Transmission.
Cayman S
This double clutch provides an
alternating, non-positive connection
bet ween the t wo half gearboxes
and the engine by means of t wo
separate input shafts (input shaft
1 is nested inside the hollowed-out
input shaft 2).
The flow of power from the engine
is only ever transmit ted through
one half gearbox and one clutch
at a time, while the next gear is preselected in the second half
gearbox. During a gear change,
therefore, a conventional shif t no
longer takes place. Instead, one
clutch simply opens and the other
closes at the same time. Gear
changes can therefore take place
within milliseconds.
Clutch 1 controls the first half
gearbox, which contains the
odd gears (1, 3, 5, 7) and reverse.
Clutch 2 controls the second,
which contains the even gears
(2, 4, 6).
Porsche Doppelkupplung (PDK).
The optional Porsche Doppel
-
kupplung (PDK), with both manual
gearshif t and an automatic mode,
enables smooth gear changes
with no interruption in the flow of
power. This results in significantly
faster acceleration and lower
fuel consumption, without having
to sacrifice the ease of automatic
transmission. In total, PDK has seven gears
at its disposal. Gears 1 to 6 have
a sports ratio and top speed is
reached in 6th gear. The 7th gear
has a long ratio and helps to
reduce fuel consumption even
f u rt h e r.
PDK is essentially t wo half gear-
boxes in one and thus requires
t wo clutches – designed as a
double wet clutch transmission.

A display on the lef t and right
steering wheel spokes tells you
whether the SPORT, SPORT PLUS
and Launch Control functions of
the optional Sport Chrono Package
are activated. Another feature
reminiscent of the world of motor-
spor t is the top centre marking
on the steering wheel rim.
Gear selector for Porsche
Doppelkupplung (PDK).
The gear selector for PDK
impresses not only with its unique
design, but above all with its
superior functionality enabling you
to change gear manually: press wheels for approximately t wo
seconds once the footbrake is
released. The vehicle is therefore
temporarily prevented from rolling
backwards. Brake pressure is
reduced if, within t wo seconds,

the steering wheel.
Six-speed manual gearbox.
Fit ted as standard in each of the
Cayman models is a six-speed
manual gearbox. The shift throw is
short and precise, the tuning is

SportDesign steering wheel.
Visually, this steering wheel is
distinguished by its high-qualit y t win-
spoke design and silver-coloured
galvanised spoke cover. The airbag
module is finished in the same
colour as the steering wheel rim.

This optional steering wheel allows
you to make motorsport-st yle gear
changes. In conjunction with the
optional PDK, the SportDesign
steering wheel features t wo alloy

Steering.
What use is a perfect suspension
setup without perfectly tuned
steering? For Porsche, this would
be inconceivable. The solution is

as much precision and immediacy
as the chassis itself and, thanks to

Wheels.
The Cayman is fit ted with
17-inch wheels as standard. The
star-shaped design expresses
sheer sportiness and allows
an eye- catching view of the brake
calipers. The Cayman S is fit ted
with large, 18-inch wheels as
standard and the turbine-like
arrangement of the spokes gives
the car an extremely powerful
look. 19 -inch wheels are available
for both models on request.
All available wheels are equipped

level. Around the straight ahead
position, such as during motorway
driving, the ratio is less direct

through tight bends and when
parking and provides a high

selection of alternative wheels,
such as the 19 -inch 911 Turbo II
wheel, is featured on page 117.
Tyre Pressure Monitoring (TPM).
The optional Tyre Pressure
Monitoring (TPM) sends warnings
to the on -board computer’s
display screen in the event of low
t yre pressure. The driver can
check the pressure in all four
t yres from the instrument cluster.

