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’).
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.

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

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

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.

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.

The brakes are cooled using a
special ventilation system which
channels air from the front
of the car to every part of each
assembly. This arrangement
ensures consistently high levels
of performance and durability,
particularly during heavy use.
The internally vented discs on the
new Cayman measure 298 mm
in diameter at the front of the car
and 299 mm at the rear. On the
Cayman S, the front diameter
is 318 mm. On both models, the
discs are cross-drilled to improve
wet-weather response and
minimise unsprung weight. The
calipers on the new Cayman
have a black anodised finish, while
those on the Cayman S are
painted red.

Both the Cayman and Cayman S
are exceptionally quick under
acceleration. Even more impressive
is the speed of response from
the standard braking system.
Several times more powerful
than the flat-six engine, the
brakes are crucial to the overall
performance of each car.
All four brake calipers have a
four-piston monobloc aluminium
construction. Key characteristics
include excellent rigidity, compact
dimensions and a very modest
contribution to unsprung weight.

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.

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.
