Porsche Stability Management (PSM).
Enhanced Porsche Stability Management
(PSM) is fit ted as standard. This system
automatically maintains stability even
at the limits of dynamic driving perfor -
mance. Sensors continuously monitor
the 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 begins to oversteer or
understeer, PSM applies selective braking
on individual wheels in order to restore
stability. Under acceleration on wet or low-grip
road surfaces, PSM improves traction –
as well as agilit y and safet y – using the
automatic brake differential (ABD) and
anti-slip regulation (ASR). Integrated ABS
is designed to minimise braking distances.
If you prefer an ever sportier drive, PSM
can be switched off. For your safet y,

however, PSM remains set to intervene if
the vehicle is braked and ABS assistance
is required. ABS and ABD remain switched on at all times. Also included with PSM
are engine drag torque control (EDC),
precharging of the brake system and
brake assist. If you suddenly release the
accelerator pedal, PSM automatically
prepares for your next action: the braking
system is precharged so that the brake
pads are already in light contact with the
brake discs. Maximum braking power is therefore achieved much sooner. Brake
assist detects a panic braking situation
and generates the brake pressure
required for maximum deceleration.

Porsche Torque Vectoring (PTV).
This optional system for increasing
dynamic performance and stability varies
the distribution of torque to the rear
wheels and includes a mechanically lock -
ing rear differential. When the car is driven assertively into

a corner, moderate brake pressure is
applied to the inside rear wheel. Conse -
quently, 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
significantly increases agilit y and steering
precision. At high speeds and when

accelerating out of corners, the rear differ -
ential lock ensures greater driving stabilit y on a range of surface conditions, includ
-
ing the wet and snow.
The results are remarkable stabilit y, easier
handling and outstanding traction as
well as
greater agilit y at every speed with

characteristics. What else? As ever, lots
of
excitement at every t wist and turn.
