2010 PORSCHE CAYENNE air condition

Understatement coupled with
clear statements: lower fuel
consumption, faster acceleration.
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
dual­tube 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 % .

all ­wheel drive. Also connecting
the car to the road are the new
19 ­inch Cayenne Turbo wheels. The chassis on the new Cayenne
Turbo is equipped as standard
with air suspension
featuring self­
levelling and ride ­height control,
as well as Porsche Active Suspen ­
sion Management
(PASM, p. 51).
This electronic damping control
system offers continuous adjust ­
ment 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 new
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 new Cayenne Turbo include
Bi
­Xenon 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.
Based on the same solid
foun
dations as its predecessor,
the new Cayenne Turbo blends
phenomenal performance with
comfort and ef ficiency. 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.

consistently within a specific
temperature range. The engines
in the new Cayenne models are
therefore designed for optimum
cooling.
The V8 engines have an enhanced
coolant management system
offering effective temperature
control throughout the engine.
While 20% of coolant flows longi­
tudinally through the crankcase,
the remaining 80% serves the
cylinder heads using the proven
cross ­flow principle (from hot to
cold).
On all Cayenne models, the piston
heads are cooled using oil ­spray
jets integrated within the main
lubrication system. In addition,
thermal management ensures
that the optimum operating tem ­
perature for the engines is
reached more quickly. This keeps emissions and fuel consumption
low, even when starting from cold.
The entire cooling system is
designed for prolonged heav y
­

dut y use, e.g. of f ­road driving
or heav y towing and carrying
applications.
Lubrication.
The V8 engines use dry ­sump
lubrication to ensure a consistent
supply of oil in all load conditions,
especially in of f ­road terrain.
The oil reservoir is located inside
the engine. This saves on space
and reduces weight.
Oil is circulated around the V8
engines using a demand ­driven
pump. This has been designed for the toughest driving scenarios
on and off road, including per­
formance driving and extreme
gradients.
The V6 engine in the Cayenne has
a wet ­sump lubrication system.
Ensuring a reliable supply of oil,
no mat ter how challenging the
driving conditions.
Direct fuel injection on the
diesel engine (common-rail
injection system).
On the Cayenne Diesel, direct
fuel injection comes courtesy of
a common ­rail injection system.
The injection pressure of up
to 1,800 bar ensures optimum
distribution of the air/fuel mixture
– for greater performance. The
piezoelectric injection valves
provide flexible injection rate

adjustment, using exactly metered
quantities of fuel, with multiple
injections for each power stroke
to deliver smooth combustion.
Cooling systems.
A high ­performance engine can
only maintain its maximum
capabilit y over a long service life
if all components are operating
Direct fuel injection (DFI).
DFI injects fuel directly into the
combustion chamber at up to

120 bar with millisecond precision
using electromagnetic injectors.
The injector position and spray
geometry have been carefully
designed to improve output,
torque, fuel economy and emis ­
sions. The swirling of the fuel as
it enters each chamber increases
the mixing of air and fuel, thereby
enhancing combustion. By form ­
ing the air/fuel mixture directly
in the combustion chamber, DFI
contributes to engine cooling.
As a result, it was possible to in ­
crease the compression ratio and
therefore power and efficiency.

Compression with precision.
Essential for getting right to the point.

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.

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

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.
