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
(dual-tube on the Cayman S) adds the
powerful finishing touch.
Compared with the previous model, the
wheelbase of the new Cayman has been
extended by 60 mm, the wheels are larger
Retracted, the spoiler separation edge
of the rear wing makes a seamless transi -
tion to the LED taillights. The integrated
direction indicators are narrow and in
line with the wing. The rear apron with
centrally framed stainless-steel tailpipe and the silhouet te is sleeker. The result is
a more dynamic effect on the eye –
and on the road. The side windows are

narrow. If you wish, you can highlight their
contours with the optional trim strips
in a high-gloss finish. The forward-shifted windscreen coupled with the roofline that
extends far into the rear accentuate the
taut appearance of the exterior design.
The exterior mirrors are mounted directly
on the doors for impressive aerodynamics
and low wind noise. Air intake channels,
wheel arches and the roof are clearly

accentuated. The design of the doors gives
emphasis to the Cayman profile and the dynamic contouring improves airflow

to the side air intakes for the purpose
of cooling and supplying oxygen to this
athlete’s beating heart: the boxer engine.
Where the new Cayman models want
to go is clear at first glance. Every line
and every technical detail is focused

in one direction: forwards. Every aspect
tells a story – of character and perfor -
mance.

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.
As a mat ter of principle, out of passion
and in anticipation of the corner ahead.

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.

tion (DFI) as well as efficiency-enhancing
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.

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.

2 emissions and efficiency class, please refer to page 131.

VarioCam Plus.
VarioCam Plus is a two-in-one engine
concept for adjusting the intake cam-
shafts and switching the lift of the intake
valves.
The system first dif ferentiates bet ween
driver inputs that typify normal, everyday
driving and those inputs that demand
maximum performance. The electronic
engine management system then imper -
ceptibly adapts valve operation to
the prevailing conditions. This results
in instant acceleration and extremely

smooth running.
In short, VarioCam Plus provides excellent
acceleration power with comparatively
low fuel consumption.
Integrated dry-sump lubrication.
Integrated dr y-sump lubrication ensures
a reliable supply of oil even when a
sport y driving st yle is adopted and the
vehicle is experiencing powerful lateral

acceleration. It also has additional cool -
ing functions.
The oil tank is located in the engine,
thereby eliminating the need for an exter -
nal oil tank and saving space and weight.
For fuel consumption, CO
2 emissions and efficiency class, please refer to page 131.
To reduce power losses and increase
ef ficiency, an electronically controlled oil
pump supplies the lubricating points
inside the engine as and when required.
It optimises the supply of oil, improves
fuel economy and thereby reduces emis -
sion levels.
