differential PORSCHE CAYNNE 2010 1.G Information Manual

The Porsche ‘S’ has long been
a mark of heightened sports per­
formance and abundant reserves
of power. On the Cayenne S, it
also stands for strength, agilit y
and efficiency.
At the heart of the car is a natur­
ally aspirated 4.8 ­litre V8 engine
featuring direct fuel injection
(DFI, p. 38), VarioCam Plus (p. 37)
and a t wo ­stage intake manifold.
This helps to keep fuel consump ­
tion and emissions low, while
ensuring maximum output. In
short: 294 kW (400 hp), maximum
torque of 500 Nm and a top
speed of 258 km/ h (160 mph).
The Cayenne S accelerates from
0 to 100 km/ h (62 mph) in as
lit tle as 5.9 seconds. Fuel con ­
sumption has been reduced by
up to 23 % and CO
2 emissions by
as much as 26 %.
1), 2) The weight
of the car has also been lowered
by 180 kg
1). Drive is transmit ted to the road
with smoothness and precision
by the eight
­speed Tiptronic S,
which is now standard equipment
and includes gearshif t controls
on the steering wheel. The result:
optimum use of the available
power reserves.
Of course, to apply exceptional
power like this ef fectively, it
needs to be harnessed and con ­
trolled. For example, by Porsche
Traction Management (PTM,
p. 44). On the new Cayenne S,
this active all ­wheel drive system
features an electronically variable,
map ­controlled multi ­plate clutch,
an automatic brake differential
(ABD, p. 44) and anti ­slip regu­
lation (ASR, p. 44). Working
in conjunction with advanced
Porsche Stabilit y Management
(PSM, p. 66), PTM ensures the
required torque split in every
driving scenario. On or of f road. During performance driving,

as well as on leisurely journeys
or when towing heav y loads.
The black slats on the air intakes
make them appear larger, and
the car wider. Other distinctive
features include the 18 ­inch
Cayenne S III wheels.

the new Cayenne S holds true.

sensors are used to measure a
range of values, including the
rotational speed of all four wheels,
the lateral and longitudinal
acceleration of the car, and
the current steering angle.
If, for example, the rear wheels
threaten to lose traction under
acceleration, a greater proportion
of drive torque is automatically
transmit ted to the front axle by a more positive engagement of
the multi
­plate clutch. In addition,
ASR minimises wheel spin. During
cornering, the required level of
engine torque is distributed to the
front wheels to ensure excellent
lateral stabilit y.
In conjunction with advanced
Porsche Stabilit y Management
(PSM, p. 66), PTM ensures the
perfect distribution of drive
torque for optimum traction in all road scenarios, whether on
long straights, through tight cor
­
ners or on surfaces with dif ferent
friction coef ficients. If one of the
wheels is about to lose traction,
PTM uses the ABD function to
apply the corresponding brake.
As a result, more drive is auto ­
matically transferred to the op­
posite wheel. If both wheels on
one axle are in danger of slipping,
ASR immediately intervenes and
modifies engine output to main ­tain drive. As well as enhancing
traction and active safet y,

Torque is distributed bet ween the
front and rear axles by means of
the electronically variable multi
­
plate clutch. For the toughest
off ­road terrain, the differential
can be locked using the PTM
control on the centre console.
With the aid of on ­board sensors,
the status of the car is continu ­
ously monitored and the front /
rear split is adjusted to match
changing driving conditions. The

