SPORT button.
All Panamera models are
equipped with the SPORT but ton
as standard. This feature enables
the driver to vary the engine
characteristics and, in vehicles
with PASM, the suspension setup.
In vehicles with Porsche Doppel-
kupplung (PDK), the SPORT
but ton can be used to select a
sportier gearshif t strategy. For
more information, please refer
to page 74.
Auto start/stop function (only
in conjunction with Porsche
Doppelkupplung, PDK).
Silence: the t ypical stationary
noise. If, for example, you stop at
traf fic lights with your foot on
the brake pedal, the Auto start /
stop function will automatically
stop the engine. This fuel -saving
system restarts the engine as
soon as you release the brakes.
A key advantage is that there is
no need for you to change your
driving habits. You can simply
carry on as normal. All audio and
communication systems remain
switched on and the climate
control continues to maintain your
selected temperature, despite the
engine being switched of f. The
engine restarts if more power or
extra cooling output is required.
The Auto start /stop function
can be activated and deactivated
using a separate but ton. The
function may remain inactive under
particular circumstances, e.g.
very high outside temperatures,
on extreme uphill gradients, or if
bat tery charge is low.
The starter has been modified to
meet the increased requirements
demanded by this function and the bat tery is continuously moni
-
tored for the level of charge and
condition. The bat tery and starter
are consumable components and
are subject to an increased rate
of wear in the event of frequent
engine stopping.
Fuel economy is further improved
by electrical system recuperation,
whereby the bat tery is charged
predominantly under braking.
Under acceleration, on the other
hand, the alternator’s charging
current is reduced so that the
engine does not need to work as
hard to charge the bat tery.
Performance | Engines
With millisecond precision, DFI
injects fuel at up to 120 bar di rect -
l y
into the combustion chamber
by means of electromagnetically
actuated injection valves.
The spray and cone angles have
been optimised for torque, power
output, fuel consumption and
emissions by enabling a homoge -
neous distribution of the air/fuel
mixture, and, therefore, ef fective combustion. At up to 3,500 rpm,
the engine operates with dual
injection for faster heating of the
cataly tic converters af ter a cold
start and for greater torque in the
upper load range.
DFI improves the internal cooling
of the combustion chamber by
having the mixture prepared
direct
ly in the cylinder. This allows
for a higher compression ratio, which helps to deliver more out
-
put at the same time as enhanced
engine ef ficiency. Injection is
regulated by the electronic engine
management system and emis-
sions are monitored by the stereo
Lambda sensors, thus helping to
protect the environment.
A sense of relaxation is felt especially
after a period of intense pressure.
Direct fuel injection (DFI).

VarioCam Plus.
VarioCam Plus is a t wo -in - one
engine concept for adjusting the
intake camshaf ts and switching
the lif t of the intake valves.
The system first dif ferentiates
bet ween driver inputs that t ypif y
normal, everyday driving and
those inputs that demand maxi -
mum performance. The electronic
engine management system then
seamlessly adapts valve operation
to the prevailing conditions. This
results in instant acceleration and
extremely smooth running. In the middle and low load ranges,
low valve lifts with advanced

timing reduce fuel consumption
and exhaust emissions and im -
prove smooth running. The i n -
crease in fuel economy is particu -
larly pronounced in the lower
engine speed range. High torque
and maximum output are achieved
through high valve lifts and ad -
vanced timing.
How does this benefit you?
Extraordinary power with
relatively low fuel consumption.
Exhaust turbocharging.
The Panamera Turbo has t wo
turbochargers arranged in parallel.
Intake air is compressed and then
fed to the engine via t wo charge-
air coolers, one for each cylinder
bank. Cooling of the compressed
air has t wo positive outcomes:
high cylinder charge and low com -
ponent temperatures. Under full
load, the boost pressure depends
on the current engine speed and
a maximum pressure of 0.85 bar is
achieved at 2,500 rpm at sea
level.
With the optional Sport Chrono
Package Turbo, the boost pressure
produced at full throt tle in the
2,000 rpm to 5,000 rpm range is
temporarily increased by up to
10 % by the ‘overboost ’ function.
VarioCam Plus
Lightweight exhaust system.
The exhaust system is made from
selected longlife stainless steel.
The powerful primary and main
cataly tic converters heat up
rapidly for ef fective emissions
control. As a result, all Panamera
models are equipped to meet
the Euro 5 emission standard in
Europe.
The exhaust system of the
Panamera Turbo switches bet ween
t wo configurations automatically:
low noise at low engine speeds,
and increased throughput at high
revs under maximum engine load.
Sports exhaust system.
An optional sports exhaust system
is available for the Panamera S
models and Panamera Turbo.
Acti
vated by a separate but ton, it
produces an even more authentic
sportscar sound.

Porsche Doppelkupplung (PDK).
The 7-speed PDK – fit ted as
standard in the Panamera 4,
Panamera 4S and Panamera Turbo
and available as an option in the
Panamera and Panamera S –
has both a manual gearshif t and
an automatic mode and enables
smooth gear changes with no
interruption in the flow of power.
Porsche Doppelkupplung (PDK)
Gear lever
Six-speed manual gearbox.
For precision handling: the 6-speed
manual gearbox fit ted as standard
in the Panamera and Panamera S
is tuned for sport y performance
with optimum connection to
the individual gears and extremely
precise shif t throws. Thanks to the elevated centre
console, the gear lever is within
easy reach – ideal for sport y
shifting. The cable-operated gear
-
shif t unit has a precise feel and
the gear lever is insulated against
vibration. Together with the dual-
mass fly wheel, this minimises
noise and is key to providing a
high level of comfort.
An upshift indicator in the instru -
ment cluster helps to further
improve fuel economy. Porsche
Doppelkupplung (PDK) is available
as an option for both of these
models.
Gears 1 to 6 have a sports ratio
and top speed is reached in 6th
gear. The 7th gear has a long
ratio, which reduces fuel consump-
tion even further and keeps engine

revs comfortably low even at
high road speeds. PDK is essentially t wo gearboxes
in one and thus requires t wo
clutches. This double clutch pro
-
vides an alternating, non-positive
connection bet ween the t wo
half gearboxes and the engine by means of t wo separate input shaf ts
(input shaf t 1 is nested inside
the hollowed - out input shaf t 2).

Performance | Transmission
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
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.

All -wheel drive
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
three
main components of the
Panamera Turbo front axle

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

For increased comfort and safet y,
Tyre Pressure Monitoring (TPM)
sends warnings to the on -board

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.
