Porsche Traction Management (PTM).
Porsche Traction Management (PTM)
comprises an active all-wheel drive with
electronic and map - controlled multi - plate
clutch, with automatic brake differential
(ABD) and anti-slip regulation (ASR).
The electronically controlled multi - plate
clutch regulates the distribution of drive
force bet ween the permanently driven
rear axle and the front axle. Through
continuous monitoring of the 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,
longitudinal and lateral acceleration of
the vehicle, and the steering angle. If, for
example, the rear wheels spin under
acceleration, a greater proportion of
drive force is redirected to the front by a
more powerful engagement of the multi-
plate clutch. In addition, ASR reduces
wheel slip. In corners, the drive force
sent to the front wheels is regulated for
optimum lateral stability.

In this way, PTM, in conjunction with
the upgraded version of Porsche Stabilit y
Management (PSM, p. 67) ensures
optimum force delivery in every driving
situation and excellent acceleration
power: whether on long straights, through
tight corners, or on road surfaces with
varying grip.
Standard in the Panamera 4,
