Porsche Torque Vectoring (PTV).
This optional system for increasing
dynamic performance and stability varies
the distribution of torque to the rear
wheels and includes a mechanically lock -
ing rear differential. When the car is driven assertively into

a corner, moderate brake pressure is
applied to the inside rear wheel. Conse -
quently, an additional rotational pulse
(yaw movement) is induced around the
vehicle’s vertical axis in the direction of the turn. This results in a direct and
sport y steering action as the car enters
the corner.
At low and medium vehicle speeds, PT V
significantly increases agilit y and steering
precision. At high speeds and when

accelerating out of corners, the rear

differential lock ensures greater driving
stabilit y and traction on road surfaces
with varying grip, including the wet and
snow.
The results are remarkable stability,
optimum traction and excellent cornering
dynamics at all speeds, coupled with
precise steering and stable load transfer
characteristics through ever y t wist and
turn of your journey.

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.

Dynamic gearbox mounts.
Dynamic gearbox mounts are a component
of the optionally available Sport Chrono
Package. This electronically controlled
system minimises the oscillations and

vibrations of the entire drivetrain, especial
-
ly the engine, and combines the benefits that otherwise distinguish hard and soft
gearbox mounting arrangements.
A hard gearbox mounting delivers optimum
dynamic performance because it offers a
high degree of handling precision. Soft
gearbox mounts, on the other hand, mini
-
mise oscillations and vibrations. While
comfort is improved on uneven road
surfaces, this comes at the expense of

dynamic performance.
Dynamic gearbox mounts adapt their
stif fness and damping characteristics to changes in driving st yle and road surface
conditions. This has been achieved by
use of a fluid with magnetic properties in
interaction with an electrically generated
field. For the driver, the results are tangi
-
ble. Handling is perceptibly more stable
under load change conditions and in fast corners. Whenever a less assertive

driving st yle is adopted, the dynamic
gearbox mounts automatically sof ten

to enhance comfort.
The result is uncompromisingly sporty
performance in corners – as well as a
high degree of comfort.
The SPORT or SPORT PLUS but ton
enables you to switch the dynamic gear -
box mounts from ‘Normal’ to ‘Sport ’ or
‘Performance’ mode. In conjunction with
optional PCM, the TFT screen in the right-
hand circular instrument enables you to
view the lateral and longitudinal forces
as they act on the vehicle.

It ’s always worth exploring your own
direction, even if you never know exactly
where this will lead. For this reason, it
pays to have an ingenious safet y concept
on board that employs components that
are just as performance-oriented as the
drivetrain.
In the case of the new Cayman models,
this concept involves an innovative body -
work construction, the stiffness of which
has been purposefully optimised despite
an achieved weight-saving of up to 30 kg
compared with the previous model – a
combination that delivers increased stabi -
lit y and agilit y. It includes an interior that
provides reliable protection in the event of
an accident. It uses a chassis and brakes
that have been specifically matched to
the power output that the new Cayman
models are able to develop. And it is
enhanced by intelligent control systems,
such as Porsche Stabilit y Management
(PSM), which intervene when you reach

the limits of sport y performance.
Some things are indispensable for a broad
view – including a clever lighting concept
with powerful headlights and, of course,
driver assistance systems designed to
give you the right information at the right
time so that you can devote all your at ten -
tion to the next corner.
engineered body design.
The bodyshell of the new Cayman models
is based on an intelligent light weight
principle involving the composite construc -
tion of aluminium and steel. The use of
dissimilar but precisely combined compo -
nents makes it possible to utilise specific
material properties exactly where they
are needed. Not only does this provide a
high degree of safet y for the driver, it
also offers a considerable weight saving
compared with the bodyshell of the prev -
i
ous model. This is why the doors, luggage
compartment lid and rear hatch are made

entirely of lightweight aluminium. Alumi -
nium accounts for around 44 % of the

entire bodyshell. The crumple zones in the front and rear
aprons feature integral light-alloy bumpers,
while impact absorbers offer additional
safet y. For the protection of occupants,
energy-absorbing padding is used selec
-
tively in important areas within the passen -
ger cell.

a irbags.
To protect the driver and passenger,
the new Cayman models are equipped
as standard with full -size airbags, which
are inflated in t wo stages depending on
the severit y and t ype of accident (e.g. frontal or offset frontal). In less serious
accidents, the airbags are only partially
inflated, thereby minimising discomfort

to the occupants. In addition to the central airbag control
unit on the transmission tunnel, a pair

of impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated far sooner and
with considerably greater accuracy.

A design is either fascinating or functional.
The front and rear lights of the new
Cayman models can be both. Clear glass

equipped as standard with Bi-Xenon
headlights. In classic Cayman fashion,

the circular front light units with LED

are integrated in the air intakes. LEDs
provide powerful illumination, respond
extremely rapidly to driver input and
offer improved energy performance

combined with a longer service life. The

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

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.

Environment
Fuel economy and recycling.
Intelligent lightweight construction is, and
always has been, a fundamental aspect of
the Porsche philosophy – for both techni -
cal and ecological reasons. This combina -
tion forms the basis for achieving low fuel
consumption values in conjunction with
high performance. On the technical side,
various components are made with a high
proportion of alu minium, magnesium, plas -
tics and super- high -strength sheet steel.
The materials used have been selected
for their abilit y to withstand load, yet they
are considerably lighter than conventional
steel. As a result, the bodyshell of the new
Cayman models has a light alloy content
of approximately 44 %.
On the ecological side, all materials used
are meticulously selected. We use only state-of-the-art components, with priority
given to products manufactured in a sus
-
tainable manner where possible. All syn -
thetic components are easily recyclable
and each material is labelled to facilitate
its separation for recycling. The reduction
in the number of plastic variants helps to
ensure more efficient recycling. Recycled
plastics are used where they meet our
exacting technical requirements.
In short, the new Cayman is around 95 %
recoverable.
In addition, Porsche uses a high proportion
of environmentally friendly water-based
paints. For us, environmental protection
does not begin with the vehicle manufac -
turing process. It starts at the planning
and development stage.
Fuel.
The new Cayman models are designed to
operate on fuels with an ethanol content of
up to 10 %. Ethanol has a positive impact
on the CO2 balance since the plants grown
for the production of this biofuel also
absorb CO
2 from the atmosphere. The
release of hydrocarbons from the fuel

system has been minimised thanks to the
active carbon filter and the multilayered
material from which the fuel tank is made.
Servicing.
Long service intervals offer clear advan -
tages. For you, they reduce costs and
save time. For the environment, they assist
in the sparing use of consumables and
replacement parts. For full details of ser -
vice intervals, please refer to the separate
price list.