Drive systems and chassis | Transmission · 45

Available on the Cayenne,
Cayenne Diesel, Cayenne S

and Cayenne Turbo, this function
readies the car for of f ­road use
or reverts the set ting to normal
road driving.
In Of f ­road Mode 1, for example,
the maps for all relevant
systems, e.g. ABS, are adapted
to provide optimum traction. In
addition, Porsche Hill Control

is activated and High Level I is
selected on vehicles featuring air
suspension with PASM. If that ’s
not enough, the air suspension
can be raised further to High
Level II to increase the approach/
departure angle and wading depth.
Push the of f ­road control forward
again on the Cayenne, Cayenne S
and Cayenne Turbo to activate
Off ­road Mode 2 – for even great ­
er traction on dif ficult terrain,
the multi ­plate clutch can be fully
locked.
The electronically variable rear
differential on the optional
Porsche Torque Vectoring Plus
(PT V Plus) is integrated within
the all ­wheel drive system. This
automatically ensures the opti ­mum distribution of drive torque
on particularly uneven surfaces.
If one of the rear wheels begins
to slip, the rear dif ferential varies
the amount of torque transmit ted
through each drive shaf t, thereby
restoring traction. In Of f
­road
Mode 3, the rear dif ferential can
be manually locked using the main
of f ­road control. Then both rear
wheels receive the same amount
of torque, regardless of surface
conditions. The optional PDCC
(p. 53) enables greater wheel
articulation in all three modes,
improving traction still further.
For effective prevention of dam ­
age to the underside of the car,
all new Cayenne models can be
equipped with optional of f ­road
underbody protection comprising
rock rails with integrated skid plates, a reinforced engine
­bay
guard, additional protection
for fuel tank and rear axle, and
a second towing lug.
Operating concept.
With the help of Porsche Traction
Management (PTM), the Cayenne
can cope with even the most
demanding of f ­road scenarios.
Simply move the main of f ­road
control on the centre console
forward or backward to select
one of up to three off ­road
modes (depending on the model).
Steep ascents leading to snow
­
covered mountain lodges, boggy
ground or muddy, loose surfaces
– all situations that the Cayenne
handles superbly with intelligent
all ­wheel drive. The drive systems
featured on the new Cayenne
models deliver exceptional torque.

Porsche Active Suspension
Management (PASM).
PASM is an electronic damping
control system. It of fers con­
tinuous adjustment of individual
damping forces based on current
road conditions and driving st yle.
During performance driving or
heav y of f ­road use, there is an
increased tendency for the body
to sway. PASM prevents this from
happening, thereby improving
stabilit y and occupant comfort. PASM has three setup modes:
‘Comfort ’, ‘Normal’ and ‘Sport ’.
Whichever one you select, the
system uses a series of sensors
to monitor the movement of the
body. It also gathers data on
lateral acceleration, steering
angle, brake pressure and engine
torque and modifies the damping
force on each individual wheel

in accordance with the selected
mode. PASM remains active at all times.
It automatically adapts to the
prevailing driving conditions,

enabling greater car control and
improving comfort and safet y.
Optional for the new Cayenne,
new Cayenne Diesel, new
Cayenne S and new Cayenne S
Hybrid. Standard on the new
Cayenne Turbo: air suspension
with PASM.
This transfers drive torque to the
outside rear wheel which supports
the steering motion of the car,
thereby improving its cornering
dynamics.
At slow and medium speeds, PT V
Plus considerably enhances agilit y
and steering precision. At high
speeds, during fast cornering and
under wheel spin, the mechanical
limited ­slip rear differential
ensures additional stabilit y. Also
on variable ­grip surfaces, in the
wet and on snow, PT V Plus –
combined with Porsche Traction
Management (PTM) and Porsche
Stabilit y Management (PSM) –
provides a major contribution to
active safety.
Porsche Torque Vectoring Plus
(PTV Plus).
A new system for enhancing
driving dynamics and stabilit y,
PT V Plus offers variable distribu ­
tion of engine torque to the rear
wheels and mechanical limited ­
slip rear dif ferential. Depending
on the steering angle, steering
speed, throt tle pedal position,
yaw velocit y and vehicle speed,
PT V Plus optimises steering re ­
sponse and precision by applying
brake pressure to the left or right
rear wheel, as required.
Specifically, this means that when
entering a corner at high speed,
moderate brake pressure is
applied to the inside rear wheel.
