2012 PORSCHE CAYMAN S wheel torque

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.

Cayman S
Those who give their all,
should be given it all back.

The new Cayman S.Having an idea is one thing, thinking it
through to the end is another. Some-
times you have to give your all, and with
the new Cayman S this is exactly what
we did – in every respect and with suc -
cess. Its 3.4-litre flat-six engine with DFI
and VarioCam Plus generates 239 kW
(325 hp). It accelerates from 0 to 100 km/ h
(0–62 mph)
in 5.0 seconds and achieves

a top speed
of 283 km/ h (175 mph).
With PDK and the Sport Chrono
Package, both of which are optional, it
reaches 100 km/ h in just
4.7 s e c o n d s. Improved performance demands capable
components. The chassis of the new

Cayman S is matched specifically to the
high power output of the engine. Even
greater levels of agilit y, traction and con -
trol in corners can be achieved with
Porsche Active Suspension Management
(PASM), Porsche Torque Vectoring (PTV)
with rear differential lock and the dynamic
gearbox mounts of the Sport Chrono
Package – all of which are available from
our list of options. For added safet y, the
front axle is equipped with larger brake
discs to cope with the increased engine
power. The brake calipers are finished
in red. Imposing 19-inch Cayman S light-
alloy wheels with a classic five-spoke
design are fit ted as standard.
On the new Cayman S, Bi-Xenon headlights
are fit ted as standard. The precisely st yled
LED front light units accentuate the front
air intakes finished in black. At the rear,
the twin tailpipe in brushed stainless steel is located in the centre and produces the
typically resonant
Porsche sound.
For the new Cayman S, we gave our all.
As a mat ter of principle, out of passion
and in anticipation of the corner ahead.

2 emissions and efficiency class, please refer to page 131.

Another key advantage of PCCB is the
extremely low weight of the ceramic brake
discs, which are approximately 50 % light-
er than standard discs of a similar design
and size. As well as enhancing perfor -
mance and fuel economy, this represents a major reduction in unsprung and rotat
-
ing masses. The consequence of this is
bet ter road holding and increased com -
fort, particularly on uneven roads, as well
as greater agility and improved handling. Please note that circuit racing, track day
use and other forms of performance driv
-
ing can significantly reduce the service
life of even the most durable pads and
discs. As with conventional high-perfor -
mance braking systems, we recommend that all brake components be profession
-
ally inspected and replaced where neces -
sary after each track event.
e lectric parking brake.
The electric parking brake, which can be
activated and deactivated manually, is
released automatically as you pull away
with your seat belt fastened. A hill hold
function is integrated as standard for the
manual gearbox and for PDK. It assists
you in making a comfortable, smooth
and roll-free start on an incline. Whenever
you come to halt on an incline, this is
detected automatically and the braking
effect of the electric parking brake is

supplemented by application of the wheel
brakes. As long as a gear remains en -
gaged, the brake pressure is maintained
at all four wheels. To pull away, simply
apply throt tle. As soon as sufficient
starting torque is available, the brake
is
released and the vehicle moves off.

Porsche Stability management (PSm).
Enhanced Porsche Stability Management
(PSM) is fit ted as standard. This system
automatically maintains stability and trac -
tion even at the limits of dynamic driving
performance. Sensors continuously moni -
tor the direction, speed, yaw velocit y and
lateral acceleration of the car. Using this
information, PSM is able to calculate the
actual direction of travel at any given
moment. If the car begins to oversteer or
understeer, PSM applies selective braking
on individual wheels in order to restore
stability.
Under acceleration on wet or low-grip road
surfaces, PSM improves traction – as well
as agilit y, control and safet y – using the
automatic brake differential (ABD) and
antislip regulation (ASR). Integrated ABS

is designed to minimise braking distances.
If you prefer an ever sportier drive, PSM
can be switched off. For your safet y,
however, PSM remains set to intervene if
the vehicle is braked and ABS assistance
is required.
Also included with PSM are engine drag
torque control (EDC), precharging of the
brake system and brake assist. If you
suddenly release the accelerator pedal
,
PSM automatically prepares for your next
action: the braking system is precharged
so that the brake pads are already in light

contact with the brake discs. Maximum
braking power is therefore achieved
much sooner. Brake assist detects a
panic braking situation and generates

the brake pressure required for maximum
deceleration.
PSM increases driving stabilit y and safet y
as well as the agilit y you have come to
expect from a Porsche.

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.
