Three-spoke sports steering
wheel with gearshift switches
and multifunction option.
In conjunction with the optional
PDK, the three-spoke sports
steering wheel fit ted as standard
has t wo ergonomic switches
for changing gear.
One press
forwards with the thumb
and PDK
shifts up. One pull backwards with
the index finger and PDK shif ts
down. Either the right or lef t hand
can be used. Even if the gear selector is set to
automatic, you can still use the
switches to change gear manually
at any time. In this way, even in
automatic mode, you can achieve
a short burst of speed for an over
-
taking manoeuvre. The system
reverts to automatic mode if no
manual inputs are detected for
approximately eight seconds.
Using the PDK gear selector, you
can also change gear manually in
a separate one-touch manual shif t
gate. The control concept mirrors
the logic of the switches on the PDK steering wheel – press
forwards to shift up, pull back
-
wards to shift down.
A multifunction version of the
three-spoke sports steering wheel
is available on request. Steering
wheel heating is also optional.
When combined with the Sport
Chrono Package, there is an addi -
tional display* above the airbag
module. It tells you whether the
SPORT, SPORT PLUS and Launch
Control functions are activated.

Three-spoke sports steering
wheel with gearshift paddles.*
Available as an option is the three-
spoke sports steering wheel with
gearshif t paddles. The paddles
are made from a strong alloy and
are ergonomically located behind
the right and lef t steering wheel
spokes. Pull the right-hand paddle
and the PDK shif ts up. Pull the
left-hand paddle and the PDK
shif ts down.
Visually, the steering wheel is
distinguished by its distinctive
high - qualit y t win -spoke design and
silver-coloured spoke cover.
This steering wheel also has an
additional display when combined
with the Sport Chrono Package.
Located in the lef t and right-hand
steering wheel spokes, it tells you
whether SPORT, SPORT PLUS and
Launch Control are activated. Another feature reminiscent of the
world of motorsport is the top
centre marking on the steering
wheel rim.

Performance | Transmission
Fit ted as standard in the new
Panamera 4, the Panamera 4S
and the Panamera Turbo, Porsche
Traction Management (PTM) com -
prises an active all-wheel drive
with electronic and map-controlled
multi-plate clutch with automatic
brake differential (ABD) and anti -
slip regulation (ASR). The electronically controlled multi
-
plate clutch regulates the distri -
bution of drive force bet ween the
permanently driven rear axle and
the front axle.
Through continuous monitoring
of the driving conditions, the elec -
tronics are able to respond to a
variet y of situations. Sensors
check,
among other variables, the
rotation speeds of all four wheels,
the longitudinal and lateral accel -
eration of the vehicle, and the
steering angle.
If the rear wheels threaten to
spin under acceleration, a greater
proportion of drive force is distrib-
uted to the front by a more power -
ful engagement of the multiplate
clutch. In addition, ASR reduces
wheel slip. When cornering, the
front wheels only ever receive as
much drive force as is necessary
to maintain optimum lateral
stability. In this way, PTM, in conjunction
with Porsche Stabilit y Management
(PSM, p. 72), ensures that the
perfect distribution of drive is
achieved every time: whether on
long straights, through tight cor
-
ners, or on surfaces with dif ferent
friction coefficients. In this situa -
tion, traction is additionally enhanced by the automatic brake
differential (ABD).
Whenever the brake control

systems are required to intervene,
PTM decouples the front axle
completely so that PSM interven -
tions can take place at each
individual wheel.
You always like to have your feet firmly planted on the ground.
With all-wheel-drive, the principle is the same.

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.

Suspension.
The front axle has a wide-spaced
aluminium double wishbone
arrangement with an aluminium subframe. The wide spacing
bet ween the wishbones keeps the
forces in the wheel suspension
low for precision wheel guidance
and excellent handling. The rear axle is an aluminium
multi-link setup. This axle design
minimises the pitching of the body
under acceleration and braking.
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 and increase agilit y.
Steering and Servotronic.
Precise and direct: describes a
t ypical Porsche steering system
–
with variable steering ratio.
Around the straight ahead position,
such as during motorway driving,
the ratio is less direct with no loss
of agilit y or feedback from the
road. When the steering wheel is
turned further, the ratio becomes
more direct, allowing easier cor -
nering and parking.
Servotronic, a speed-sensitive
power-steering system, is available
as an option for all Panamera
models. At high speeds, the steer -
ing is firm and responds with
extreme precision while steering comfort remains as high as you
would expect. At low speeds,

Servotronic’s ratio adjusts for
easy manoeuvring and parking.
Wheels and Tyre Pressure
Monitoring (TPM).
The new Panamera and Panamera 4
models are fit ted as standard with
18-inch Panamera wheels, the
Panamera S and 4S with 18-inch
Panamera S wheels. All wheels
are light weight alloys featuring a
classic sport y design. Tyre sizes
245/50 ZR 18 and 275/45 ZR 18
are fit ted to the front and rear,
respectively. The Panamera Turbo is equipped
with 19 -inch Panamera Turbo alloy
wheels as standard. The t yres
are slightly wider to cope with the
increased power output of this
model: 255/45 ZR 19 at the front,
285/40 ZR 19 at the rear.
A selection of 18-inch to 20 -inch
wheels is available from our range
of options (p. 147).
19-inch all-season t yres are
offered as an alternative at no
extra cost for all Panamera
models with standard or optional
19-inch wheels. A low-rolling
resistance version of these t yres
is available as an option*. The

main components of the
Panamera Turbo front axle

ture of the t yre substructure –
have been optimised to minimise
roll resistance and thus improve
fuel economy, with no ef fect on
comfort or performance compared
with the regular 19 -inch all-season
t yres.
For increased comfort and safet y,
Tyre Pressure Monitoring (TPM)
sends warnings to the on -board
computer’s display screen in
the event of low t yre pressure as
well as in the event of a loss of
pressure. The system is available
as an option for the Panamera
and Panamera 4 and is standard
in all other models.

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.

Adaptive air suspension.
The Panamera Turbo is equipped
with adaptive air suspension and
PASM as standard. This combined
system enhances both driving
dynamics and comfort at the
same time. For all other Panamera
models, adaptive air suspension
is available as an option. It comprises a levelling system,

a manual lif t function, ride-height
adjustment capabilit y and the
abilit y to vary the spring rate.
The purpose of the levelling
system is to automatically keep
the vehicle level constant,
re
gardless of load distribution.
For manoeuvring, the manual
lif t function enables you to raise
the vehicle body by 20 mm to minimise the risk of grounding,
e.
g. when entering garages.*
When you select the ‘SPORT
PLUS’ chassis programme, the
height of the body automatically
drops to Low Level (–25 mm). At
the same time, a harder spring
rating is achieved through a
reduction in the amount of air
stored in the air suspension.
In simple terms, it ’s a sports
chassis at the push of a but ton.
High Level.
At 20 mm above Normal Level,
this is intended for driving over
ramps and into garage entrances.
The chassis automatically reverts
to Normal Level as soon as
the vehicle reaches a speed of
18 mph (30 km/ h).
Normal Level.
The usual height for the system
with a maximum ground clearance
of 144 mm above DIN unladen
weight.
Low Level.
This is 25 mm below Normal
Level with a maximum ground
clearance of 119 mm. In ‘SPORT
PLUS’ mode, the vehicle body
drops to Low Level and a harder
spring rate is set. This assures
optimum roadholding with a
sport y driving st yle.

* The vehicle must not be driven at High
Level on public roads as the maximum
permissible installation height of the
reflector units may then be exceeded.

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.
Even a Porsche has limits to its dynamic performance.
