Through the purposeful use of
light weight technologies, we have
managed to save weight in the
chassis and increase ef ficiency.
The next challenge was the
question of how to reconcile the
characteristics of a sportscar
with the requirements for comfort
demanded of a saloon. The
answer: modern axle concepts.
Two apparently more mutually
exclusive qualities are high
performance and excellent driving
safet y, which we resolved with
precise traction control systems
and powerful t yres and brakes.

Standard in the Panamera S, 4S
and Turbo and optional for the
Panamera and Panamera 4, PASM
is an electronic damping control
system which of fers continuous
adjustment of the damping forces
according to the road conditions
and driving st yle.
Designed to operate in accord-
ance with the skyhook principle, the suspension acts to keep the
body stable. This reduces body
movement and thus increases
comfort in each of the four seats.
Using a separate but ton on the
centre console, the driver can
select bet ween three modes:
‘Comfort ’, ‘SPORT’ or ‘SPORT
PLUS’. Sensors record the body
movements that accompany powerful acceleration, braking
and rapid cornering or uneven
road surfaces.
Signals such as lateral accel-
eration, steering angle, brake
pressure and engine torque are
also analysed. The PASM control
unit evaluates the driving condi
-
tions and modifies the damping
force on each of the wheels
in accordance with the selected
mode.
For your safet y, PASM contin -
uously monitors the driving condi -
tions. If you are driving in ‘Comfort ’
mode and suddenly adopt a
sportier and more dynamic driving
st yle, the system automatically
switches to a harder rating within
the ‘Comfort ’ setup range to
increase driving stabilit y and
safet y. If, in ‘SPORT’ or ‘SPORT PLUS’
mode, the qualit y of the road
sur face drops below a certain
threshold, PASM immediately
switches to
a softer rating within
the setup range to optimise
traction and grip. As soon as
the road surface improves, the
system reverts to the original
harder rating.
This may sound rather compli
-
cated, but for you it involves
nothing more than the press of a
but ton. And you can feel the
result: increased driving stabilit y,
more comfort and improved
performance.

A Porsche holds the road well, its
handling is sport y and precise –
but you’ve known this for a long
time.
What you might not know is
that, with the optional Porsche
Dynamic Chassis Control (PDCC)
with Porsche Torque Vectoring
Plus (PT V Plus), road holding can
be even further improved in all the Panamera models for even more
dynamic per formance and
increased comfort.
PDCC is an active anti-roll system
that anticipates and significantly
reduces lateral body movement
during cornering manoeuvres. In
addition, it minimises the lateral
instabilit y of the vehicle on uneven
ground. The ef fect is achieved with the aid of active anti-roll bars
on the front and rear axles which
respond to the current steering
angle and lateral acceleration

by producing a stabilising force
that precisely negates the roll
of the body.
PT V Plus combined with PDCC is
a system that actively enhances
vehicle dynamics and stabilit y. Operating in conjunction with an
electronically regulated rear dif
-
ferential lock, it works by varying
the torque distribution to the rear
wheels. As a function of steering
angle and steering speed,
accel -
erator pedal position, yaw rate and

vehicle speed, PT V Plus is able
to improve steering response and
steering precision by specific
braking of the right or left rear
wheel.
To be more precise, this means
that when the car is driven asser -
tively into a corner, moderate
brake pressure is applied to the inside rear wheel. Consequently,
a greater amount of drive force is
distributed to the outside rear
wheel, inducing an additional
rotational pulse (yaw movement)
around the vehicle’s vertical axis.
This results in a direct and sport y
steering action as the car enters
the corner.
At low and medium vehicle speeds,
PT V Plus significantly increases
agilit y and steering precision.
At high speeds and when acceler -
ating out of corners, the elec -
tron
ically regulated rear differential
lock ensures greater driving
stabilit y. It also serves to improve
traction at the rear wheels on
road surfaces with varying levels
of grip as well as on snow and ice.
For the driver, this means remark -
able stabilit y and easier handling,
optimum traction, and greater
agilit y at every speed with precise
steering and stable load transfer
characteristics. The result is
a high level of driving pleasure.

