2010 PORSCHE CAYMAN S Information Manual

Chassis
It’s not always better
to take the direct route.
If you have a spirited nature
like the Cayman models, you will
need a chassis that can cope
with the challenges of the road
ahead – and master them with
precision. How is this achieved? All components must be the

perfect match. There’s only one
goal: to be able to fully express
one’s desire for performance.

Light weight spring-strut front axle on the Cayman SLight weight spring-strut rear axle on the Cayman S
struts, front and rear. The spring
and damper unit and the anti-roll
bar unit have been tuned for
exceptional driving dynamics
combined with a high level of
driving comfort. For Porsche, that
is not a contradiction. During Driving stabilit y is excellent, even
in the event of considerable load
changes – thanks not least to

the vehicle’s generous track width.
High levels of safet y and a consist -
ently dynamic driving experience
are the result.Chassis.
The Cayman models follow a
clear line. Their own. Even when it
comes to the chassis. The driver’s
connection to the road is an
essential priorit y at all times, fast lane changes and through
tight corners, this chassis is in its
element. Thanks to the mid- engine
layout and the construction of

the bodyshell, roll and pitch are
practically eliminated. The chassis
responds with absolute precision
along with the delivery of the
engine’s power.
For this reason, the Cayman

models are equipped with
a light weight suspension with
transverse links and spring to acceleration and braking. The
light weight construction keeps
the vehicle gross weight and the
weight of the unsprung masses
low. Virtually all moving axle parts
are made of aluminium.
An expression of agility on the road
that is bound to leave you open-mouthed.

available steering wheels, please

and safet y.Steering.
What use is a perfect suspension
setup without perfectly tuned
steering? For Porsche, this would
be inconceivable. The solution is
a steering system that works with
as much precision and immediacy
as the chassis itself and, thanks to
the power assistance, steering
Wheels.
The Cayman is fit ted with
17-inch wheels as standard. The
star-shaped design expresses
sheer sportiness and allows
an eye- catching view of the brake
calipers. The Cayman S is fit ted
with large, 18-inch wheels as
standard and the turbine-like
arrangement of the spokes gives
the car an extremely powerful
look. 19 -inch wheels are available
for both models on request.
All available wheels are equipped
ef fort is reduced to a comfortable
level. Around the straight ahead
position, such as during motorway
driving, the ratio is less direct
with no loss of agilit y or feedback.
The greater the steering angle,

the more direct the steering ratio.
This is particularly noticeable
through tight bends and when
parking and provides a high
with anti-thef t protection. A
selection of alternative wheels,
such as the 19 -inch 911 Turbo II
wheel, is featured on page 117.
Tyre Pressure Monitoring (TPM).
The optional Tyre Pressure
Monitoring (TPM) sends warnings
to the on -board computer’s
display screen in the event of low
t yre pressure. The driver can
check the pressure in all four
t yres from the instrument cluster.

Mechanically locking rear
differential.
Are you a fan of sport y driving? In
your spare time, do you enjoy the
occasional outing on the racetrack?
Then you shouldn’t do without the
optional mechanically locking rear
differential available in conjunction
with 18-inch or 19-inch wheels.
It further enhances the traction of
the driven rear wheels on uneven
roads and when accelerating out of
tight bends, and the damping of
load-change reactions during
fast cornering is reduced. Road
holding at the limits of perform -
ance is even more impressive. The
car holds its course bet ter and so
PSM intervenes less often.
In other words, sheer driving
pleasure and faster lap times.
Porsche Active Suspension
Management (PASM).
The optional PASM is an electronic
damping control system.
PASM actively and continuously
regulates the damping force
for each wheel according to the
road conditions and driving
st yle. In addition, the suspension
is lowered by 10 mm.
The driver can select bet ween
t wo dif ferent modes: ‘Normal’
which is a blend of performance
and comfort, and ‘Sport ’
where the setup is much firmer.
Depending on the mode selected,
therefore, PASM is sportier
or more comfortable than the
standard chassis. The PASM
control unit evaluates the driving
conditions and modifies the
damping force on each of
the wheels in accordance with
the selected mode. Sensors monitor the movement

of the vehicle body, for example,
under heav y acceleration and
braking or on uneven roads. The
control unit tunes the dampers
to the optimum hardness for the
selected mode to reduce roll and
pitch still further and to increase
contact bet ween each individual
wheel and the road.
In ‘Sport ’ mode, the suspension
is set to a harder damper rating.
On uneven roads, PASM immedi -
ately switches to a softer rating
within the ‘Sport ’ setup range,
thereby improving contact
bet ween the wheels and the road.
When the road surface improves,
PASM automatically reverts
to the original, harder rating.
If ‘Normal’ mode is selected and
the driver’s st yle becomes more
assertive, PASM automatically
switches to a harder rating
within the ‘Normal’ setup range.
Damping becomes harder, and
driving stabilit y and road safet y
are increased.

