2009 PORSCHE 911 suspension

911 Turbo Cabriolet
Porsche Stabilit y Management
(PSM, page 56) and Porsche
Active Suspension Management
(PASM, page 53) are standard
across the 911 Turbo model
range. The Porsche Ceramic
Composite Brake (PCCB, page
68) is fit ted as standard exclu -
sively on 911 Turbo S models.
Standard on 911 Turbo S and
optional on 911 Turbo models is
the Sport Chrono Package Turbo
with dynamic engine mount
system (page 58). It has a whole
host of performance-enhancing
functions. The ‘overboost ’ on
911 Turbo models, for example,
briefly raises boost pressure
when accelerating in the lower
and mid-engine speed ranges to
provide an additional 50 Nm of
torque. On 911 Turbo S models,
the permanently increased

maximum boost pressure guaran-
tees that a maximum torque
of 700 Nm is available for an
unlimited period.
When combined with PDK, the
SPORT PLUS but ton can activate
‘Launch Control’, for optimum acceleration from a standing
start, or the motorsport- derived
gearshift strategy for racing-st yle
gear changes. The dynamic
engine mount system improves
ride comfort and vehicle
dynamics whilst also providing
more stable handling. The
system reduces the oscillations
and movements of inert masses
in the drive assembly by auto -
matically changing the stiffness
and damping characteristics of
the engine mounts.
As is so t ypical of the 911 Turbo,
comfort and sound are not
neglected either. Porsche
Communication Management
(PCM, page 86), including a
navigation module and 6.5-inch
touchscreen, and the BOSE
®
Surround Sound System both
come as standard. The standard
specification of the 911 Turbo S
models gives you even more,
such as the integrated six-disc
CD/ DVD autochanger, adaptive
sports seats and cruise control.
It sounds, therefore, as though
the 911 Turbo model range has got it all. Apart from weight, that
is. The doors and bonnet are
made of aluminium and the
engine is particularly light weight
thanks to the use of light alloys
and integral dry-sump lubrication.
Forged 19-inch 911 Turbo II wheels
on the 911 Turbo models and
forged
19-inch RS Spyder wheels
with
a central locking device on
the
911 Turbo S models keep the
unsprung masses low. The result
is a power-to -weight ratio of
3.1 kg / hp for the Coupé and
3.3 kg / hp for the Cabriolet
(911 Turbo S models: 3.0 kg / hp
and 3.1 kg / hp respectively).
The technology of the 911 Turbo
and 911 Turbo S models has
enabled a balance to be achieved. It increases power at the same
time as maintaining comparatively
low fuel consumption figures and
CO
2 emissions, showing that,
at Porsche, efficiency and power
are inseparable.

The 911 Turbo.
Although the figures provide
succinct proof of its power,
there is one value in particular
that makes a 911 Turbo what
it is: constancy. Of course, much
has changed in the course of
seven generations, but the basic
principle remains the same.
It is in the nature of the 911 Turbo
to handle its power ef fortlessly
and with composure. Power is
available at all times. The 3.8-litre
six-cylinder boxer engine with
DFI outputs 368 kW (500 hp) be -
t ween 6,000 rpm and 6,500 rpm
and summons up 650 Nm of
torque bet ween 1,950 rpm and
5,000 rpm. Despite delivering
more power than the previous
model, it has been possible to
reduce fuel consumption and CO
2
emissions significantly, by up
to 16 % and 18 % respectively,
depending on the model.
Here are some more fascinating
facts: with the standard six-speed
manual gearbox, the traditional
0 to 100 km/ h (62 mph) sprint is
achieved in just 3.7 seconds.
With the optional PDK and Sport
Chrono Package Turbo with
dynamic engine mount system,
this time is reduced even further,
to 3.4 seconds. The 200 km/ h
(124 mph) mark is reached in 11.9
and 11.3 seconds respectively.
Top speed is 312 km/ h (194 mph).
These figures undoubtedly brand
the 911 Turbo as a super athlete.
Yet the amazing thing is the ease
with which the driver can achieve
them. Helping to make it all
so easy are the standard-fit ted
Porsche Traction Management
(PTM) active all-wheel drive,
Porsche Stabilit y Management
(PSM), Porsche Active Suspension
Management (PASM) and optional
Porsche Torque Vectoring (PT V). What ’s also interesting is that
these technologies not only

produce impressive performance
figures, they also vastly improve
the car’s everyday practicalit y.
The same can be said for the
comfortable interior. Leather

trim and the multi-way electrically
adjustable comfort seats with
driver memory function come as
standard. Porsche Communication
Management (PCM) with a GPS
navigation system features intui -
tive controls, while the standard
BOSE® Surround Sound System
provides an impressive sound
experience. Seat ventilation,
steering wheel heating and many
other personalisation options
are available on request.
The 911 Turbo. Whether you
perceive it as a no -compromise
embodiment of the power

prin ciple or as a technology plat -
form that effortlessly combines
efficiency with comfort and a
sport y edge depends on one thing
above all else: your point of view.
Closed or open, ‘S’ or no ‘S’.
There are many ways to inter -
pret the 911 Turbo concept.
But one thing remains the
same: making a choice never
means making a compromise
on power and efficiency.
You don’t have to depart this life
to become a legend.

