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

higher torque at low rpm, a flatter
torque curve, and greater top-end
power. It also brings an additional
dimension to the unique engine
sound.VarioCam Plus.
VarioCam Plus combines variable
valve timing with two-stage lift
on the inlet side. The resulting
benefits include greater power and
torque at all engine speeds, as
well as smoother running, better
fuel economy and fewer exhaust
emissions.
Essentially, the system creates
two engines out of one, switching
seamlessly between them as
driver inputs change. All operations
are centrally controlled by
the Motronic ME7.8 engine
management system. The result:
rapid acceleration and balanced
running characteristics.
The two-stage valve lift mechanism
on the inlet side incorporates
a series of electro-hydraulically
switchable tappets. Each of
the 12 tappets consists of two
concentric lifters which can be
locked together by means of a
pin when required by the engine
management system. When the
tappets are locked, the outermost
ring – which is driven by two large-
profile cams – is in direct contact
Two-stage resonance intake
manifold.
The intake manifold has a twin-flow
pipe with two-stage valve which
opens and closes at predefined
engine speeds. An additional
‘resonance’ pipe connecting the
twin plenum chambers is used
to alter the geometry within the
manifold. The resulting vibration in
the incoming air helps to maximise
cylinder charging and create the
optimum air/fuel mix. The results:
with the valve. When the pin is
removed, the innermost lifter –
operated by a smaller cam lobe –
has sole influence over the
amount of valve lift. The timing of
each valve is steplessly controlled
by means of an electro-hydraulic
rotary vane adjuster at the head
of each inlet camshaft.
To improve responsiveness when
starting from cold, VarioCam Plus
will raise the amount of lift and
retard the timing of the valves.
At medium revs and minimal load,
the valve lift is lowered and timing
advanced to help minimise fuel
consumption and emissions.
To achieve maximum power and
torque, the lift is raised and the
timing advanced.

a more natural and involving
response to lateral and longitudinal
forces. Cornering agility is
considerably enhanced, with
greater scope for oversteer on
turn-in and exit. This additional
manoeuvrability is particularly
apparent in lower-speed sequences
and bends.
For maximum dexterity, PSM can
be set to standby while the car is
still in ‘Sport’ mode. PSM simply
monitors the forces acting on the
car and will only intervene in the
most critical scenarios, e.g., when
ABS assistance is required on both
front brakes.
To help you quantify this increase
in performance, the Sport Chrono
Package includes a compact timer
with swivel display which is
centrally located on the dashboard.
Functions are accessed via the
control stalk for the on-board
computer. Analogue dials measure
hours, minutes and seconds, while
a separate digital field displays
whole seconds, tenths and one
hundredths of a second. The digital
field runs in parallel with a second
digital display which is conveniently
located in the instrument cluster.
Sport Chrono Package Plus.
This enhanced Sport Chrono option
is available in conjunction with the
optional Porsche Communication
Management (PCM – see page 86).
It offers all the same functions as
the Sport Chrono Package as well
as some additional information
options and features.

Lap or journey times can be
viewed, stored and analysed using
a special performance display in
PCM. The information available
includes time elapsed and
distance travelled on the current
lap, as well as the number of laps
completed and their respective
times. You can also view the
current fastest lap as well as the
remaining range till empty. Driving
times can be recorded for any
stretch of road, and benchmark
times defined. Other useful features
include a personal memory
function which is also controlled
via PCM. This can be used to store
personal preferences for a range
of systems, including daytime

rev limiter becomes harder, and
the engine dynamics become
more like those of a racing car.
While this is happening, the
optional sports exhaust system
(see page 41) and optional PASM
are also switching to ‘Sport’ mode.
The baseline damper rating is
now considerably firmer, enabling
faster turn-in as well as better
road-holding and traction.On vehicles equipped with
optional Tiptronic S, the automatic
gearshift is noticeably more
dynamic. Upshifts and downshifts
are performed at higher revs with
a faster gearshift action. When
you lift off the throttle to slow the
car, engine braking is applied
sooner. There are no unwanted
upshifts in manual mode when
approaching the engine speed limit.

it can never suspend the laws of
physics, PSM does provide that
extra margin of safety whenever
you need it most. A key component
in PSM is a specially optimised
anti-lock braking system (ABS)
offering safer deceleration and
shorter braking distances. PSM
is also invaluable when applying
the throttle on low-grip surfaces.
Here, it uses the ABD (automatic
brake differential) and ASR
(anti-slip regulation) functions to
maintain traction and stability.
In order to retain the car’s natural
agility, PSM combines a high
trigger threshold with precision
input characteristics.
Porsche Stability
Management (PSM).
This automatic vehicle stability
control system is standard
equipment on both Cayman
models. Throughout each journey,
PSM uses a range of sensors to
monitor the direction, speed, yaw
velocity and lateral acceleration
of the car. Using this information,
it is possible 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 to restore
stability and optimum speed. WhileThe PSM threshold is raised
higher still when ‘Sport’ mode is
selected on the optional Sport
Chrono Package/Sport Chrono
Package Plus. The resulting
drive is much more involving,
particularly at speeds up to
around 70 km / h (44 mph). If
you’d rather enjoy the car
unassisted, the system can be set
to standby. When ‘Sport’ mode is
selected, PSM will only intervene
under heavy braking where both
front wheels are in danger of
locking. In ‘Normal’ mode, PSM
automatically becomes active
as soon as one of the front
wheels requires ABS assistance.The upper section of each door
features additional reinforcements
(3) which enhance the rigidity of
the car. This upper load path (4)
is used to channel energy into
the side of the car and thus
provide additional protection for
the passenger cell.
Passive safety.
Both Cayman models easily
comply with all statutory
requirements in respect of frontal,
side, diagonal, rear impact and
rollover protection.
The bodyshell structure contains
a highly resilient passenger
cell offering exceptional crash
protection. At the front of the
car, the cell is protected by a
patented system of longitudinal
and transverse members (1). In
the event of an accident, energy
is absorbed and distributed by
the front-end structure, thereby
minimising cell deformation.
Additional features include a
bulkhead cross-member (2) made
from super high-strength steel.
This element is designed to
absorb impact forces from the
longitudinal members and thus
protect both front footwells.