Mechanically locking rear
differential.
Are you a fan of sport y driving? In
your spare time, do you enjoy the
occasional outing on the racetrack?
Then you shouldn’t do without the
optional mechanically locking rear
differential available in conjunction
with 18-inch or 19-inch wheels.
It further enhances the traction of
the driven rear wheels on uneven
roads and when accelerating out of
tight bends, and the damping of
load-change reactions during
fast cornering is reduced. Road
holding at the limits of perform-
ance is even more impressive. The
car holds its course bet ter and so
PSM (p. 72) intervenes less often.
In other words, sheer driving
pleasure and faster lap times.
Porsche Active Suspension
Management (PASM).
The optional PASM is an electronic
damping control system. PASM
actively and continuously regulates
the damping force for each wheel
according to the road conditions
and driving st yle. In addition, the
suspension is lowered by 10 mm.
The driver can select bet ween
t wo dif ferent modes: ‘Normal’
which is a blend of performance
and comfort, and ‘Sport ’ where
the setup is much firmer.
Depending on the mode selected,
therefore, PASM is sportier or
more comfortable than the
standard chassis. The PASM
control unit evaluates the driving
conditions and modifies the
damping force on each of the
wheels in accordance with the
selected mode. Sensors monitor the movement
of the vehicle body, for example,
under heav y acceleration and
braking or on uneven roads. The
control unit tunes the dampers
to the optimum hardness for the
selected mode to reduce roll and
pitch still further and to increase
contact bet ween each individual
wheel and the road.
In ‘Sport ’ mode, the suspension
is set to a harder damper rating.
On uneven roads, PASM immedi
-
ately switches to a softer rating
within the ‘Sport ’ setup range,
thereby improving contact
bet ween the wheels and the road.
When the road surface improves,
PASM automatically reverts
to the original, harder rating.
If ‘Normal’ mode is selected and
the driver’s st yle becomes more
assertive, PASM automatically
switches to a harder rating
within the ‘Normal’ setup range.
Damping becomes harder, and
driving stabilit y and road safet y
are increased.

front wheels.
A key component of the Sport
Chrono Package is the swivel-
mounted stopwatch in the centre
of the dashboard with analogue
and digital display.
In combination with Porsche
Doppelkupplung (PDK), the Sport
Chrono Package offers t wo addi -
tional functions that are activated
by the SPORT PLUS but ton.
First, ‘Launch Control’, which
ensures you achieve the fastest
possible rate of acceleration from
a standing start – on the racetrack,
for example. ‘Launch Control’ is

operated via the SPORT PLUS
but ton with the ‘D’ or ‘M’ drive
position selected. Whilst the driver
depresses the brake pedal
with the lef t foot, the right foot
depresses the accelerator pedal
to the floor. With the accelerator
in the kickdown position, the

The shif t times are shorter, the
gear changes sportier. At low
rates of deceleration, the system
initiates a swif ter, brake-induced
downshift. In manual mode,

gear changes are faster and more
dynamic. In ‘Sport ’ mode, the
PSM system (p. 72) intervenes
later for increased longitudinal and
lateral dynamics. PSM now af fords
greater manoeuvrabilit y under
braking and exit acceleration,
especially at low speeds.
Sport Chrono Package.
Do you think driving a Porsche
should be an even more involving
experience than it is already? Your
wish is our command. On request,
we can equip your vehicle with the
Sport Chrono Package, which is
available for both of the Cayman
models. Its functions enable even
sportier tuning of the engine and
chassis and guarantee even more
driving pleasure.
Selecting the SPORT but ton
on the centre console activates ‘Sport ’ mode, which makes
throt tle response significantly
more immediate, adjusts the
rev-limiter to a harder set ting,

and tunes the engine dynamics
for performance driving.
The optional Porsche Active
Suspension Management (PASM)
also switches to ‘Sport ’ mode,
which of fers harder damping

therefore, bet ter road holding.

