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.

Porsche Stability management (PSm).
Enhanced Porsche Stability Management
(PSM) is fit ted as standard. This system
automatically maintains stability and trac -
tion even at the limits of dynamic driving
performance. Sensors continuously moni -
tor the direction, speed, yaw velocit y and
lateral acceleration of the car. Using this
information, PSM is able 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 in order to restore
stability.
Under acceleration on wet or low-grip road
surfaces, PSM improves traction – as well
as agilit y, control and safet y – using the
automatic brake differential (ABD) and
antislip regulation (ASR). Integrated ABS

is designed to minimise braking distances.
If you prefer an ever sportier drive, PSM
can be switched off. For your safet y,
however, PSM remains set to intervene if
the vehicle is braked and ABS assistance
is required.
Also included with PSM are engine drag
torque control (EDC), precharging of the
brake system and brake assist. If you
suddenly release the accelerator pedal
,
PSM automatically prepares for your next
action: the braking system is precharged
so that the brake pads are already in light

contact with the brake discs. Maximum
braking power is therefore achieved
much sooner. Brake assist detects a
panic braking situation and generates

the brake pressure required for maximum
deceleration.
PSM increases driving stabilit y and safet y
as well as the agilit y you have come to
expect from a Porsche.

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.

a irbags.
To protect the driver and passenger,
the new Cayman models are equipped
as standard with full -size airbags, which
are inflated in t wo stages depending on
the severit y and t ype of accident (e.g. frontal or offset frontal). In less serious
accidents, the airbags are only partially
inflated, thereby minimising discomfort

to the occupants. In addition to the central airbag control
unit on the transmission tunnel, a pair

of impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated far sooner and
with considerably greater accuracy.

manufacturers are among those asking
themselves how they can contribute to

environmental protection. Our answer
has long been the same: Intelligent Per -
formance – a combination of high power
output and high efficiency.
In recent years, Porsche has managed to
reduce fuel consumption across all model
ranges by a double-digit percentage com -
pared with the respective previous model,
even though performance has been in -
creased in every generation. This is made
possible by an ef ficient drive concept,
including direct fuel injection (DFI) and
VarioCam Plus, a lightweight construc -
tion, optimised aerodynamics and low
rolling resistance.
The environmental management team
at the Porsche Development Centre in
Weissach demonstrates a high level of
environmental responsibility. Here, tech -
nological developments are carried out
with environmental protection in mind.
The goal is to enhance performance –
but preferably not at the expense of the
environment. We achieve this goal with

by the new Cayman.

environment.
e mission control.
Vehicles manufactured by Porsche dem-
onstrate that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emission
val
ues in their respective category.
This is accomplished by the use of fuel-
ef ficient technologies such as auto start /
stop, thermal management, electrical
system recuperation, direct fuel injection,
VarioCam Plus and, in conjunction with
optional PDK, coasting mode.
The newly developed cataly tic converters
also provide ef ficient emission control,
while the stereo Lambda control circuitr y
manages and monitors each cylinder
bank separately. For each exhaust tract,
oxygen sensors, together with the engine
electronics and injectors, regulate the
composition of the exhaust gas, while
another Lambda sensor on each cylinder
bank monitors pollutant conversion in
the respective cataly tic converter.

Environment
Fuel economy and recycling.
Intelligent lightweight construction is, and
always has been, a fundamental aspect of
the Porsche philosophy – for both techni -
cal and ecological reasons. This combina -
tion forms the basis for achieving low fuel
consumption values in conjunction with
high performance. On the technical side,
various components are made with a high
proportion of alu minium, magnesium, plas -
tics and super- high -strength sheet steel.
The materials used have been selected
for their abilit y to withstand load, yet they
are considerably lighter than conventional
steel. As a result, the bodyshell of the new
Cayman models has a light alloy content
of approximately 44 %.
On the ecological side, all materials used
are meticulously selected. We use only state-of-the-art components, with priority
given to products manufactured in a sus
-
tainable manner where possible. All syn -
thetic components are easily recyclable
and each material is labelled to facilitate
its separation for recycling. The reduction
in the number of plastic variants helps to
ensure more efficient recycling. Recycled
plastics are used where they meet our
exacting technical requirements.
In short, the new Cayman is around 95 %
recoverable.
In addition, Porsche uses a high proportion
of environmentally friendly water-based
paints. For us, environmental protection
does not begin with the vehicle manufac -
turing process. It starts at the planning
and development stage.
Fuel.
The new Cayman models are designed to
operate on fuels with an ethanol content of
up to 10 %. Ethanol has a positive impact
on the CO2 balance since the plants grown
for the production of this biofuel also
absorb CO
2 from the atmosphere. The
release of hydrocarbons from the fuel

system has been minimised thanks to the
active carbon filter and the multilayered
material from which the fuel tank is made.
Servicing.
Long service intervals offer clear advan -
tages. For you, they reduce costs and
save time. For the environment, they assist
in the sparing use of consumables and
replacement parts. For full details of ser -
vice intervals, please refer to the separate
price list.
