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.
The lightly domed roof creates
a bright and spacious interior.
The passenger compartment is
ergonomically designed with a
range of high-quality materials.
The cockpit area is precisely as
you would expect – exclusively
created for driving. The steering
wheel is adjustable for height and
reach, while all major controls

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.

· 21 · · 20 ·
At the rear of the car, you are
immediately drawn to the heavily
contoured wings. Particularly
striking is the dramatic transition
to the raking C-pillar line. The
balanced combination of concave
and convex surfaces creates a
fascinating play of light.Another important – and practical
– feature is the large rear hatch
and screen. The top-hinged lid
provides convenient access to the
two-part luggage compartment.
A high-level third brake light is also
included as an integral part of
the rear screen. As the eye runs
downwards to the base of the
lid, there’s a stylish bi-plane
spoiler. The upper wing element
is automatically extended at
120 km / h (75 mph), and
generates additional rear-end
downforce.
The downward sweep over the
rear bumper moulding is neatly
punctuated by a horizontal crease
that runs beneath the number
plate recess. Immediately below
is the tailpipe unit – single-tube
on the new Cayman, dual-tube on
the Cayman S. The tailpipe is
flanked by twin aerofoil elements
within an arched vent opening,
which provides a partial view of
the engine exhaust system and
an effective outlet for excess heat.
All that remains is one more
detail – or four, to be precise.
The new Cayman has specially
developed 17-inch wheels with an
attractive twin-spoke design. The
Cayman S comes with 18-inch
wheels as standard equipment.
Derived from the wheel on the
Carrera GT, the outer surface
runs flush with the exterior of
the car. For a more personal
touch, you can also choose from
a range of wheel options up to
19 inches in diameter.
Even externally, both Cayman
models reflect their ability to
reconcile extremes. On the one
hand muscular, powerful and
dynamic, there is also elegance
in every line and form. From
the very first glance, from every
perspective, they are clearly and
instantly Porsche.
The new Cayman and the Cayman S |The Cayman

· 25 ·
Designed entirely around the
driver, the new Cayman is a
contemporary interpretation of
a classic Porsche concept. The
six-cylinder boxer engine has a
2.7-litre displacement generating
180 kW (245 bhp) at 6,500 rpm.
Thanks to VarioCam Plus (see
page 39), the maximum torque
output of 273 Nm is available
between 4,600 and 6,000 rpm.
The mid-engined layout is a crucial
factor in the near perfect front/
rear weight distribution. It also
enhances the car’s rear-end
traction, enabling 0 to 100 km / h
(62 mph) in as little as 6.1 seconds.
Maximum speed in appropriate
track conditions is 258 km / h
(160 mph).
The second key factor when it
comes to performance is, of
course, aerodynamics. Honed in
the wind tunnel, the new Cayman
has a drag coefficient of just 0.29.
Power is transmitted with precision
to the road through a five-speed
manual gearbox. An optional Sport
package is also available,
The new Cayman and the Cayman S |Model range
combining a six-speed manual
gearbox with Porsche Active
Suspension Management
(PASM – see page 52). Five-speed
Tiptronic S, offering both manual
and automatic gearshifts, is
also available as an option.
The standard wheels have a 17-inch
diameter and attractive dual-spoke
design. Clearly visible behind
them are the four-piston fixed brake
calipers in monobloc aluminium
with black anodised finish. All four
discs are vented and cross-drilled,
enabling better performance in wet weather conditions and lower
unsprung weight.
Other distinctive features on the
new Cayman include black lip
spoilers at the front of the car and
a centrally mounted, single-tube
tailpipe. Accompanying it all is the
familiar sound of the Porsche flat-
six engine.
The interior of the car is an
elegant arrangement of smooth
and clearly defined surfaces.

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.

between driver and road.

Steering.
What use is a perfect suspension
setup without equally effective
steering?
At Porsche, we design these two
key elements as one inseparable
whole. The steering system has
an immediacy and precision that
exactly complement thesuspension. Every steering input is
instantly converted into a positive
and accurate response. This is
achieved through a combination
of high-precision front axle
kinematics and power-assisted,
rack-and-pinion steering with
variable-ratio gearing. At the
straight-ahead position, the ratio
is less direct, enabling smoother
manoeuvres during motorway use.Turn the wheel harder, and the
ratio increases, allowing easier
cornering and parking.
This immediacy of response is
backed by excellent road contact
and a modest turning circle of just
11.1 metres. The result: even
greater comfort and active safety.The standard three-spoke steering
wheel offers generous height and
reach adjustment. The steering
wheel rim has a leather finish in
your chosen interior colour. Two
additional three-spoke wheels –
multifunction and sports – are
available as optional equipment
(see pages 107 and 109).
Wheels.
The new Cayman comes with
17-inch wheels as standard
featuring an attractive twin-spoke
design. The Cayman S runs on
18-inch wheels with five-spoke
styling derived from the Carrera
GT. Both standard wheels have a
lightweight construction and run
flush with the exterior of the car.
A range of 18 and 19-inch wheels
are also available as optional
equipment (see page 105). All
standard and optional wheels
come with anti-theft protection.

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

current fastest lap as well as the
remaining range till empty. Driving
times can be recorded for any
stretch of road, and benchmark

highly efficient heat dispersal,
particularly during heavy use. An
area of ongoing development,
we’ve now doubled the number
of channels and optimised the

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.
