ESP PORSCHE 911 GTS 2010 5.G Information Manual

Engineering.
The new 911 Carrera GTS.
More power. Maximum torque is
reached earlier. An even faster
throt tle response and even
better acceleration. An even
sportier driving experience.
These are the most compelling
at tributes compared with the
911 Carrera S models.
The figures say it all. The upra­
ted 3.8­litre flat ­six engine with
direct fuel injection (DFI) now
delivers 300 kW (408 hp), 23 hp
more than the 911 Carrera S.
The Coupé model completes the
0 to 100 km/ h (62 mph) sprint
in 4.6 seconds, the Cabriolet in
4.8 seconds.
Yet, there has been no increase
in fuel consumption or emissions.

This is not a contradiction, but a
combination of dynamics and
efficiency, of sportiness and
ever yday practicalit y. In short, it
is our understanding of the
sportscar concept. We call it
Porsche Intelligent Per formance.
Increased per formance, with
ideas that drive us for ward –
a principle that also reflects
our approach to the chassis
and to safet y. Both models are
equipped as standard with
Porsche Active Suspension
Management (PASM) and

Porsche Stabilit y Management
(PSM). The optional Sport Chrono
Package Plus is the essence of
motorsport, of fering an even
more dynamic tuning of the
chassis and engine setup. In
conjunction with the optional
Porsche Doppelkupplung (PDK),
the Sport Chrono Package Plus
delivers a further improvement
in acceleration: 4.2 seconds

for the Coupé and 4.4 seconds
for the Cabriolet. Gear changes
take place in milliseconds,
with no interruption in the flow
of power. Together, this spells
911 Carrera GTS.
Design.
Three words are enough to
make a clear statement: athletic,

muscular, powerful. The look of
the new 911 Carrera GTS models
leaves no room for doubt. They
are models of clarit y.
Let ’s get straight to the detail,
beginning with the dynamically
accentuated cooling air intakes
in the front apron and the
additional spoiler lip with a
black painted finish. These are
distinctly sport y characteristics,
with components that have
been optimised in the Porsche
wind tunnel to improve aero ­
dynamic ef ficiency. On the sides
of the vehicle, black sideskirt
trims are a bold indication of
the performance in store. The rear end is just as expres
­
sive. Compared with the
911 Carrera S, the body is
44 mm wider at the rear axle
and the rear track has been
widened by 32 mm for greater
roll stabilit y and improved
turn ­in. The 911 Carrera GTS
models are fit ted with 19 ­inch
RS Spyder wheels featuring
a central locking device. Until
now, this racing wheel design
was exclusive to the 911 Turbo.
The black painted finish on
the centre spokes is also an
unmistakable reference to
motorsport, and a clear signal
of the driver’s racing mentalit y.

Engine.
The message is clear and
un mistakable: force, power
and dynamics. With direct fuel
injection (DFI) and VarioCam
Plus, the uprated 3.8­litre six ­
cylinder rear engine of the
new 911 Carrera GTS models
generates 300 kW (408 hp) at
7,300 rpm.
Words aren’t that important
when something speaks to you from the soul.
Maximum torque is 420 Nm
and both models achieve a top
speed of 190 mph (306 km/ h).
The Coupé accelerates from
0 to 62 mph (100 km/ h) in
4.6 seconds, the Cabriolet in
4.8. The optional Porsche
Doppelkupplung (PDK) further
improves acceleration, reducing
these times to 4.4 and 4.6 sec ­
onds respectively. The throttle response is even
more direct and acceleration is
even sportier. The engine power
is 23 hp higher than that of the
911 Carrera S. This was made possible by the redesigned
intake manifold, the modified
cylinder heads and the opti
­
mised engine electronics.
‘ It has a truly insatiable urge for acceleration, but with 408 hp
at the rear axle and such a tremendous amount of grip, that’s
no surprise.’
August Achleitner, Director Product Line Carrera

Intake manifold.
Take a deep breath. The
911 Carrera GTS models are
fit ted with a variable resonance
intake system featuring six
switchable, vacuum­controlled
valves. In the direct injection system,
the EMS SDI 3.1 engine manage
­
ment system adjusts the
injec ­
tion timing individually for
each
cylinder and the injection quanti ­
t y for each cylinder bank. This
optimises both the combustion
curve and fuel consumption.
A hot ­film air mass meter takes
care of the airflow, so that the
combustion chambers contain
exactly the right mixture at all
times.
Dual injection is implemented
at engine speeds of up to
3,200 rpm and triple injection
up to 2,500 rpm. The required
quantit y of fuel is distributed
to t wo or three successive
injection processes per cycle.
These valves enable the system
to switch bet ween power
­ and
torque ­optimised geometries
for all six air intake tracts to
produce even higher torque in
the mid ­rev range. The improved
charging of the combustion
chamber is made even more
This strateg y achieves faster
heating of the catalytic con­
verters af ter a cold start and
produces greater torque in the
upper load range.
DFI improves the internal cool
­
ing of the combustion chamber
by forming the mixture directly
in the cylinder. This has made it
possible to increase compres ­
sion (12.5:1), resulting in more
engine power and even greater

