There are some laws that we simply
cannot avoid. The laws of physics, for
example. That ’s not to say that we have
to accept them. Of course, we could
refuse to respect them and we could
choose to ignore them. On the other
hand, we could study them, test them
and redefine their limits. This is exactly
what we did and, in doing so, we discov -
ered a new law: the code of the curve.
The code is purposefully enacted by
a sports car that eschews the more conventional principles of automobile
construction and interprets passion for
the sports car in an innovative way:
with a compelling mid-engine concept,

which provides a low centre of gravit y
for a balanced and precise driving
experience
and, like any Porsche, offers
im
proved performance at the same time
as enhanced efficiency. This concept
is combined with innovative technologies
and an intelligent lightweight construction
for the optimum
power-to-weight ratio.
The chassis focuses
on delivering power to the road and the
most exhilarating
place of all – the corner.
The look is
unmistakable, with every line and every
edge striving for
wards. The ergonomic
interior is complemented by a roomy
luggage space. After all, sport y driving
is an entirely practical concept.

It ’s always worth taking the direct route:
from stimulus to response, from resting
pulse to pounding heart, from impulse to
endorphin rush – not least when the dis-
tance to travel is less than half a metre.
The new Cayman is equipped with a com -
pletely newly developed 2.7- litre boxer
engine and the Cayman S is driven by a

3.4-litre variant, both of which are tuned
for sport y driving. Accelerator pedal in -
puts are translated directly into propul -
sion. Maximum torque is available over a
broad engine speed range. Both engines feature direct fuel injection
(DFI) and VarioCam Plus. Power is trans
-
mit ted to the wheels by a smooth
6-speed manual gearbox or the optional

7-speed Porsche Doppelkupplung (PDK).
Exemplary efficiency is achieved by means
of sophisticated technologies. As stand ard,
these include the auto start/stop function,
electromechanical power steering, elec -
trical system recuperation and intelligent
thermal management. The result, depend -
ing on the equipment variant, is a 16 %
reduction in CO2 emissions compared with
the previous model.

e ngineering.
Thanks to our principles of intelligent light -
weight construction, we have succeeded
in making the body stiffer and simultan-
eously lighter. The chassis has been com -
pletely revised. For enhanced dynamic per -
formance and increased driving stability
when the car is pushed to the limit, both
models are equipped with Porsche Stability
Management (PSM). Enhanced Porsche
Active Suspension Management (PASM)
is available as an option and includes a
ride height reduction of 10 mm. Porsche
Torque Vectoring (PT V) with rear differen -
tial lock for increased agilit y and traction
in corners is also available on request.
For fuel consumption, CO
2 emissions and efficiency class, please refer to page 131.
The optional Sport Chrono Package makes
the response and handling characteristics
of the new Cayman even sportier. For the
first time, the package now also includes
dynamic transmission mounts, which make
a perceptible contribution to handling
stabi l ity in fast corners whilst ensuring
a high degree of ride comfort.
Several years of development work and
countless draf ts later, our engineers have
realised their goal: the direct link bet ween
action and reaction. Experience the result
in the new Cayman, and let your pulse
rate be the measure of success.

Inner strength, the will to advance and a
clear point of view. These are important
prerequisites for the creation of any
sports car, and we also found them to be
precisely the right requirements for this
drivetrain.
That is why the new Cayman models are
equipped with a compact, mid-mounted
boxer engine positioned no further than
30 cm behind the driver. This unorthodox
approach has crucial strengths. A substan-
tial amount of vehicle weight is concen-
trated close to the middle of the vehicle.
The centre of gravit y is low and central and weight is distributed uniformly

bet ween the front and rear axles. The
tangible effect for you is well-balanced
handling and excellent agility, particularly
in corners.
Inner values are defined by high power
plus reduced fuel consumption and emis -
sion figures compared with the previous
model. We call it Intelligent Performance,
a philosophy that applies the engineering
principles of the racetrack to the road.
Both engines are equipped as standard
with VarioCam Plus and direct fuel injec -

tion (DFI) as well as efficiency-enhancing
technologies such as auto start /stop,
electrical system recuperation and
ad

What can you expect from the driving
experience? Direct responses to every
burst of acceleration, dynamic handling
in every corner and the inevitable pain
of separation at the end of every drive.

VarioCam Plus.
VarioCam Plus is a two-in-one engine
concept for adjusting the intake cam-
shafts and switching the lift of the intake
valves.
The system first dif ferentiates bet ween
driver inputs that typify normal, everyday
driving and those inputs that demand
maximum performance. The electronic
engine management system then imper -
ceptibly adapts valve operation to
the prevailing conditions. This results
in instant acceleration and extremely

smooth running.
In short, VarioCam Plus provides excellent
acceleration power with comparatively
low fuel consumption.
Integrated dry-sump lubrication.
Integrated dr y-sump lubrication ensures
a reliable supply of oil even when a
sport y driving st yle is adopted and the
vehicle is experiencing powerful lateral

acceleration. It also has additional cool -
ing functions.
The oil tank is located in the engine,
thereby eliminating the need for an exter -
nal oil tank and saving space and weight.
For fuel consumption, CO
2 emissions and efficiency class, please refer to page 131.
To reduce power losses and increase
ef ficiency, an electronically controlled oil
pump supplies the lubricating points
inside the engine as and when required.
It optimises the supply of oil, improves
fuel economy and thereby reduces emis -
sion levels.

Strong relationships need sincerity,
common goals and the abilit y to over-
come difficult situations in unison.
The chassis of the new Cayman models
develops a strong bond with the road. It
is specifically matched to the high power
output of the respective engine. A xle
components are made predominantly of

aluminium, which helps to keep the weight
of the vehicle and its unsprung masses
low. The results are impressive driving
dynamics with practically zero pitch and
roll, high levels of comfort and safet y and
lower fuel consumption. The track of the new Cayman models has
been widened and the wheelbase has

been extended by 60 mm compared with
that of the previous model. This improves
stabilit y. The new independent suspension
features light weight spring-strut axles
with longitudinal and transverse links. The
cross member at the front axle has been
refined for optimum stiffness and robust -
ness. How does this benefit you? Greater
directional stability, sharper steering preci -
sion and sportier handling.
Porsche active Suspension management
(PaSm ).
Optional PASM, the electronic damping
control system, actively and continuously
regulates the damping force for each
wheel according to the road conditions
and driving st yle. In addition, the suspen -
sion is 10 mm lower than that of the
st a n d a rd s e t u p .
The system is always active in the back-
ground, ready to assist you automatically
without you having to switch it on. Never -
theless, t wo modes are available at the
push of a but ton so that you can adapt
handling to suit your preferred driving
st yle: ‘Normal’ which is a blend of perfor-
mance and comfort, and ‘Sport ’ where
the setup is much firmer. Depending on
the mode selected, therefore, PASM can
be sportier and more comfortable than
the standard chassis. The PASM control
unit evaluates the driving conditions and modifies the damping force on each of
the wheels optimally in accordance with
the selected mode.
Sensors record all wheel and body move
-
ments. This enables intelligent adaptation
of damper stiffness for the selected
mode, optimising contact between each
individual t yre and the road for even less
roll and pitch.

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.
