2015 PORSCHE 911 CARRERA 4S differential

Porsche Torque Vectoring (PTV) and
Porsche Torque Vectoring Plus (PTV Plus).
PTV (with manual transmission) or PTV Plus
(with PDK) is available as standard in
the S models and as an option for the
911 Carrera 4 models and the 911 Targa 4.
Both systems actively enhance vehicle
dynamics and stability. Operating in conjunction with a rear differential lock,
they work by intelligently braking the
rear wheels as the situation demands.

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
vehicle’s vertical axis. This results in
a direct and sport y steering action
from the turn-in point.
With PTV, the rear differential lock is
regulated mechanically, while PTV Plus is
equipped with electronic control offering
fully variable torque distribution. In
interaction with Porsche Stability
Management (PSM), the system improves

Chassis 57
Porsche Stability Management (PSM).
All 911 models are equipped with
enhanced Porsche Stability Management
(PSM) as standard. PSM maintains
stabilit y even at the limits of dynamic
driving performance. 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 and initiates strategic braking of
individual wheels to prevent you from
deviating from your intended line.
Under acceleration on inconsistent
surfaces, PSM improves traction using
the automatic brake differential (ABD) and anti-slip regulation (ASR) functions.
The result is a high level of driving
stability and safety – and extraordinary
agilit y at the same time.
