Porsche Active Suspension
Management (PASM).
PASM is an electronic damping
control system. Available on
both Cayman models, it offers
continuous adjustment of
individual damping forces based
on current road conditions and
driving style. Agility and driving
pleasure are significantly
enhanced while retaining the
car’s natural ride quality. Equipped
with PASM, the car rides 10 mm
lower than with the standard
steel-sprung suspension.
The driver can choose one of
two setup modes, ‘Normal’ or
‘Sport’. While the first is a blend
of performance and comfort, the
‘Sport’ setup ratings are generally
much firmer, enabling greater
agility on the racetrack. In either
mode, the system responds to
changing loads by automatically
applying the optimum damping
rate on each individual wheel.
The rates are selected from a
range of map options which are
specially adapted to the unique
dynamics of the Cayman and
Cayman S.
The movement of the body is
continuously monitored under
acceleration, braking and cornering
manoeuvres, as well as on poor
road surfaces. Other sensors
provide additional information on
lateral acceleration, steering
angle, brake pressure and engine
torque. A dedicated control unitprovides real-time analysis and
damper adjustment as defined
for the respective setup mode
(‘Normal’ or ‘Sport’). The result:
greater stability and more
consistent occupant comfort.
If, when ‘Sport’ mode is selected,
the quality of road surface drops
below a certain threshold, the
system immediately switches
to
a softer rating and restores
the car’s traction and grip.
When the road surface improves,
PASM returns to the original,
harder ratings. The system
remains active in ‘Normal’ mode,
too, automatically switching to a
harder setup if the car is driven
more assertively. As the dampers
become stiffer, the car becomes
more stable and driver control is
improved.

a more natural and involving
response to lateral and longitudinal
forces. Cornering agility is
considerably enhanced, with
greater scope for oversteer on
turn-in and exit. This additional
manoeuvrability is particularly
apparent in lower-speed sequences
and bends.
For maximum dexterity, PSM can
be set to standby while the car is
still in ‘Sport’ mode. PSM simply
monitors the forces acting on the
car and will only intervene in the
most critical scenarios, e.g., when
ABS assistance is required on both
front brakes.
To help you quantify this increase
in performance, the Sport Chrono
Package includes a compact timer
with swivel display which is
centrally located on the dashboard.
Functions are accessed via the
control stalk for the on-board
computer. Analogue dials measure
hours, minutes and seconds, while
a separate digital field displays
whole seconds, tenths and one
hundredths of a second. The digital
field runs in parallel with a second
digital display which is conveniently
located in the instrument cluster.
Sport Chrono Package Plus.
This enhanced Sport Chrono option
is available in conjunction with the
optional Porsche Communication
Management (PCM – see page 86).
It offers all the same functions as
the Sport Chrono Package as well
as some additional information
options and features.

Lap or journey times can be
viewed, stored and analysed using
a special performance display in
PCM. The information available
includes time elapsed and
distance travelled on the current
lap, as well as the number of laps
completed and their respective
times. You can also view the
current fastest lap as well as the
remaining range till empty. Driving
times can be recorded for any
stretch of road, and benchmark
times defined. Other useful features
include a personal memory
function which is also controlled
via PCM. This can be used to store
personal preferences for a range
of systems, including daytime
running lights, ‘Welcome Home’

Sport Chrono Package.
Both Cayman models, like every
Porsche, have lots of performance
in reserve.
To help you explore even more
of that potential, there’s the
optional Sport Chrono Package.

rev limiter becomes harder, and
the engine dynamics become
more like those of a racing car.
While this is happening, the
optional sports exhaust system
(see page 41) and optional PASM
are also switching to ‘Sport’ mode.
The baseline damper rating is
now considerably firmer, enabling
faster turn-in as well as better
road-holding and traction.On vehicles equipped with
optional Tiptronic S, the automatic
gearshift is noticeably more
dynamic. Upshifts and downshifts
are performed at higher revs with
a faster gearshift action. When
you lift off the throttle to slow the
car, engine braking is applied
sooner. There are no unwanted
upshifts in manual mode when
approaching the engine speed limit.

lighter than metal, but also
harder and more resistant to
high temperatures.
Within each disc is a system of
internal channels which provide
highly efficient heat dispersal,
particularly during heavy use. An
area of ongoing development,
we’ve now doubled the number
of channels and optimised the
airflow characteristics. With twice
the number of internal walls, thenew PCCB disc has even greater
structural stability. The ring of
vent openings around the outer
rim is one of the key distinguishing
features of this technology.
Matched to the disc is a special
brake-pad compoun d offering
rapid deceleration and consistent
friction properties. The front pads
are mounted in six-piston monobloc
aluminium calipers, while those at
the rear come in four-piston units.
Porsche Ceramic Composite
Brake (PCCB).
The Cayman S is also available
with a carbon fibre-reinforced
ceramic brake system: the
Porsche Ceramic Composite
Brake (PCCB). The PCCB disc is
made from a specially treated
carbon-fibre compound that is
silicated in a high-vacuum process
at 1,700 ºC. The result is a
product that is not only much
The overall response is fast and
precise, with only moderate pedal
force required. The front disc
diameter – 350 mm – is larger
than that of the standard metal
disc. The longer radius brings
increased leverage and therefore
additional performance.
Even at high temperatures, the
thermal resistance of the ceramic
disc ensures excellent dimensional
stability. The ceramic material istotally resistant to corrosion and
offers excellent acoustic damping
properties. Braking distances
are significantly reduced in even
the toughest road and track
conditions. Inherent fade resistance
ensures optimum balance when
slowing the car from high speed.

