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.

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.

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.
Porsche Traction Management (PTM).

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.

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.

Cruise control.
Cruise control is fit ted as stand -
ard for added driver comfort on
long stretches of road. Cruise
control operates in the 30 to
240 km/ h (20 –150 mph) speed
range and is selected using a
but ton on the steering column
control stalk.
Adaptive cruise control.
Available as an option, this en -
hanced version of cruise control
regulates the speed of your vehicle in line with the speed of
the vehicle in front. How does it
work? A radar sensor inside the
front centre air intake scans the
road ahead up to a distance of
200 m.
If you’ve selected a cruis
-
ing
speed but have begun to gain
on
the vehicle in front because
it is driving more slowly, this is
detected by the radar sensor.
The system now reduces the
speed of your vehicle at a maxi -
mum rate of 3.5 m/s² by restrict -
ing the throt tle or gently applying
the brakes. This continues until
the distance that you have preset
is maintained. Your vehicle will now
follow the one in front at a re -
duced speed. If the other vehicle
decelerates further, adaptive
cruise control will continue to
reduce your cruising speed –
even down to a halt. For increased
safet y, the system also readies
the brakes whenever a decreasing
distance to the vehicle in front is
detected. Adaptive cruise control
and PSM interact to precharge
the braking system. If heavier
braking is required, the driver will
have to intervene manually.
As soon as the road ahead clears,
your vehicle will accelerate back
up to the cruising speed originally
set. To pull away af ter an auto -
matic stop, simply press the con -
trol lever or depress the accelera -
tor pedal.
Slide/tilt sunroof.
The slide/tilt sunroof is available
as an option for all Panamera
models. It is made from tinted
toughened safet y glass and fea -
tures a manually adjustable sliding
sunscreen and remote closing
function.
