The CaymanThe Porsche Cayman has always
been there, waiting for the
right opportunity. Mysterious yet
familiar, its presence could be felt
throughout the history of Porsche.
So we chose to explore it, giving
free rein to our wilder, more intuitive
side. Naturally, we incorporated allof our experience in both road and
race engineering.
The new Cayman and the Cayman S
are a challenge to conventional
ways of thinking. They successfully
resolve so many apparent
contradictions, uniting the extremesof design, practicality and
performance.
Together, they epitomise the
sportscar experience with absolute
clarity and precision. They represent
a fundamental idea that has always
been instantly Porsche.

The handling of the car is even
more alert when fitted with the
optional Sport Chrono Package
(see page 54). This exclusive
performance upgrade includes
a dashboard-mounted analogue
and digital timer unit. When ‘Sport’
mode is selected, the engine
and chassis are seamlessly
switched to a more direct and
positive setup. The throttle is
more responsive, PSM (see page
64) inputs are reduced, and the
optional PASM (see page 52) is
also switched to its firmer ‘Sport’
mode settings.On vehicles with optional Porsche
Communication Management
(PCM – see page 86), the system
can be upgraded to the Sport
Chrono Package Plus (see page
55). Additional features include
a performance display in PCM
and a personal memory function.
Occupant protection is matched
to performance using a system of highly robust side and cross
members which absorb impact
energy in a safe and calculated
manner. Standard safety features
include full-size front airbags andPorsche Side Impact Protection
(POSIP – see page 66). The POSIP
package features separate head
and thorax airbags as well as
side-impact protection beams.

are logically arranged within easy
reach of the driver.
The standard seats offer excellent
comfort and lateral support. You
can also choose from a range
of optional alternatives, including
pneumatically adjustable adaptive
sports seats (see pages 74/75).
The coupé body on both the
Cayman and Cayman S unites
style with practicality. Beneath therear lid with large glass screen
is a generously proportioned
luggage compartment featuring
two main storage areas. Offering
260 litres of loadspace, it is joined
by a further 150 litres at the
front, making 410 litres in total.
Equally generous is the quality of
sound from the standard CDR-24
audio system. Optional additions
include the Sound Package Plus
which provides enhanced acoustic
performance. For perfect in-car
audio, there’s the BOSE
®Surround
Sound System (see page 84),
offering concert-hall quality through
a total of 10 loudspeakers.
In summary, each car provides a
unique combination of everyday
practicality, exceptional active
safety and uncompromising,
dynamic performance. These
apparent contradictions are
successfully reconciled within a
proven and elegant vehicle
concept that is perfectly realised
on the road.

The Cayman design philosophy.
A single glance is all it takes
to recognise a Porsche. Look a
little closer and you’ll find a
sporting character unique to the
new Cayman and the Cayman S.
Sinuous, muscular, from front
to rear, they are poised and ready
to perform.Energy and potential are clearly
expressed in the dynamic interplay
of concave and convex forms.
Viewed from the front, this
powerful capability is immediately
conveyed by the large air-intake
openings. Their distinctive design
gives each Cayman model a
unique and provocative look.
Neatly positioned within the
outermost intakes are the twin
fog and side light units. Their
rounded form is elegantly
combined with horizontal aerofoil
elements. Splitter elements at
the base of the front apron
provide a further reduction in
front-end lift.

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.

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’
lighting, optional automatic air
conditioning and door-lock
settings.

Both Cayman models, like every
Porsche, have lots of performance
in reserve.
To help you explore even more

the engine dynamics become

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.

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.
