Brakes.
Outstanding acceleration figures are one
way to express performance. We focus not
only on the positive, but also the negative
values of acceleration. This is how Porsche
has traditionally succeeded in setting
standards for deceleration and stability.
The new Cayman models are equipped
with four-piston aluminium monobloc fixed
brake calipers. This design means that,
not only are the brakes extremely resistant
to deformation, they are light weight for
a particularly fast and sensitive braking
response.
A new generation of brake caliper at the
front axle, combined with enlarged brake
pads and the newly developed brake
booster, has managed to improve braking
and component stability even during con -
tinuous use. In addition, brake cooling is
optimised by the newly developed brake
ventilation system featuring a modified air
spoiler at the front and rear axles.
The enhanced dynamics of the Cayman
and Cayman S also demand appropriate
brake discs. All Cayman brake discs are
internally vented and cross-drilled for
improved braking in wet conditions. With
a diameter of 330 mm, the front brake
discs of the Cayman S are 15 mm larger
than those of the Cayman. The diameter
of the rear brake discs is 299 mm on
both models. The brake calipers on the
Cayman and Cayman S are finished in
black and red, respectively.
Porsche Ceramic Composite Brake
(PCCB).
From the start, Porsche has been synony -
mous with motorsport. Ever since 1948,
when we found our identit y on the race -
track, we have taken the experience we
have gained and applied it to the road.
The optional Porsche Ceramic Composite
Brake (PCCB) is a fine example. This brake
system has already had to cope with the
harshest requirements of motor racing
and is fit ted in cars that compete in
demanding events such as the Porsche

Mobil 1 Supercup.
The cross-drilled PCCB ceramic brake
discs for the new Cayman models have

a diameter of 350 mm front and rear
for even more formidable braking perfor -
mance.
The use of six-piston aluminium monobloc
fixed brake calipers on the front axle and
four-piston units at the rear – all finished
in yellow – ensures extremely high brake
forces which, crucially, are exceptionally
consistent.
PCCB enables shorter braking distances
even in the toughest road and race condi -
tions. Excellent fade resistance ensures
greater balance when slowing from race -
track speeds.

Another key advantage of PCCB is the
extremely low weight of the ceramic brake
discs, which are approximately 50 % light-
er than standard discs of a similar design
and size. As well as enhancing perfor -
mance and fuel economy, this represents a major reduction in unsprung and rotat
-
ing masses. The consequence of this is
bet ter road holding and increased com -
fort, particularly on uneven roads, as well
as greater agility and improved handling. Please note that circuit racing, track day
use and other forms of performance driv
-
ing can significantly reduce the service
life of even the most durable pads and
discs. As with conventional high-perfor -
mance braking systems, we recommend that all brake components be profession
-
ally inspected and replaced where neces -
sary after each track event.
e lectric parking brake.
The electric parking brake, which can be
activated and deactivated manually, is
released automatically as you pull away
with your seat belt fastened. A hill hold
function is integrated as standard for the
manual gearbox and for PDK. It assists
you in making a comfortable, smooth
and roll-free start on an incline. Whenever
you come to halt on an incline, this is
detected automatically and the braking
effect of the electric parking brake is

supplemented by application of the wheel
brakes. As long as a gear remains en -
gaged, the brake pressure is maintained
at all four wheels. To pull away, simply
apply throt tle. As soon as sufficient
starting torque is available, the brake
is
released and the vehicle moves off.

It ’s always worth exploring your own
direction, even if you never know exactly
where this will lead. For this reason, it
pays to have an ingenious safet y concept
on board that employs components that
are just as performance-oriented as the
drivetrain.
In the case of the new Cayman models,
this concept involves an innovative body -
work construction, the stiffness of which
has been purposefully optimised despite
an achieved weight-saving of up to 30 kg
compared with the previous model – a
combination that delivers increased stabi -
lit y and agilit y. It includes an interior that
provides reliable protection in the event of
an accident. It uses a chassis and brakes
that have been specifically matched to
the power output that the new Cayman
models are able to develop. And it is
enhanced by intelligent control systems,
such as Porsche Stabilit y Management
(PSM), which intervene when you reach

