Six-speed manual gearbox.
The new Cayman models are equipped
as standard with the six-speed manual

gearbox. Gearshifts are smooth, precise
and optimally adapted to the respective
engine map. Shift throws are short and
the gear lever is easy to operate, provid -
ing a truly engaging driving experience.
The upshift indicator located in the central
circular instrument helps you to maximise
fuel efficiency.
The ascending centre console reinforces
the authentic sports car feel. It positions
the gear lever close to the steering wheel,
enabling you to change gear as fast and
as ergonomically as possible.
Porsche Doppelkupplung (PDK).
Of course, you could let us take care of
the gearshift strategy so that you can
devote all your at tention to your cornering
strategy.
Available as an option is the completely
retuned 7-speed Porsche Doppelkupplung
(PDK), featuring both manual and auto -
matic modes. The advantages are percep -
tible. Gear changes take place with no
interruption in the flow of power. Sharper
gearshift programs and significantly short -
er shift times produce faster acceleration
than with the manual gearbox. Fuel econ-
omy and comfort characteristics have also
been optimised. In response to a less
assertive driving st yle, shif t points are

recalculated to make use of the more
comfortable and more economical engine
speed ranges, and coasting mode is acti -
vated where possible (p. 44).
This is how PDK works: PDK is essentially
t wo gearboxes in one, thus requiring t wo
clutches. This double clutch arrangement
provides an alternating, non-positive con -
nection between the two half gearboxes
and the engine by means of t wo separate
input shafts. The flow of power from the
engine is transmit ted through one half
gearbox and one clutch at a time, while

the next gear is preselected in the second
half gearbox. During a gear change, there -
fore, one clutch simply opens and the
other closes at the same time, enabling
gear changes to take place within milli
-
seconds.
PDK has seven forward gears at its
disposal. Gears 1 to 6 have a sports
ratio and top speed is reached in sixth

gear. Seventh gear has a long ratio and
keeps
engine speed low to reduce fuel
con
sumption and improve comfort.

With the SPORT but ton selected, the full
advantages of the new version of PDK
are brought into play: a more immediate
response to throt tle inputs, relatively
short shift times and swift throt tle-blip
downshifts on overrun, such as during
braking into a corner, and always accom -
panied by an emotive engine sound.
With the optional Sport Chrono Package,
PDK is enhanced by ‘Launch Control’
and the ‘motorsport-derived gearshift
strategy’ for even faster and firmer gear
changes and best possible per formance,
thanks to a boost in torque during up -
shift phases. Overrun downshifts provide
extremely sport y braking and accelera -
tion for added excitement.
Coasting.
Efficiency is another area in which the
performance of the new Cayman models
has been further improved. The coasting
function available with Porsche Doppel-
kupplung (PDK) enables you to save even
more fuel where the situation allows.
The engine is decoupled from the trans -
mission to prevent deceleration caused
by engine braking. In this way, optimum
use is made of the vehicle’s momentum,
allowing it to coast for longer distances.
For example, you may want to slow down
from 100 to 80 km/ h (70 to 50 mph) in
anticipation
of the change of speed limit
ahead. As you ease off the accelerator
pedal, PDK deselects the current gear
automatically and you begin to coast in
neutral with minimal input required on
your part until
you have reached your desired speed.
As soon as you operate
the accelerator
or brake pedal, PDK
re-engages the appropriate gear within
fractions of a second. The process
is smooth and seamless, thanks to the
extremely fast
clutch.
Another way to reduce fuel consumption
is to utilise the coasting function on down -
hill gradients that are gentle enough for
you to maintain a constant speed. Efficient
on long journeys, such as on the motor -
way, PDK remains ready to respond as

swiftly and precisely as you would expect.
In short, driving in coasting mode makes
a real impact on fuel consumption without
the need to compromise on comfort or
sporty performance.

Performance needs sustained stability.
Fit ted as standard on the new Cayman,
18-inch alloy wheels are responsible for
maintaining the strong connection be -
t ween the vehicle and the road. A mini -
malist dual -arm spoke design accentuates
their sport y character – and yours. Tyre
sizes are 235/45 ZR 18 at the front and
265/45 ZR 18 at the rear.
The Cayman S is equipped as standard
with 19-inch wheels with a classic five-
spoke design. The t yre size at the front is 235/40 ZR 19 and 265/40 ZR 19 at
the rear.
Wheels up to 20 inches are available
from our list of options. The large rolling circumference helps to
improve comfort. At the same time, the
rolling resistance of the new generation

of t yres has been reduced, which, in turn,
helps to reduce fuel consumption.

Optional Tyre Pressure Monitoring (TPM)
sends warnings to the on-board comput -
er’s display screen in the event of low
t yre pressure. The TFT screen in the

instrument cluster enables the driver to
check the pressure in all four t yres. The system updates quickly and

accurately af ter an engine start, t yre

for increased comfort and your safet y.

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.
