force is distributed to the front by a more
powerful 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 guarantee optimum
lateral stabilit y. In this way, PTM, in inter -
action with Porsche Stabilit y Management
(PSM, p. 27) ensures that the perfect
distribution of drive is achieved every
time: whether on long straights, through
tight corners, or on surfaces with differ -
ent friction coef ficients. In this situation,
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 inter -
ventions can take place at each individual
wheel.
SportDesign steering wheel.
In the Panamera GTS, the SportDesign
steering wheel is fit ted as standard and
features gearshift paddles and a top
centre marking on its smooth-finish
leather rim.
The paddles are made from a strong
alloy and are ergonomically located
behind the right and left steering wheel
spokes. Pull the right-hand paddle to
shift up and pull the left-hand paddle
to shift down. A display in the left- and
right-hand steering wheel spokes tells
you whether SPORT, SPORT PLUS and
‘Launch Control’ (p. 28) are activated.
As an option, it is possible to have the
SportDesign steering wheel rim finished
in black Alcantara.
Porsche T raction Management (PTM).
Fit ted as standard in the Panamera GTS,
Porsche Traction Management (PTM)
comprises an active all-wheel drive with
electronic and mapcontrolled multiplate
clutch with automatic brake differential
(ABD) and antislip regulation (ASR).
The electronically controlled multiplate
clutch regulates the fully variable distrib -
ution of drive force bet ween the perma -
nently driven rear axle and the front axle.
Through continuous monitoring of driving
conditions, the electronics 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 acceleration
of the vehicle, and the steering angle.
If the rear wheels threaten to spin under
acceleration, a greater proportion of drive

Porsche Stability Management (PSM).
PSM is an automatic control system
that stabilises the vehicle at the limits of
dynamic driving performance. Sensors
continuously monitor driving direction,
speed, yaw velocit y and lateral accelera -
tion. Using this information, PSM com -
putes the actual direction of motion. If
this direction deviates from the desired
course, PSM can, for example, initiate
braking interventions targeted at individual
wheels in order to stabilise the vehicle.
Under acceleration on wet or low-grip
road surfaces, PSM improves traction
using the ABD (automatic brake
differential) and ASR (antislip regulation)
functions.
For an even more involving driving
experience, 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.
PSM comes with t wo additional
functions: precharging of the brake
system, enabling maximum braking
power to be achieved much sooner;
and brake assist, for maximum
deceleration in a critical situation.
Porsche Dynamic Chassis Control
(PDCC) including Porsche Torque
Vectoring Plus (PTV Plus).
PDCC is available as an option for the
Panamera GTS. This is an active anti-roll
system that anticipates and significantly
reduces lateral body movement during
cornering manoeuvres. In addition, it
minimises the lateral instability of the vehicle on uneven ground. The effect 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 con -
junction with an electronically regulated
rear differential lock, it works by varying
the torque distribution to the rear
wheels. To be more precise, this means
that when the car is driven assertively
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 vehi -
cle’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 accelerating out
of corners, the electronically regulated
rear dif ferential lock ensures greater

driving stabilit y. It also serves to improve
traction at the rear wheels on road sur -
faces with varying levels of grip, in the
wet and on snow.
For the driver, this means remarkable
lateral vehicle stabilit y, optimum traction
as well as a high degree of agilit y at
every speed with precise steering and
stable load transfer characteristics. In
short, it offers pure driving pleasure.

speed of your vehicle by restricting throt -
tle or by gently applying the brakes until
your chosen distance from the vehicle in
front is maintained. If the vehicle ahead
slows further, adaptive cruise control
will decelerate your vehicle accordingly.
As soon as the road ahead clears, your
vehicle will accelerate back up to the
cruising speed originally set.
Lane Change Assist.
The optional Lane Change Assist uses
radar sensors to monitor the areas to the
rear of the vehicle and the blind spots
on either side. Above a speed of 18 mph
(30 km/ h), the system issues a visual
warning signal in the exterior mirrors
whenever a vehicle rapidly approaches
your vehicle from behind or enters one
of your blind spots. In this way, Lane
Change Assist improves comfort and
ParkAssist and reversing camera.
Park Assist is fit ted as standard. With
four sensors installed at the rear and six
sensors at the front, it audibly alerts
the driver to the presence of obstacles
detected behind or infront of the vehicle.
The audible alert is supplemented by a
visual warning in the central display
screen in the form of a graphical repre -
sentation of the vehicle’s surroundings.
The optional reversing camera facilitates
reverse parking with the aid of the cam -
era image and guidelines superimposed
on the PCM screen.
Adaptive cruise control.
Available as an option, this enhanced
version of cruise control regulates the
speed of your vehicle in line with the
speed of the vehicle in front. Imagine
you’ve selected a cruising speed but
have begun to gain on a slower-moving
vehicle. The system now reduces the
safety, particularly on motorways. How -
ever, it has no input into vehicle steering
and can be deactivated manually at any
time.
Porsche Entry & Drive.
Designed to minimise active key use,
Porsche Entry & Drive is available as
an option for the Panamera GTS and is recognisable by black inlays on the door
handles. As soon as you touch the door
handle, Porsche Entry & Drive checks

the access code stored in the key. Once
the key is validated, the door unlocks.
The engine can then be started and
switched off using the ignition switch.
To lock the vehicle, you simply press a
but ton on the outside of the door handle.
Porsche Entry & Drive then locks the
vehicle and activates the engine immobi -
liser and steering column lock.
