2010 PORSCHE CAYENNE lock

Boasting outstanding perform­
ance and ef ficiency, the new
Cayenne Diesel is ideal for longer
journeys – offering high levels
of torque, while fuel consumption
remains low.
Its 3.0 ­litre V6 turbo ­diesel engine
is powerful and refined. The unit
generates 176 kW (240 hp) and
maximum torque of 550 Nm.
The sprint to 100 km/ h (62 mph)
requires just 7.8 seconds. Top
speed is 218 km/ h (135 mph).
In addition, both fuel consumption
and CO
2 emissions have been
reduced by up to 20 %.

Direct fuel injection comes
courtesy of a common ­rail

injection system. The injection
pressure of up to 1,800 bar en ­sures optimum distribution of the
air/fuel mixture – for enhanced
dynamics. The piezoelectric
injection valves enable multiple
injections for each power stroke
to deliver efficient combustion.
The turbocharger on the new
Cayenne Diesel features Variable
Turbine Geometry (V TG, p. 40),
generating a higher output and
impressive torque, even at low
engine speeds.
Now standard equipment, the
new eight
­speed Tiptronic S
includes gearshift 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
performance driving with em­
phatic acceleration. Porsche Traction Management

drive with self ­locking centre
dif ferential transmits the car’s
power to all four wheels with
optimum precision and control.
Available as a no ­cost option,
the 100 ­litre fuel tank enhances
the range to well over 1,000 km
(approx. 620 miles) while keeping

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 main ­tain drive. As well as enhancing
traction and active safet y,

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.

Off ­road Mode 2 – for even great ­
er traction on dif ficult terrain,
the multi ­plate clutch can be fully

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.

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.

PSM has three additional func­
tions that help reduce braking
distances. If the throt tle pedal
is released suddenly, PSM

automatically readies the braking
system. The pressure in the
brake lines is marginally increased,
bringing each of the pads into
light contact with the correspond ­
ing disc. If the driver goes on
to apply the brakes, the calipers
respond more quickly and the
braking distance is reduced. In an emergency stop – i.e. when
the pressure on the brake pedal
exceeds a certain threshold –
the brake assist function uses the
PSM hydraulics to apply maximum
braking force at all four wheels.
For added safet y, the system
also readies the brakes whenever
a decreasing distance to the
vehicle in front is detected. The
optional adaptive cruise control
and PSM interact to prefill the
brakes.
Even if adaptive cruise control is
inactive, the system registers the
speed of the vehicle in front and
automatically readies the braking
system. In addition, the system
alerts the driver to the decreasing distance by briefly tugging on
the brakes.
PSM also features a trailer
stabilisation function – for a
significant contribution to car
and trailer safet y.
Within the laws of physics, it
compensates for load transfer
caused by throt tle and brake

inputs up to the maximum degree
of lateral acceleration. It also en ­
hances the car’s driving dynamics
and directional stabilit y when
accelerating on inconsistent road
surfaces.
Other features include a special
control strategy in the ABS
for braking on loose surfaces.
By briefly locking the wheels, a wedge is formed ahead of each
t yre which provides additional
purchase to help slow the car,
e.g. on gravel or snow.
For a more involving driving

experience, PSM can also be
disabled, but remains active in
the background.

this information, it is possible to
calculate the actual direction of

the car begins to oversteer or

braking on individual wheels to

PSM can also intervene in the
engine management system to
temporarily modif y the amount of
drive transmit ted to the wheels.
