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.

Porsche brakes are renowned
for their stopping power, set ting
the standards for deceleration
and stabilit y. They are designed to
cope with extreme forces such
as those experienced during hard
braking.
The Panamera, Panamera 4,
Panamera S and Panamera 4S all
have a braking system equipped
with six-piston aluminium mono -
bloc fixed brake calipers at the front and four-piston aluminium
monobloc fixed calipers at
the rear. The brake calipers on
the Panamera and Panamera 4
are finished in black; on the
Panamera S and Panamera 4S,
they are silver-coloured.

The brake disc diameters are
360 mm and 330 mm at the
front and rear respectively.
Owing to its greater engine
power, the Panamera Turbo’s braking system features red-
painted six-piston aluminium mono
-
bloc
fixed brake calipers at the
front and a four-piston unit at the
rear, and brake discs with a
diameter of 390 mm at the front
and 350 mm at the rear for
outstanding braking performance
and a short braking distance.
The brake calipers have an
enclosed monobloc construction.
This makes them tough but light
and enables a rapid response and
release of the brake. The pedal
travel is short and easy to control.
All models have grooved brake
discs ensuring optimum braking
even under extreme conditions.
The discs are internally vented for
rapid heat dispersal.
The Panamera models are also
equipped with an anti-lock braking system (ABS), designed to keep
deceleration constant. A specially
designed air duct cools the brakes
effectively and, for added safet y,
a brake pad wear indicator for
each wheel informs you when the
brake pads need to be replaced.
The electric parking brake, which
you can activate and deactivate
manually, releases automatically
as you pull away. With the hill-hold function, you can pull away with
-
out ever rolling back. The system
automatically detects when the
vehicle has come to a halt on an
uphill gradient. PSM then main -
tains the brake pressure at all four
wheels for a brief period to pre -
vent the vehicle from moving in
the opposite direction.

On request, we can equip any
Panamera model in the range with
a braking system that has already
had to cope with the harshest
requirements of the racetrack: the
Porsche Ceramic Composite Brake (PCCB). For the Panamera
and Panamera S models, it is
available only in conjunction with
19 -inch wheels or larger and for
the Panamera Turbo, it is com
-
patible only with 20 -inch wheels.
On the Panamera and
Panamera S models, the cross-
drilled ceramic brake discs have
a diameter of 390 mm at the
front and 350 mm at the rear. To
cope with more powerful brak -
ing on the Panamera Turbo,
these discs are 410 mm at the
front and 350 mm at the rear.
PCCB is characterised by its low
thermal expansion, which pre -
vents deformation under heav y
braking. Furthermore, the
ceramic brake discs are totally
resistant to corrosion and offer
more favourable noise- damping
properties. The use of six-piston aluminium
monobloc brake calipers on the
front axle and four-piston units at
the rear – all finished in yellow
– ensures extremely high brake
forces which, crucially, are excep
-
tionally consistent. The pedal
response is fast and precise with
only moderate input required.
All the necessary ingredients are
there for a short braking distance,
even in the toughest conditions.
Moreover, safet y under braking at
high speeds is increased thanks
to the excellent fade resistance of
PCCB.
The key advantage of PCCB is
the extremely low weight of the
ceramic brake discs, which are
approximately 50 % lighter than
standard discs of similar design
and size. As well as enhancing
performance and fuel economy, this represents a major reduction
in unsprung and rotating masses.
The consequence of this is bet ter
road holding and increased com
-
fort, particularly on uneven roads,
as well as greater agilit y and
improved handling. Please note that circuit racing,
track day use and other forms of
performance driving can signifi
-
cantly reduce the service life of
even the most durable brake pads
and discs.
As with conventional high-
performance braking systems,
we recommend that all brake
components be professionally
inspected and replaced where
necessary after every track
event.
