2009 PORSCHE 911 wheel torque

Porsche Torque Vectoring (PTV).
Porsche Torque Vectoring (stand-
ard on 911 Turbo S models,
optional for 911 Turbo models), with variable torque distribution
to the rear wheels and a mechan
-
ical limited-slip rear differential,
is a system that actively enhances
vehicle dynamics and stabilit y. As a function of steering angle
and steering speed, accelerator
pedal position, yaw rate and

vehicle speed, PT V is able to
improve steering response and steering precision significantly

by specific braking of the right or
left rear wheel.
In simple terms, this means that
when the car is driven assertively
into a corner, moderate brake
pressure is applied to the inside
rear wheel. Consequently, excess
drive force, which varies depend -
ing on the braking force applied
to the inside rear wheel, can be
distributed to the outside rear
wheel, and a rotational pulse (yaw
movement) is generated around
the vehicle’s vertical axis. This
assists the steering input and
results in a more assured steering
manoeuvre.
At low and medium vehicle
speeds, the system significantly
increases agilit y and steering
precision, whilst at high speeds,
and in combination with the
mechanical limited-slip differential,
it additionally ensures greater
driving stabilit y. The system, combined with

Porsche Traction Management
(PTM) and Porsche Stabilit y
Management (PSM), also puts

its stabilising ef fect to good use
on road surfaces with varying
levels of grip and on snow and ice.
As PT V increases the car’s
dynamic performance, the system
remains active when driving
on the racetrack, even if PSM
has been deactivated.
Where
efficien cy is concerned,
this
enhanced performance and
stabilit y are achieved without the
need for any additional compo -
nents, apart from the mechanical
limited-slip rear differential. In
other words, a more enjoyable
drive with no additional weight.

Sport Chrono Package Turbo
with dynamic engine mount
system.
The Sport Chrono Package Turbo
with dynamic engine mount
system is standard on 911 Turbo S
models and available as an
option for 911 Turbo models.

This integrated system provides
simultaneous enhancement for
engine, chassis and transmission.
Key features include a digital
and analogue stopwatch on the
dashboard, a performance dis -
play, a personal memor y function
in the Porsche Communication
Management (PCM), the SPORT
but ton and – in combination with
PDK – the SPORT PLUS but ton,
and an additional display on the
steering wheel which informs the
driver if the SPORT but tons and Launch Control have been acti
-
vated. The 911 Turbo models
additionally of fer the ‘overboost ’
function. This is how it works:
When ‘Sport ’ mode is selected,
the engine management system
creates a much more aggressive
response to pedal inputs. To do
this, it implements an alternative
throt tle map which relates the
pedal position in the foot well to
a wider angle of opening in the
throt tle body. In higher gears, it
uses a hard rev- limiter to protect
the engine under power.
In the 911 Turbo models, under
full acceleration, the maximum
boost pressure in the lower and
medium speed ranges is now
temporarily increased by approx -
imately 0.2 bar. As a result,
engine torque is boosted by 50 Nm to a maximum of 700 Nm for a
limited period. (The 911 Turbo S
models are configured to operate
with a higher boost pressure level,

which means that their maximum
torque is always 700 Nm.)
In addition to the engine, ‘Sport ’
mode is enabled in the standard
Porsche Active Suspension
Management (PASM) suspension.
The dampers become firmer,
enabling faster turn - in as well as
bet ter contact with the road.
In automatic mode of PDK,
the basic gearshif t pat tern is
switched to high-performance
mode. The gear change action is
virtually instantaneous, while the
shift points are timed for maxi -
mum acceleration. Lif t of f the
throt tle – even at high revs – and
the system automatically shif ts
down to apply engine braking. In
manual shif t mode, gear chang -
ing is faster and more dynamic.
Porsche Stabilit y Management
(PSM) is also adapted, with the
intervention threshold raised. As
a result, the car has a more natu -
ral response to lateral and longi -
tudinal forces. Cornering agilit y
is greatly enhanced, when both braking to turn in and applying
power on exit – particularly

in low-speed bends. For even
greater driving pleasure.
For maximum manoeuvrabilit y,
PSM can be partially disabled
while the car is still in ‘Sport ’
mode. PSM simply monitors the
forces acting on the car and
will only intervene in the most
critical scenarios, e.g. when ABS
assistance is required on both
front wheels.
In conjunction with PDK (standard
on 911 Turbo S models), the
Sport Chrono Package Turbo with
dynamic engine mount system
has t wo additional functions that can be activated via the SPORT
PLUS but ton, for a sport y drive
that borders on a motorsport
experience.
The first function is ‘Launch
Control’, which, for example
when per forming laps, helps you
achieve optimum acceleration
from a standing start, a racing
start in other words.
The function works like this:
press the SPORT PLUS but ton
when the transmission is in ‘D’
or ‘M’. Then, with your lef t foot,
press the brake pedal and accel -
erate fully with the right foot.
The car recognises ‘Launch’ mode
from the accelerator kickdown action and adjusts the engine
speed to the optimum level,
which is around 5,000 rpm. At
the same time, boost pressure
is increased to approximately

0.5 bar, engine torque is
increased and the clutch is
applied lightly. ‘Launch Control’
now appears in the steering
wheel display. Now release the
brake as quickly as you can –
and feel the acceleration power
unleashed to the road.

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?