the limits of sport y performance.
Some things are indispensable for a broad
view – including a clever lighting concept
with powerful headlights and, of course,
driver assistance systems designed to
give you the right information at the right
time so that you can devote all your at ten -
tion to the next corner.
engineered body design.
The bodyshell of the new Cayman models
is based on an intelligent light weight
principle involving the composite construc -
tion of aluminium and steel. The use of
dissimilar but precisely combined compo -
nents makes it possible to utilise specific
material properties exactly where they
are needed. Not only does this provide a
high degree of safet y for the driver, it
also offers a considerable weight saving
compared with the bodyshell of the prev -
i
ous model. This is why the doors, luggage
compartment lid and rear hatch are made

entirely of lightweight aluminium. Alumi -
nium accounts for around 44 % of the

entire bodyshell. The crumple zones in the front and rear
aprons feature integral light-alloy bumpers,
while impact absorbers offer additional
safet y. For the protection of occupants,
energy-absorbing padding is used selec
-
tively in important areas within the passen -
ger cell.

Cruise control.
Cruise control is available as an option for
the new Cayman models. This automatic
speed controller for the 30 to 240 km/ h
(18–149 mph) speed range is operated
by a switch on a separate control stalk on
the steering
column. The advantages
are clear. Not only can cruise control be
used as a
means of staying within the
speed limit, it also helps you to save fuel
by maintaining
a constant speed.
adaptive cruise control including
Porsche a ctive Safe (P aS).
Also available as an option is the en -
hanced version of cruise control, which
regulates the speed of your vehicle in
line with the speed of the vehicle in
front. A radar sensor inside the front
centre air intake scans the road ahead
up to a distance of 200 m. Imagine
you’ve selected a cruising speed but
have begun to gain on the vehicle in

front because it is driving more slowly –
this is detected by the radar sensor.
The system now reduces the speed of
your vehicle by restricting throt tle or by
gently applying the brakes until your
chosen distance from the vehicle in front
is maintained. If the vehicle ahead slows
further, adaptive cruise control will decel-
erate your vehicle accordingly – even
down to a halt.
For increased safet y, the system also
readies the brakes whenever it detects
that the distance from the vehicle is
decreasing. However, the driver should
be prepared to intervene manually if
heavier braking is required.
As soon as the road ahead clears, your
vehicle will accelerate back up to the
cruising speed originally set. Porsche
Active Safe (PAS) issues an audible and a
visual warning if the system detects that
your vehicle is approaching the vehicle in
front too quickly. This is accompanied by
a brief application of brake force and,
where necessary, the initiation of targeted
braking. During this process, any braking
by the driver is boosted to achieve the
maximum braking force that the system

is able to provide.
Park assist.
Optional Park Assist is activated the mo -
ment you select reverse gear. An audible
signal gives a warning if you reverse too
close to an obstacle.
An enhanced version of Park Assist pro -
vides monitoring of the area to the front
of the vehicle. Ultrasonic sensors are
neatly integrated in the front and rear

aprons. The audible alert is supplemented
by a visual warning in the central display
screen of the CDR audio system or op -
tional PCM showing a graphical represen -
tation of the vehicle from overhead.
‘ w elcome h ome’ lighting.
The ‘Welcome Home’ lighting function
automatically switches on the LED day -
time running lights for a user-defined
period whenever the vehicle is opened

or closed using the key remote.
a nti-theft protection.
The new Cayman models are equipped as
standard with an immobiliser with in-key
transponder. In addition, the Cayman S has
an alarm system with contact-sensitive
exterior protection. A radar-based interior
surveillance system is available on request.
For the Cayman, a combined alarm and
radar-based interior surveillance system is
available as an option.
Porsche Vehicle Tracking System
(PV TS).
This optional preparation enables future
installation of the Porsche Vehicle Tracking
System (PV TS) from Porsche Tequipment.
PV TS makes it possible to locate a stolen
vehicle across most European countries.
The preparation package includes a spe -
cial wiring loom and a tilt sensor for the
alarm system.