As standard, all Panamera models
are equipped with enhanced
Porsche Stabilit y Management
(PSM), which maintains stabilit y
even at the limits of dynamic
driving per formance. Sensors
continuously monitor the direction,
speed, yaw velocit y and lateral
acceleration of the car. Using
this information, PSM is able to calculate the actual direction of
travel at any given moment. If

the car be gins to oversteer or
understeer, PSM applies selective
braking
on individual wheels to
restore
stabilit y.
Under acceleration on wet or low-
grip road surfaces, PSM improves
traction – and agilit y – using the
automatic brake dif ferential (ABD), antislip regulation (ASR) and
engine drag torque control (MSR).
When ‘SPORT PLUS’ mode is
selected
on the optional Sport
Chrono Package Plus (p. 74)
or Sport
Chrono Package Turbo
(p. 76), the PSM intervention
threshold is raised to allow a
sportier driving st yle.
For an even more dynamic expe-
rience, you always have the
option to deactivate PSM. It is
automatically reactivated, for your
safet y, only if you brake harder
and either of the front wheels (in
SPORT PLUS mode, both of the front
wheels) requires ABS assistance.
ABS and ABD, however, remain
active at all times.
For an even higher level of active
safet y, the enhanced PSM includes
t wo additional functions: pre -
charging of the brake system, and
brake assist. If you suddenly release the accel
-
erator pedal, PSM detects the
release of the throt tle and auto -
matically readies the braking
system. This precharging of the
braking system builds up a small
amount of pressure so that the
brake pads are already in light
contact with the brake discs. If
you actually need to apply the
brakes, maximum braking power
is therefore achieved much
sooner, which reduces the stop -
ping distance even further. Brake
assist, on the other hand, is
able to interpret a panic braking situation from a rapid increase in
brake pressure and acts to ensure
that the amount of brake pressure
required for maximum decelera
-
tion is immediately available.
PSM therefore of fers a high level
of driving stabilit y and safet y com -
bined with extraordinary agil
it y.
In line with the Porsche philosophy.

For the Panamera 4 and 4S, and
for the Panamera and Panamera S
when fit ted in combination with
Porsche Doppelkupplung
(PDK),
the optional Sport Chrono Package
Plus contains even more functions.
The shift times in ‘SPORT PLUS’
mode are shorter, the gear
changes sportier. In automatic
mode and at low rates of decel -
eration – even with high engine
speeds – the system initiates a
swif ter brake-induced downshif t.
In manual mode, gear changes
are faster, more dynamic and
more direct.
A special feature of this package
that further enhances sport y
performance is Launch Control,
which is designed to produce opti -
mum acceleration from a standing
start. This function is operated via
the SPORT PLUS but ton with the
‘D’ or ‘M’ drive position selected.
With the left foot depressing
the brake pedal, the driver fully
depresses the accelerator for
maximum throt tle. The engine is
rev ved to an optimum speed of
around 5,500 rpm and the clutch
is already held in slight contact.
The message ‘Launch Control active’ appears in the display on
the steering wheel for PDK* or
optional three-spoke sports steer
-
ing wheel with gearshif t paddles*.
Now, the driver simply releases
the brake pedal, and prepares for
maximum acceleration.
Sport Chrono Package Turbo.
For the Panamera Turbo, increased
power output is a mat ter of prin -
ciple. The same applies to the
optional Sport Chrono Package
Turbo. Typifying the Turbo philos -
ophy, it not only combines all the
functions of Sport Chrono Package
Plus, it adds one more: Overboost.
Imagine you are accelerating
at full throt tle with the SPORT or
SPORT PLUS but ton selected.
Boost pressure is temporarily
increased by 10 %, which considerably increases the maxi -
mum torque that the engine is
able to produce. Instead of the
normal 700 Nm, the overboost
function
generates a torque of up
to 770 Nm for a limited period
and
a feeling of satisfaction that
lasts even longer.

The Porsche Dynamic Light Sys-
tem (PDLS) is standard on the
Panamera Turbo and available as
an option for all other Panamera
models. Its dynamic cornering
light function swivels the head -
lights towards the inside of a bend
based on steering angle and road
speed and the static cornering
lights activate the auxiliary head -
lights in order to illuminate more
of the road on tight bends and
turns. Put simply, when you enter
a bend, the road ahead is illumi -
nated immediately so you can see
any obstacles much sooner.
The system also features speed-
dependent headlight range con -
trol. With adaptive light systems,
it is possible for the maximum
range of the dipped beams to be
increased as a function of the
speed of the vehicle. PDLS takes
care of this automatically. Stage
1 is the basic position for driving in cit y traffic,
for example. Stage
2 is for designed for driving at
faster
speeds, such as on the
motorway. Here, the range of the
dipped beams is adjusted by
adapting the shape of the light
cone, extending it further forward
to improve visibilit y without
dazzling oncoming traffic.
Another feature of the PDLS,
the adverse weather function, is
activated when you switch on
the rear fog
light. It reduces the
effect of reflection phenomena
in poor visibility conditions, e.g.
fog,
heav y rain or snow fall. The
dipped beams are fanned out
and the light cone is lowered to
reduce
the risk of the driver
being
dazzled.
Vehicles with the driver memory
package or 14-way power seats
with memory package (standard
in the Panamera Turbo) feature LED courtesy lights in the exterior
mirrors to illuminate the area
around the doors.
In the event of sudden braking,
the adaptive LED brake lights of
the Panamera model range pulsate
to alert following traffic more
quickly to a critical situation.
Cut ting edge LED technology is
also used for the taillights, the
additional brake light in the rear
lid, the rear direction indicators
and the rear fog light. LEDs
provide bet ter illumination and
respond more quickly to driver
input. Not only do they increase
active safet y in this way, they are
energy ef ficient, eco -friendly
and have a longer service life than
conventional bulbs. Furthermore,
their design is unmistakably