For maximum dexterit y, PSM
can be set to standby while the
car is still in ‘Sport ’ mode (p. 72).
For safet y, it is set to intervene
automatically only when ABS
assistance is required on both
front wheels.
A key component of the Sport
Chrono Package is the swivel-
mounted stopwatch in the centre
of the dashboard with analogue
and digital display.
In combination with Porsche
Doppelkupplung (PDK), the Sport
Chrono Package offers t wo addi -
tional functions that are activated
by the SPORT PLUS but ton.
First, ‘Launch Control’, which
ensures you achieve the fastest
possible rate of acceleration from
a standing start – on the racetrack,
for example. ‘Launch Control’ is

operated via the SPORT PLUS
but ton with the ‘D’ or ‘M’ drive
position selected. Whilst the driver
depresses the brake pedal
with the lef t foot, the right foot
depresses the accelerator pedal
to the floor. With the accelerator
in the kickdown position, the
delayed until the upper rev range.
The shif t times are shorter, the
gear changes sportier. At low
rates of deceleration, the system
initiates a swif ter, brake-induced
downshift. In manual mode,

gear changes are faster and more
dynamic. In ‘Sport ’ mode, the
PSM system (p. 72) intervenes
later for increased longitudinal and
lateral dynamics. PSM now af fords
greater manoeuvrabilit y under
braking and exit acceleration,
especially at low speeds.
Sport Chrono Package.
Do you think driving a Porsche
should be an even more involving
experience than it is already? Your
wish is our command. On request,
we can equip your vehicle with the
Sport Chrono Package, which is
available for both of the Cayman
models. Its functions enable even
sportier tuning of the engine and
chassis and guarantee even more
driving pleasure.
Selecting the SPORT but ton
on the centre console activates ‘Sport ’ mode, which makes
throt tle response significantly
more immediate, adjusts the
rev-limiter to a harder set ting,

and tunes the engine dynamics
for performance driving.
The optional Porsche Active
Suspension Management (PASM)
also switches to ‘Sport ’ mode,
which of fers harder damping
and more direct steering and,
therefore, bet ter road holding.
With the optional PDK in automatic
mode, gearshif t points are system detects the driver’s
request for Launch mode and revs
the engine to an optimum speed
of approximately 6,500 rpm.
Engine torque increases and the
clutch closes slightly. The message
‘Launch Control’ appears on
the display on the steering wheel
for PDK. The driver now quickly
releases the brake – and prepares
for maximum acceleration.
Second, the ‘motorsport- derived
gearshif t strategy’. Using this, PDK
is geared up for maximum shif t
speed, the shortest possible shif t
times and optimum shif t points
for maximum acceleration – for
uncompromising performance.
Sport Chrono Package Plus.
On request, the optional Porsche
Communication Management
(PCM, p. 92) can be combined
with the Sport Chrono Package
Plus. In addition to the functions
of the Sport Chrono Package,
it includes a personal memory
function, which can be controlled
using PCM, and a performance
display for evaluating lap times.

Safety
A controlled offensive.
Even on the defensive.
The Cayman models are
uncompromising sportscars. In
every respect. The same applies
to safet y. Active as well as
passive. Trust alone is not enough.
You have to be confident about
your vehicle. So we’ve taken care
of it. Any thing else just wouldn’t
be Porsche.

Night design, front
There can be no driving pleasure without peace of mind.
Introducing the safety features of the Cayman models.
The low front fog lights of fer

outstanding illumination and a
high -level third brake light is
neatly integrated into the rear
window. LED technology is used
in the taillights, brake lights and
rear fog light to provide bet ter
illumination and respond more
quickly to driver input.
Bi-Xenon headlights with
dynamic cornering lights and
LED daytime running lights.
Available as an option for the
Cayman models are Bi-Xenon
headlights including dynamic
cornering lights and LED day time
running lights. Bi-Xenon headlights
are around t wice as powerful as
halogen headlights so they of fer
improved visibilit y and illuminate
the road more evenly. In fact, they
are so ef fective that fog lights are
no longer necessary. A headlight
cleaning system is built-in.
Dynamic cornering lights of fer
particularly effective illumination
of the road ahead, particularly
through bends. Sensors continu -
ously monitor the speed, lateral
acceleration and steering
lock and, from these variables,
calculate the course of the bend.
This determines the angle of
the dynamic cornering lights, with
the lights able to swivel towards
the inside of the bend up to a
limit of 15 degrees, even with the
main beam switched on.Active safety.
Active safet y is a topic that
Porsche actively supports. With
generous safet y margins, even
the suspension tuning makes a
decisive contribution. Optimum
acceleration enables rapid
overtaking and optimum braking
minimises stopping distances.
Safe contact with the road is
provided not only by the wheel/
t yre combination but also by the auto - deploying bi-plane rear

spoiler and aerodynamic front end.
Another important standard
safet y feature is Porsche Stabilit y
Management (PSM, p. 72).
See and be seen. This is a
slogan that t ypifies the headlights
concept. The design is unmistak -
able, the brightness unmissable.
The halogen headlights with LED
position lights in the front light unit
ensure clear visibilit y at all times.

Standard brake unit (Cayman)
Braking system.
The acceleration of the Cayman
models is impressive. Even

more impressive, perhaps, is the
vehicle’s maximum braking power,
which comfortably tames the
power of the engine.
Four-piston aluminium monobloc
brake calipers are fit ted front and
rear. Offering excellent rigidit y,
they are compact and save on
weight. Their superior responsive -
ness, for fast and sensitive
braking, sets them apart. A brake
booster provides assistance,
reducing pedal effort whilst main -
taining a powerful braking effect.
A special ventilation system,
whereby the entire wheel brake
is supplied with cooling air
by openings in the front end and
special channelling systems,
increases the stabilit y of
the brakes during heav y use. The front axle of the Cayman

and Cayman S features internally
vented brake discs with a diameter
of 318 mm. 299 mm brake
discs are fit ted to the rear axle.
The result is outstanding braking
performance. The rear brake discs
of the Cayman S are 4 mm thicker
than those of the Cayman, which
increases stabilit y under load
even further. To distinguish them
visually, the brake calipers on the
Cayman have a black anodised
finish while those on the Cayman S
are painted red.
For reduced weight, optimum
braking in the wet and improved
cooling, the brake discs on
both models are cross- drilled.
For the Cayman S, the Porsche
Ceramic Composite Brake (PCCB)
is available as an option.
