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.
The new Cayman models. Built according
to our own st yle and with respect for the
code of the curve.

Design
e xterior.
Character, profile and a clear point of view.
These values have been encoded in the
Cayman genes since the very beginning.
Aesthetically, they have evolved to find
a precisely st yled expression defined by
sculpted lines and edges, sleek wheel arches, short overhangs, taut proportions
and a classic silhouet te.
The front is dominated by the prominent
wings for which
Porsche is renowned,
and features rest yled headlights inspired
by the Porsche racing heritage of the 1960s and 1970s. With its large and

dynamic air intakes, the front end rein -
forces the car’s powerful demeanor.
For the Cayman slats in the exterior
colour of the vehicle lend structure
for the Cayman S however, the black
air intakes and front spoiler, in the same colour as the exterior, accentuate
the car’s sport y nature.
The circular
front light units integrated in
the air
intakes are a classic feature of
Cayman
styling and incorporate LED daytime
running lights and position lights for
active safety. Precise edges stretch backwards along
the roof to the rear. In conjunction with
the wide track, the effect is a sculpted

and honed physique. Imposing wings

lend prominence to the wheels. The wide
brake light is an integral feature of the
large rear screen.
The rear wing is more than a stunning
eye-catcher. It deploys automatically
at
120 km/ h (74 mph) and its effective
aerodynamic surface area has been
enlarged, reducing lift
to improve contact
with the road and heighten driving pleas -
ure
at the limits of sport y performance.
Forward thinking.

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.
Six cylinders. Four heart chambers.
Just 30 cm apart.

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.

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.

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.

technologies such as auto start /stop,

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.

Thermal management.
The intelligent thermal management
system in the Cayman models regulates
the temperature in the engine and gear -
box
to reduce friction losses that occur
during the warm-up phase.

Thanks to the purposeful control of heat
flow and on-demand, gradual activation
of the various cooling circuits, the engine
and gearbox warm up to normal operat -
ing temperature more rapidly. The result -
ing reduction in friction also reduces fuel
consumption and CO
2 emissions. During
sporty driving, thermal management also
acts to reduce temperatures so as to
maintain a high degree of performance. Our cross-flow cooling system, as used

in motorsport, supplies each engine cylin -
der uniformly with coolant, which protects
all valves against thermal overload and,
therefore, premature wear. This improves
combustion and keeps emissions, fuel con -
sumption and noise comparatively low.
exhaust system.
In the new Cayman models, each cylinder
bank has its own stainless-steel exhaust
tract. Downstream of their respective rear
silencer, the tracts converge into a con -
necting tube and a single (Cayman) or t win
(Cayman S) tailpipe. The stereo Lambda
control circuitr y

controls and monitors each cylinder bank
separately. For each
exhaust tract, four
corresponding oxygen sensors regulate
the composition of the exhaust gas and
monitor the performance of the catalytic
converters. The separate
tracts enable
the exhaust gas to flow more
f re e l y. T h e
resulting reduction in pressure loss has
a positive impact on power output, torque
and the unmistakable engine sound.
Available as an option for the new Cayman
models is the sports exhaust system*
including sports tailpipe. It produces an

even more resonant Porsche sound.

e ngine management.
The electronic engine management
system ensures optimum perfect engine
performance at all times. It regulates all
engine-related functions and assemblies.
The results are optimum power output
and torque with comparatively low fuel
consumption and emissions – whatever
the driving st yle.
One example is the cylinder-specific knock
control. Since engine cylinders never all
work under exactly the same conditions,
the knock control function monitors each one separately. The ignition point is shift
-
ed individually, as and when necessary,
so as to protect the cylinders and pistons
at high engine speeds and loads. For
compliance with EU standards, the on-
board diagnostics detect any faults and
defects that may occur in the exhaust
and fuel systems and then display them
on the on-board computer. This also
helps to avoid increased pollutant emis
-
sions and unnecessary fuel consumption.
a uto start/stop function.
The auto start/stop function, which is in -
tegrated as standard in the new Cayman
models, switches off the engine when
you stop, select neutral and release
the clutch pedal. In cars with Porsche
Doppelkupplung (PDK), it is simply a
case of applying and holding the brake.
All audio and communication systems
remain switched on. The engine will

restart as soon as you operate the clutch
or, in cars with PDK, release the brake.
This fuel-saving innovation is designed

primarily for use in urban traffic. The auto start /stop function can be deac
-
tivated and reactivated using a separate
but ton on the centre console. The func -
tion is deactivated automatically under
particular circumstances, e.g. in the
event of extreme outside temperatures,
activation of the SPORT but ton or low

bat tery charge.

SP or T button.
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.
