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.

Model rangeIt’s one thing having a good idea.
Applying it is another entirely. Doing
so requires tenacity and persistence.
A desire for perfection. Particularly
in the case of a Porsche.
How do we know when an idea is
good? When it not only captures our imagination, but also won’t
let it go. The new Cayman and
the Cayman S are two prime
examples. Each unites uncom-
promising performance with
exceptional everyday practicality.
This ability to reconcile apparent
contradictions is a quality theyshare with every Porsche. And like
every Porsche, they successfully
redefine the essential sportscar
concept. Each one presents its
own unique interpretation with its
own inimitable style.

The new Cayman

The Cayman S

· 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.

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.

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.

Integrated dry-sump
lubrication.
This proprietary Porsche
technology ensures consistent
lubrication in even the most
extreme high-speed corners.
Oil is extracted from each of the
cylinder heads by a dedicated
scavenge pump. The oil return
system features narrow-section
lines which de-foam the oil before
it is collected in the integral sump.
A third pump then feeds the oil
back to the lubrication points and
the cycle begins once more. A
stable oil pressure is maintained
throughout the engine, even
during racetrack use.
Oil-level indicator.
Both Cayman models have an
electronic oil-level indicator as
part of the on-board computer
system. The reading is so precise
that a conventional dipstick is not
required.
Engine cooling.
Both flat-six engines have a
cross-flow cooling system with
all coolant channels cast in the
block. With no external hoses
or pipework involved, the system
is much more secure than
conventional designs.
Coolant is supplied separately
to each individual cylinder, so
it never arrives pre-warmed. As
well as maintaining a consistent
engine temperature, this means
the valves are much less
susceptible to wear. Important
benefits include greater engine
reliability, less risk of knocking,
better fuel economy, lower
emissions and reduced mechanical
noise.
Engine management system
with electronic throttle.
The Motronic ME7.8 engine
management system is the
primary source of control for
all engine-related systems and
processes, e.g., ignition and
fuel supply. It is an essential
prerequisite for enhanced
performance in all operating
conditions. The electronic throttle
is not only more precise, it can
modulate the volume of incoming
air to compensate for sudden load
transfer (e.g., when lifting off the
throttle before braking). Electronic
engine management ensures
better power delivery from a
standing start and a smoother rev-
limiter action. It also coordinates
the various sub-systems within the

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

Tiptronic S.
Both Cayman models are available
with five-speed Tiptronic S as
optional equipment. This versatile
system combines an automatic
transmission with the option of
manual gearshifts.
For manual control, simply slot
the gear selector into the manual
gate and use the gearshift controls
on the steering wheel. Press up
to change up, and down to change
down. Gearshifts are performed
in around 0.2 seconds with
virtually no interruption in drive.
The action is comparable with
that of a manual gearbox.
Switch to automatic, and you can
still change gear by hand using
the rocker controls on the steering
wheel. This race-derived function
is particularly useful during
overtaking manoeuvres. If there
is no manual input for a period
of eight seconds, the system will
revert to automatic mode. The
drive position and gear selection
are displayed at all times on a
dedicated cockpit display.
In automatic mode, Tiptronic S
can choose from a range of
gearshift points for each individual
gear. The standard gearshift
pattern, designed for maximum
fuel economy, can be steplessly
varied up to a dedicated ‘Sport’
configuration for optimum high-
performance driving. Each
gearshift point is automatically
selected based on current road
conditions and driving style. Within
a short space of time, you’ll
develop a feel for the system and
begin to influence gearshifts using
the throttle alone. The benefits
of Tiptronic S are particularly
apparent when exploring the car’s
performance. Even in automatic,
the rapid gearshift action
enhances the agility of the car.
