engine is now more powerful and
refined, and approximately 20 kg

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.

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,

Torque is distributed bet ween the

With the aid of on -board sensors,

ously monitored and the front /

sure is applied to the inside rear

motion of the car, thereby im-
proving its cornering dynamics.

Available on the Cayenne,

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, 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
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 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.

With the help of Porsche Traction

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.

PT V Plus optimises steering re-

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

accele ration of the car. Using
this information, it is possible to
calculate the actual direction of
travel at any given moment. If
the car begins to oversteer or
understeer, PSM applies selective
braking on individual wheels to
restore stabilit y. If necessar y,
PSM can also intervene in the
engine management system to
temporarily modif y the amount of
drive transmit ted to the wheels.
