Chassis
Suspension.
A mid-engined layout with low
centre of gravity provides the
perfect foundation for agile,
dynamic performance. Combined
with a rigid bodyshell construction,
the potential benefits are multiplied.
All it takes to reap those benefits
and apply them to the road is a
suitable chassis concept.
On both Cayman models, that
chassis is based on McPherson-
strut suspension at front and
rear. Proven by Porsche on roadand track, this simple combination
of coil-over struts and lateral
control arms is key to the
character of the car. When
designing the suspension, the
absolute priority was to bring
maximum drive to the road. This
immediacy of response shouldalso be matched by the quality
of feedback and comfort.
To achieve those objectives,
we’ve used a generous ‘track’
or distance between the wheels
on each axle. Springs, shock
absorbers and anti-roll bars are
rated for high-speed cornering.
Lightweight materials, intelligently
applied, provide a further
reduction in sprung and unsprungmass. Virtually all moving parts
on the axle assemblies are made
from aluminium.
The resulting chassis is equally
accomplished during high-speed
manoeuvres and in tight, twisting
bends. There is no unwanted
movement within the suspension,
and virtually no susceptibility
to pitch and roll under cornering,
acceleration and braking.
Performance is matched by
exceptional active safety on every
type of road. The stability of the
car is extremely good, enabling a
sensitive response in every road
scenario. In simple terms, that
means greater reserves of safety,
regardless of load, as well
as natural resistance to lift-off
oversteer. Cornering stability
is second to none, even during
racetrack use.
The optimum connection
between driver and road.

Safety
Power is only one aspect of performance.
It is nothing without control.
Safety in the Cayman and Cayman S.
Active safety.
Active safety is an integral part of
every new Porsche design. Each
new vehicle concept incorporates
systems and components which
are developed with one aim in
mind: total safety for you and your
passengers.The suspension and steering – the
basic platform of the car – have a decisive role to play. On the
Cayman and Cayman S, they offer
generous reserves of safety,
even at racetrack speeds. Equally
important are the reserves
of power, which enable rapid
overtaking manoeuvres. Bringing
Night-time driving is equally
assured thanks to a highly
effective front and rear lighting
concept. The low front foglights
offer excellent illumination,
precisely where you need it most.
A high-level third brake light is
neatly integrated at the base of
the large rear screen. In addition
to the obvious safety benefits,
the front and rear lighting on the
Cayman and Cayman S create
a unique ‘night design’.
Bi-Xenon lighting system with
headlight cleaning.
This optional headlight system
offers greater light output in
low-beam mode, improved
illumination up to the light/dark
border, better lateral visibility and
reduced driver fatigue thanks
to a higher colour temperature.
A dynamic headlight levelling
function raises and lowers the
angle of each light to compensate
for changes in the attitude of the
car under braking and acceleration.

system.
Downforce is provided by a bi-plane
rear spoiler and aerodynamic front
end. Another important standard
safety feature is Porsche Stability
Management (PSM – see page 64).

Load-carrying capability.
The Cayman and Cayman S are
purposefully designed to make
every journey a pleasure. Not
only when enjoying each car for
its own sake, but whatever your
destination. Suddenly, even a trip
to the shops takes on a whole
new level of appeal. You’ll also
find yourself ideally prepared for
all kinds of leisure activity. From
diving in the ocean to trekking
in the hills, both Cayman models
have the carrying capacity for
everything you need.
The generous load concept
includes two luggage compart-
ments, a wide range of interior
storage, and an optional roof
transport system. As a result,
the Cayman and Cayman S are
both eminently practical and
consistently enjoyable, whatever
the reason for your journey.
Front luggage compartment.
The front luggage compartment is
carpet-lined and offers 150 litres
of loadspace. A covered nicheprovides a secure location for the
navigation DVD drive (included
with optional navigation system)
and the optional CD autochanger.
Rear luggage compartment.
The rear compartment beneath
the soft-lined hatch can also
be loaded from inside the car.
Fully carpeted, it comprises two
storage areas: a flat surface
on the engine cover and a main
luggage area to the rear. This
arrangement enables easy loading
of longer items of luggage.
The rear luggage area is both
generously proportioned –
totalling 260 litres – and elegantly
matched to the rest of the car.
As an optional enhancement, you
can apply your chosen exterior
colour to the panels surrounding
the engine cover and the integral
strut tower mouldings
(see InteriorDesign package).
A retaining rail at the front of the
engine cover helps to secure
any luggage under braking. This
can be augmented by an optional
full-size partition which installs
Front luggage compartmentLuggage partition
immediately behind the seats.
Smaller items can be secured
on top of the engine cover using
a luggage net with four lashing
eyelets. A stainless steel ‘bridge’
provides an elegant transition
to the lower rear luggage area.
This compartment is designed
for larger items of luggage and
also has four lashing eyelets.
Another useful feature in the rear
compartment is the covered
service opening with filler tubes
for coolant and oil.

Exhaust emission control.
Four-valve cylinder heads and
VarioCam Plus ensure minimal
emissions at source. After leaving
the engine, the gases are cleaned
by a system of four catalytic
converters and four ‘Lambda’ or
oxygen sensors. Controlling it
all with optimum efficiency is
the Motronic ME7.8 engine
management system. Each bank
of cylinders has its own Lambda
circuit, enabling precision
adjustment of the air/fuel mix.
Each exhaust tract has two
Lambda sensors, one upstream
and one downstream of the
primary catalyst.* The resulting
benefits include full compliance
with both the EU4 emissions
standard and ULEV II regulations
in the United States, as well as
excellent fuel economy.
Noise.
The Cayman and Cayman S comply
with all current noise regulations
without any form of engine
encapsulation. To do that, we’ve
eliminated noise at source in
every area of each car. Engine
components are rigid, moving
parts are light, and tolerances
have been reduced to a minimum.
The result is a pure and distinctive
sound – with all the character
you’d expect from a Porsche.
Fuel system.
All fuel lines are made from robust
aluminium, while those carrying
vapours are multi-layer plastic. The
result is a significant reduction in
the evaporation of hydrocarbons.
Materials and recycling.
All structural components,
switchgear and trim are made
from fully recyclable materials.
Better still, it is highly unlikely
that they will ever need recycling
at all. Long-term durability is,
after all, one of the defining
qualities of every Porsche car.
A key objective during the
development process was all-
round weight reduction. This was
achieved using cast aluminium
alloys, synthetic materials and
high-tensile metals. Used correctly,
this blend of materials is both
stronger and lighter than
conventional
steel. As well as
reducing fuel consumption, it
offers positive environmental
benefits.
Approximately 85 % of all com-
ponents can already be recycled
using today’s technology. This
proportion is set to increase as

Environment
new thermal methods are
introduced. To simplify recycling,
all synthetic components are
clearly labelled in accordance
with the relevant standards.
Both Cayman models are entirely
free of CFCs and components
manufactured with the aid of
these chemicals. Water-based
paints are used throughout each
car, thereby reducing the need
for chemical solvents during the
production process.
Servicing.
Longer service intervals are not
only more convenient for you, they
are also better for the environment.
With the new Cayman and
Cayman S, we have achieved
very modest servicing
requirements: engine oil every
20,000 miles (or two years),
oil filter every 20,000 miles, air
filter every 40,000 miles, spark
plugs every 60,000 miles (or
four years), and brake fluid every
two years.
In addition to the obvious
environmental benefits, the
advantage for you is two-fold: a
lower cost of ownership throughout
the life of the car, and more time
spent on the road. Based on
mileage alone, the new Cayman
models require just three stops
for servicing every 60,000 miles,
or one service every two years.
