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.

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.

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.

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.

Brakes.
Outstanding acceleration figures are one
way to express performance. We focus not
only on the positive, but also the negative
values of acceleration. This is how Porsche
has traditionally succeeded in setting
standards for deceleration and stability.
The new Cayman models are equipped
with four-piston aluminium monobloc fixed
brake calipers. This design means that,
not only are the brakes extremely resistant
to deformation, they are light weight for
a particularly fast and sensitive braking
response.
A new generation of brake caliper at the
front axle, combined with enlarged brake
pads and the newly developed brake
booster, has managed to improve braking
and component stability even during con -
tinuous use. In addition, brake cooling is
optimised by the newly developed brake
ventilation system featuring a modified air
spoiler at the front and rear axles.
The enhanced dynamics of the Cayman
and Cayman S also demand appropriate
brake discs. All Cayman brake discs are
internally vented and cross-drilled for
improved braking in wet conditions. With
a diameter of 330 mm, the front brake
discs of the Cayman S are 15 mm larger
than those of the Cayman. The diameter
of the rear brake discs is 299 mm on
both models. The brake calipers on the
Cayman and Cayman S are finished in
black and red, respectively.
Porsche Ceramic Composite Brake
(PCCB).
From the start, Porsche has been synony -
mous with motorsport. Ever since 1948,
when we found our identit y on the race -
track, we have taken the experience we
have gained and applied it to the road.
The optional Porsche Ceramic Composite
Brake (PCCB) is a fine example. This brake
system has already had to cope with the
harshest requirements of motor racing
and is fit ted in cars that compete in
demanding events such as the Porsche

Mobil 1 Supercup.
The cross-drilled PCCB ceramic brake
discs for the new Cayman models have

a diameter of 350 mm front and rear
for even more formidable braking perfor -
mance.
The use of six-piston aluminium monobloc
fixed brake calipers on the front axle and
four-piston units at the rear – all finished
in yellow – ensures extremely high brake
forces which, crucially, are exceptionally
consistent.
PCCB enables shorter braking distances
even in the toughest road and race condi -
tions. Excellent fade resistance ensures
greater balance when slowing from race -
track speeds.

Another key advantage of PCCB is the
extremely low weight of the ceramic brake
discs, which are approximately 50 % light-
er than standard discs of a similar design
and size. As well as enhancing perfor -
mance and fuel economy, this represents a major reduction in unsprung and rotat
-
ing masses. The consequence of this is
bet ter road holding and increased com -
fort, particularly on uneven roads, as well
as greater agility and improved handling. Please note that circuit racing, track day
use and other forms of performance driv
-
ing can significantly reduce the service
life of even the most durable pads and
discs. As with conventional high-perfor -
mance braking systems, we recommend that all brake components be profession
-
ally inspected and replaced where neces -
sary after each track event.
e lectric parking brake.
The electric parking brake, which can be
activated and deactivated manually, is
released automatically as you pull away
with your seat belt fastened. A hill hold
function is integrated as standard for the
manual gearbox and for PDK. It assists
you in making a comfortable, smooth
and roll-free start on an incline. Whenever
you come to halt on an incline, this is
detected automatically and the braking
effect of the electric parking brake is

supplemented by application of the wheel
brakes. As long as a gear remains en -
gaged, the brake pressure is maintained
at all four wheels. To pull away, simply
apply throt tle. As soon as sufficient
starting torque is available, the brake
is
released and the vehicle moves off.

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.
