2010 PORSCHE CAYMAN S engine oil

is achieved at 4,750 rpm.
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.

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
combined with a reduction in

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.
Engine management system
with E-Gas.
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

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.
