With the SPORT but ton selected, the full
advantages of the new version of PDK
are brought into play: a more immediate
response to throt tle inputs, relatively
short shift times and swift throt tle-blip
downshifts on overrun, such as during
braking into a corner, and always accom -
panied by an emotive engine sound.
With the optional Sport Chrono Package,
PDK is enhanced by ‘Launch Control’
and the ‘motorsport-derived gearshift
strategy’ for even faster and firmer gear
changes and best possible per formance,
thanks to a boost in torque during up -
shift phases. Overrun downshifts provide
extremely sport y braking and accelera -
tion for added excitement.
Coasting.
Efficiency is another area in which the
performance of the new Cayman models
has been further improved. The coasting
function available with Porsche Doppel-
kupplung (PDK) enables you to save even
more fuel where the situation allows.
The engine is decoupled from the trans -
mission to prevent deceleration caused
by engine braking. In this way, optimum
use is made of the vehicle’s momentum,
allowing it to coast for longer distances.
For example, you may want to slow down
from 100 to 80 km/ h (70 to 50 mph) in
anticipation
of the change of speed limit
ahead. As you ease off the accelerator
pedal, PDK deselects the current gear
automatically and you begin to coast in
neutral with minimal input required on
your part until
you have reached your desired speed.
As soon as you operate
the accelerator
or brake pedal, PDK
re-engages the appropriate gear within
fractions of a second. The process
is smooth and seamless, thanks to the
extremely fast
clutch.
Another way to reduce fuel consumption
is to utilise the coasting function on down -
hill gradients that are gentle enough for
you to maintain a constant speed. Efficient
on long journeys, such as on the motor -
way, PDK remains ready to respond as

swiftly and precisely as you would expect.
In short, driving in coasting mode makes
a real impact on fuel consumption without
the need to compromise on comfort or
sporty performance.

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.

In ‘Sport ’ mode, for example, the suspen -
sion is set to a harder damper rating. On
uneven roads, PASM immediately switch -
es to a softer rating, thereby improving
contact bet ween the t yres and the road.
When the road surface improves, PASM
automatically reverts to the original,
harder rating. If ‘Normal’ mode is select -
ed and the driver’s st yle becomes more
assertive, PASM switches to a harder
rating to increase driving stabilit y and
road safety.
Steering.
Our interpretation of efficiency is a sys -
tem that works only when it is needed,
and then does so in a particularly effec -
tive way. Whereas a conventional hydrauli -
cally assisted steering system draws
engine power continuously, the electric
motor of the electromechanical system
in the new Cayman models uses energy
only when you actually steer. As a result,
fuel consumption is reduced and the
absence of hydraulic fluid eliminates the need for servicing the system. These
t wo advantages are also beneficial to
the environment.
A variable steering ratio preserves the
precise and direct steering response
associated with the t ypical Porsche steer-
ing feel. This intelligent system filters
out unwanted shocks from the road and
actively assists steering inputs under
braking on road surfaces with varying

grip.
Available as an option, speed-sensitive
Power steering Plus facilitates manoeu -
vring and parking for even greater driving
comfort.

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.

Porsche Torque Vectoring (PTV).
This optional system for increasing
dynamic performance and stability varies
the distribution of torque to the rear
wheels and includes a mechanically lock -
ing rear differential. When the car is driven assertively into

a corner, moderate brake pressure is
applied to the inside rear wheel. Conse -
quently, an additional rotational pulse
(yaw movement) is induced around the
vehicle’s vertical axis in the direction of the turn. This results in a direct and
sport y steering action as the car enters
the corner.
At low and medium vehicle speeds, PT V
significantly increases agilit y and steering
precision. At high speeds and when

accelerating out of corners, the rear

differential lock ensures greater driving
stabilit y and traction on road surfaces
with varying grip, including the wet and
snow.
The results are remarkable stability,
optimum traction and excellent cornering
dynamics at all speeds, coupled with
precise steering and stable load transfer
characteristics through ever y t wist and
turn of your journey.

