will auto Â
19Âinch RS Spyder wheel with central locking device
matically reactivate if necessar y
for safet y.
PSM comes with t wo additional
functions: precharging of the
brake system, enabling the
maximum braking power of the
911 Carrera GTS to be achieved much sooner; and brake assist,
for maximum deceleration in a
critical situation.
Those who speak in clear
language want clear distinctions.

Key features include a digital
and analogue stopwatch, the
SPORT button, a performance
display, a personal memory
function in the Porsche CommuÂ
nication Management (PCM),
and – in combination with
Porsche Doppelkupplung (PDK) –
the SPORT PLUS but ton, and an For maximum dexterit y, PSM
can be set to standby while
the car is still in ‘Sport ’ mode.
For safety, it is set to intervene
automatically only when ABS
assistance is required on both
of the front wheels.
In combination with PDK, the
Sport Chrono Package Plus has
two additional functions that
are activated by pressing the
SPORT PLUS button, for a
sport y drive that borders on
a motorsport experience.
The first function is ‘Launch
Control’ which, for example
when performing laps, helps you
achieve optimum acceleration
from a standing start – a racing
start in other words.
Sport Chrono Package Plus.
Sport Chrono Package Plus is
available as an option. It of fers
even sportier tuning of the
engine and chassis, and delivers
even greater driving pleasure as
a result.
A harder rev Âlimiter is also
applied in the automatic mode
of the optional PDK, while the
gearshif t points are delayed
until the upper rev range. The
shif t times are shorter, the gear
changes sportier. Even at low
rates of deceleration and at high
revs, the system initiates a swift Â
er, brake Âinduced downshift.
In manual mode, gear changes
are faster and more dynamic.
In ‘Sport ’ mode, the trigger
threshold for PSM is raised for
increased longitudinal and later Â
al dynamics. Agilit y is enhanced
when braking for corners with
PSM enabling greater manoeu Â
vrability under braking and exit
acceleration, especially at low
speeds. The result? Increased
driving pleasure.
additional display in the steering
wheel which informs the driver if
the SPORT but tons and Launch
Control have been activated.
When the SPORT PLUS but ton
on the centre console is select
Â
ed, the EMS SDI 3.1 engine
management system adapts for The function works like this:
press the SPORT PLUS but ton
when the transmission is in
‘D’ or ‘M’. Then, with your lef t
foot, press the brake pedal
and accelerate fully with the
right foot. The car recognises
‘Launch’ mode from the accelÂ
erator kickdown action and
adjusts the engine speed to the
optimum level, which is around
6,500 rpm. At the same time,
engine torque is increased
and the clutch is applied lightly.
‘Launch Control’ now appears
in the PDK steering wheel dis
Â
play. Now release the brake as
quickly as you can and get ready
to experience all the accelera Â
tion power the 911 Carrera GTS
has to of fer.
sportier per formance driving. In
response to pedal input, a more
dynamic throt tle map opens the
throt tle valve wider than would
be the case in Normal mode.
The throttle response is signifi
Â
cantly more immediate and a
harder rev Âlimiter is also applied
in the higher gears. The second function is the
‘motorsport
Âderived gearshif t
strategy’. Using this, Porsche
Doppelkupplung (PDK) is geared
up for extremely short shif t
times and optimum shift points
for the maximum acceleration
available to the 911 Carrera GTS.
This combination of uncompro Â
mising and involving perform Â
ance is ideal for the racetrack.
Another key component of the
Sport Chrono Package Plus is
the stopwatch mounted on the
dashboard. Porsche Communi Â
cation Management (PCM) has
a special performance display
to view, store and evaluate lap
times or other driving times.
It shows the total driving time,
lap distance, lap number and
lap times recorded so far. You
can view the current fastest lap
Also influenced by ‘Sport’
mode is the standard equipped
Porsche Active Suspension
Management (PASM). The
dampers become firmer,
enabling faster turnÂin as well as

and the remaining range until
empt y. Travelled distances can
be recorded and benchmark
times defined.
The personal memor y function
of the Sport Chrono Package
Plus can also be used to store
personalised set tings for a
range of systems, including the
orientation lighting or air condi Â
tioning.

