Power flow in 1st gear
Power flow in 2nd gear
The flow of power from the
engine is transmit ted through one
half gearbox and one clutch at a
time, while the next gear is pre -
selected in the other half gearbox.
During a gear change, therefore,
a complete shif t no longer takes
place. Instead, one clutch simply
opens and the other closes at the
same time. Gear changes can
therefore take place within a few
hundredths of a second.
Clutch 1 controls the first half
gearbox, which contains the odd
gears (1, 3, 5 and 7). Clutch 2
controls the second, which con -
tains the even gears (2, 4, 6 and
R). The gear which is engaged
is displayed on the instrument
cluster.
PDK has distinct benefits. A high
level of driving comfort and
very rapid gearshifts, with no
interruption in the flow of power,
produces faster acceleration.
Driving feels even sportier and
more dynamic, and agilit y is
increased. Depending on the gear -
shif t programme (SPORT but ton
activated or deactivated), the gear
change is optimised for comfort
or for sport y driving. Its high level
of ef ficiency combined with the
long-ratio 7th gear helps to
achieve reduced fuel consumption
and emission figures even when
compared with a standard manual

gearbox.
In conjunction with either the
optional Sport Chrono Package
Plus (p. 74) for all Panamera
models with a naturally aspirated
engine or the optional Sport
Chrono Package Turbo for the
Panamera Turbo (p. 76), PDK is
enhanced by a Launch Control
function which offers a sportier
acceleration and gearshift
strategy in automatic mode and
extremely smooth gear changes
in manual mode.
PDK offers sportiness with
efficiency and comfort. A new
definition of driving in the
pre
mium class from Porsche.

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

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.

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

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.

SPORT button.
The SPORT but ton, which is fit ted
as standard, enables you to
select a setup that favours either
comfort or sport y performance.
At the push of a but ton, the elec -
tronic engine management system
switches the engine mapping
to of fer an even sharper response
and engine dynamics that are more direct. In vehicles with
Porsche Doppelkupplung (PDK),
upshif ts in automatic mode take
place at higher engine speeds
than in ‘Comfort ’ mode and

downshifts are swifter. In addition,
Porsche Active Suspension
Management (PASM) and Porsche
Dynamic Chassis Control (PDCC)
also switch to ‘
SPORT’ mode to
deliver harder damping and more
direct steering and, therefore,
bet ter road holding.
Sport Chrono Package Plus.
You expect sport y performance,
otherwise you wouldn’t be consid -
ering a Porsche. Indeed, you
expect a higher level of sport y
performance, otherwise you
would have no urge to keep read-
ing. Available as an option for
all Panamera models equipped
with the naturally aspirated engine is the Sport Chrono Package Plus
(only in conjunction with Porsche
Communication Management –
PCM). This package of fers even
sportier tuning of the chassis and
engine setup – the ultimate sports
experience.
Included in the package are a
digital and analogue stopwatch,
the SPORT PLUS but ton, and a
per formance display in the PCM
for displaying lap times.
When the SPORT PLUS but ton
on the centre console is selected,
the engine management system
adapts for performance driving
and the rev-limiter is adjusted to a
harder set ting.
The Porsche Active Suspension
Management (PASM) – standard in
the Panamera S, 4S and Turbo,
optional for the Panamera and
Panamera 4 – also switches to ‘
SPORT PLUS’ mode for harder d a m p
-
ing
and more direct steering, and,
therefore, bet ter road holding. The
optional adaptive air suspension
(standard in the Panamera Turbo)
drops the chassis to Low Level
and hardens the spring rate.
In ‘
SPORT PLUS’ mode, the trigger
threshold for PSM is raised for
increased longitudinal and lateral
dynamics. Agilit y is enhanced
when braking for corners with PSM
enabling greater manoeuvrabilit y
under braking and exit accel-
eration, especially at low speeds.
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.
A key component of the Sport
Chrono Package Plus is the stop -
watch mounted on the dashboard.
It displays recorded driving time
in hours, minutes and seconds.
Seconds, tenths and hundredths
of a second appear on a display
screen. Alternatively, the stop -
watch can be used as a conven -
tional clock. Porsche Communica -
tion Management (PCM, p. 108)
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 and
the remaining range until empt y.
It is also useful away from the
racetrack. Evaluate your daily
mileage or define benchmark
times – and rediscover your old
routes.

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.