request for Launch mode and revs
the engine to an optimum speed
of approximately 6,500 rpm.
Engine torque increases and the
clutch closes slightly. The message
‘Launch Control’ appears on
the display on the steering wheel
for PDK. The driver now quickly
releases the brake – and prepares
for maximum acceleration.
Second, the ‘motorsport- derived
gearshif t strategy’. Using this, PDK
is geared up for maximum shif t
speed, the shortest possible shif t
times and optimum shif t points
for maximum acceleration – for
uncompromising performance.
Sport Chrono Package Plus.
On request, the optional Porsche
Communication Management
(PCM, p. 92) can be combined
with the Sport Chrono Package
Plus. In addition to the functions
of the Sport Chrono Package,
it includes a personal memory
function, which can be controlled
using PCM, and a performance
display for evaluating lap times.

that all brake components be

professionally inspected and
replaced where necessary af ter
every track event.Porsche Ceramic Composite
Brake (PCCB).
On request, we can equip your
Cayman S with a brake system
that has already had to cope
with the harshest requirements of
motorsport: the Porsche Ceramic
Composite Brake (PCCB). The
ceramic brake discs have a diam -
eter of 350 mm front and rear –
for extremely powerful braking. All the necessary ingredients are
there for a short braking distance,
even in the toughest conditions.
Moreover, safet y under braking

at high speeds is increased thanks
to the excellent fade resistance
of PCCB.
The key advantage of PCCB is that
the brake discs are approximately
50 % lighter than standard discs
of similar design and size. A factor
The brake discs are formed from

a specially treated carbon -fibre
compound that is silicated in a
high-vacuum process at approxi -
mately 1,700 °C. Not only are the
resulting discs much harder than
standard discs, they are more
resistant to heat. The low thermal
expansion of the brake discs
prevents deformation under heav y
braking. Furthermore, the ceramic
brake discs are totally resistant to that helps to reduce unsprung and
rotating masses on the vehicle.
The consequence of this is bet ter
road holding and increased
comfort, particularly on uneven
roads, as well as greater agilit y
and improved handling.
Please note that circuit racing,
trackday use and other forms
of performance driving can
significantly reduce the service life

it is automatically reactivated for
your safet y if either of the front
wheels (in ‘Sport ’ mode, both
of the front wheels) requires ABS
assistance. ABD remains perma -
nently active. Two additional
functions of PSM increase safet y
even further: precharging of the
brake system, and brake assist.
If you suddenly release the accel -
erator pedal, PSM automatically
readies the braking system. With
the braking system having been
precharged, the brake pads are
already in light contact with the
brake discs. Maximum braking
power is therefore achieved much the car. The forces exerted in a
frontal collision are transmit ted
into the side structure along a
higher load path (4), which improves
the deformation characteristics
of the passenger cell even further.
Porsche Stability Management
(PSM).
PSM, which comes as standard, is
an automatic control system that
stabilises the vehicle at the limits
of dynamic driving performance.
Sensors continuously monitor
driving direction, speed, yaw veloc-
it y and lateral acceleration. Using
this information, PSM computes the
actual direction of motion. If this
direction deviates from the desired
course, PSM initiates braking
interventions targeted at individual
wheels in order to stabilise the
vehicle.
sooner. When sudden braking is
detected, the brake assist function
applies maximum brake pressure
to all four wheels.
Passive safety:
engineered design.
The system of longitudinal and
transverse members at the front
of the vehicle (1) distributes the
Under acceleration on wet or
low-grip road surfaces, PSM
improves traction using the ABD
(automatic brake differential)
and ASR (anti-slip regulation)
functions, giving an agile
response. When ‘Sport ’ mode is
selected on the optional Sport
Chrono Packages (p. 62), the PSM
intervention threshold is raised to
enable greater driver involvement
– particularly at speeds of up to
approximately 70 km/ h (45 mph).
The integrated ABS can further
reduce the braking distance.
For an even sportier drive, PSM
can be deactivated. However, forces exerted onto the bodyshell
in the event of an impact and

minimises deformation of the
passenger cell. Our patented

body work structure with a rigid
bulkhead cross member (2) made
of ultra high-strength steel absorbs
the forces introduced into the
system of longitudinal members
which prevents deformation of the
foot well. The reinforced doors (3)
