Exploring your own direction takes
unswerving conviction, but that doesn’t
mean you should have to forgo cornering
fun – especially not in the new Cayman.
One good reason is the new mid-mounted
boxer engine. With a displacement of 2.7 litres, this
6-cylinder engine equipped with direct
fuel injection (DFI) and VarioCam Plus
produc
es 202 kW (275 hp) and enables
a top speed of 266 km/ h (165 mph).
With the precisely geared 6-speed
manual gearbox fit ted
as standard, the Cayman accelerates from 0 to 100 km/ h
(0 – 62 mph) in 5.7 seconds. With
the

optional 7-speed Porsche Doppel
kupplung
(PDK) combined with the Sport
Chrono
Package also available on request,
this
time is cut to 5.4 seconds.
The revised front end with air intakes
painted in the same colour as the exterior
is distinctive. Halogen headlights are
fit ted as standard. The 18-inch Cayman
wheels with dual-arm spoke design are

elegantly st yled. The brake system
with
4-piston aluminium monobloc fixed calipers in black is powerful and

reassuring. The sound
from the
central tailpipe in brushed stainless
steel is unmistakable. The new Cayman. Wouldn’t it be boring

if an unswerving conviction always led
you down the straight road?

Cayman S
Those who give their all,
should be given it all back.

The new Cayman S.Having an idea is one thing, thinking it
through to the end is another. Some-
times you have to give your all, and with
the new Cayman S this is exactly what
we did – in every respect and with suc -
cess. Its 3.4-litre flat-six engine with DFI
and VarioCam Plus generates 239 kW
(325 hp). It accelerates from 0 to 100 km/ h
(0–62 mph)
in 5.0 seconds and achieves

a top speed
of 283 km/ h (175 mph).
With PDK and the Sport Chrono
Package, both of which are optional, it
reaches 100 km/ h in just
4.7 s e c o n d s. Improved performance demands capable
components. The chassis of the new

Cayman S is matched specifically to the
high power output of the engine. Even
greater levels of agilit y, traction and con -
trol in corners can be achieved with
Porsche Active Suspension Management
(PASM), Porsche Torque Vectoring (PTV)
with rear differential lock and the dynamic
gearbox mounts of the Sport Chrono
Package – all of which are available from
our list of options. For added safet y, the
front axle is equipped with larger brake
discs to cope with the increased engine
power. The brake calipers are finished
in red. Imposing 19-inch Cayman S light-
alloy wheels with a classic five-spoke
design are fit ted as standard.
On the new Cayman S, Bi-Xenon headlights
are fit ted as standard. The precisely st yled
LED front light units accentuate the front
air intakes finished in black. At the rear,
the twin tailpipe in brushed stainless steel is located in the centre and produces the
typically resonant
Porsche sound.
For the new Cayman S, we gave our all.
As a mat ter of principle, out of passion
and in anticipation of the corner ahead.

resonance intake manifold.
The resonance effect, where the air mass
inside the intake manifold is caused to
oscillate, is used to improve air induction
and, in turn, to optimise the formation
of the fuel/air mixture. In the Cayman S,
the manifold is also equipped with a
switchable resonance valve.
The results are high torque, a uniform
torque curve and high power output.

The sound produced is characteristically
resonant and deep.
Direct fuel injection (DFI).
Direct fuel injection (DFI) is featured as
standard in both Cayman models. Multi-
hole injectors deliver fuel directly into the
combustion chamber with millisecond
precision. The injection pattern has been
optimised for torque, power output, fuel
consumption and emissions. Combustion
is even more effective as a result.
With direct injection, the engine manage -
ment system regulates injection timing
individually for each cylinder as well as
the injection rate for each cylinder bank.
This optimises the combustion process
and therefore fuel economy. Depending on the engine operating con
-
dition, multiple fuel injections take place
so that the cataly tic converter reaches
normal operating temperature sooner
after a cold start and a greater top-end
torque can be achieved.
DFI improves the internal cooling of the
combustion chamber by having the mix -
ture prepared directly in the cylinder. This
allows for a higher compression ratio,
which helps to deliver greater power out -
put at the same time as enhanced engine
efficiency. Injection is regulated by the
electronic engine management system
and emissions are monitored by the
stereo Lambda sensors, thus helping to
protect the environment.

The SPORT but ton on the centre console
is fit ted as standard. When selected,
‘Sport ’ mode is activated to provide a
greater response and enhanced driving
pleasure. The engine reacts even more
directly to the accelerator pedal, the

rev-limiter is adjusted to a harder set ting
and engine dynamics are tuned for per -
formance driving. At the same time, the
auto start /stop function is deactivated
automatically.
With optional Porsche Doppelkupplung
(PDK), the shift points are reconfigured
to offer higher and even sportier rpm bands. Shift times are reduced and gear
-
shifts become firmer and more immedi -
ate, while throttle-blip downshifts are
accompanied by an even more emotive
engine sound. Coasting mode (p. 44) is
deactivated automatically. e lectrical system recuperation.
Another efficiency-enhancing feature of
the new Cayman models is intelligent
electrical system recuperation. The vehi-
cle bat tery is recharged by the generator
predominantly under braking. Thanks
to this selective recharging, when you

request full driving power, the maximum
possible output of the engine can be
directed straight to the road because

the electrical systems are supplied main -
ly by the energy that was stored in the
battery during the braking phase.
Servicing.
In the Cayman models, the generator and
air conditioning system are driven by a
single self-adjusting belt. The drive chains
on the camshafts do not normally require
servicing. With the sole exception of the spark
plugs, the ignition system is also

maintenance-free. In short, longer service
intervals mean longer-lasting driving
pleasure.

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.

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.
