It ’s always worth taking the direct route:
from stimulus to response, from resting
pulse to pounding heart, from impulse to
endorphin rush – not least when the dis-
tance to travel is less than half a metre.
The new Cayman is equipped with a com -
pletely newly developed 2.7- litre boxer
engine and the Cayman S is driven by a

3.4-litre variant, both of which are tuned
for sport y driving. Accelerator pedal in -
puts are translated directly into propul -
sion. Maximum torque is available over a
broad engine speed range. Both engines feature direct fuel injection
(DFI) and VarioCam Plus. Power is trans
-
mit ted to the wheels by a smooth
6-speed manual gearbox or the optional

7-speed Porsche Doppelkupplung (PDK).
Exemplary efficiency is achieved by means
of sophisticated technologies. As stand ard,
these include the auto start/stop function,
electromechanical power steering, elec -
trical system recuperation and intelligent
thermal management. The result, depend -
ing on the equipment variant, is a 16 %
reduction in CO2 emissions compared with
the previous model.

e ngineering.
Thanks to our principles of intelligent light -
weight construction, we have succeeded
in making the body stiffer and simultan-
eously lighter. The chassis has been com -
pletely revised. For enhanced dynamic per -
formance and increased driving stability
when the car is pushed to the limit, both
models are equipped with Porsche Stability
Management (PSM). Enhanced Porsche
Active Suspension Management (PASM)
is available as an option and includes a
ride height reduction of 10 mm. Porsche
Torque Vectoring (PT V) with rear differen -
tial lock for increased agilit y and traction
in corners is also available on request.
For fuel consumption, CO
2 emissions and efficiency class, please refer to page 131.
The optional Sport Chrono Package makes
the response and handling characteristics
of the new Cayman even sportier. For the
first time, the package now also includes
dynamic transmission mounts, which make
a perceptible contribution to handling
stabi l ity in fast corners whilst ensuring
a high degree of ride comfort.
Several years of development work and
countless draf ts later, our engineers have
realised their goal: the direct link bet ween
action and reaction. Experience the result
in the new Cayman, and let your pulse
rate be the measure of success.

Inner strength, the will to advance and a
clear point of view. These are important
prerequisites for the creation of any
sports car, and we also found them to be
precisely the right requirements for this
drivetrain.
That is why the new Cayman models are
equipped with a compact, mid-mounted
boxer engine positioned no further than
30 cm behind the driver. This unorthodox
approach has crucial strengths. A substan-
tial amount of vehicle weight is concen-
trated close to the middle of the vehicle.
The centre of gravit y is low and central and weight is distributed uniformly

bet ween the front and rear axles. The
tangible effect for you is well-balanced
handling and excellent agility, particularly
in corners.
Inner values are defined by high power
plus reduced fuel consumption and emis -
sion figures compared with the previous
model. We call it Intelligent Performance,
a philosophy that applies the engineering
principles of the racetrack to the road.
Both engines are equipped as standard
with VarioCam Plus and direct fuel injec -

technologies such as auto start /stop,
electrical system recuperation and

What can you expect from the driving
experience? Direct responses to every
burst of acceleration, dynamic handling
in every corner and the inevitable pain
of separation at the end of every drive.

e ngine management.
The electronic engine management
system ensures optimum perfect engine
performance at all times. It regulates all
engine-related functions and assemblies.
The results are optimum power output
and torque with comparatively low fuel
consumption and emissions – whatever
the driving st yle.
One example is the cylinder-specific knock
control. Since engine cylinders never all
work under exactly the same conditions,
the knock control function monitors each one separately. The ignition point is shift
-
ed individually, as and when necessary,
so as to protect the cylinders and pistons
at high engine speeds and loads. For
compliance with EU standards, the on-
board diagnostics detect any faults and
defects that may occur in the exhaust
and fuel systems and then display them
on the on-board computer. This also
helps to avoid increased pollutant emis
-
sions and unnecessary fuel consumption.
a uto start/stop function.
The auto start/stop function, which is in -
tegrated as standard in the new Cayman
models, switches off the engine when
you stop, select neutral and release
the clutch pedal. In cars with Porsche
Doppelkupplung (PDK), it is simply a
case of applying and holding the brake.
All audio and communication systems
remain switched on. The engine will

restart as soon as you operate the clutch
or, in cars with PDK, release the brake.
This fuel-saving innovation is designed

primarily for use in urban traffic. The auto start /stop function can be deac
-
tivated and reactivated using a separate
but ton on the centre console. The func -
tion is deactivated automatically under
particular circumstances, e.g. in the
event of extreme outside temperatures,
activation of the SPORT but ton or low

bat tery charge.

