The love of the road
inspires some remarkably intense relationships.
Transmission.
Porsche Doppelkupplung (PDK).
7-speed PDK, fit ted as standard in the
Macan models and featuring both a
manual and an automatic mode, offers
extremely fast gear changes with no
interruption in the flow of power – as well
as excellent driving dynamics and a high
degree of efficiency.
The principle of PDK is that, whenever a
particular gear is engaged, the next gear
is already preselected. As a result, gear
changes take place within milliseconds.
Automatic mode is optimised for fuel
economy. This means that PDK is able to
offer not only a sport y, agile driving feel,
but also increased efficiency. Would you rather change gear manually?
You can do this using the t wo gearshift
paddles on the multifunction sports
steering wheel, fit ted as standard, or
using the PDK gear selector.
In conjunction with the optional Sport
Chrono Package, the shift times of PDK
become even shorter, the gear changes
even sportier. Additional gearshift
strategies are also available – for
uncompromising driving pleasure.
Porsche Traction Management (PTM).
The tremendous dynamic performance
of the Macan is thanks in part to the
Porsche Traction Management (PTM)
active all-wheel drive system. It comprises an electronic and map-controlled
multi-plate clutch, the automatic brake
differential (ABD) and anti-slip regulation
(ASR). The electronically controlled multi-
plate clutch regulates the distribution of
drive force bet ween the rear axle and
the front axle. Driving conditions are
constantly monitored to enable a precise
and lightning-quick response to a variet y
of situations.
Sensors continuously check, among
other variables, the rotation speeds of all
four wheels, the longitudinal and lateral
acceleration of the vehicle, and the
steering angle. If, for example, the rear
wheels threaten to spin under
acceleration, a greater proportion of drive force is distributed 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 short, PTM transfers the incredible
sportiness of the Macan to the road.
Behind the wheel, you can feel what it ’s
like to be driving a genuine sports car:
traction, driving safety, outstanding
steering behaviour, superior handling
and, of course, the excellent dynamics
t ypical of any Porsche.
