stopping 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 deceleration is
immediately available.
PSM therefore offers a high level
of driving stability and safety
combined with extraordinary
agility. In line with the Porsche
philosophy.
precharging of the brake system,
and brake assist.
If you suddenly release the accel-
erator pedal, PSM detects the
release of the throttle 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
For an even more dynamic

however, remain active at all
times.
For an even higher level of active
safety, the enhanced PSM
includes two additional functions:
automatic brake differential
(ABD), anti-slip regulation (ASR)
and engine drag torque control
(MSR).

direction of travel at any given
moment. If the car begins to over-
steer or understeer, PSM applies
selective braking on individual
wheels to restore stability.
Under acceleration on wet or low-
grip road surfaces, PSM improves
traction – and agility – using the
As standard, all of the new
Panamera models are equipped
with enhanced Porsche Stability
Management (PSM), which main-
tains stability even at the limits
of dynamic driving performance.
Sensors continuously monitor the