The key advantage of PCCB is
its ultra-lightweight construction.
Compared with conventional metal
discs, it offers a remarkable
weight saving of approximately
50 %.
As well as enhancing performance
and fuel economy, this represents
an enormous reduction in both
unsprung and rotating mass –
important factors when it comes
to handling, agility and comfort.

Safety
it can never suspend the laws of
physics, PSM does provide that
extra margin of safety whenever
you need it most. A key component
in PSM is a specially optimised
anti-lock braking system (ABS)
offering safer deceleration and
shorter braking distances. PSM
is also invaluable when applying
the throttle on low-grip surfaces.
Here, it uses the ABD (automatic
brake differential) and ASR
(anti-slip regulation) functions to
maintain traction and stability.
In order to retain the car’s natural
agility, PSM combines a high
trigger threshold with precision
input characteristics.
Porsche Stability
Management (PSM).
This automatic vehicle stability
control system is standard
equipment on both Cayman
models. Throughout each journey,
PSM uses a range of sensors to
monitor the direction, speed, yaw
velocity and lateral acceleration
of the car. Using this information,
it is possible 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 to restore
stability and optimum speed. WhileThe PSM threshold is raised
higher still when ‘Sport’ mode is
selected on the optional Sport
Chrono Package/Sport Chrono
Package Plus. The resulting
drive is much more involving,
particularly at speeds up to
around 70 km / h (44 mph). If
you’d rather enjoy the car
unassisted, the system can be set
to standby. When ‘Sport’ mode is
selected, PSM will only intervene
under heavy braking where both
front wheels are in danger of
locking. In ‘Normal’ mode, PSM
automatically becomes active
as soon as one of the front
wheels requires ABS assistance.The upper section of each door
features additional reinforcements
(3) which enhance the rigidity of
the car. This upper load path (4)
is used to channel energy into
the side of the car and thus
provide additional protection for
the passenger cell.
Passive safety.
Both Cayman models easily
comply with all statutory
requirements in respect of frontal,
side, diagonal, rear impact and
rollover protection.
The bodyshell structure contains
a highly resilient passenger
cell offering exceptional crash
protection. At the front of the
car, the cell is protected by a
patented system of longitudinal
and transverse members (1). In
the event of an accident, energy
is absorbed and distributed by
the front-end structure, thereby
minimising cell deformation.
Additional features include a
bulkhead cross-member (2) made
from super high-strength steel.
This element is designed to
absorb impact forces from the
longitudinal members and thus
protect both front footwells.

‘Welcome Home’ lighting.
This standard lighting function
provides comfort and safety
when using the car after dark.
The foglights and taillights are
automatically illuminated when the
car is locked or unlocked using
the key remote. The lights remain
illuminated for 30 seconds,
lighting your way to or from the
car. This delay is user-adjustable
on vehicles with optional Sport

(PCM).
HomeLink®.
This optional garage-door opener
is freely programmable and
integrated within the cockpit. It
offers remote control of up to
three garage, gate, home lighting
and/or alarm systems. Compatible
with virtually all garage and gate
systems.
Water-repellent side windows.
The side window glass on both
Cayman models has a highly
effective water-repellent finish. By
rapidly dispersing moisture and
dirt, it ensures optimum visibility
in the wet. (Note: surface finish
requires occasional renewal
depending on vehicle usage.)
Front wipers.
The front wipers have an adjustable
wipe interval, are aerodynamically
designed and park neatly out
of sight when not in use. The
right-hand blade has a bowed
construction enabling maximum
wiper coverage. The windscreen
washer system features two
heated nozzles with integral filter
element. An optional rain sensor
is also available in conjunction
with the auto-dimming interior and
exterior mirrors.

BOSE® Surround Sound System.
The engine and exhaust on the
Cayman and Cayman S create
their own unique sound experience.
For the perfect accompaniment,
choose the lifelike audio of the
optional BOSE
®Surround Sound
System. Jointly developed by
Porsche and BOSE
®, it is perfectly
engineered for the interior
acoustics of both Cayman models.
A total of 10 loudspeakers,
including an active subwoofer with
integral 100-Watt switching amp,
deliver crystal-clear surround
sound output. The lifelike spatial
quality is equally impressive in
either seat position.Powering it all is a seven-channel
MOST
®-based digital amplifier
featuring 5 x 25-Watt linear amps
and a single 100-Watt switching
unit. AudioPilot™ noise compen-
sation technology provides
automatic adjustment of tone and
volume based on current road
speed and ambient noise. The
result is a noticeably clearer and
more consistent sound, with
no need for continuous manual
adjustment.
Active equalisation matches
all sound output to the unique
acoustics of the Cayman and
Cayman S. Covering the entire
frequency spectrum, it delivers
lifelike audio to both seat
positions.
The dynamic loudness function
included with the system is a
more sophisticated alternative to
conventional technologies. By
enhancing the lower frequencies
in low-volume sound, it actively
compensates for the reduced
sensitivity of the human ear at
the lower end of the range.The key system component,
BOSE
®Automotive Surround
Sound, uses independent
channels at front and rear to
create a push-button panorama
of space and sound. The sense
of depth is further enhanced
with the aid of patented BOSE

to Centerpoint™ technology,
even stereo recordings can be
split into five separate channels.
Together, these technologies
provide a breathtaking alternative
to the car’s natural engine
acoustics. Completing the

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
* Not featured in markets with leaded fuel.The new Cayman and the Cayman S |
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.
