2010 PORSCHE 911 GTS Information Manual

Integrated dry-sump
lubrication.
Integrated dry ­sump lubrication
ensures a reliable supply of oil
even when a sport y driving st yle
is adopted. It also has additional
cooling functions.
The oil tank is located in the
engine, thereby eliminating the
need for an external oil tank.
Four oil pumps remove the oil from the cylinder heads directly
into the oil sump. A fif th pump
in the oil sump directly supplies
the lubricating points in the
engine.
To prevent foaming, the oil is
channelled through cylinders
known as swirlpots. In this
way, optimum lubrication is
guaranteed at
all times. To reduce drive losses and
increase efficiency, an electronic
on
­demand oil pump is used.
This means that the oil pump
is operated at high power when
there is high demand and at
low power when there is low
demand.
The result is an optimised oil
supply appropriate to require ­
ments, lower fuel consumption
and reduced emissions.
Single ­jet piston spray nozzles
cool the piston crowns with oil
from the main lubrication circuit
– another detailed solution that
helps to reduce the thermal
load on the engine. For the engine, these detailed
solutions mean a consistent
supply of oil regardless of gravi
­
tational loads, even in the most
demanding track conditions.

Ignition system.
The ignition system is a static
high­voltage system. Each

individual spark plug has a

separate ignition coil, ensuring
excellent combustion every
time.
Engine cooling system.
DFI and VarioCam Plus enable a
tremendous amount of power to
be produced with comparatively
low emissions, fuel consumption
and noise. The same applies to
our ef ficient cross ­flow cooling
system, as used in motorsport.
Sports exhaust system.
If you want to be heard, it’s bet ­
ter to speak forcefully rather
than loudly.
The sports exhaust system
follows this principle. Fit ted as
standard in the 911 Carrera GTS
models, it makes the t ypical
Porsche sound even more pow ­
erful, even more resonant, and
even more sport y.
The sound varies with driving
behaviour, ranging from a robust output during normal driving to
a distinctly more aggressive
tone during per formance use.
The sports exhaust system is
activated using a but ton on the
centre console.
The look, like the acoustics, has
a clear accent. The tailpipes are
painted black on the outside,
and are polished on the inside.
They are also nanocoated,
which makes them particularly
easy to clean.
90-litre fuel tank.
To increase the distance that
your vehicle can cover on a
tank of fuel, an optional fuel
tank with a refill volume of
90 litres is available in place

of the 67 ­litre tank fit ted as
standard.

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.
20

Front and rear axles.
The independent front suspen­
sion of the new 911 Carrera GTS
models combines McPherson ­
type struts with longitudinal and
transverse links and reinforced
wheel bearings. Each front
wheel is precisely located,
ensuring excellent handling and
directional stabilit y.
To make a simple statement
you don’t need exclamation marks.
At the rear axle, the body is
44 mm wider than that of the
911 Carrera S. This has made
it possible to widen the track by
32 mm for improved dynamic
performance and driving stability,
and faster lateral acceleration
when cornering. The rear axle has a race
­derived
multi ­link suspension, following
the LSA concept (Light weight,
Stable, Agile) for exceptional
driving dynamics. Agilit y is fur ­
ther increased by lightweight
struts with aluminium dampers.
‘ With the 911 Carrera GTS, the only time you’re on shaky ground
is when you start to believe that high performance and everyday
practicality are mutually exclusive.’
Marc Lieb, t wo class victories
in the 24 Hours of Le Mans

Chassis

Pitching of the body when pull­
ing away and braking is minimal,
as is body roll in corners. Tyre
noise and vibrations are simi­
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
­speed 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 ­inch 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 ­bolt wheel

connection, it offers enhanced
driving dynamics and perform ­
ance thanks to the reduction in
rotating masses.
Tyre Pressure Monitoring,
available as an option, sends
warnings to the on ­board com ­
puter’s display screen in the
event of a gradual or sudden
loss of pressure.
Porsche Active Suspension
Management (PASM).
Included as standard equip ­
ment, Porsche Active Suspen ­
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
­
ance with the selected mode.
Sensors monitor the movement
of the vehicle body, for exam ­
ple, under heav y acceleration
and braking or on uneven roads.
The control unit tunes the damp ­
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 ­
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 ­
formance. Sensors continuously
monitor driving direction, speed,
yaw velocit y and lateral acceler ­
ation. Using this information, Under acceleration on wet or
low
­grip road surfaces, PSM
improves traction using the ABD
(automatic brake dif ferential)
and ASR (anti ­slip regulation)
functions. For a pure, active
driving experience, PSM can
be deactivated but it will auto ­

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 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.
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 ­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
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

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 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.
‘Launch Control’ now appears
in the PDK steering wheel dis

quickly as you can and get ready
to experience all the accelera ­

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
­
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

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

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.
