Just a second, you may be think-
ing, sports saloons already exist.
Exactly what is so new about all
this? What is required when sport y
luxury alone is not enough? Well,
how about a Porsche with four
doors and four seats in the pre -
mium class – a Gran Turismo with
sportscar technology.
The new 3.6 -litre V6 engine is
naturally aspirated and produces
300 hp. The 4.8-litre V8 engines,
either naturally aspirated or t win-
turbocharged, generate 400 hp
and 500 hp respectively. All
engines feature VarioCam Plus
(p. 52) and direct fuel injection
(DFI, p. 51) for efficient com -
bustion, a distinct rise in power
and torque, and comparatively
low fuel consumption for this
class of engine.
A breath of fresh air in the premium class:
sportscar technology.
Engineering.
Fuel economy is also boosted
by an Auto start /stop function,
only in conjunction with Porsche
Doppelkupplung (PDK). If, for
example, you stop at traf fic lights
with your foot on the brake pedal,
the system will automatically
stop the engine. The engine
restarts as soon as you release
the brakes or move the steering
wheel, for example.
An optional sports exhaust system
is available for the Panamera S
models and the Panamera Turbo.
Activated by a separate but ton, it
produces an even more authentic
sportscar sound.
As you would expect from a
sportscar, power is transmit ted
quickly and precisely. In the new
Panamera and the Panamera S,
power is delivered to the rear axle by a 6-speed manual transmis
-
sion. In the new Panamera 4, the
Panamera 4S and the Panamera
Turbo, all of which feature the
7-speed Porsche Doppelkupplung
(PDK, p. 55) as standard, drive
force is distributed bet ween the
front and rear axles by the active
all-wheel drive of Porsche Traction
Management (PTM, p. 60) with an
electronic and map-controlled mul-
ti
plate clutch for optimum traction
and driving stability.
PDK is based on a development
that helped Porsche racing cars in
the 1980s to cause a sensation
on racetracks around the world.
Gear changes take place within
hundredths of a second and
with no interruption in the flow of
power – for sport y acceleration
with a high level of comfort and a
low rate of fuel consumption.
Also new to the premium class
are the optional Sport Chrono
Packages (p. 74). These further
enhance the driving dynamics of
the Panamera models at the push
of a but ton. Two special functions are available in conjunction with
PDK: Launch Control for optimum
acceleration from a standing
start and, in the Panamera Turbo,
the ‘overboost ’ function. This
feature increases boost pressure

Porsche Active Suspension Man-
agement (PASM, p. 66) comes
as standard on the Panamera S,
4S and Turbo, and is available as
an option for the new Panamera
and Panamera 4 models. This
system actively and continuously
regulates the damping force for
each wheel according to the road
conditions and driving st yle. Any
one of three suspension set tings
can be selected. The Panamera
Turbo additionally features adap -
tive air suspension (p. 68) as
standard, for increased comfort or a sportier ride – in simple
terms, it ’s a sports chassis at the
push of a but ton.
Available as an option for all
Panamera models is Porsche
Dynamic Chassis Control (PDCC)
with Porsche Torque Vectoring
Plus (PT V Plus). This active anti-
roll system reduces the lateral
tilt of the vehicle when cornering
and thereby improves agilit y and
safet y. Combined with PDCC,
PT V Plus of fers increased traction
and driving dynamics (p. 70). The Porsche Ceramic Composite
Brake (PCCB, p. 86) can be fit ted
on request. On the Panamera,
Panamera 4, Panamera S and
Panamera 4S models, the
grooved ceramic brake discs have
a diameter of 390 mm at the

front and 350 mm at the rear
(only in conjunction with 19-inch
wheels or larger). For more
powerful brak ing, the discs on the
Panamera Turbo are 410 mm at
the front and 350 mm at the rear
(only compatible with 20 -inch
wheels). This advanced braking
system of fers high -performance
braking at all times.
All Panamera models are con -
structed using light weight hybrid
materials. The axles, bonnet,
front wings, doors and rear lid, for
example, are made from alumin -
ium and the window frames and
cylinder head cover are made from
magnesium, all of which reduces
weight and therefore fuel con -
sumption.
A steering system with variable
steering ratio is fit ted as standard.
Servotronic (p. 64), a speed-sen -
si
tive power-steering system, is
available as an option.

On the new Panamera 4, drive
force is transmit ted to the road
by the active all-wheel drive of
Porsche Traction Management
(PTM, p. 60) and by the 7-speed
Porsche Doppelkupplung (PDK)
with Auto start /stop function, both
of which are fit ted as standard.
The steel spring suspension is
standard on both models, of fering
a high level of comfort despite
its sport y setup. Porsche Active
Suspension Management (PASM,
p. 66) or adaptive air suspension
with PASM are available on
request.
Also standard is Porsche Stabilit y
Management (PSM, p. 72), which
maintains stabilit y even at the
limits of dynamic driving perform -
ance, delivering bet ter traction
and increased safet y.
And yet the gross weight of these
models is as low as 1,730 kg. Driv-
ing pleasure is simply inevitable.
The figures speak for themselves:
the new Panamera accelerates
from 0 to 62 mph (100 km/ h) in
6.8 seconds, with a top speed
of 162 mph (261 km/ h). With the
optional Porsche Doppelkupplung
(PDK), these figures are an even
more impressive 6.3 seconds
and 161 mph (259 km/ h). The
Panamera 4 completes the 0 to
62 mph (100 km/ h) sprint in
just 6.1 seconds and has a top
speed of 159 mph (257 km/ h). Both models are equipped with

Bi-Xenon headlights as standard.
The interior offers plent y of
comfort and lots of space. The
t wo individual seats in the rear
compartment fold separately
or jointly, increasing luggage
capacit y to 1,263 litres. Auto -
matic climate control is standard.
Three interior colours are avail -
able for the partial leather interior.
The seat surfaces, inner backrest
sur faces and side bolsters,
door handles, door armrests and
armrest section of the centre
console are finished in embossed
leather, while the gear lever or

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.

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.

· 70 ·· 71 ·
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.
