Safety
Power is only one aspect of performance.
It is nothing without control.
Safety in the Cayman and Cayman S.
Active safety.
Active safety is an integral part of
every new Porsche design. Each
new vehicle concept incorporates
systems and components which
are developed with one aim in
mind: total safety for you and your
passengers.The suspension and steering – the
basic platform of the car – have a decisive role to play. On the
Cayman and Cayman S, they offer
generous reserves of safety,
even at racetrack speeds. Equally
important are the reserves
of power, which enable rapid
overtaking manoeuvres. Bringing
Night-time driving is equally
assured thanks to a highly
effective front and rear lighting
concept. The low front foglights
offer excellent illumination,
precisely where you need it most.
A high-level third brake light is
neatly integrated at the base of
the large rear screen. In addition
to the obvious safety benefits,
the front and rear lighting on the
Cayman and Cayman S create
a unique ‘night design’.
Bi-Xenon lighting system with
headlight cleaning.
This optional headlight system
offers greater light output in
low-beam mode, improved
illumination up to the light/dark
border, better lateral visibility and
reduced driver fatigue thanks
to a higher colour temperature.
A dynamic headlight levelling
function raises and lowers the
angle of each light to compensate
for changes in the attitude of the
car under braking and acceleration.

halt is a powerful standard braking
system.
Downforce is provided by a bi-plane
rear spoiler and aerodynamic front
end. Another important standard
safety feature is Porsche Stability
Management (PSM – see page 64).

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.

Braking system.
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.
The fast and positive pedal
response is eagerly assisted by a
powerful vacuum brake booster.

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.

Exhaust emission control.
Four-valve cylinder heads and
VarioCam Plus ensure minimal
emissions at source. After leaving
the engine, the gases are cleaned
by a system of four catalytic
converters and four ‘Lambda’ or
oxygen sensors. Controlling it
all with optimum efficiency is
the Motronic ME7.8 engine
management system. Each bank
of cylinders has its own Lambda
circuit, enabling precision
adjustment of the air/fuel mix.
Each exhaust tract has two
Lambda sensors, one upstream
and one downstream of the
primary catalyst.* The resulting
benefits include full compliance
with both the EU4 emissions
standard and ULEV II regulations
in the United States, as well as
excellent fuel economy.
Noise.
The Cayman and Cayman S comply
with all current noise regulations
without any form of engine
encapsulation. To do that, we’ve
eliminated noise at source in
every area of each car. Engine
components are rigid, moving
parts are light, and tolerances
have been reduced to a minimum.
The result is a pure and distinctive
sound – with all the character
you’d expect from a Porsche.
Fuel system.
All fuel lines are made from robust
aluminium, while those carrying
vapours are multi-layer plastic. The
result is a significant reduction in
the evaporation of hydrocarbons.
Materials and recycling.
All structural components,
switchgear and trim are made
from fully recyclable materials.
Better still, it is highly unlikely
that they will ever need recycling
at all. Long-term durability is,
after all, one of the defining
qualities of every Porsche car.
A key objective during the
development process was all-
round weight reduction. This was
achieved using cast aluminium
alloys, synthetic materials and
high-tensile metals. Used correctly,
this blend of materials is both
stronger and lighter than
conventional
steel. As well as
reducing fuel consumption, it
offers positive environmental
benefits.
Approximately 85 % of all com-
ponents can already be recycled
using today’s technology. This
proportion is set to increase as
* Not featured in markets with leaded fuel.The new Cayman and the Cayman S |
Environment
new thermal methods are
introduced. To simplify recycling,
all synthetic components are
clearly labelled in accordance
with the relevant standards.
Both Cayman models are entirely
free of CFCs and components
manufactured with the aid of
these chemicals. Water-based
paints are used throughout each
car, thereby reducing the need
for chemical solvents during the
production process.
Servicing.
Longer service intervals are not
only more convenient for you, they
are also better for the environment.
With the new Cayman and
Cayman S, we have achieved
very modest servicing
requirements: engine oil every
20,000 miles (or two years),
oil filter every 20,000 miles, air
filter every 40,000 miles, spark
plugs every 60,000 miles (or
four years), and brake fluid every
two years.
In addition to the obvious
environmental benefits, the
advantage for you is two-fold: a
lower cost of ownership throughout
the life of the car, and more time
spent on the road. Based on
mileage alone, the new Cayman
models require just three stops
for servicing every 60,000 miles,
or one service every two years.