Braking system.
Porsche brakes are widely
renowned for their stability, perÂ
formance and stopping power.
They are designed to cope with
extreme forces and of fer an
appropriately high level of safet y.
The brakes on the 911 Carrera GTS
models are equipped with red four Â
piston aluminium monobloc fixed
calipers. This makes them tough

but light weight and enables a
rapid response and release of
the brake. The pedal travel is
short and easy to control.
The brake discs have a diameÂ
ter of 330 mm front and rear –
for formidable braking perform Â
ance. Their cross Âdrilled design
improves behaviour in wet
conditions. The discs are also
internally vented for bet ter
heat dispersal. Other features
include a powerful nine Âinch vacÂ
uum brake booster for reduc Â
ing pedal effort, and integral
air spoilers for enhanced air
flow in the brake cooling ducts.
‘ At Porsche, safety and extreme performance are always
interlinked. Our brakes are the perfect example.’

a highÂvacuum process at
1,700 °C. The resulting material
is not only much harder than
metal, it is also more resistant
to heat.
Even at high temperatures, the
thermal resistance of the PCCB
discs ensures excellent dimen Â
sional stabilit y. The ceramic
material is totally resistant to
corrosion and of fers excellent
acoustic damping properties.
The pads are mounted in six Â
piston monobloc aluminium
fixed calipers at the front, with
Porsche Ceramic Composite
Brake (PCCB).
Motorsport is the ultimate test
of braking performance. On
request, we can provide you
with a brake system that has
already had to cope with the
harshest requirements of motor
racing – a brake system fit ted
in the cars competing in the
Porsche Mobil 1 Supercup, for
example: the Porsche Ceramic
Composite Brake (PCCB).
The ceramic discs have a dia Â
meter of 350 mm front and
rear. The discs are made from
a specially treated carbon Âfibre
compound that is silicated in four
Âpiston units at the rear. The
resulting brake forces are both
extremely high and remarkably
consistent. The pedal response
is fast and precise with only
moderate input required.
PCCB enables shorter braking
distances in even the toughest
road and race conditions. Excel Â
lent fade resistance ensures
greater balance when slowing
from racetrack speeds.
The key advantage of PCCB is
the total weight saving of
approximately 50 % over metal discs with similar construction
and dimensions. As well as
enhancing per formance and
fuel economy, this represents
a major reduction in both the
unsprung and rotating masses.
This, of course, offers major
benefits in terms of comfort
and road holding on uneven
road surfaces as well as general
handling and agilit y.
Please note that circuit racing,
trackday use and other forms
of per formance driving can
significantly reduce the service
life of even the most durable pads and discs. As with conven
Â
tional high Âper formance braking
systems, we recommend that
all brake components be profes Â
sionally inspected and replaced
where necessary after every
track event.

Fog lights.
BiÂXenon headlights with
dynamic range control are fit ted
as standard. Their beams are
around t wice as bright as those
of conventional halogen lamps.
Light output is improved and the
road illuminated more uniformly
on both dipped and main beam,
helping to minimise driver
fatigue. A headlight cleaning
function is also incorporated.
Dynamic cornering lights.
Available as an option, dynamic
cornering lights offer particularly
effective illumination of the
road ahead, especially through
bends. Sensors continuously
monitor the speed, lateral acceÂ
leration and steering lock and,
from these variables, calculate
the course of the bend. This
Lighting concept.
The front light units incorporate
the direction indicators, the
LED day time running lights and
position lights, which provide
outstanding visibilit y and create
an imposing look that is unmis Â
takable even in the dark. LEDs
are also used for the direction
indicators, the taillights and
brake lights, the additional brake
light in the rear spoiler, and the
rear fog light. LEDs offer several
advantages. Importantly, they
provide effective illumination
and respond more quickly to
driver input.
determines the angle of illumina Â
tion for the dipped beam lights,
up to a maximum of 15 degrees.
On t wisting roads, this means
the course of the road and
obstacles can be seen earlier
by the driver.
Driver and passenger airbags.
The t wo full Âsize airbags can be
inflated in t wo stages, depend
ing
on the severit y of the impact. In
a low Âspeed crash, the airbags
are only partially inflated, there Â
by minimising discomfort to the
occupants.
Porsche Side Impact
Protection System (POSIP).
The Posche Side Impact
Pro
tection System (POSIP), fit Â
ted as standard, consists of side
impact protection beams in the
doors and t wo side airbags on
each side, namely a thorax air Â
bag located in the side of each
backrest and a head airbag
incorporated within each door.
Each airbag has an approximate
volume of 8 litres, ensuring
excellent protection in the event
of side impact.
Additional safet y features
include the headrests which
form an integral part of each
seat, an energy Âabsorbing
steering column, three Âpoint
seat belts with height adjust Â
ment (Coupé models only), seat
belt pre Âtensioners and force
limiters and energy Âabsorbing
elements in the dashboard.
Passive safet y in the Cabriolet.
Despite their modest weight, the
torsional rigidit y and flexural
strength of the 911 Carrera GTS
Cabriolet models are exemplary.
Body flexing is minimal even on
the most poorly surfaced roads.
Additional brace members at
each of the rear wheel arches
provide additional reinforcement
to the bodyshell. Increased
protection is provided by an
automatically deploying roll Âover
protection system if the car
were to overturn. Two spring Â
loaded roll Âover bars are neatly
incorporated behind the rear
seats. The roll Âover sensor
continuously monitors the car’s
pitch and roll, contact with the
road, as well as lateral and lon Â
gitudinal forces. If the car were
to overturn, the roll Âover bars
would be deployed instantly.
