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.

At Porsche, we have always
followed our instincts. To
make cars which follow yours.
Responding directly with
precision and immediacy to
every input you make.
Instinct is all about being in the moment.
For us, that’s something of a tradition.
The new Cayman and the Cayman S.
Achieving that level of vehicle
response requires careful
consideration. It takes many
years of continuous evolution to
arrive at each new revolutionary
development.The new Cayman and the Cayman S
are pure, direct and involving. They
also exude a familiar Porsche
character more than five decades
in the making.
The new Cayman and the Cayman S |The Cayman
The key to that character, as on
every Porsche, is the underlying
vehicle concept. This unique
combination of mid-mounted engine
and hard-roof body was originally
prototyped in 1953 on the
Porsche
550 coupé. A closed-top
version of the legendary 550
Spyder, it was specially developed
for the 24 Hours of Le Mans.
Now we’ve combined this race-
winning concept with more than
five decades of road and race
experience. The result: the new
Cayman and the Cayman S.
Each is powered by a free-revving,
high-torque, mid-mounted engine
with a low-lying centre of gravity.
The new Cayman has a 2.7-litre
flat-six unit developing 180 kW
(245 bhp) and 273 Nm of torque.
The Cayman S produces 217 kW
(295 bhp) and 340 Nm from a
displacement of 3.4 litres. Both
cars deliver maximum torque from
surprisingly low engine speeds.Powerful acceleration is instantly
available, in every situation.
The respective top speeds are
258 km / h (160 mph) on the
new Cayman and 275 km / h
(171 mph) on the Cayman S.
Each car has an elegant and
purposeful exterior design,
offering more than just visual
appeal. The coupé body is
aerodynamically refined, producing
a drag coefficient of just 0.29
(Cayman S with Tiptronic S: 0.30).
The monocoque shell has
additional benefits in terms of
torsional and flexural strength.
This in turn promotes greater
agility and positive driving
dynamics.
The precision handling is a
direct result of uncompromising
chassis engineering. The
standard suspension offers agile
performance as well as excellent
long-distance comfort. The front
and rear axles feature McPherson-
strut suspension, a wide track
and generous wheel dimensions.
Combining it all is the most
important factor: the overall
suspension setup. Stable and
responsive, it is, of course,
balanced with appropriate levels
of comfort.
Matching the suspension in
terms of agility and safety are
the standard Porsche Stability
Management (PSM – see page
64) and the variable-ratio steering
system. Together, they enhance
your involvement with the car,
offering almost surgical precision
on turn-in to a corner and
increased safety in critical
scenarios.
For even greater performance
and occupant comfort, there’s
the optional Porsche Active
Suspension Management (PASM –
see page 52). This 10-mm
lowered variable suspension
system provides active control
of the damping force on each
wheel based on changing road
conditions, individual driving style
and the selected setup mode
(‘Normal’ or ‘Sport’).

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
The new Cayman and the Cayman S |The Cayman
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.

Evolved for the enjoyment of driving.
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.

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.

instrument cluster with classic
black instrument dials. The
instrument shroud unites all three
instruments into a single visual

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
The new Cayman and the Cayman S |Model range
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
compartment lids on the
doors and centre console.
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.

DriveThe heart and soul of any
sportscar is, above all, the
engine. In both Cayman models,
it’s in the right place: directly at
the centre of the car. Just how
much of a difference that makes
is reflected in the engine data.
What the data does not convey ishow that performance is applied.
This attribute – the character of
each car – can only be measured
by the driver. With the engine
revving directly behind you, the
relationship is almost symbiotic.
Every input is eagerly met with a
precise and emphatic response.
