resonance intake manifold.
The resonance effect, where the air mass
inside the intake manifold is caused to
oscillate, is used to improve air induction
and, in turn, to optimise the formation
of the fuel/air mixture. In the Cayman S,
the manifold is also equipped with a
switchable resonance valve.
The results are high torque, a uniform
torque curve and high power output.

The sound produced is characteristically
resonant and deep.
Direct fuel injection (DFI).
Direct fuel injection (DFI) is featured as
standard in both Cayman models. Multi-
hole injectors deliver fuel directly into the
combustion chamber with millisecond
precision. The injection pattern has been
optimised for torque, power output, fuel
consumption and emissions. Combustion
is even more effective as a result.
With direct injection, the engine manage -
ment system regulates injection timing
individually for each cylinder as well as
the injection rate for each cylinder bank.
This optimises the combustion process
and therefore fuel economy. Depending on the engine operating con
-
dition, multiple fuel injections take place
so that the cataly tic converter reaches
normal operating temperature sooner
after a cold start and a greater top-end
torque can be achieved.
DFI improves the internal cooling of the
combustion chamber by having the mix -
ture prepared directly in the cylinder. This
allows for a higher compression ratio,
which helps to deliver greater power out -
put at the same time as enhanced engine
efficiency. Injection is regulated by the
electronic engine management system
and emissions are monitored by the
stereo Lambda sensors, thus helping to
protect the environment.

2 emissions and efficiency class, please refer to page 131.

Thermal management.
The intelligent thermal management
system in the Cayman models regulates
the temperature in the engine and gear -
box
to reduce friction losses that occur
during the warm-up phase.

Thanks to the purposeful control of heat
flow and on-demand, gradual activation
of the various cooling circuits, the engine
and gearbox warm up to normal operat -
ing temperature more rapidly. The result -
ing reduction in friction also reduces fuel
consumption and CO
2 emissions. During
sporty driving, thermal management also
acts to reduce temperatures so as to
maintain a high degree of performance. Our cross-flow cooling system, as used

in motorsport, supplies each engine cylin -
der uniformly with coolant, which protects
all valves against thermal overload and,
therefore, premature wear. This improves
combustion and keeps emissions, fuel con -
sumption and noise comparatively low.
exhaust system.
In the new Cayman models, each cylinder
bank has its own stainless-steel exhaust
tract. Downstream of their respective rear
silencer, the tracts converge into a con -
necting tube and a single (Cayman) or t win
(Cayman S) tailpipe. The stereo Lambda
control circuitr y

controls and monitors each cylinder bank
separately. For each
exhaust tract, four
corresponding oxygen sensors regulate
the composition of the exhaust gas and
monitor the performance of the catalytic
converters. The separate
tracts enable
the exhaust gas to flow more
f re e l y. T h e
resulting reduction in pressure loss has
a positive impact on power output, torque
and the unmistakable engine sound.
Available as an option for the new Cayman
models is the sports exhaust system*
including sports tailpipe. It produces an

even more resonant Porsche sound.

Strong relationships need sincerity,
common goals and the abilit y to over-
come difficult situations in unison.
The chassis of the new Cayman models
develops a strong bond with the road. It
is specifically matched to the high power
output of the respective engine. A xle
components are made predominantly of

aluminium, which helps to keep the weight
of the vehicle and its unsprung masses
low. The results are impressive driving
dynamics with practically zero pitch and
roll, high levels of comfort and safet y and
lower fuel consumption. The track of the new Cayman models has
been widened and the wheelbase has

been extended by 60 mm compared with
that of the previous model. This improves
stabilit y. The new independent suspension
features light weight spring-strut axles
with longitudinal and transverse links. The
cross member at the front axle has been
refined for optimum stiffness and robust -
ness. How does this benefit you? Greater
directional stability, sharper steering preci -
sion and sportier handling.
Porsche active Suspension management
(PaSm ).
Optional PASM, the electronic damping
control system, actively and continuously
regulates the damping force for each
wheel according to the road conditions
and driving st yle. In addition, the suspen -
sion is 10 mm lower than that of the
st a n d a rd s e t u p .
The system is always active in the back-
ground, ready to assist you automatically
without you having to switch it on. Never -
theless, t wo modes are available at the
push of a but ton so that you can adapt
handling to suit your preferred driving
st yle: ‘Normal’ which is a blend of perfor-
mance and comfort, and ‘Sport ’ where
the setup is much firmer. Depending on
the mode selected, therefore, PASM can
be sportier and more comfortable than
the standard chassis. The PASM control
unit evaluates the driving conditions and modifies the damping force on each of
the wheels optimally in accordance with
the selected mode.
Sensors record all wheel and body move
-
ments. This enables intelligent adaptation
of damper stiffness for the selected
mode, optimising contact between each
individual t yre and the road for even less
roll and pitch.

