2011 PORSCHE 911 CARRERA suspension

Many legends look to the past.
This one looks to the future.

The new 911.
At the beginning, we took time to reflect
on where we came from and, above all,
where we want to be.
One thing was clear. To be able to build
the new 911, we would need to find the
right answers. What is it that defines us?
The engineering credentials as suggested
by the ‘Dr. Ing.’ in our company name,
certainly. More than 28,000 racing victo -
ries, definitely. Not just feats of heroism
any longer, but responsibilit y for the future
of the sports car and for the environment.
Then there is our reputation as an iconic
sports car manufacturer. However, this
reputation means nothing unless we con -
tinue to breathe new life into old ideas. For us, heritage and future are inseparably
linked. Of course, we could simply have
made a capable sports car, but this wouldn’t
have been a Porsche, and certainly not
a 9 11 .
Our identit y is the 911. This is especially
true, even in the 21st century. Instantly
recognisable and originally engineered
for the racetrack, it continues to stir the
emotions today, just as it did in 1963.
Yet, is that enough to move forward?
Above all, is it enough for you? Don’t we
need to break the stranglehold of tradition
once in a while before it one day stifles
innovation altogether? We believe that
the answer is ‘yes’, which is why no fewer
than 90 % of the components of the 911
are either new or have been fundamentally
revised. This is our approach to the preser -
vation of tradition. It is precisely how we

respond to the passion for the sports car
and do justice to the 911 legend, and
always with tomorrow in mind.
We have achieved this with a brand new
design and a longer wheelbase, with
refined engines that consume less fuel
but deliver more power, with efficiency-
enhancing technologies such as auto
start /stop, thermal management and
electrical system recuperation, with an
intelligent light weight body that uses a composite blend of aluminium and steel
and a new hood concept on the Cabriolet
models, with a suspension derived from
motorsport, and with a progressive interior
designed for sporty comfort.
All of that is what defines us. In short, it
is the way in which we combine tradition
and innovation, performance and everyday
practicality, form and function. For us,
these are not contradictions, but our
motivation. We are referring to Intelligent
Performance.
Our identit y can be accurately described
by many words, and by one number.

Its identity emerged on the racetrack.
Its home is on the road.

The new 911 Carrera S.
Nothing defines us more than our heritage.
It says a lot about who we are. This is
particularly true of the new 911 Carrera S,
which has all the characteristics you would
expect of a sports car whose origin is in
motorsport.
An elementary component of its DNA,
therefore, is power in the form of a 3.8-litre
engine with direct fuel injection (DFI) and
VarioCam Plus. It delivers 294 kW (400 hp)
at 7,400 rpm, and the maximum torque
of 440 Nm is achieved at 5,600 rpm. In
conjunction with the manual gearbox, the
sprint from 0 to 100 km/h (0 to 62 mph) is
completed in just 4.5 seconds. Top speed
isn’t reached until 304 km/ h (188 mph).
On figures alone, the new 911 Carrera S
excels, particularly in terms of efficiency.
Fuel consumption and CO2 em issio ns
have been reduced by 15 % compared

with the previous model. This has been
possible thanks to the auto start /stop
function, which is available as standard,
and the coasting function in conjunction
with the optional Porsche Doppelkupplung
(PDK).
It ’s not difficult to tell where the
911 Carrera S comes from. You can hear
it in the resonant engine sound and you
can see it in the t win tailpipes in brushed
stainless steel and 20 - inch Carrera S
wheels. You can also feel it, thanks to Porsche
Active Suspension Management (PASM),
which is fit ted as standard, or the optional
PASM sports suspension with sport y

aerodynamics and the ride height lowered
by 20 mm. Or the optional Sport Chrono
Package and dynamic engine mounts.
Available as standard, Porsche Torque
Vectoring (PTV), or Porsche Torque
Vectoring Plus (PTV Plus) in conjunction
with the optional PDK, increase traction.
Porsche Dynamic Chassis Control (PDCC),
the active roll stabilisation system, is
available as an option and improves agility,
comfort and safet y. On the subject of safet y, the brakes at
the front of the new 911 Carrera S come
equipped for the first time with monobloc
fixed calipers with six instead of four

pistons for improved braking performance
and a shorter braking distance. Bi-Xenon
headlights are standard and the Porsche
Dynamic Light System (PDLS) is available
as an option.
There is no doubt. The new 911 Carrera S
knows its roots, and embraces them with
efficiency, power and sporty performance.

