2011 PORSCHE CAYENNE traction control

At Porsche, we are continually
changing. Looking for a new and
dif ferent approach. Without ever
losing sight of where we’ve come
from. That ’s how we remain true
to ourselves.
The basic Cayenne concept is
therefore the same. We’ve just
continued to improve it: the
Cayenne is
now lighter – up to
165 kg
1) depending on the speci-
fication
– and also more dynamic,
more comfortable, and closer
to the road than ever before.
Without detracting from the

qualities required for off-road
driving or towing heav y loads.
Its naturally aspirated 3.6-litre
V6 engine features direct fuel
injection (DFI, p. 38), variable
valve timing on both inlet and
exhaust, and a variable resonance
intake manifold – for a generous
output and excellent fuel econ-
omy. In other words: we have
enhanced the performance, while
significantly lowering the weight,
fuel consumption and CO
2 emis-
sions. The figures speak for themselves: maximum torque of
400 Nm, 220 kW (300 hp), a top
speed of 230 km/ h (143 mph)
and the abilit y to accelerate
from 0 to 100 km/ h (62 mph) in
7.5 se conds. With both fuel
consumption and CO
2 emissions
reduced by 20 %.
1), 2) Delivering
this power to the road efficiently,
Porsche Traction Management
(PTM, p. 44) combines active all-
wheel drive
with an electron ically
variable
multi-plate clutch, auto -
matic brake dif ferential (ABD) and
anti-slip regulation (ASR). PTM
enables the perfect distribution of
drive torque to all four wheels,
whether on long straights, through
tight corners or on surfaces with
dif ferent friction coef ficients: for
dynamic handling
and increased
traction. Drive is transmit ted
through a high-performance
six-speed manual gearbox (p. 42),
which ensures optimum progres-
sion through the gears.
In addition to the standard
18-inch Cayenne wheels and
larger brakes, the Cayenne
can be fit ted with the optional Porsche Ceramic Composite
Brake (PCCB, p. 64) – for out-
standing brake performance.
Another key advantage: a total
weight saving of approximately
50 % compared with equivalent
cast- iron discs.
The generous standard equipment
includes partial-leather seats,
climate control, the CDR-31 audio
system with touchscreen, cruise
control and automatic headlight
activation. For added comfort,
there’s also a ‘Welcome Home’
lighting function. When you arrive
at a destination af ter dark, the
headlights remain illuminated for
a user- defined period, lighting
your path from the car.
So, a unique blend of the great
sports performance and unre-
stricted everyday practicalit y that
is t ypical of Porsche. Let ’s be
honest, would you have expected
any thing else?
Everything has changed. Apart from the concept.

1) The unit generates
180 kW (245 hp) and maximum
torque of 550 Nm. The sprint
to 100 km/ h (62 mph) requires
just 7.6 seconds. Top speed
is 220 km/ h (137 mph). Fuel
con sumption now comes in at
just 7.2 l/100 km (39.2 mpg) in
the EU cycle.
2)
Direct fuel injection comes cour-
tesy of a common-rail injection
system. The piezoelectric
injectors now enable multiple
injections at a pressure of up to 2,000 bar, ensuring optimum
distribution of the air/fuel mixture
– for improved dynamics.
The new turbocharger on the
Cayenne Diesel features Variable
Turbine Geometry (V TG, p. 40).
Combined with optimised channel-
ling of the intake air, it enhances
the charging ef fect, thereby
generating a higher output and
impressive torque, even at low
engine speeds.
The standard eight-speed
Tiptronic S includes gearshif t
controls on the steering wheel.

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 standard eight-speed
Tiptronic S, which includes gear-
shif 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 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

the 4.8-litre t win -turbo V8 engine
that delivers 368 kW (500 hp)
and features direct fuel injection
(DFI, p. 38). The car has a top
speed of 278 km/ h (173 mph)
and the benchmark sprint from
0 to 100 km/ h (62 mph) is com-
pleted in 4.7 seconds. Maximum

all-wheel drive. Also connecting
the car to the road are the 19 -inch Cayenne Turbo wheels.
The chassis on the Cayenne Turbo
is equipped as standard with air
suspension featuring self-levelling
and ride-height control, as well
as Porsche Active Suspension
Management
(PASM, p. 51). This
electronic damping control sys-
tem offers continuous adjustment
of the damping forces
on each
wheel – depending on
current
road conditions and driving st yle.
This enables greater car control,
improving safet y and comfort.
Comfort is also key in the
Cayenne Turbo interior. Standard
equipment comprises an interior
package in smooth-finish leather,
a rooflining in Alcantara and an
electrically adjustable steering
column.
Also fit ted as standard: the
BOSE® Surround Sound System,
Porsche Communication
Management (PCM) with navi-
gation module, adaptive sports
seats with comfort memor y package (18-way), Tyre Pressure
Monitoring (TPM, p. 57), auto -
matic headlight activation and
automatically dimming exterior
and interior mirrors.
Exterior features exclusive to
the Cayenne Turbo include
Bi-Xenon main headlights with
Porsche Dynamic Light System
(PDLS, p. 61), larger air intakes
and a distinctive ‘power dome’ on
the engine lid – a clear reference
to the enormous potential within.
Following our long established
principles,
the Cayenne Turbo
blends phenomenal performance
with outstanding comfort and
efficiency. It does so in st yle but
without ever compromising on
any one in particular. Because we
believe that less can also mean
more.
Reduced weight, lower fuel consumption, fewer emissions.
At Porsche, we believe less is more.

The 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 maintain drive. As well as en-
hancing traction and active safety,

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, 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

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 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.
