2008 PORSCHE CAYENNE lock

Model range
Exceptional performance.
What else would you expect from a Porsche?
The Cayenne.
A high-performance six-speed
manual gearbox is standard
equipment. The optional six-speed
Tiptronic S includes gearshift
controls on the steering wheel.
It is also equipped with standby
control for better fuel economy
(see page 64).
The powerful brakes increase
active safety in all driving scenarios.
The black-finish calipers are unique
to the V6 model.
With its precision steering and
sports chassis setup, the Cayenne
is agile and responsive. Using
Porsche Traction Management (PTM)
and Porsche Stability Management
(PSM), power is transmitted through
the permanent all-wheel drive with
efficiency, precision and safety. In
difficult terrain, the electronically
variable centre differential combines
with the anti-slip regulation (ASR)
and automatic brake differential
(ABD) to maintain optimum traction
at all times. This ability is enhanced
in low-range mode, where all gear
ratios are reduced. As a result,
the car remains mobile in soft
ground and performs better when
towing a heavy trailer load. For
the toughest off-road conditions,
the electronically variable centre
differential can be fully locked while
in low-range mode using the PTM
control on the centre console.
The torque split is then fixed with
38 % of drive being transmitted
to the front wheels and 62 % to
the rear.
For extreme off-road use, there’s
the optional Off-road Technology
package. As well as increasing
underbody protection, it includes
an electronically variable rear
differential (see page 89). This
differential can also be manually
locked to increase off-road
traction.
The Cayenne is an excellent on-
road performer with a wide range
of other talents: off-road capability,
comfort, safety, sporting style and
practicality.
Its powerful V6 engine features
direct fuel injection (DFI), variable
valve timing on inlet and exhaust
and a variable resonance intake
manifold. The results: generous
performance and excellent fuel
economy.
The 3.6-litre engine develops
213 kW (290 hp) at 6,200 rpm.
Maximum torque is 385 Nm
from as low as 3,000 rpm. With
a manual gearbox, it requires
8.1 seconds to reach 100 km / h
(62 mph). Maximum speed is
227 km / h (141 mph).
Press the standard ‘Sport’ button
and the engine management is
adjusted to maximise throttle
response.

Power is the product of efficiency.
Lightweight alloy engine construction.
‘Less is more’ – less weight, more
performance – is a key principle of
Porsche design.
The V8 Cayenne engines have
a ‘closed-deck’ aluminium
crankcase and lightweight
aluminium bedplate. The cylinder
block and its associated coolant
channels are therefore a fully
enclosed system. This not only
reduces the weight of the engine,
it also improves its dimensional
stability. Since the engine is
stronger, it also has a longer
service life.
Other major lightweight compon-
ents include cast aluminium
pistons and aluminium cylinder
heads. On the Cayenne Turbo, the
pistons are forged to compensate
for the higher loads.
The Cayenne V6 has a cast-iron
crankcase and one-piece cylinderheads in die-cast aluminium. This
combination produces high power
output while reducing the weight
of the engine.
Drive
Lightweight construction used on the V8 engines
Consistent performance and a longer service life.
Engine cooling system.
Each engine remains within its
optimum temperature range at
all times. Clearances throughout
the engine are extremely small,
thereby reducing wear. The entire
cooling system is designed for
prolonged
heavy-duty use, e.g.,
off-road driving or heavy towing
and carrying applications.
Emissions, noise and fuel
consumption remain low, while
power and torque are improved.
Lubrication.
The V8 engines use dry-sump
lubrication to ensure a consistent
supply of oil in all load conditions.
The oil reservoir is located inside
the engine. As well as saving
space and reducing weight, the oil
is always there where it’s needed.
Oil is circulated around the
V8 engines using a demand-driven
pump and two-stage scavenging
system, providing optimum
delivery in even the toughest
scenarios.
The V6 engine has a wet-sump
lubrication system that is
also designed for challenging
conditions, e.g., performance
road driving or extreme off-road
gradients.
A high-performance engine can
only maintain its optimum capability
over a long service life if all com-
ponents are operating consistently
within a specific temperature
range.
The V8 engines have an optimised
coolant management system offering
effective temperature control
throughout the engine. While 20 %
of coolant flows longitudinally
through the crankcase, 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 in the main lubrica-
tion system.

Drive
Applying power with intelligence.
Porsche Traction Management (PTM).
If one wheel loses traction, PTM
utilises the ABD function to apply
the corresponding brake. As a
result, more drive is automatically
transferred to the opposite wheel.
If both wheels on one axle lose
traction, ASR modifies engine output
to maintain drive.
All PTM functions are fully automatic.
All you have to do is choose high-
range mode for road and track or
low-range mode for greater off-road
traction. These are selected using
a single control on the centre
console. In low-range mode, the
gearing is reduced to enhance
off-road manoeuvrability or to
increase road traction when towing
heavy loads.
be automatically varied to match
changing driving conditions. For
the toughest off-road terrain, the
differential can be locked via the
PTM control on the centre console.
Other major features in PTM include
a two-speed transfer gearbox (with
low-range gearing for off-road use),
an automatic brake differential
(ABD) and anti-slip regulation (ASR).
Combining a range of systems
and functions, Porsche Traction
Management (PTM) actively
distributes engine torque precisely
where it’s needed most.
At the heart of PTM is a permanent
all-wheel drive system with electron-
ically variable centre differential.
The standard torque split of 38 %
to the front and 62 % to the rear canCombined, they enable exceptional
performance and vehicle control in
normal road driving or off-road
terrain.
PTM uses the ABD and ASR
functions to achieve dynamic
handling and increased traction.

Off road
Applying power with sensitivity, protecting with strength.
Off-road Technology package.
The rear differential enables
optimum distribution of engine
torque in difficult off-road terrain.
A fully automated part of the
all-wheel system, its primary
function is to optimise traction.
If one of the rear wheels begins
to lose grip, the differential varies
the torque transmitted through
each drive shaft, thereby restoring
traction. Available as a factory-fitted
option on all Cayenne models, the
Off-road Technology package*
incorporates an electronically
variable and lockable rear
differential as part of the standard
all-wheel drive system. Other
features include high-strength
rock-rails with integrated skid
plates, a reinforced engine-bay
guard, enhanced protection for
the fuel tank and rear axle, and
a second towing lug.In low-range mode, the rear
differential can be manually
locked using the main off-road
control on the centre console.
In this state, both rear wheels
receive the same amount of
torque.
For additional off-road protection,
optional wheel-arch extensions
(black finish) and running boards*
with integrated skid plates are
available.
