6,000 rpm. From a standing start,
the Cayman accelerates to
62 mph (100 km/ h) in 5.8 seconds.
With the optional Porsche
Doppelkupplung (PDK), this sprint
takes just 5.7 seconds. Top
speed is 165 mph (265 km/ h)
in conjunction with the manual
gearbox. Equally impressive, with the CDR-30 audio system

with 5-inch display. An integrated
six- disc CD autochanger is
available as an option.
The Cayman has found its way.
Its own? Without doubt.
The Cayman is the driving force
behind precisely one at titude:

the absolute conviction to remain
true to oneself. No middle roads.
No compromises. No nonsense.
One of the features that exempli -
fies this at titude is the mid- engine
layout, which ensures a low centre however, is the 10

This means, it has been possible
to reduce fuel consumption by
up to 15 % and CO
2 emissions
by up to 16 %, depending on the
t ype of gearbox.
To accept no compromises,

to make conscious decisions, to
be governed by nothing other
than one’s own free will, and to
have a clear point of view. A
highly promising way to build a
sportscar. For us, it ’s the only
w ay. The Cayman S reaches 62 mph
(100 km/ h) in just 5.2 seconds.
Top speed isn’t reached until

172 mph (277 km/ h). Porsche
Doppelkupplung (PDK, p. 48)
is available as an option.
The fastest rate of acceleration
of 4.9 seconds is achieved
in conjunction with the optional
Sport Chrono Package.
In addition to having a higher
power output, the Cayman S
also dif fers from the Cayman in
This philosophy was also the

basis for the development of the
mid-mounted engine with a
3.4-litre capacit y and direct fuel
injection (DFI, p. 34). The engine
delivers a power output of
235 kW (320 hp) at 7,200 rpm,
and a maximum torque of 370 Nm its appearance. It has a front
spoiler painted in the vehicle’s
exterior colour, and t win

tailpipes in stainless steel. The
sound? Distinctive. In keeping
with the rest of the Cayman S.
But so much power also needs
to be tamed. This is the task of
the enlarged brake system with
four-piston aluminium monobloc
fixed calipers in a striking red
painted finish. To deliver the increased power
output to the road, the Cayman S
is fit ted with 18-inch Cayman S II
wheels. Their design exudes pure
dynamism – as befits the model’s
overall look.
In summary, the Cayman S

is more than just a sportscar.
It ’s a Porsche.
It takes no prisoners,
except for your free will.

take place, depending
on the driving st yle. DFI improves
the internal cooling of the combus -
tion chamber by having the mixture

Direct fuel injection (DFI).
The engine of the Cayman S

has direct fuel injection (DFI).
With millisecond precision, fuel is
injected at up to 120 bar directly
into the combustion chamber by prepared directly in the cylinder.
This allows for a higher compres

sion ratio (12.5 : 1) which helps
to deliver more output along with
enhanced engine ef ficiency.
Depending on the t ype of gear -
box, it has been possible to reduce
means of electromagnetically
actuated injection valves.
The spray and cone angles have
been optimised for torque,

power output, fuel consumption
and emissions by enabling a
fuel consumption by up to
15 % and CO

16 %. Injection is regulated by the
electronic engine management
system. The exhaust gas cleaning
system ensures that emissions
remain well below even the strict
limits of the Euro 5 emission

Integrated dry-sump lubrication.
The purpose of integrated dry-sump
lubrication is to guarantee a
reliable oil supply while reducing
engine temperatures, even in
sportily driven cars. The oil reser -
voir is located inside the engine.
Four oil pumps remove the oil For the engine, these detailed
solutions mean a consistent

supply of oil regardless of gravita -
tional loads, even in the most
demanding track conditions.
Lightweight construction.
Both Cayman models are
equipped with alloy engines. The
ingenious design, down to the
finest detail, keeps the weight of
the engines low and therefore
reduces fuel consumption. One of
the ways in which this light weight from the cylinder heads directly
into the oil sump. A fif th pump in
the oil sump directly supplies the
lubricating points in the engine.
To reduce power loss and increase
efficiency, an electronically

controlled oil pump supplies the
lubricating points inside the

by fully integrating the camshaf t
bearings into the cylinder heads.

This means that the oil pump
does not work so hard when there
is less demand for lubrication.
The benefits of this oil supply

system include optimum efficiency

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, supplies
each engine cylinder uniformly
with coolant. Valves are thus
protected against overload and
premature wear, which minimises
the engine’s tendency to knock
and optimises emissions and fuel
consumption.

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 reduced fuel
consumption and emissions.
Another important function of the
system is cylinder-specific knock
control. Since the six cylinders

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.

circuitry controls and monitors
each cylinder bank separately.

For each exhaust tract, four corre -
sponding oxygen sensors regulate
the composition of the exhaust
gas and monitor the conversion
of pollutants in the cataly tic con -
verters.
A sports exhaust system – for a
more resonant sound – is
available as an option for

each of the Cayman models.
Ignition system.
The ignition system is designed
for static high -voltage distribution.
Individual ignition coils on each
of the spark plugs ensure perfect
ignition every time. The individual
ignition coils are controlled
directly by the engine electronics.
Servicing.
It is a good idea to have your
vehicle serviced regularly, but it
makes just as much sense to keep
the time bet ween maintenance
services as long as possible. Why?
Because a Porsche belongs on
the road, and not in the workshop.
The alternator, power-steering
pump and the air- conditioning
Exhaust system.
The exhaust system – with t win
tailpipes on the Cayman S – is
made of stainless steel. Until it
converges in the connecting tube,
the exhaust gas is channelled
through t wo separate tracts and,
thanks to separate exhaust gas
cleaning systems, the exhaust
gas can flow more freely – for
increased power and torque.
The stereo Lambda control
compressor are all driven by a
single self-adjusting belt. Hydraulic

valve clearance compensation
makes valve clearance adjustment
unnecessary. The drive chains
on the camshaf ts do not normally
require servicing. With the sole
exception of the spark plugs, the
ignition system is also mainte -
nance -free.
Put simply, we don’t expect to
see your Porsche too often.
