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.

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.

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.

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.

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.
