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.

Porsche Active Suspension
Management (PASM).
PASM is an electronic damping
control system. Available on
both Cayman models, it offers
continuous adjustment of
individual damping forces based
on current road conditions and
driving style. Agility and driving
pleasure are significantly
enhanced while retaining the
car’s natural ride quality. Equipped
with PASM, the car rides 10 mm
lower than with the standard
steel-sprung suspension.
The driver can choose one of
two setup modes, ‘Normal’ or
‘Sport’. While the first is a blend
of performance and comfort, the
‘Sport’ setup ratings are generally
much firmer, enabling greater
agility on the racetrack. In either
mode, the system responds to
changing loads by automatically
applying the optimum damping
rate on each individual wheel.
The rates are selected from a
range of map options which are
specially adapted to the unique
dynamics of the Cayman and
Cayman S.
The movement of the body is
continuously monitored under
acceleration, braking and cornering
manoeuvres, as well as on poor
road surfaces. Other sensors
provide additional information on
lateral acceleration, steering
angle, brake pressure and engine
torque. A dedicated control unitprovides real-time analysis and
damper adjustment as defined
for the respective setup mode
(‘Normal’ or ‘Sport’). The result:
greater stability and more
consistent occupant comfort.
If, when ‘Sport’ mode is selected,
the quality of road surface drops
below a certain threshold, the
system immediately switches
to
a softer rating and restores
the car’s traction and grip.
When the road surface improves,
PASM returns to the original,
harder ratings. The system
remains active in ‘Normal’ mode,
too, automatically switching to a
harder setup if the car is driven
more assertively. As the dampers
become stiffer, the car becomes
more stable and driver control is
improved.

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.

safety feature is Porsche Stability
Management (PSM – see page 64).

The new Cayman and the Cayman S |Safety
Driver and passenger airbags.
Both full-size airbags at the
front of the car have a two-stage
inflation capability, in which
deployment is dependent on the
nature and force of the accident.
In a low-speed crash, the airbag
is only partially inflated, thereby
minimising occupant discomfort.
Anti-theft protection.
Both Cayman models have an
engine immobiliser with in-key
transponder. In addition, the
Cayman S has a comprehensive
alarm system with contact-
sensitive exterior protection.
The alarm is activated or
deactivated using the standard
key remote when locking or
unlocking the car. Radar-based
interior surveillance is also
available as an option. approximately 8 litres, ensuring
maximum protection over the
entire seat adjustment range.
The passenger cell is shielded
by side-impact protection beams
in each of the doors.
Other standard safety features
include integral head restraints,
an energy-absorbing steering
column, three-point seat belts
with pre-tensioners and force
limiters, energy-absorbing
structures in the dashboard area
and flame-retardant materials
throughout the interior.

sation technology provides
automatic adjustment of tone and
volume based on current road
speed and ambient noise. The
result is a noticeably clearer and
more consistent sound, with
no need for continuous manual
adjustment.
Active equalisation matches
all sound output to the unique
acoustics of the Cayman and
Cayman S. Covering the entire
frequency spectrum, it delivers
lifelike audio to both seat
positions.
The dynamic loudness function
included with the system is a
more sophisticated alternative to
conventional technologies. By
enhancing the lower frequencies
in low-volume sound, it actively
compensates for the reduced
sensitivity of the human ear at
the lower end of the range.The key system component,
BOSE
®Automotive Surround
Sound, uses independent
channels at front and rear to
create a push-button panorama
of space and sound. The sense
of depth is further enhanced
with the aid of patented BOSE