The independent front suspension
combines McPherson-type struts
with longitudinal and transverse
links. Each front wheel is pre-
cisely located, ensuring excellent
handling and directional stabilit y. Proven in motorsport, the rear
axle assembly features multi-link
LSA (Light weight, Stable, Agile)
subframe-based suspension. Its
light weight construction of fers
excellent dynamic properties. The
axle kinematics improves stabilit y
under acceleration by reducing excessive compression. The light
-
weight strut has an aluminium
damper instead of conventional
steel to help improve handling
and agility.
The resulting suspension enables
smooth high -speed manoeuvres
in all road and track scenarios.
Pitch and roll are reduced to a
minimum, as are t yre noise and
vibration. The car offers excep -
tionally high levels of stabilit y.

Porsche Active Suspension
Management (PASM).
Included as standard equipment,
Porsche Active Suspension
Management (PASM) is an elec -
tronic active damping system.
It of fers continuous adjustment of
the damping force on each wheel,
based on current road conditions
and driving st yle.
At the press of a but ton, the
driver can choose bet ween t wo modes. While ‘Normal’ mode

provides a blend of performance
and comfort, the ‘Sport ’ setup
mode has a much firmer range of
set tings. The system responds
to changing road conditions and/
or driving st yle by continuously
varying the individual damping
forces within the parameters
defined for the selected setup
mode (‘Normal’ or ‘Sport ’).

Pitch and roll are reduced, whilst
contact of each wheel with the
road is optimised.
What’s the advantage of being well-balanced?
Not letting the smallest thing bother you.
Chassis.
Perhaps the most efficient
way of overcoming everyday
obstacles is to rely on one’s
own experience. No one
knows that better than our
own chassis engineers.

Sport Chrono Package Turbo
with dynamic engine mount
system.
The Sport Chrono Package Turbo
with dynamic engine mount
system is standard on 911 Turbo S
models and available as an
option for 911 Turbo models.

This integrated system provides
simultaneous enhancement for
engine, chassis and transmission.
Key features include a digital
and analogue stopwatch on the
dashboard, a performance dis -
play, a personal memor y function
in the Porsche Communication
Management (PCM), the SPORT
but ton and – in combination with
PDK – the SPORT PLUS but ton,
and an additional display on the
steering wheel which informs the
driver if the SPORT but tons and Launch Control have been acti
-
vated. The 911 Turbo models
additionally of fer the ‘overboost ’
function. This is how it works:
When ‘Sport ’ mode is selected,
the engine management system
creates a much more aggressive
response to pedal inputs. To do
this, it implements an alternative
throt tle map which relates the
pedal position in the foot well to
a wider angle of opening in the
throt tle body. In higher gears, it
uses a hard rev- limiter to protect
the engine under power.
In the 911 Turbo models, under
full acceleration, the maximum
boost pressure in the lower and
medium speed ranges is now
temporarily increased by approx -
imately 0.2 bar. As a result,
engine torque is boosted by 50 Nm to a maximum of 700 Nm for a
limited period. (The 911 Turbo S
models are configured to operate
with a higher boost pressure level,

which means that their maximum
torque is always 700 Nm.)
In addition to the engine, ‘Sport ’
mode is enabled in the standard
Porsche Active Suspension
Management (PASM) suspension.
The dampers become firmer,
enabling faster turn - in as well as
bet ter contact with the road.
In automatic mode of PDK,
the basic gearshif t pat tern is
switched to high-performance
mode. The gear change action is
virtually instantaneous, while the
shift points are timed for maxi -
mum acceleration. Lif t of f the
throt tle – even at high revs – and
the system automatically shif ts
down to apply engine braking. In
manual shif t mode, gear chang -
ing is faster and more dynamic.
Porsche Stabilit y Management
(PSM) is also adapted, with the
intervention threshold raised. As
a result, the car has a more natu -
ral response to lateral and longi -
tudinal forces. Cornering agilit y
is greatly enhanced, when both braking to turn in and applying
power on exit – particularly

in low-speed bends. For even
greater driving pleasure.
For maximum manoeuvrabilit y,
PSM can be partially disabled
while the car is still in ‘Sport ’
mode. PSM simply monitors the
forces acting on the car and
will only intervene in the most
critical scenarios, e.g. when ABS
assistance is required on both
front wheels.
In conjunction with PDK (standard
on 911 Turbo S models), the
Sport Chrono Package Turbo with
dynamic engine mount system
has t wo additional functions that can be activated via the SPORT
PLUS but ton, for a sport y drive
that borders on a motorsport
experience.
The first function is ‘Launch
Control’, which, for example
when per forming laps, helps you
achieve optimum acceleration
from a standing start, a racing
start in other words.
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 accel -
erate fully with the right foot.
The car recognises ‘Launch’ mode
from the accelerator kickdown action and adjusts the engine
speed to the optimum level,
which is around 5,000 rpm. At
the same time, boost pressure
is increased to approximately

0.5 bar, engine torque is
increased and the clutch is
applied lightly. ‘Launch Control’
now appears in the steering
wheel display. Now release the
brake as quickly as you can –
and feel the acceleration power
unleashed to the road.