SP or T button.
The SPORT but ton on the centre console
is fit ted as standard. When selected,
‘Sport ’ mode is activated to provide a
greater response and enhanced driving
pleasure. The engine reacts even more
directly to the accelerator pedal, the

rev-limiter is adjusted to a harder set ting
and engine dynamics are tuned for per -
formance driving. At the same time, the
auto start /stop function is deactivated
automatically.
With optional Porsche Doppelkupplung
(PDK), the shift points are reconfigured
to offer higher and even sportier rpm bands. Shift times are reduced and gear
-
shifts become firmer and more immedi -
ate, while throttle-blip downshifts are
accompanied by an even more emotive
engine sound. Coasting mode (p. 44) is
deactivated automatically. e lectrical system recuperation.
Another efficiency-enhancing feature of
the new Cayman models is intelligent
electrical system recuperation. The vehi-
cle bat tery is recharged by the generator
predominantly under braking. Thanks
to this selective recharging, when you

request full driving power, the maximum
possible output of the engine can be
directed straight to the road because

the electrical systems are supplied main -
ly by the energy that was stored in the
battery during the braking phase.
Servicing.
In the Cayman models, the generator and
air conditioning system are driven by a
single self-adjusting belt. The drive chains
on the camshafts do not normally require
servicing. With the sole exception of the spark
plugs, the ignition system is also

maintenance-free. In short, longer service
intervals mean longer-lasting driving
pleasure.

Sport Chrono Package.
Better performance would normally be
impossible to achieve without more inten -
sive training. In the new Cayman models,
it comes at the push of a but ton. The
optional Sport Chrono Package provides
simultaneous enhancement for the chas -
sis, engine and transmission – accom -
panied by an even more emotive sound.
In addition to the performance display,
a digital and an analogue stopwatch,

the Sport Chrono Package also includes
dynamic gearbox mounts (p. 64). Another
component is the SPORT PLUS but ton.
When this is pressed, optional Porsche
Active Suspension Management (PASM)
switches to ‘Sport ’ mode for harder
damping and more direct steering and,
therefore, even more intensive road

holding.
The trigger threshold for PSM is raised.
Agilit y is perceptibly enhanced when
braking for corners with PSM, allowing
even sportier braking and exit accelera -
tion. For even greater dexterit y, PSM can
be set to standby while the car is still in
SPORT PLUS mode. For safet y, it is set
to intervene automatically only when ABS
assistance is required.
The throttle-blip function produces even
sportier gearshifts. A managed burst
of throt tle ensures smooth load changes
for increased stabilit y and makes the
gearshift process an even more engaging
experience.
In conjunction with optional PDK, the
Sport Chrono Package comes with t wo
additional functions for a sport y drive
that borders on a motorsport experience. The first is ‘Launch Control’, which is de
-
signed to produce a racing start.
The second function is the ‘motorsport-
derived gearshift strategy’. In this mode,
PDK is designed for very short shift times
and optimum shift points, while torque
boosts during gear changes provide the
maximum acceleration available. Thi
s
involving experience is further enhanced
by overrun downshifts and the throt tle-
blip function for uncompromising driving
pleasure.
An additional display in the steering wheel
and instrument cluster indicates whether
the SPORT or SPORT PLUS but tons
and, with PDK, Launch Control have been
activated. In conjunction with optional
Porsche Communication Management
(PCM), a special display enables you to

view, store and evaluate lap times or other
driving times. It shows the total driving
time, lap distance, lap number and lap
times recorded so far.

manufacturers are among those asking
themselves how they can contribute to

environmental protection. Our answer
has long been the same: Intelligent Per -
formance – a combination of high power
output and high efficiency.
In recent years, Porsche has managed to
reduce fuel consumption across all model
ranges by a double-digit percentage com -
pared with the respective previous model,
even though performance has been in -
creased in every generation. This is made
possible by an ef ficient drive concept,
including direct fuel injection (DFI) and
VarioCam Plus, a lightweight construc -
tion, optimised aerodynamics and low
rolling resistance.
The environmental management team
at the Porsche Development Centre in
Weissach demonstrates a high level of
environmental responsibility. Here, tech -
nological developments are carried out
with environmental protection in mind.
The goal is to enhance performance –
but preferably not at the expense of the
environment. We achieve this goal with
Intelligent Performance, as epitomised

by the new Cayman.

environment.
e mission control.
Vehicles manufactured by Porsche dem-
onstrate that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emission
val
ues in their respective category.
This is accomplished by the use of fuel-
ef ficient technologies such as auto start /
stop, thermal management, electrical
system recuperation, direct fuel injection,
VarioCam Plus and, in conjunction with
optional PDK, coasting mode.
The newly developed cataly tic converters
also provide ef ficient emission control,
while the stereo Lambda control circuitr y
manages and monitors each cylinder
bank separately. For each exhaust tract,
oxygen sensors, together with the engine
electronics and injectors, regulate the
composition of the exhaust gas, while
another Lambda sensor on each cylinder
bank monitors pollutant conversion in
the respective cataly tic converter.
