Drive
Ignition system.
The ignition system in the Cayman
and Cayman S features static
high-voltage technology. Separate
coils on each of the plugs ensure
perfect ignition every time. With
no central coil, there is no need
for leads, which are a frequent
source of faults. All six coils are
directly controlled by the engine
management system. This
Cylinder-specific knock control.
Since temperatures tend to
vary across the engine, each
cylinder is monitored separately
for unwanted pre-ignition of the
air/fuel mix. If a risk is detected
in one or more cylinders, the
timing is adjusted on the
corresponding spark plug.
The system is effective under
all engine conditions, including
extremely heavy loads at low
rpm.
Exhaust system.
Both Cayman models have a
specially designed stainless steel
exhaust system. Gas is passed
from each bank of cylinders
through twin cross-linked silencer
units and exits the car through
a central tailpipe. A system of
four oxygen sensors – one before
and one after each of the two
pre-catalytic converters – provides
separate monitoring of the gas
composition and catalyst
performance for each cylinder
bank.
arrangement means they can
also be integrated with other
electronic-based systems. If the
optional Tiptronic S, for example,
requests smoother downshifts,
the system responds within a
fraction of a second and adjusts
the ignition timing.
Since a twin-tract layout allows a
higher rate of throughput than a
conventional exhaust, the system
also has a positive impact on
overall power and torque. It also
contributes to the distinctive
engine sound – on starting, at
idle and across the entire engine
speed range.
For even more powerful acoustics,
both cars can be equipped with
an optional sports exhaust system.
Servicing.
Regular servicing is extremely
important on any high-precision
machine. In the case of a
Porsche, it is equally important
to give you maximum enjoyment
from your car. We therefore aim
to reduce servicing requirements
and extend all service intervals.
The generator, power-steering
pump and air-conditioning
compressor are all driven by a
single, self-adjusting belt. Under
normal usage, the drive chains
for the cam and auxiliary shafts
are entirely maintenance-free.
The ignition system is also
maintenance-free, with the sole
exception of the spark plugs
(60,000 miles). The engine oil
interval is 20,000 miles, while
hydraulic tappets provide
automatic clearance adjustment
on each of the 24 valves.
In short: when we design a car
for the road, that’s where we
intend it to stay.Exhaust system

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.
· 66 ·Porsche Side Impact Protection (POSIP)
Vehicle tracking system.
An optional preparation is
available for both Cayman models
enabling future installation of a
vehicle tracking system obtainable
from Porsche Tequipment. The
system can be used to locate a
stolen vehicle across most of the
countries of Europe. Note:
package comprises special wiring
loom and higher capacity battery.
Child seats.
The passenger’s seat is also
designed to carry an ISOFIX-
compatible child seat. The
necessary preparation – including
airbag deactivation – is available
from Porsche Tequipment. You
will also find a comprehensive
range of Porsche child seats.
Porsche Side Impact Protection
(POSIP).
Both Cayman models are equipped
with Porsche Side Impact Protection
(POSIP) as standard. This
comprehensive package provides
effective protection for the head
and upper body area. Each seat
has two side airbags featuring
hybrid gas generant technology.
A thorax airbag is located in the
side of the seat backrest, while
a head airbag deploys upwards
from the door. All four airbags
have an individual volume ofCayman and Cayman S
