2011 PORSCHE CAYENNE steering

Boasting outstanding perform-
ance and ef ficiency, the Cayenne
Diesel is ideal for longer journeys

while fuel consumption remains

Its new 3.0 -litre V6 turbo - diesel
engine is now more powerful and
refined, and approximately 20 kg
l i g h t e r.
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.
Transmit ting the high torque
of the Cayenne Diesel smoothly
and ef fectively, the eight gears
are designed to facilitate both
economical driving
with low fuel
consumption and

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.

features include the 18-inch

clear statements: lower fuel

Supreme engineering that speaks
for itself. In short, every thing
you’d expect from a Turbo.
Another clear statement is the
distinctive sound from the t win
dual-tube tailpipes. Produced by
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
torque is 700 Nm. Here too, fuel
consumption has been reduced
by
23 % and CO2 emissions by
2 5 % .

Optimum traction and safet y are
provided by Porsche Traction

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.

A special bat tery management

a result, the life of the bat tery is
optimised and its suitabilit y for
everyday use ensured, while

ent on the output provided by
the combustion engine, such as
climate control, power steering

output from the engine, these
functions remain active when the
car is running in electric mode or
when it is ‘coasting’ or gliding

In summary: despite its six-
cylinder powerplant, the
Cayenne S Hybrid offers per-
formance levels that are com-
parable with an eight-cylinder
unit – but with significantly lower
fuel consumption.
Also when it comes to hybrid
drives, we’ve taken a completely
new path. Hardly surprising really,
with a technology this convincing.

it can charge the bat tery under

The hybrid system features a

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,
