Porsche Traction Management
(P TM).
Genuine high per formance calls
for more than just a power ful
engine. It also requires an ef fec-
tive means of delivering that
power to the road. One solution
to this is all -wheel drive. An
even bet ter one is the further-
enhanced Porsche Traction
Management (PTM), consisting
of active all -wheel drive with
electronically controlled multi -
plate clutch and including an
automatic brake differential (ABD)
and anti -slip regulation (ASR).
PTM improves vehicle dynamics
even further whilst ensuring that
none of the customar y traction
and driving safet y is lost. The
result is an even more enjoyable
sport y ride combined with
exceptional stability.
Torque is distributed actively
– and exceptionally quickly –
via an electronically controlled
multi-plate clutch. The advantage is that, through
continuous monitoring of the
driving conditions, a more imme -
diate response to changing
scenarios can be achieved. The
status is monitored with the aid
of on-board sensors. These are
used to measure a range of
values, including the rotational
speed of all four wheels, the
lateral and longitudinal accelera -
tion of the car, and the current
steering angle. The sensor data
is analysed in ‘real time’, enabling
immediate adjustments in front-
end drive torque as and when
required. If, for example, the rear
wheels lose traction under
acceleration, a greater proportion
of drive torque is automatically
transmit ted to the front axle. At
the same time, ASR prevents the
rear wheels from spinning by
adapting the engine power. When
cornering, the system controls
drive to the front wheels in order
to maintain optimum lateral grip.
On variable-grip surfaces, traction
is enhanced using the automatic
brake dif ferential (ABD). If a wheel threatens to spin, PTM brakes it
via ABD and in doing so transfers
more drive torque to the other
wheel on the same axle.
Assisting PTM is Porsche Stabilit y
Management (PSM). Combined,
these systems provide excellent
torque distribution – and there
-
fore outstanding performance –
in all driving conditions.
The benefits of PTM are most
evident in wet and snow y
conditions. In these conditions,
the 911 Turbo models of fer
breathtaking acceleration. In short, PTM provides greater
active safet y and greater
performance, combined with
exemplary balance.

Interior.
Efficient ergonomics is the guid-
ing theme for the interior. The
steering wheel of fers 40 mm of
adjustment for both height and
reach. A multifunction steering
wheel – with or without steering
wheel heating – is available on
request. The distinctively designed gear lever (for the six-
speed manual gearbox) and PDK
gear selector are easy to operate.
Porsche Communication Manage
-
ment (PCM) with a touchscreen is
fit ted as standard, as is the inte -
gral GPS navigation module with
hard drive navigation (page 86).
The new 911 Turbo S models come equipped with an integrated
six- disc CD/ DVD autochanger
and cruise control as standard.
The air- conditioning system with
an active carbon filter is fully
automatic. The leather finish on the seats,
dashboard, doors and rear
side panels is pleasing to the
touch. Available exclusively for
911 Turbo S models as standard
is the choice of t wo -tone leather
interior in either Black and Cream
or Black and Titanium Blue.
The centre console and door
storage compartments provide
storage space for personal items.
Below the passenger airbag are
t wo cup holders and below these
is the glove compartment with
CD storage.
Two 12-volt sockets (including the
cigaret te lighter) provide power
for a range of electrical devices.
Instruments.
The classic Porsche grouping of
five round instruments offers a
clear overview of all key informa -
tion.
The digital display in the centre-
left dial (speedometer) provides
main and trip odometer readings.
The central rev counter, featuring
the ‘turbo’ ‘or turbo S’ logo,
includes the standard on-board
computer display. This multi -
pur
pose field contains a perma -
nent digital speedometer as well
as the upshif t display on manual
models. The following optional information can also be displayed:
boost pressure, average speed,
average fuel consumption, t yre
pressure, current radio station,
navigation instructions and
remaining range till empt y. When
‘Sport ’ mode is selected on
the Sport Chrono Package Turbo
in a 911 Turbo model equipped
with dynamic engine mount
system, the temporary increase
in maximum torque is clearly
indicated by an arrow symbol in
the boost pressure display.
The third display, in the centre-
right dial, shows the time and
outside temperature.
Why do you need huge gestures
when the signs are clear?
Comfort.
An expressive design.
Well conceived technology.
A consistently sporty style.
No gimmicks. Why should the
rules for performance be
any different for the interior?
