2011 PORSCHE CAYENNE wheel torque

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.

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

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 %.

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 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 Cayenne S Hybrid has a
3.0 -litre V6 supercharged engine.
The charging effect of the
compressor ensures high levels
of torque, even at low engine
speeds. The unit generates an
output of 245 kW (333 hp).
440 Nm of torque is available
bet ween 3,000 and 5,250 rpm,
enabling a low-rev, economical
driving st yle while offering
exceptional reserves of power.
At 288 volts, the electric machine
has a maximum output of
34 kW (47 hp). The benefits of
the synchronous motor with
inner rotor design are extremely
compact dimensions and high
levels of efficiency. It also acts as

a starter motor and alternator.
Working in tandem, both units
provide a total output of 279 kW
(380 hp) and maximum torque
of 580 Nm, propelling the car
from 0 to 100 km/ h (62 mph) in
just 6.5 seconds. These are the
levels of acceleration you would
usually expect from an eight-
cylinder unit, but with fuel con-
sumption of under 8.2 l/100 km
(34.4 mpg) in the EU cycle.

On the parallel full hybrid system,
the electric machine is integrated
directly into the drivetrain. The
hybrid module is situated bet ween
the transmission and the com -
bustion engine. The engine is
engaged and disengaged using
a specially designed decoupler.
The electronic engine manage-
ment system receives all infor-
mation on the driving and energy

the future.
With the Cayenne S Hybrid, our
primary focus was on meeting
customer requirements in
terms of athleticism and greater

The drive system of the
Cayenne S Hybrid.
Hybrid drives are suitable for use
in a wide range of scenarios. On
road, of f road or on the track – to
us, it ’s about using technology in
the most intelligent way. Porsche
Intelligent Performance has
enabled us to introduce hybrid
technology into a variet y
of different vehicle concepts.

The clearest proof of this is the
super sportscar of the future –
the 918 Spyder. The electric
machines in its plug-in hybrid
system work in conjunction with
the high rpm engine to deliver
exceptional performance with
incredibly low fuel consumption.
Another example is the 911 GT3 R
Hybrid. With its front-wheel hybrid
drive and fly wheel storage sys-
tem, it is an extremely modern
interpretation of a thoroughbred

It shuts of f the combustion
engine and switches it back on.
Thanks to the ultra-fast decoup-
ler and instantaneous engine
start-up, all of this goes un-
noticed by the driver.
Under mod-
erate
acceleration, the electric
machine can power the vehicle
independently using electricit y
alone. For example, for driving
quietly through residential areas
.
In
addition, it can be used to
boost
performance – for even
faster acceleration.
The parallel full hybrid concept
also comes into its own during
performance driving. When
the Cayenne S Hybrid is driven
at high speeds and on overrun,
the combustion engine is automatically disengaged from
the drivetrain and shut off: the
car
continues to ‘coast’ along.
Engine drag and the associated
losses are eliminated and
efficiency is increased at speeds
of up to 156 km/ h (97 mph).
The ‘e-power’ function expands
the range in which the vehicle
can be run solely on electric
power, when heading out of a
residential area, for instance.

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,