Injection is regulated by the
electronic engine management

cleaning system ensures that
emissions remain below the
strict limits of the Euro 5 emis ­
sion standard, thus helping to
protect the environment.

­optimised
intake duct. The cooling system
has been adapted to the
increased engine output.
VarioCam Plus.
VarioCam Plus is a variable
valve timing system on the
inlet side which also features
t wo ­stage valve lif t. This allows
even smoother running with
comparatively efficient fuel
consumption and low emissions
– yet with greater power and
torque.
This t wo­in ­one engine concept
seamlessly adapts in response
to driver input. The result
is instant acceleration and
extremely smooth running

Direct fuel injection (DFI).
Ef ficiency is about get ting more
from less, and direct fuel injec ­

With millisecond precision,
DFI injects fuel at up to 120 bar

Porsche Doppelkupplung
(PDK).

PDK is available as an option for
the new 911 Carrera GTS mod­
els. Gear changes take place in
milliseconds, for vastly improved
acceleration and lower fuel con ­
sumption.
In total, PDK has seven gears at
its disposal. Gears 1 to 6 have a
sports ratio, with the top speed
being reached in 6th gear. The
7th gear has a long ratio and
Six-speed manual gearbox.

Accurate and involving: the six ­
speed manual gearbox is the
link to each and every gear.
The cable ­operated gearshif t
unit is designed for optimum
progression through the gears
and the gear lever is insulated
from the engine and gearbox.
With minimal resistance, the
gear lever throw is short and
precise, enabling a rapid gear ­
shif t action and positive
response. helps to reduce fuel consump
­
tion even further. PDK is essen ­
tially t wo half gearboxes in one
and thus requires t wo clutches –
designed here as a double wet
clutch transmission.
This double clutch provides an
alternating, non positive connec­
tion bet ween the t wo half gear ­
boxes and the engine by means
of t wo separate input shaf ts (input shaf t 1 is nested inside
the hollowed
­out input shaf t 2).
The flow of power from the
engine is only ever transmit ted
through one half gearbox and
one clutch at a time, while the
next gear is preselected in the
second half ­gearbox. During
a gear change, therefore, a
conventional shift no longer
takes place. Instead, one clutch
simply opens and the other
closes at the same time. PDK and the manual gearbox
deliver power directly to the
road. With the optional Sport
Chrono Package Plus (p. 26),
you can make it even more
direct, and even sportier. With a
rush of adrenaline and euphoria,
you are straight into the action.
Precise actions hit the mark sooner.
The same is true of our transmission concepts.

Key features include a digital
and analogue stopwatch, the
SPORT button, a performance
display, a personal memory
function in the Porsche Commu­
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.

even sportier tuning of the
engine and chassis, and delivers
even greater driving pleasure as
a result.
A harder rev ­limiter 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 ­
er, brake ­induced 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 ­
al dynamics. Agilit y is enhanced
when braking for corners with
PSM enabling greater manoeu ­
vrability under braking and exit

‘Launch’ mode from the accel­
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.

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
­
cantly more immediate and a
harder rev ­limiter is also applied
in the higher gears. The second function is the
‘motorsport
­derived 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 ­
mising and involving perform ­
ance is ideal for the racetrack.
Another key component of the
Sport Chrono Package Plus is
the stopwatch mounted on the
dashboard. Porsche Communi ­
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

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

Braking system.
Porsche brakes are widely
renowned for their stability, per­
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 ­
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 diame­
ter of 330 mm front and rear –
for formidable braking perform ­
ance. Their cross ­drilled design
improves behaviour in wet
conditions. The discs are also
internally vented for bet ter
heat dispersal. Other features
include a powerful nine ­inch vac­
uum brake booster for reduc ­
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 high­vacuum 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 ­
sional stabilit y. The ceramic
material is totally resistant to
corrosion and of fers excellent
acoustic damping properties.
The pads are mounted in six ­
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 ­
meter of 350 mm front and
rear. The discs are made from
a specially treated carbon ­fibre
compound that is silicated in four
­piston 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 ­
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
­
tional high ­per formance braking
systems, we recommend that
all brake components be profes ­
sionally inspected and replaced
where necessary after every
track event.

