V8 twin-turbo engine.
The Panamera Turbo is powered
by a 4.8-litre V8 t win -turbo engine
with direct fuel injection (DFI),
VarioCam Plus and charge-air
cooling. It generates 368 kW
(500 hp) at 6,000 rpm and its
maximum torque of 700 Nm is
available bet ween 2,250 and
4,500 rpm. With a top speed of
188 mph (303 km/ h), it races
from 0 to 62 mph (100 km/ h) in
4.2 seconds. Using the Launch
Control function of the Sport
Chrono Package Turbo (p. 76),
the clock stops even sooner at
4.0 seconds.

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.

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.

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.

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.
