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.

Six-speed manual gearbox.
The new Cayman models are equipped
as standard with the six-speed manual

gearbox. Gearshifts are smooth, precise
and optimally adapted to the respective
engine map. Shift throws are short and
the gear lever is easy to operate, provid -
ing a truly engaging driving experience.
The upshift indicator located in the central
circular instrument helps you to maximise
fuel efficiency.
The ascending centre console reinforces
the authentic sports car feel. It positions
the gear lever close to the steering wheel,
enabling you to change gear as fast and
as ergonomically as possible.
Porsche Doppelkupplung (PDK).
Of course, you could let us take care of
the gearshift strategy so that you can
devote all your at tention to your cornering
strategy.
Available as an option is the completely
retuned 7-speed Porsche Doppelkupplung
(PDK), featuring both manual and auto -
matic modes. The advantages are percep -
tible. Gear changes take place with no
interruption in the flow of power. Sharper
gearshift programs and significantly short -
er shift times produce faster acceleration
than with the manual gearbox. Fuel econ-
omy and comfort characteristics have also
been optimised. In response to a less
assertive driving st yle, shif t points are

recalculated to make use of the more
comfortable and more economical engine
speed ranges, and coasting mode is acti -
vated where possible (p. 44).
This is how PDK works: PDK is essentially
t wo gearboxes in one, thus requiring t wo
clutches. This double clutch arrangement
provides an alternating, non-positive con -
nection between the two half gearboxes
and the engine by means of t wo separate
input shafts. The flow of power from the
engine is transmit ted through one half
gearbox and one clutch at a time, while

the next gear is preselected in the second
half gearbox. During a gear change, there -
fore, one clutch simply opens and the
other closes at the same time, enabling
gear changes to take place within milli
-
seconds.
PDK has seven forward gears at its
disposal. Gears 1 to 6 have a sports
ratio and top speed is reached in sixth

gear. Seventh gear has a long ratio and
keeps
engine speed low to reduce fuel
con
sumption and improve comfort.

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.
h ow do we nurture our relationship with the driver?
By purposefully strengthening our bond with the road.

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.

lights.
A design is either fascinating or functional.
The front and rear lights of the new
Cayman models can be both. Clear glass
halogen headlights are fit ted on the
Cayman as standard. The Cayman S is
equipped as standard with Bi-Xenon
headlights. In classic Cayman fashion,

the circular front light units with LED
day time running lights and position lights
are integrated in the air intakes. LEDs
provide powerful illumination, respond
extremely rapidly to driver input and
offer improved energy performance

combined with a longer service life. The
taillights also employ LED technology for increased safet y and an unmistakable

appearance – day and night.