Fog lights.
Bi­Xenon 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 acce­
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 ­
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

determines the angle of illumina ­
tion for the dipped beam lights,
up to a maximum of 15 degrees.
On t wisting roads, this means

obstacles can be seen earlier
by the driver.
Driver and passenger airbags.
The t wo full ­size airbags can be
inflated in t wo stages, depend
ing
on the severit y of the impact. In
a low ­speed crash, the airbags
are only partially inflated, there ­
by minimising discomfort to the
occupants.
Porsche Side Impact
Protection System (POSIP).
The Posche Side Impact
Pro
tection System (POSIP), fit ­
ted as standard, consists of side
impact protection beams in the
doors and t wo side airbags on
each side, namely a thorax air ­
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 ­absorbing
steering column, three ­point
seat belts with height adjust ­
ment (Coupé models only), seat
belt pre ­tensioners and force
limiters and energy ­absorbing
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 ­over
protection system if the car
were to overturn. Two spring ­
loaded roll ­over bars are neatly
incorporated behind the rear
seats. The roll ­over sensor
continuously monitors the car’s
pitch and roll, contact with the
road, as well as lateral and lon ­
gitudinal forces. If the car were
to overturn, the roll ­over bars
would be deployed instantly.

Instruments.
Time is precious, so you want to
be able to see where every thing
is at a single glance. This is
why the instruments of the new
911 Carrera GTS models have
been designed with sport y driv­
ing in mind.
Those who speak in clear language
want a clear response.
The five circular instruments
with dial faces in black give you
all the important information
you need ef ficiently and accu ­
rately. The integrated on
­board com­
puter displays your average fuel
consumption, speed and range
until empty.

Navigation module.
The optional GPS navigation
system has a hard drive contain­
ing map data for most European
countries, allowing for rapid
route calculations with a choice
of three alternative routes.
When viewing a map, it is pos­
sible to select bet ween a 3D
perspective and a 2D display,
enhanced by the addition of
altitude profiles. In splitscreen
mode, you can choose to dis ­
play not only the current map
overview, but also a list of icons
that represent the next driving
manoeuvre.
Telephone module.
The optional quadband GSM
telephone module offers con­
venience and excellent recep ­
tion. By inserting a SIM card
directly into the PCM’s integral
SIM card reader, calls can be
made using the hands ­free
facilit y. For even more
convenience, the Bluetooth
®
capabilit y of a mobile phone
can be used to make calls via
the SIM Access Profile (SAP).
1)
Once automatic pairing is com ­
plete, the mobile phone’s aerial
is switched of f to conserve
battery charge and the phone
operates via the car aerial.
Depending on the mobile phone
model, this gives access not
only to the numbers on the SIM
card, but also to the phone’s
internal memor y. Depending on
the phone, it can also be con ­
trolled using PCM, the optional multifunction steering wheel

or the optional voice control
system, without it ever leaving
your pocket.
In conjunction with the optional
navigation module, the tele ­
phone module also enables you
to establish a Bluetooth® link
with those mobile phones that
only support the Handsfree
Profile (HFP). In this case, the
GSM connection is always
established through the aerial
of the mobile phone.
2) PCM acts
as a hands ­free system and
you can leave the mobile phone
tucked away.
On request, a cordless handset
for the telephone module is also
available. However, the handset
cannot be used for Bluetooth
®
links established using the
Handsfree Profile (HFP).
Mobile phone preparation.
To enable a Bluetooth® connec­
tion for those mobile phones
that only support the Handsfree
Profile (HFP), an optional mobile
phone preparation is available
(with or without a bracket).
1)
With HFP, PCM acts merely
as a hands ­free system and the
mobile phone can remain tucked
away. Only the basic phone
functions can be operated using
PCM. The GSM connection is
established through the aerial
of the mobile phone.
3)
Voice control system.
Almost all of the functions of
PCM can be controlled via the
optional voice control system,
which recognises commands or
number sequences, irrespective
of the speaker, and there is
no need to ‘ train’ the system.
Universal audio interface.
Also available as an option is
the universal audio inter face.
This enables you to connect
you r i Pod
®, a USB stick/MP3
player or any other compatible
audio source of your choice.
The iPod® or USB stick can
be operated conveniently and
safely via PCM.