“That can’t be done.”
If ever a sentence gave motivation to sports car designers, this is it.

Chassis and body.
A solid identit y tends to be described
with words like stability, directness or
substance. This might sound a lit tle
serious but, when it comes to the chassis
and body, we think that this is entirely
the right approach.
The best example is the engineered
design. Indeed, dynamic per formance
and ride comfort fundamentally depend
on factors such as vehicle weight, body
rigidity, wheelbase, axle construction
and steering. With the new 911, we
challenged our engineers to push the
boundaries of what is possible. Chassis control systems make a key

contribution to the 911 driving experience
and thus to the 911 identit y. These
include Porsche Stability Management
(PSM), Porsche Active Suspension
Management (PASM), which comes as
standard in the 911 Carrera S models,
Porsche Torque Vectoring Plus (PTV Plus).
Porsche Dynamic Chassis Control (PDCC)
is additionally available as an option for
the 911 Carrera S.
Yet, there is still scope for improvement
as far as sport y performance is
concerned. The optional Sport Chrono
Package triggers an adrenaline rush
at the push of a but ton. Dynamic engine
mounts, until now exclusively reserved
for 911 GT and Turbo models, may not be
capable of breaking the laws of physics
but they do succeed in exploiting them
to their own advantage – and yours.

Engineered design.
The new 911 fulfils two structural design
requirements thanks to its completely new
bodyshell: first, excellent driving dynamics
due to the body’s extremely high rigidit y;
second, a vehicle weight saving of up to
60 kg primarily as a result of the intelligent
lightweight construction.
To meet the second requirement,
we employed innovative and precise
techniques for combining various materials
in order to utilise specific material
properties exactly where they are needed.
For the bodyshell, therefore, we used
very thin, but nevertheless extremely
rigid, sheets of steel. Aluminium and magnesium were used extensively in
areas such as the roof, underbody, front
end, doors, rear wings and engine com
-
partment and luggage compartment lids.
Magnesium, which is a particularly light -
weight material, was also selected for
the cockpit and centre console support
beam and, in the Cabriolet models,
the hood shell elements. Such material efficiency is key to reducing the overall
weight and, as a result, fuel consumption
of the vehicle.
For the driver, this intelligent blend

of materials reduces the weight of the
vehicle and offers a high level of comfort
thanks to excellent vibration-damping
characteristics and particularly high com -
posite rigidit y, an increase in dynamic
torsional stiffness of up to 25 % compared
with that of the previous model, and
even
sportier handling despite a further
improvement in the weight to power ratio.
The 100 mm longer wheelbase improves
comfort as well as straight-line accuracy
and driving stabilit y at high speeds and in
fast corners.

Front and rear axles.
The redesigned independent suspension
at the front features a light weight spring-
strut axle with longitudinal and transverse
links and cross members that have been
refined for stiffness. Each front wheel
is precisely located, ensuring excellent directional stability, superior handling
and reduced pitching under braking, and
the wider track optimises turn-in.
The rear axle is equipped with a

motorsport-derived multi-link suspension
and chassis subframe. Refined axle kine -
matics for improved longitudinal damping
reduce acceleration squat and increase comfort. Light weight spring struts further
enhance agility.
The high proportion of aluminium used in
the construction of the axles reduces the
weight of the vehicle and of the unsprung
masses, helping to improve fuel economy,
comfort and agility.