Porsche, day or night.

Porsche brakes are renowned
for their stopping power, set ting
the standards for deceleration
and stabilit y. They are designed to
cope with extreme forces such
as those experienced during hard
braking.
The Panamera, Panamera 4,
Panamera S and Panamera 4S all
have a braking system equipped
with six-piston aluminium mono -
bloc fixed brake calipers at the front and four-piston aluminium
monobloc fixed calipers at
the rear. The brake calipers on
the Panamera and Panamera 4
are finished in black; on the
Panamera S and Panamera 4S,
they are silver-coloured.

The brake disc diameters are
360 mm and 330 mm at the
front and rear respectively.
Owing to its greater engine
power, the Panamera Turbo’s braking system features red-
painted six-piston aluminium mono
-
bloc
fixed brake calipers at the
front and a four-piston unit at the
rear, and brake discs with a
diameter of 390 mm at the front
and 350 mm at the rear for
outstanding braking performance
and a short braking distance.
The brake calipers have an
enclosed monobloc construction.
This makes them tough but light
and enables a rapid response and
release of the brake. The pedal
travel is short and easy to control.
All models have grooved brake
discs ensuring optimum braking
even under extreme conditions.
The discs are internally vented for
rapid heat dispersal.
The Panamera models are also
equipped with an anti-lock braking system (ABS), designed to keep
deceleration constant. A specially
designed air duct cools the brakes
effectively and, for added safet y,
a brake pad wear indicator for
each wheel informs you when the
brake pads need to be replaced.
The electric parking brake, which
you can activate and deactivate
manually, releases automatically
as you pull away. With the hill-hold function, you can pull away with
-
out ever rolling back. The system
automatically detects when the
vehicle has come to a halt on an
uphill gradient. PSM then main -
tains the brake pressure at all four
wheels for a brief period to pre -
vent the vehicle from moving in
the opposite direction.

On request, we can equip any
Panamera model in the range with
a braking system that has already
had to cope with the harshest
requirements of the racetrack: the
Porsche Ceramic Composite Brake (PCCB). For the Panamera
and Panamera S models, it is
available only in conjunction with
19 -inch wheels or larger and for
the Panamera Turbo, it is com
-
patible only with 20 -inch wheels.
On the Panamera and
Panamera S models, the cross-
drilled ceramic brake discs have
a diameter of 390 mm at the
front and 350 mm at the rear. To
cope with more powerful brak -
ing on the Panamera Turbo,
these discs are 410 mm at the
front and 350 mm at the rear.
PCCB is characterised by its low
thermal expansion, which pre -
vents deformation under heav y
braking. Furthermore, the
ceramic brake discs are totally
resistant to corrosion and offer
more favourable noise- damping
properties. The use of six-piston aluminium
monobloc brake calipers on the
front axle and four-piston units at
the rear – all finished in yellow
– ensures extremely high brake
forces which, crucially, are excep
-
tionally consistent. The pedal
response is fast and precise with
only moderate input required.
All the necessary ingredients are
there for a short braking distance,
even in the toughest conditions.
Moreover, safet y under braking at
high speeds is increased thanks
to the excellent fade resistance of
PCCB.
The key advantage of PCCB is
the extremely low weight of the
ceramic brake discs, which are
approximately 50 % lighter than
standard discs of similar design
and size. As well as enhancing
performance and fuel economy, this represents a major reduction
in unsprung and rotating masses.
The consequence of this is bet ter
road holding and increased com
-
fort, particularly on uneven roads,
as well as greater agilit y and
improved handling. Please note that circuit racing,
track day use and other forms of
performance driving can signifi
-
cantly reduce the service life of
even the most durable brake pads
and discs.
As with conventional high-
performance braking systems,
we recommend that all brake
components be professionally
inspected and replaced where
necessary after every track
event.
