Porsche Doppelkupplung (PDK,
p. 48) is available as an option.
The key elements of PDK are its
seven gears, t wo half gearboxes
and t wo clutches. It features both
manual and automatic modes.
Gears are changed using the gear
selector for PDK, the switches
on the sports steering wheel or
the new optional SportDesign
steering wheel with gearshift
paddles with race track control
logic. The gear change takes
place in a mat ter of milliseconds
without any interruption in the
flow of power. The advantage

over a fully manual transmission
is the considerably faster rate of
acceleration for the same rate of
fuel consumption. The advantage
over a fully automatic transmission
is the perceptible increase in
driving dynamics – with a similar
level of comfort, and a distinct
reduction in fuel consumption.
Two dif ferent characters. One
personalit y. Their drive for power
is impressive, their spirited nature
fascinating. Two sports coupés
that go beyond all conventions.
Two cars that draw their drivers
under their spell, forever.
The concept behind the Cayman
models is the ‘Le Mans Coupé’,

a sports coupé designed in 1953
specifically for this legendary
race and based on the 550
Spyder. Its mid- engine layout is
what made this car special. The
car’s low centre of gravit y gave it
tremendous agilit y and cornering
dynamics. From this one basic
idea came great success, and
with this success our experience
grew. The result? Two sophisticated
sportscars. The Cayman and the
Cayman S.
Their uncompromising perform -
ance is generated by t wo engine
developments, which stand out
above all for their light weight
construction, power output
and ef ficiency. The Cayman has
a 2.9 -litre flat-six engine with a
power output of 195 kW (265 hp).
Even more impressive are the per -
formance values of the Cayman S
with direct fuel injection (DFI, p. 34).
The fuel/air mixture is prepared

entirely in the combustion chamber
af ter having been metered and
injected directly, with millisecond
precision. This means even more
power and torque. To express
this in figures, its 3.4-litre flat-
six engine unleashes a might y
235 kW (320 hp). Depending on
the model, it has been possible
to reduce fuel consumption by
up to 15 % and CO
2 emissions by
up to 16 %.
In either model, this tremendous
power is delivered to the road
by a precision six-speed manual
gearbox.
The primary target group:
your central nervous system.
The Cayman models.
Cayman | The concept
Cayman models: fuel consumption in l/100 km (mpg) urban 14.1 (20.0) –13.6 (20.8) ·

6,000 rpm. From a standing start,
the Cayman accelerates to 62 mph
(100 km/ h) in 5.8 seconds. With the
optional Porsche Doppel
kupplung
(PDK), this sprint takes just
5.7 seconds. Top speed is 165 mph
(265 km/ h) in conjunction with the
manual gearbox. Equally impressive,
however, is the 10 % reduction in with 5-inch display. An integrated
six- disc CD autochanger is
available as an option.
The Cayman has found its way.
Its own? Without doubt.
The Cayman is the driving force
behind precisely one at titude:
the absolute conviction to remain
true to oneself. No middle roads.
No compromises. No nonsense.
One of the features that exempli
-
fies this at titude is the mid- engine
layout, which ensures a low centre fuel consumption and the 12
%
reduction in CO2 em issio ns,
depending on the t ype of gearbox.
The power of the engine is deliv -
ered to the road by a precision
six-speed manual gearbox. Fit ted
as standard are 17-inch wheels
with a star-shaped design, which
allows an eye-catching view of
of gravit y and thus a high degree
of agilit y and an extremely sport y
drive. The six-cylinder horizontally
opposed power unit has a capacit y
of 2.9 litres. The engine delivers a
power output of 195 kW
(265 hp)
at an engine speed of 7,200 rpm.
A maximum torque of 300 Nm
is achieved bet ween 4,400 and the powerful brake system. And
the interior? The overall impression
is simply one of high qualit y. For
instance, the rims of all available
steering wheels are covered in
smooth -finish leather. The centre
console, finished in traditional
black, is equipped as standard
with the CDR-30 audio system
You should never doubt your own principles.

A sports exhaust system – for

each of the Cayman models.
Ignition system.
The ignition system is designed
for static high -voltage distribution.
Individual ignition coils on each
of the spark plugs ensure perfect
ignition every time. The individual
ignition coils are controlled
directly by the engine electronics.
Servicing.
It is a good idea to have your
vehicle serviced regularly, but it
makes just as much sense to keep
the time bet ween maintenance
services as long as possible. Why?
Because a Porsche belongs on
the road, and not in the workshop.
The alternator, power-steering
pump and the air- conditioning
compressor are all driven by a
Exhaust system.
The exhaust system – with t win
tailpipes on the Cayman S – is
made of stainless steel. Until it
converges in the connecting tube,
the exhaust gas is channelled
through t wo separate tracts and,
thanks to separate exhaust gas
cleaning systems, the exhaust
gas can flow more freely – for
increased power and torque.

Put simply, we don’t expect to
see your Porsche too often.

Steering.
What use is a perfect suspension

be inconceivable. The solution is

as much precision and immediacy
as the chassis itself and, thanks to
the power assistance, steering
Wheels.
The Cayman is fit ted with
17-inch wheels as standard. The
star-shaped design expresses
sheer sportiness and allows
an eye- catching view of the brake
calipers. The Cayman S is fit ted
with large, 18-inch wheels as
standard and the turbine-like
arrangement of the spokes gives
the car an extremely powerful
look. 19 -inch wheels are available
for both models on request.
All available wheels are equipped

level. Around the straight ahead
position, such as during motorway
driving, the ratio is less direct

The greater the steering angle,

the more direct the steering ratio.

through tight bends and when
parking and provides a high

ously monitor the speed, lateral
acceleration and steering lock
and, from these variables,
calculate the course of the bend.
This determines the angle of the
dynamic cornering lights, with the
lights able to swivel towards the
inside of the bend up to a limit of
15 degrees, even with the main
beam switched on.
Active safety.
Active safet y is a topic that
Porsche actively supports. With
generous safet y margins, even
the suspension tuning makes a
decisive contribution. Optimum
acceleration enables rapid
overtaking and optimum braking
minimises stopping distances.
Safe contact with the road is
provided not only by the wheel/
t yre combination but also by the auto - deploying bi-plane rear
spoiler and aerodynamic front end.
Another important standard
safet y feature is Porsche Stabilit y
Management (PSM, p. 72).

slogan that t ypifies the headlights