PASM, the electronic damping control
system, is standard in the 911 Carrera S
models and available as an option for
the 911 Carrera models. It actively and
continuously regulates damping forces
according to driving st yle and road
conditions. In addition, the suspension
is lowered by 10 mm.
PASM has t wo modes, which can be
selected using a separate but ton on
the centre console: ‘Normal’, which is a
blend of performance and comfort, and
‘Sport ’ where the setup is much firmer. Sensors record the body movements

that accompany powerful acceleration,
braking or uneven road surfaces. In
the new 911, the number of sensors
has been increased for improved data
acquisition and more ef ficient control
interventions. The PASM control unit eval -
uates the driving conditions and modifies
the damping force on each of the wheels
in accordance with the selected mode.
In ‘Sport ’ mode, the suspension is set to
a harder damper rating. On uneven roads,
PASM immediately switches to a softer rating, thereby improving contact
bet ween the wheels and the road.

When the road surface improves, PASM
automatically reverts to the original,
harder rating. If ‘Normal’ mode is selected
and the driver’s st yle becomes more
assertive, PASM automatically switches
to a harder rating. Damping firms up,
and driving stabilit y and road safet y are
increased.
The results are tangible: increased
driving stability, improved comfort and
enhanced performance.
No need to let the laws of physics
spoil your fun.

Porsche Active Suspension Management (PASM).PASM sports suspension.
The new PASM sports suspension is
available as an option for the 911 Coupé
models in conjunction with 20-inch wheels
and Porsche Torque Vectoring (PTV) or
Porsche Torque Vectoring Plus (PTV Plus). The ride height is 20 mm lower than

with the standard suspension or 10 mm
compared with the PASM suspension.
The springs are harder and shorter, and
the anti-roll bars on the front and rear
axles are stiffer. The front spoiler lip has
a more sport y geometry, the rear spoiler extends even further. These not only

further reduce lift at the front axle, but
also provide downforce at the rear axle
for improved aerodynamics and even
better performance.

Electromechanical power steering.
Another possible definition of efficiency
is a system that works only when it is
needed, and then does so in a particularly
effective way.
This was the guiding principle for our
engineers in the development of the new electromechanical power steering.
Statistics show that a car drives in a
straight line 90
% of the time. Unlike
conventional hydraulic pumps, the electric
motor uses energy only when the steering
wheel is actually turned. The absence
of hydraulic fluid also makes the system
more beneficial to the environment.
As far as the other 10 % is concerned, we’re
optimally prepared as the steering system
is t ypically Porsche. It features a variable
steering ratio and responds sensitively
and directly at the same time as providing
customary agility, a high level of comfort
and precisely selected feedback from the
road. Our definition of efficient.Power steering Plus.
Power steering Plus, the comfort-enhancing
power-steering system, is available
as an option for the 911 Carrera models.
At high speeds, the steering is as firm as
you would expect and responds with
extreme precision while steering comfort
remains as high. At low speeds, the steering
ratio of Power steering Plus adjusts for
much easier manoeuvring and parking.
SPORT button.
Fit ted as standard, the new SPORT
but ton enables you to select a suspension
setup where the emphasis is on either
comfort or sport y performance. At the
push of a button, the electronic engine
management system switches the engine
mapping to offer an even sharper
response and engine dynamics that are
more direct.
In vehicles with Porsche Doppelkupplung
(PDK), upshifts take place at higher
engine speeds and downshifts happen sooner. In addition, coasting mode and
the auto start/stop function are automati
-
cally deactivated. If fitted, the optional
sports exhaust system is also activated
automatically.
Sport Chrono Package.
The Sport Chrono Package including
dynamic engine mounts is available
as an option. This integrated system
provides simultaneous enhancement for
the chassis, engine and transmission.
Every day can be sports day.