Sport Chrono Package.
Better performance would normally be
impossible to achieve without more inten -
sive training. In the new Cayman models,
it comes at the push of a but ton. The
optional Sport Chrono Package provides
simultaneous enhancement for the chas -
sis, engine and transmission – accom -
panied by an even more emotive sound.
In addition to the performance display,
a digital and an analogue stopwatch,

the Sport Chrono Package also includes
dynamic gearbox mounts (p. 64). Another
component is the SPORT PLUS but ton.
When this is pressed, optional Porsche
Active Suspension Management (PASM)
switches to ‘Sport ’ mode for harder
damping and more direct steering and,
therefore, even more intensive road

holding.
The trigger threshold for PSM is raised.
Agilit y is perceptibly enhanced when
braking for corners with PSM, allowing
even sportier braking and exit accelera -
tion. For even greater dexterit y, PSM can
be set to standby while the car is still in
SPORT PLUS mode. For safet y, it is set
to intervene automatically only when ABS
assistance is required.
The throttle-blip function produces even
sportier gearshifts. A managed burst
of throt tle ensures smooth load changes
for increased stabilit y and makes the
gearshift process an even more engaging
experience.
In conjunction with optional PDK, the
Sport Chrono Package comes with t wo
additional functions for a sport y drive
that borders on a motorsport experience. The first is ‘Launch Control’, which is de
-
signed to produce a racing start.
The second function is the ‘motorsport-
derived gearshift strategy’. In this mode,
PDK is designed for very short shift times
and optimum shift points, while torque
boosts during gear changes provide the
maximum acceleration available. Thi
s
involving experience is further enhanced
by overrun downshifts and the throt tle-
blip function for uncompromising driving
pleasure.
An additional display in the steering wheel
and instrument cluster indicates whether
the SPORT or SPORT PLUS but tons
and, with PDK, Launch Control have been
activated. In conjunction with optional
Porsche Communication Management
(PCM), a special display enables you to

view, store and evaluate lap times or other
driving times. It shows the total driving
time, lap distance, lap number and lap
times recorded so far.

Dynamic gearbox mounts.
Dynamic gearbox mounts are a component
of the optionally available Sport Chrono
Package. This electronically controlled
system minimises the oscillations and

vibrations of the entire drivetrain, especial
-
ly the engine, and combines the benefits that otherwise distinguish hard and soft
gearbox mounting arrangements.
A hard gearbox mounting delivers optimum
dynamic performance because it offers a
high degree of handling precision. Soft
gearbox mounts, on the other hand, mini
-
mise oscillations and vibrations. While
comfort is improved on uneven road
surfaces, this comes at the expense of

dynamic performance.
Dynamic gearbox mounts adapt their
stif fness and damping characteristics to changes in driving st yle and road surface
conditions. This has been achieved by
use of a fluid with magnetic properties in
interaction with an electrically generated
field. For the driver, the results are tangi
-
ble. Handling is perceptibly more stable
under load change conditions and in fast corners. Whenever a less assertive

driving st yle is adopted, the dynamic
gearbox mounts automatically sof ten

to enhance comfort.
The result is uncompromisingly sporty
performance in corners – as well as a
high degree of comfort.
The SPORT or SPORT PLUS but ton
enables you to switch the dynamic gear -
box mounts from ‘Normal’ to ‘Sport ’ or
‘Performance’ mode. In conjunction with
optional PCM, the TFT screen in the right-
hand circular instrument enables you to
view the lateral and longitudinal forces
as they act on the vehicle.

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.

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

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.

You aren’t the cosy t ype, but you do
appreciate the value of comfort and

convenience.
The completely rest yled interior of the
new Cayman models will therefore make
you feel right at home. Here, every thing
is focused on one goal: advancing with
a blend of sport and comfort. The driver
is optimally integrated in the vehicle. The
ascending centre console positions the
gear lever close to the steering wheel for
fast, sporty and ergonomic gearshifts. The individual controls are clearly organ
-
ised. All but tons and the functions of the
on-board computer are intuitive to find
and select so that you can devote your
full at tention to the road.
The sport y character of the new Cayman
is further reinforced by the Sports seats –
fit ted as standard and with seat centres in
Alcantara. Materials have been carefully
chosen to ensure exquisite and st ylish
integration in the interior design. The

visible effect is exemplified by the silver-
coloured details on the dashboard and
centre console and by leather appliqués
on selected features, such as the steering
wheel rim, gear lever/selector and door
handle inlays. In the Cayman S, the door
armrests and the storage compartment
lid on the centre console are also finished
in leather as standard.
Nevertheless, there
is scope to refine and
st yle your Cayman
with, for example, the
comprehensive
leather interior package.