Porsche Stability management (PSm).
Enhanced Porsche Stability Management
(PSM) is fit ted as standard. This system
automatically maintains stability and trac -
tion even at the limits of dynamic driving
performance. Sensors continuously moni -
tor the direction, speed, yaw velocit y and
lateral acceleration of the car. Using this
information, PSM is able 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 in order to restore
stability.
Under acceleration on wet or low-grip road
surfaces, PSM improves traction – as well
as agilit y, control and safet y – using the
automatic brake differential (ABD) and
antislip regulation (ASR). Integrated ABS

is designed to minimise braking distances.
If you prefer an ever sportier drive, PSM
can be switched off. For your safet y,
however, PSM remains set to intervene if
the vehicle is braked and ABS assistance
is required.
Also included with PSM are engine drag
torque control (EDC), precharging of the
brake system and brake assist. If you
suddenly release the accelerator pedal
,
PSM automatically prepares for your next
action: the braking system is precharged
so that the brake pads are already in light

contact with the brake discs. Maximum
braking power is therefore achieved
much sooner. Brake assist detects a
panic braking situation and generates

the brake pressure required for maximum
deceleration.
PSM increases driving stabilit y and safet y
as well as the agilit y you have come to
expect from a Porsche.

a irbags.
To protect the driver and passenger,
the new Cayman models are equipped
as standard with full -size airbags, which
are inflated in t wo stages depending on
the severit y and t ype of accident (e.g. frontal or offset frontal). In less serious
accidents, the airbags are only partially
inflated, thereby minimising discomfort

to the occupants. In addition to the central airbag control
unit on the transmission tunnel, a pair

of impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated far sooner and
with considerably greater accuracy.

manufacturers are among those asking
themselves how they can contribute to

environmental protection. Our answer
has long been the same: Intelligent Per -
formance – a combination of high power
output and high efficiency.
In recent years, Porsche has managed to
reduce fuel consumption across all model
ranges by a double-digit percentage com -
pared with the respective previous model,
even though performance has been in -
creased in every generation. This is made
possible by an ef ficient drive concept,
including direct fuel injection (DFI) and
VarioCam Plus, a lightweight construc -
tion, optimised aerodynamics and low
rolling resistance.
The environmental management team
at the Porsche Development Centre in
Weissach demonstrates a high level of
environmental responsibility. Here, tech -
nological developments are carried out
with environmental protection in mind.
The goal is to enhance performance –
but preferably not at the expense of the
environment. We achieve this goal with

by the new Cayman.

environment.
e mission control.
Vehicles manufactured by Porsche dem-
onstrate that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emission
val
ues in their respective category.
This is accomplished by the use of fuel-
ef ficient technologies such as auto start /
stop, thermal management, electrical
system recuperation, direct fuel injection,
VarioCam Plus and, in conjunction with
optional PDK, coasting mode.
The newly developed cataly tic converters
also provide ef ficient emission control,
while the stereo Lambda control circuitr y
manages and monitors each cylinder
bank separately. For each exhaust tract,
oxygen sensors, together with the engine
electronics and injectors, regulate the
composition of the exhaust gas, while
another Lambda sensor on each cylinder
bank monitors pollutant conversion in
the respective cataly tic converter.

Cruise control.
Cruise control is available as an option for
the new Cayman models. This automatic
speed controller for the 30 to 240 km/ h
(18–149 mph) speed range is operated
by a switch on a separate control stalk on
the steering
column. The advantages
are clear. Not only can cruise control be
used as a
means of staying within the
speed limit, it also helps you to save fuel
by maintaining
a constant speed.
adaptive cruise control including
Porsche a ctive Safe (P aS).
Also available as an option is the en -
hanced version of cruise control, which
regulates the speed of your vehicle in
line with the speed of the vehicle in
front. A radar sensor inside the front
centre air intake scans the road ahead
up to a distance of 200 m. Imagine
you’ve selected a cruising speed but
have begun to gain on the vehicle in

front because it is driving more slowly –
this is detected by the radar sensor.
The system now reduces the speed of
your vehicle by restricting throt tle or by
gently applying the brakes until your
chosen distance from the vehicle in front
is maintained. If the vehicle ahead slows
further, adaptive cruise control will decel-
erate your vehicle accordingly – even
down to a halt.
For increased safet y, the system also
readies the brakes whenever it detects
that the distance from the vehicle is
decreasing. However, the driver should
be prepared to intervene manually if
heavier braking is required.
As soon as the road ahead clears, your
vehicle will accelerate back up to the
cruising speed originally set. Porsche
Active Safe (PAS) issues an audible and a
visual warning if the system detects that
your vehicle is approaching the vehicle in
front too quickly. This is accompanied by
a brief application of brake force and,
where necessary, the initiation of targeted
braking. During this process, any braking
by the driver is boosted to achieve the
maximum braking force that the system

is able to provide.
Park assist.
Optional Park Assist is activated the mo -
ment you select reverse gear. An audible
signal gives a warning if you reverse too
close to an obstacle.
An enhanced version of Park Assist pro -
vides monitoring of the area to the front
of the vehicle. Ultrasonic sensors are
neatly integrated in the front and rear

aprons. The audible alert is supplemented
by a visual warning in the central display
screen of the CDR audio system or op -
tional PCM showing a graphical represen -
tation of the vehicle from overhead.
