Integrated dry-sump
lubrication.
This proprietary Porsche
technology ensures consistent
lubrication in even the most
extreme high-speed corners.
Oil is extracted from each of the
cylinder heads by a dedicated
scavenge pump. The oil return
system features narrow-section
lines which de-foam the oil before
it is collected in the integral sump.
A third pump then feeds the oil
back to the lubrication points and
the cycle begins once more. A
stable oil pressure is maintained
throughout the engine, even
during racetrack use.
Oil-level indicator.
Both Cayman models have an
electronic oil-level indicator as
part of the on-board computer
system. The reading is so precise
that a conventional dipstick is not
required.
Engine cooling.
Both flat-six engines have a
cross-flow cooling system with
all coolant channels cast in the
block. With no external hoses
or pipework involved, the system
is much more secure than
conventional designs.
Coolant is supplied separately
to each individual cylinder, so
it never arrives pre-warmed. As
well as maintaining a consistent
engine temperature, this means
the valves are much less
susceptible to wear. Important
benefits include greater engine
reliability, less risk of knocking,
better fuel economy, lower
emissions and reduced mechanical
noise.
Engine management system
with electronic throttle.
The Motronic ME7.8 engine
management system is the
primary source of control for
all engine-related systems and
processes, e.g., ignition and
fuel supply. It is an essential
prerequisite for enhanced
performance in all operating
conditions. The electronic throttle
is not only more precise, it can
modulate the volume of incoming
air to compensate for sudden load
transfer (e.g., when lifting off the
throttle before braking). Electronic
engine management ensures
better power delivery from a
standing start and a smoother rev-
limiter action. It also coordinates
the various sub-systems within the

Tiptronic S.
Both Cayman models are available
with five-speed Tiptronic S as
optional equipment. This versatile
system combines an automatic
transmission with the option of
manual gearshifts.
For manual control, simply slot
the gear selector into the manual
gate and use the gearshift controls
on the steering wheel. Press up
to change up, and down to change
down. Gearshifts are performed
in around 0.2 seconds with
virtually no interruption in drive.
The action is comparable with
that of a manual gearbox.
Switch to automatic, and you can
still change gear by hand using
the rocker controls on the steering
wheel. This race-derived function
is particularly useful during
overtaking manoeuvres. If there
is no manual input for a period
of eight seconds, the system will
revert to automatic mode. The
drive position and gear selection
are displayed at all times on a
dedicated cockpit display.
In automatic mode, Tiptronic S
can choose from a range of
gearshift points for each individual
gear. The standard gearshift
pattern, designed for maximum
fuel economy, can be steplessly
varied up to a dedicated ‘Sport’
configuration for optimum high-
performance driving. Each
gearshift point is automatically
selected based on current road
conditions and driving style. Within
a short space of time, you’ll
develop a feel for the system and
begin to influence gearshifts using
the throttle alone. The benefits
of Tiptronic S are particularly
apparent when exploring the car’s
performance. Even in automatic,
the rapid gearshift action
enhances the agility of the car.

Manual gearbox with
dual-mass flywheel.
Both the Cayman and Cayman S
are specifically designed for a more
immediate driving experience. A
crucial element within that concept
is the standard manual gearbox.

ent. The

mechanical noise and thus greater
focus on the natural sound of the
engine. The flywheel is mated to
a hydraulically operated clutch,
while the final drive ratio has been
carefully selected for optimum
sports performance. The gearshift
mechanism is cable operated
so as to insulate the lever against
vibration from the engine and
gearbox.
Other useful functions include a
warm-up programme, automatic
selection of the ‘Sport’ gearshift
pattern by means of rapid throttle
inputs, gearshift suppression
during cornering manoeuvres,
automatic downshifts under heavy
braking, an incline sensor
(improves uphill acceleration and
downhill engine braking), a nd
automatic upshifts when traction
is threatened under braking in
the wet.
If the optional Sport Chrono
Package is enabled, the gearshift
action is even more direct and
responsive. If you happen to be
driving in manual mode, automatic

types have a short-throw action
and a balanced spread of ratios

PersonalisationWhen we began designing the
Cayman model range, there was
one thing we couldn’t include:
your own personal touch. To help
you add that vital ingredient,
we’ve prepared a comprehensiverange of options. Together, they
offer enormous scope for
personalising your Porsche. You
can use them to express your
individuality and style in every
area of the car. From colour
combinations and interior
materials to a custom-engineered
sound system. Whatever you
choose to include in your
specification, the result is
uniquely yours.
