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.

Integrated dry-sump lubrication.
The purpose of integrated dry-sump
lubrication is to guarantee a
reliable oil supply while reducing
engine temperatures, even in
sportily driven cars. The oil reser -
voir is located inside the engine.

solutions mean a consistent

Lightweight construction.
Both Cayman models are
equipped with alloy engines. The
ingenious design, down to the
finest detail, keeps the weight of
the engines low and therefore
reduces fuel consumption. One of
the ways in which this light weight from the cylinder heads directly

To reduce power loss and increase

combined with a high level of

is not a contradiction. During Driving stabilit y is excellent, even

The Cayman models follow a
clear line. Their own. Even when it
comes to the chassis. The driver’s
connection to the road is an
essential priorit y at all times, fast lane changes and through
tight corners, this chassis is in its
element. Thanks to the mid- engine
layout and the construction of
the bodyshell, roll and pitch are
practically eliminated. The chassis
responds with absolute precision
along with the delivery of the
engine’s power.
For this reason, the Cayman
models are equipped with
a light weight suspension with
transverse links and spring to acceleration and braking. The
light weight construction keeps
the vehicle gross weight and the
weight of the unsprung masses
low. Virtually all moving axle parts
are made of aluminium.

Braking system.
The acceleration of the Cayman
models is impressive. Even more

impressive, perhaps, is the vehicle’s
maximum braking power, which
comfortably tames the power of
the engine.
Four-piston aluminium monobloc
brake calipers are fit ted front and
rear. Offering excellent rigidit y,
they are compact and save on
weight. Their superior responsive -
ness, for fast and sensitive
braking, sets them apart. A brake
booster provides assistance,
reducing pedal effort whilst main -
taining a powerful braking effect.
A special ventilation system,
whereby the entire wheel brake
is supplied with cooling air by
openings in the front end and
special channelling systems,
increases the stabilit y of the
brakes during heav y use. The front axle of the Cayman
and Cayman S features internally
vented brake discs with a diameter
of 318 mm. 299 mm brake discs
are fit ted to the rear axle. The
result is outstanding braking

performance. The rear brake discs
of the Cayman S are 4 mm thicker
than those of the Cayman, which
increases stabilit y under load even
further. To distinguish them visually,
the brake calipers on the Cayman
have a black anodised
finish while
those on the Cayman S
are painted
red.
For reduced weight, optimum
braking in the wet and improved
cooling, the brake discs on both
models are cross- drilled.
For the Cayman S, the Porsche
Ceramic Composite Brake (PCCB)
is available as an option.

In an era of intensif ying debate
about global climate change and
CO
2 emissions, every automotive
manufacturer is asking itself
what it has to of fer in terms
of environmental protection. Our
answer has long been the same:
maximum ef ficiency.
Over the last 15 years, Porsche
has managed to reduce the
fuel consumption of its vehicles
by an average of 1.7 % each year.
Improvements in fuel economy
also have a beneficial impact
on CO
2 emissions. This has been
achieved through an ef ficient
drive concept (DFI), light weight
construction, optimum aerody -
namics and low rolling resistance.
The goal? Pure performance – but
not at the expense of the environ -
ment. A goal achieved by the
Cayman models.
Exhaust emission control.
Both engines comply with the Euro
5 emission standard

strate that even

category. In short, the Cayman
is not only sport y, it is also clean.
This at tribute is achieved by
means of a t wo -stage cascade-
t ype cataly tic converter
which comprises t wo monolith
substrates on each of the t win

coated substrates contain
ultra-fine honeycomb channels in
