same conditions, they are
monitored individually by the
knock control. The ignition point
is shifted individually, as and
when necessary, to protect the
cylinders and pistons at high
engine speeds. The on -board
diagnostics, which are compliant
with European standards, ensure
timely detection of any faults
and defects that may occur in the
exhaust and fuel systems and
notif y the driver immediately. This
also prevents increased pollutant
emissions and unnecessary fuel
consumption.Engine cooling system.
Our cross-flow cooling system,
as used in motorsport, minimises
the engine’s tendency to knock
and ensures comparatively low
emissions, fuel consumption and
noise levels.
Engine management system
with E-Gas.
The electronic engine management
system ensures optimum engine
performance at all times. It regu-
lates all engine-related functions
and assemblies (see diagram).
The results: optimum performance
and torque with comparatively low
fuel consumption and emissions.
Another important function of the
system is cylinder-specific knock
control. Since the six cylinders
never all work under exactly the

Adaptive sports seat with driver memor y
Comfort seat with driver memor y Sports bucket seat Automatic climate control
fore/af t position is adjusted
manually, the backrest electrically.
Adaptive sports seats with
driver memory.
The optional adaptive sports
seats in leather combine excellent
comfort with first-rate track
performance.
Along with all the adjustment
features of the comfort seats, the
side bolsters on the seat surface
and backrest are individually
electrically adjustable, for increased
comfort on long journeys and tailor-
made lateral support through
bends or on the racetrack. The
memory function supports the
exterior mirrors and all driver’s
seat positions, apart from the side
bolsters.
Air conditioning.
Both Cayman models come
with a powerful and quiet air-
conditioning system as standard.
The optional climate control
system of fers even more uniform
and comfortable ventilation.
Cruise control.
This optional automatic speed
controller for the 30 to 240 km/ h
(19 –149 mph) speed range
is operated using a switch on a
separate control stalk on the
steering column.
Standard seats.
The standard seats with centre
upholstered in Alcantara offer a
high degree of comfort with good
lateral support and optimised
under-seat suspension. Through
bends, your seat gives you a
feeling of securit y without restric -
tion. The seats are equipped as
standard with manual height and
fore/aft adjustment and an electric
backrest adjustment, enabling
virtually every driver to find the
ideal seat position, regardless of
physical build.
Comfort seats with
driver memory.
Comfort seats with electric fore/
af t, height, backrest and lumbar
support adjustment are available
as an option. The tilt angle of the
Sports bucket seats.1)
For the ultimate sports experience,
you could opt for sports bucket
seats with a folding backrest,
integral thorax airbag and manual
fore/aft adjustment. The backrest
shell is made from glass-/carbon-
fibre-reinforced plastic and has a
st ylish carbon-weave finish. The
backrest pivots are positioned high
in the side bolsters to provide
lateral support to the pelvic region,
characteristic of a race seat. The
seat upholstery is offered in all
available leather t ypes and colours.
seat squab is also electrically
adjustable. The memory function
supports the exterior mirrors and
all seat positions on the driver’s
side. Using the control switches
in the door panel, it is possible to
restore one of t wo personalised
set tings. Additionally, you can
store a further seat position in
each of the ignition keys. As soon
as you unlock the door using
the key remote, the driver’s seat
and exterior mirrors resume their
stored position.
Sports seats.
The optional sports seats have
firmer leather upholstery than
the standard design. Higher side
bolsters on the seat squab and
backrest provide additional lateral
support. The seat height and
Seat heating and ventilation.
As an option, all compatible seats
– apart from sports bucket seats
– can be equipped with t wo -level
seat heating.
Seat ventilation for the standard
seats and comfort seats is also
available as an option (only in
conjunction with seat heating,
climate control and part or full-
leather interior). A slipstream
effect evaporates perspiration
moisture – for a comfortable

seating environment. Ventilation
intensit y can be set to one of
three levels.

1)
In an era of intensif ying debate
about global climate change and
CO
2 emissions, every automotive
manufacturer is asking itself
what it has to of fer in terms
of environmental protection. Our
answer has long been the same:
maximum ef ficiency.
Over the last 15 years, Porsche
has managed to reduce the
fuel consumption of its vehicles
by an average of 1.7 % each year.
Improvements in fuel economy
also have a beneficial impact
on CO
2 emissions. This has been
achieved through an ef ficient
drive concept (DFI), light weight
construction, optimum aerody -
namics and low rolling resistance.
The goal? Pure performance – but
not at the expense of the environ -
ment. A goal achieved by the
Cayman models.
Exhaust emission control.
Both engines comply with the Euro
5 emission standard
in Europe and
LEV II/ ULEV in
the USA. Vehicles
manufactured by Porsche demon-
strate that even
high -performance
sportscars can achieve moderate
em issio n
values in their respective
category. In short, the Cayman
is not only sport y, it is also clean.
This at tribute is achieved by
means of a t wo -stage cascade-
t ype cataly tic converter
which comprises t wo monolith
substrates on each of the t win
exhaust tracts. These specially
coated substrates contain
ultra-fine honeycomb channels in
which pollutants are converted
as exhaust gas passes through.