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.

concerned, we are already among
those manufacturers achieving
the lowest CO2 em issio ns. T h is
has been achieved through the
new ef ficient engine technology
(e.g. by DFI and VarioCam Plus),
light weight construction, optimum
aerodynamics and low rolling
resistance. This high level of environmental
responsibilit y is clearly demon
-
strated by our approach to envi -
ronmental management at the
Porsche Development Centre in
Weissach. Here, all technological
developments are carried out
with environmental protection in
mind. The goal is pure perform -
ance – but not at the expense of
the environment. A goal achieved
by the Panamera.
Fuel economy and emission
control.
Vehicles manufactured by Porsche
demonstrate that even high-
performance sportscars can
achieve moderate fuel consump -
tion and
exhaust emission values
in their
respective categor y.
The balance is exemplary: the
Panamera, Panamera 4 and
Panamera Turbo comply with the
Euro 5 emission standard in
Europe and the LEV regulations in
the USA, the Panamera S and
Panamera 4S meet the require -
ments of EU 5 and ULEV.
This is achieved through the use
of fuel- ef ficient technologies such
as direct fuel injection (DFI, p. 51)
and VarioCam Plus (p. 52).
Efficient emission control is
achieved by a t wo -stage cascade-
t ype cataly tic converter, which
comprises t wo monoliths arranged
in series. These specially coated
substrates contain ultra-fine honey -
comb
channels in which pollutants
are converted as exhaust gas
passes through.
The stereo Lambda control circuitr y
controls and monitors each cylin -
der bank separately. For each
exhaust tract, oxygen sensors
regulate the composition of the
exhaust gas, while another Lambda
s
ensor on each cylinder bank
monitors pollutant conversion in
the respective cataly tic converter.**
Environmental protection.
In an era of intensif ying debate
about global climate change and
CO
2 emissions, every automotive manufacturer is asking what it has
to of fer in terms of environmental
protection. Our answer has long
been the same: maximum effi
-
ciency. Porsche has been reducing the
CO
2 emissions of its vehicles
by an average of around 1.7 %*
every year for the past 15 years.
As far as engine output is

* The stated reduction in fuel consumption
has been calculated from the NEDC (New
European Drive Cycle) fuel consumption
figures for the respective model years
of the vehicles and in relation to the
applicable European legislation.
** Not in markets with leaded fuel.

· 94 ·· 95 ·
In models with the V8 engine,
exhaust gas cleaning is supported
by an air injection system. A com-
pressor pumps extra air into the
exhaust tract during the cataly tic
converter warm-up phase for
faster heating and, therefore,
lower emissions.
Other measures for improving fuel
economy are the Auto start/stop
function (p. 50) and electrical
system recuperation, whereby the
vehicle bat tery is charged pre-
dominantly under braking. Under
acceleration, on the other hand,
the charging current of the regu -
lated alternator is reduced so that
the engine does not need to work
as hard to charge the bat tery.
Lightweight construction and
recycling.
A fundamental objective in the
development of any Porsche is
intelligent lightweight construction.
For both economical and ecologi -
cal reasons. This forms the basis
for low fuel consumption values in conjunction with outstanding
performance. It is economical
thanks to the high proportion of
aluminium cast alloys, plastics
and super-high-strength sheet
steel used. This is substantially
more stable and lighter than

conventional steel. The Panamera
models have a bodyshell with a
light weight-metal content of 23 %.
For example, the bonnet, doors,
front wings and rear lid are made
of aluminium, which saves on
weight and has a positive ef fect
on the environmental balance:
according to eco balance sheets,
the extra energy used and the
higher emissions incurred in the
manufacturing of aluminium
are more than compensated by
the savings on fuel af ter only a
relatively short distance.
It is also responsible because all
materials used are meticulously
selected. We use only innovative
and environmentally friendly com -
ponents. All light weight materials
are easily recyclable and each
material is labelled to facilitate its
separation for recycling. The reduction in the number of plastic
variants helps to ensure more
efficient recycling. Recycled plas
-
tics are used where they meet our
exacting technical requirements
In all, the Panamera is approxi -
mately 95 % recyclable.
In addition, Porsche uses only
environmentally friendly water-
based paints, thus reducing
the need for solvents both in pro -
duction and in the workshop.
The Panamera is also absolutely
free of asbestos, CFCs and
components manufactured using
CFCs because, here at Porsche,
environmental protection does
not begin at the end of a vehicle’s
life. It starts at the planning and
development stage.
