A fundamental principle of Porsche
engineering is the search for
efficient performance. In the
Cayman S, the six-cylinder boxer
engine develops 217 kW (295 bhp)
from a 3.4-litre displacement.
Maximum torque of 340 Nm is
available between 4,400 and
6,000 rpm. VarioCam Plus
(see page 39) helps to increase
torque at lower engine speeds
and optimise top-end power. Theresults? An immediate response
to throttle inputs, 0 to 100 km / h
(62 mph) in as little as 5.4 seconds,
and a top speed of 275 km / h
(171 mph).
Working with the engine to achieve
that performance is a highly refined
aerodynamic package. Indeed, the
Cayman S has a drag coefficient
of just 0.29 (with manual gearbox;
Tiptronic S: 0.30).
Power and torque are applied
with precision through a short-
throw six-speed manual gearbox.
Tiptronic S is available as an
option, offering fully automatic or
manual gearshifts via rocker-type
controls on the steering wheel.
Externally, the Cayman S differs
from the Cayman in its colour-
coded lip spoilers at the front of
the car and dual-tube tailpipe

design. In keeping with its
higher performance capability, the
Cayman S comes with 18-inch
wheels as standard. The generous
internal diameter accommodates
a standard braking system with
internally vented and cross-drilled
discs which are larger than those
on the Cayman.
The discs are combined with four-
piston monobloc aluminium fixed
calipers featuring a red paint
finish unique to the Cayman S.
As an optional alternative to the
standard braking system, there’s
the ultra-high performance
Porsche Ceramic Composite
Brake (PCCB – see page 62).
As you would expect, the interior
of the car is exclusively designed
around the driver. Every material
exudes elegance and sporting
style. The instrument dials have an
aluminium-coloured background
which is tastefully matched to the
Aluminium Look trim on the gear
console surround and dashboard.
The standard interior includes
a genuine leather finish on the
steering wheel, gear lever,

handbrake lever, door
handle facings and storage

As a finishing touch, there’s a
Cayman S logo on each of the
outer door-sill guards.
Equally attractive are the car’s
lengthy service intervals. Not
only do they minimise the cost
of ownership, they also keep
your car longer on the road.

Ignition system.
The ignition system in the Cayman
and Cayman S features static
high-voltage technology. Separate
coils on each of the plugs ensure
perfect ignition every time. With
no central coil, there is no need
for leads, which are a frequent
source of faults. All six coils are
directly controlled by the engine
management system. This
Cylinder-specific knock control.
Since temperatures tend to
vary across the engine, each
cylinder is monitored separately
for unwanted pre-ignition of the
air/fuel mix. If a risk is detected
in one or more cylinders, the
timing is adjusted on the
corresponding spark plug.
The system is effective under
all engine conditions, including
extremely heavy loads at low
rpm.
Exhaust system.
Both Cayman models have a
specially designed stainless steel
exhaust system. Gas is passed
from each bank of cylinders
through twin cross-linked silencer
units and exits the car through
a central tailpipe. A system of
four oxygen sensors – one before
and one after each of the two
pre-catalytic converters – provides
separate monitoring of the gas
composition and catalyst
performance for each cylinder
bank.
arrangement means they can
also be integrated with other
electronic-based systems. If the
optional Tiptronic S, for example,
requests smoother downshifts,
the system responds within a
fraction of a second and adjusts
the ignition timing.
Since a twin-tract layout allows a
higher rate of throughput than a
conventional exhaust, the system
also has a positive impact on
overall power and torque. It also
contributes to the distinctive
engine sound – on starting, at
idle and across the entire engine
speed range.
For even more powerful acoustics,
both cars can be equipped with
an optional sports exhaust system.
Servicing.
Regular servicing is extremely
important on any high-precision
machine. In the case of a
Porsche, it is equally important
to give you maximum enjoyment
from your car. We therefore aim
to reduce servicing requirements
and extend all service intervals.
The generator, power-steering
pump and air-conditioning
compressor are all driven by a
single, self-adjusting belt. Under
normal usage, the drive chains
for the cam and auxiliary shafts
are entirely maintenance-free.
The ignition system is also
maintenance-free, with the sole
exception of the spark plugs
(60,000 miles). The engine oil
interval is 20,000 miles, while
hydraulic tappets provide
automatic clearance adjustment
on each of the 24 valves.
In short: when we design a car
for the road, that’s where we
intend it to stay.Exhaust system

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

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.

navigation is housed in the front
luggage compartment. One of the
benefits of this arrangement is
that the MP3-compatible CD drive
in PCM can be used exclusively
for audio CDs.
On-board computer.
The standard on-board computer
provides a wide range of
information, including average
fuel consumption, average speed,
range till empty and audio data.
It can also be used to view data
from the optional Tyre Pressure
Monitoring (TPM). Information is
accessed using a control stalk on
the steering column and viewed in the central instrument display.
If combined with the optional
PCM, you can access additional
data and functions such as
average values and driver-defined
speed-limit warnings. The control
stalk for the computer is also
used to select the analogue and
digital timing functions in the
optional Sport Chrono Package

EnvironmentThere are two possibilities when
it comes to protecting the
environment: react to regulations
or establish your own and
incorporate them within the
development process. For us,
there has only ever been one
way. With the Cayman and
Cayman S, we have followed that
path as on every Porsche before.
So while their powerful capability
is second to none, it doesn’t
come at any price. At Porsche,
the principle of high performanceextends to every area of the
car. Including its relationship
with the environment. That is our
commitment with the Cayman
and Cayman S. Why settle for
anything less?

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.
