VarioCam Plus
To improve throt tle response
during the warm -up phase,
VarioCam Plus selects high valve
lif ts with retarded valve timing.
In the middle and low load ranges,
low valve lif ts with advanced
timing reduce fuel consumption
and exhaust emissions. High valve
lif ts generate high torque and
maximum output.Two-stage resonance
intake manifold.
The intake manifold with
double-flow distributor pipe has
an adjustable flap that closes and
opens at defined engine speeds.
As a result of a t wo -stage
resonance ef fect, the air mass in
the intake manifold begins to
oscillate, which in turn generates
a turbocharging ef fect and
optimises induction. These t wo
ef fects combine to produce
higher torque at low engine
speeds, a flat ter torque curve and
increased power output at high
engine speeds, while the acoustic
properties of the system are
second to none. A sound that is
typically Porsche.
VarioCam Plus.
VarioCam Plus combines variable
valve timing with t wo -stage lift
on the inlet side. This results in
smoother running, bet ter fuel
economy and lower exhaust

emissions. As well as greater top-
end power and low- end torque. This two-in-one engine concept
seamlessly adapts in response

to driver input. The result: instant
acceleration and extremely
smooth running.
The variation in intake timing
is steplessly controlled by means
of an electrohydraulic rotary
vane adjuster at the head of the
corresponding camshaf t.

Transmission.
Cayman S
This double clutch provides an
alternating, non-positive connection
bet ween the t wo half gearboxes
and the engine by means of t wo
separate input shafts (input shaft
1 is nested inside the hollowed-out
input shaft 2).
The flow of power from the engine
is only ever transmit ted through
one half gearbox and one clutch
at a time, while the next gear is preselected in the second half
gearbox. During a gear change,
therefore, a conventional shif t no
longer takes place. Instead, one
clutch simply opens and the other
closes at the same time. Gear
changes can therefore take place
within milliseconds.
Clutch 1 controls the first half
gearbox, which contains the

odd gears (1, 3, 5, 7) and reverse.
Clutch 2 controls the second,
which contains the even gears
(2, 4, 6).
Porsche Doppelkupplung (PDK).
The optional Porsche Doppel -
kupplung (PDK), with both manual
gearshif t and an automatic mode,
enables smooth gear changes
with no interruption in the flow of
power. This results in significantly
faster acceleration and lower
fuel consumption, without having
to sacrifice the ease of automatic
transmission. In total, PDK has seven gears

at its disposal. Gears 1 to 6 have
a sports ratio and top speed is
reached in 6th gear. The 7th gear
has a long ratio and helps to
reduce fuel consumption even
f u rt h e r.
PDK is essentially t wo half gear -
boxes in one and thus requires
t wo clutches – designed as a
double wet clutch transmission.

in detail.
The crankshaf t transmits engine
torque to the dual-mass fly wheel
which is then channelled through
the clutch housing and onto the
multi-plate clutches, or to be more
precise, the outer disc carrier.
Under oil pressure, clutch 1 closes
and forms a frictional connection rapid gearshif ts with no
interruption in the flow of power,
which result in a considerably
faster rate of acceleration for the
same rate of fuel consumption.
The advantage over a fully
automatic transmission is the

perceptible increase in driving
dynamics – with a similar level of
comfort, and a distinct reduction
in fuel consumption.
with input shaft 1. The torque is
now transmit ted through the
dif ferential to the rear axle.
At this stage, PDK has already
preselected the next gear.
Engine torque is already acting
on the other outer disc carrier
and, in response to a gear change
signal, the overlap shift is

initiated, i.e. as clutch 1 opens,
clutch 2 closes. The non-positive
connection with input shaf t 2 The compact dimensions of the
gearbox reduce rotational masses
which means that the engine
response is more direct and the
system is more light weight.
This, along with the long-ratio 7th
gear, helps to achieve reduced
fuel consumption and emission
figures comparable with those
of a manual gearbox. With the

– provides important information
at a glance. In the centre is the
analogue rev counter with digital
speedometer and a customisable

Steering wheels.
The Cayman models feature as
standard a three-spoke sports
steering wheel with full-size airbag.
The steering wheel is adjustable
for height and reach and the
rim is in smooth -finish leather.
As an option, you can specif y a
three-spoke multifunction steering
wheel in leather with integrated

Top marks for cleanliness.
1) Not in markets with leaded fuel.
In short, the Cayman is not only
extremely sport y, it is also very
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.
The stereo Lambda control
circuitry controls and monitors
each cylinder bank separately,
while another Lambda sensor
on each cylinder bank monitors
pollutant conversion in the respec -
tive cataly tic converter (p. 44).
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. In relation to
power output (g / km per hp),
Porsche is already among those
manufacturers achieving the
lowest CO
2 emissions. This has
been achieved through an ef ficient
drive concept (DFI), light weight
construction, optimum aerody -
namics and low rolling resistance. This high level of environmental
responsibilit y is clearly demon
-
strated by our approach to
environmental management at the
Porsche development centre in
Weissach. Here, all technological
developments are carried out
with environmental protection in
mind. The goal? Pure perform -
ance – but not at the expense of
the environment. A goal achieved
by the Cayman models.
Exhaust emission control.
Both engines comply with stringent
emission standards, including Euro 5
in Europe and LEV II/ ULEV in
the USA. Vehicles manufactured
by Porsche demonstrate that even
high -performance sportscars
can achieve moderate emission
values in their respective category.

Noise.
The Cayman models comply with
all applicable noise regulations
without any form of engine encap-
sulation. To achieve this, noises
are eliminated at source. Engine
parts are stif f, moving parts are
light weight and tolerances are
kept to a minimum. Large-volume
silencers and resonators in the
air intake system minimise noise
further. For the entire service life
of the vehicle.
Servicing.
Long service intervals of fer
clear advantages. For you: lower
costs and saved time. For the
environment: the use of fewer
consumables and replacement
parts. For full details of service
intervals, please refer to the
separate price list.
Fuel economy and recycling.
At Porsche, a fundamental aspect
of design is intelligent light weight
construction. For both economical
and ecological reasons. This
forms the basis for low fuel con -
sumption values in conjunction
with outstanding performance.
It is economical thanks to the
high proportion of aluminium cast
alloys, plastics and super high-
strength sheet steel used. This
is substantially lighter and more
stable than conventional steel. In
the Cayman models approximately
20 % of components are made
from light weight alloys. We use
only innovative and environmen -
tally friendly components,
and each material is labelled to
facilitate its separation for
recycling. Recycled plastics are
used where they meet exacting
technical requirements. In all, the
Cayman models are approximately
95 % recyclable. In addition, Porsche uses only
environmentally friendly water-
based paints. The Cayman is
absolutely free of asbestos, CFCs
and components manufactured
using CFCs. This is because,

here at Porsche, environmental
protection does not begin at
the end of a vehicle’s life. It starts
at the planning and development
stage.
Fuel.
The Cayman models are already
designed to operate on fuels with
an ethanol content of up to 10 %.
Ethanol has a positive impact on
the CO
2 balance since the plants
cultivated for the production of
this biofuel also absorb CO
2 from
the atmosphere.
The active carbon filter and
a special coating on the fuel tank
reduce the amount of hydrocar -
bons released from the fuel
system. All fuel lines are made of
aluminium, while vapour- carrying
lines are made from multi-layered
plastic.