Included in the package are a performance
display, a digital and an analogue stop -
watch and the SPORT PLUS but ton. An
additional display in the steering wheel
and instrument cluster indicates whether
the SPORT but tons and Launch Control
have been activated.
On activation of SPORT PLUS mode,
Porsche Active Suspension Management (PASM) and, in the S model, optional

Porsche Dynamic Chassis Control (PDCC)
switch to a harder damping set ting
and offer more direct steering and,
therefore, better road holding.
In SPORT PLUS mode, the trigger thresh -
old
for PSM is raised. Agilit y is perceptibly
enhanced when braking for corners with
PSM, allowing sportier braking and exit acceleration. For maximum dexterit y,
PSM can be set to standby while the car
is still in SPORT PLUS mode. For safet y,
it is set to intervene automatically only
when ABS assistance is required on
both the front wheels.
In combination with PDK, the Sport
Chrono Package has t wo additional

functions for a sport y drive that borders on a motorsport experience. The first

is ‘Launch Control’, which can be used
on the track to achieve the best possible
standing start – a racing start.
The second function is the ‘motorsport-
derived gearshif t strategy’. Using this,
Porsche Doppelkupplung (PDK) is geared
up for extremely short shift times and
optimum shift points for the maximum
acceleration available. This combination
of uncompromising and involving perfor -
mance is ideal for the racetrack.
A key component of the Sport Chrono
Package is the stopwatch mounted on
the dashboard. In conjunction with PCM,
a special performance display enables
you 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.
A feature of the Sport Chrono Package
borrowed from motorsport is the dynamic
engine mounts. These exploit the laws
of physics for your own driving pleasure.
Dynamic engine mounts.
You don’t have to take the new 911 onto
the racetrack. But you can, more so
than ever, because dynamic engine
mounts are now included as part of the
Sport Chrono Package. Based on the
engine mounts of the 911 GT3 and
911 Turbo models, it is the first time that they have been available for a

911 Carrera. Even if track racing is not
for you, dynamic engine mounts make
a decisive contribution to dynamic
performance on the road, too.
The electronically controlled system mini -
mises the oscillations and vibrations of the
entire drive train, especially the engine, and combines the benefits of a hard or
soft engine mounting arrangement.
A hard engine mounting delivers optimum
dynamic performance because it offers
the highest degree of handling precision
possible. Soft engine mounts, on the
other hand, minimise oscillations and
vibrations. While comfort is improved on
uneven road surfaces, this comes at

the expense of dynamic performance.
Our engineers have solved this problem
by enabling the engine mounts to adapt
their stiffness and damping properties to
changes in driving st yle and road surface
conditions. This has been achieved by
use of a fluid with magnetic properties in interaction with an electrically generated
field. For the driver, the results are tangi
-
ble. Handling is perceptibly more stable
under load change conditions and in
fast corners. Whenever a less assertive
driving st yle is adopted, the dynamic
provide a higher level of comfort.

Our identity is found under the bonnet,
in the design and behind the steering wheel.

Comfort.
Driving a 911 is first and foremost about
the feel of the road in the original, unadul -
terated and direct sense. Is it possible,
then, to mention the 911 and comfort in
the same breath? To speak of systems
that make driving ‘more agreeable’, or of
materials that feel ‘pleasant ’ to the touch?
Good question.
In reality, however, should anyone really
be forced to choose one over the other?
Let ’s introduce ourselves to the concept
of sport y comfort – dynamic performance
that maintains composure even when
pushed to the extreme.
Interior.
Engineering and st yle – and Porsche
identit y on the inside, as demonstrated by
the new elevated centre console. In t ypical
Porsche fashion, the use of form follows
a basic principle: focus on the driver. This
is why the distance bet ween the gear lever
or selector and steering wheel is extremely
short and the operating logic, such as that
of the two-zone air conditioning system
or the suspension set tings, is clear and
uncomplicated. You shouldn’t have to
browse one submenu after another. You
should instead be able to concentrate
on what ’s important: the road.
Inside there is a range of high qualit y
materials used, including a full leather
interior as standard. Alcantara has
proven its worth in motorsport and is
used as standard for the rooflining of
the Coupé models.
In addition to the choice of Black, Plati -
num Grey, Luxor Beige and Yachting Blue
for the interior, there is a wide range of
other personalisation options available,
including two-tone colour combinations
or special colours and materials such as
carbon, aluminium or high quality wood.
