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

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

selection of alternative wheels,
such as the 19 -inch 911 Turbo II
wheel, is featured on page 117.

The optional Tyre Pressure
Monitoring (TPM) sends warnings
to the on -board computer’s
display screen in the event of low

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

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.

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.

it is automatically reactivated for
your safet y if either of the front
wheels (in ‘Sport ’ mode, both
of the front wheels) requires ABS
assistance. ABD remains perma -
nently active. Two additional
functions of PSM increase safet y
even further: precharging of the
brake system, and brake assist.
If you suddenly release the accel -
erator pedal, PSM automatically
readies the braking system. With
the braking system having been
precharged, the brake pads are
already in light contact with the
brake discs. Maximum braking
power is therefore achieved much the car. The forces exerted in a
frontal collision are transmit ted
into the side structure along a
higher load path (4), which improves
the deformation characteristics
of the passenger cell even further.
Porsche Stability Management
(PSM).
PSM, which comes as standard, is
an automatic control system that
stabilises the vehicle at the limits
of dynamic driving performance.
Sensors continuously monitor
driving direction, speed, yaw veloc-
it y and lateral acceleration. Using
this information, PSM computes the
actual direction of motion. If this
direction deviates from the desired
course, PSM initiates braking
interventions targeted at individual
wheels in order to stabilise the
vehicle.
sooner. When sudden braking is
detected, the brake assist function
applies maximum brake pressure
to all four wheels.
Passive safety:
engineered design.
The system of longitudinal and
transverse members at the front
of the vehicle (1) distributes the
Under acceleration on wet or
low-grip road surfaces, PSM
improves traction using the ABD
(automatic brake differential)
and ASR (anti-slip regulation)
functions, giving an agile
response. When ‘Sport ’ mode is
selected on the optional Sport
Chrono Packages (p. 62), the PSM
intervention threshold is raised to
enable greater driver involvement
– particularly at speeds of up to
approximately 70 km/ h (45 mph).
The integrated ABS can further
reduce the braking distance.
For an even sportier drive, PSM
can be deactivated. However, forces exerted onto the bodyshell
in the event of an impact and

minimises deformation of the
passenger cell. Our patented

body work structure with a rigid
bulkhead cross member (2) made
of ultra high-strength steel absorbs
the forces introduced into the
system of longitudinal members
which prevents deformation of the
foot well. The reinforced doors (3)
contribute to the overall rigidit y of

In an era of intensif ying debate
about global climate change and
CO
2 emissions, every automotive
manufacturer is asking itself
what it has to of fer in terms
of environmental protection. Our
answer has long been the same:
maximum ef ficiency.
Over the last 15 years, Porsche
has managed to reduce the
fuel consumption of its vehicles
by an average of 1.7 % each year.
Improvements in fuel economy
also have a beneficial impact
on CO
2 emissions. This has been
achieved through an ef ficient
drive concept (DFI), light weight
construction, optimum aerody -
namics and low rolling resistance.
The goal? Pure performance – but
not at the expense of the environ -
ment. A goal achieved by the
Cayman models.
Exhaust emission control.
Both engines comply with the Euro
5 emission standard
in Europe and
LEV II/ ULEV in
the USA. Vehicles
manufactured by Porsche demon-
strate that even
high -performance
sportscars can achieve moderate
em issio n
values in their respective
category. In short, the Cayman
is not only sport y, it is also clean.
This at tribute is achieved by
means of a t wo -stage cascade-
t ype cataly tic converter
which comprises t wo monolith
substrates on each of the t win
exhaust tracts. These specially
coated substrates contain
ultra-fine honeycomb channels in
which pollutants are converted
