2011 PORSCHE CAYMAN S wheel torque

Porsche Doppelkupplung (PDK,
p. 48) is available as an option.
The key elements of PDK are its
seven gears, t wo half gearboxes
and t wo clutches. It features both
manual and automatic modes.
Gears are changed using the gear
selector for PDK, the switches
on the sports steering wheel or
the new optional SportDesign
steering wheel with gearshift
paddles with race track control
logic. The gear change takes
place in a mat ter of milliseconds
without any interruption in the
flow of power. The advantage

over a fully manual transmission
is the considerably faster rate of
acceleration for the same rate of
fuel consumption. The advantage
over a fully automatic transmission
is the perceptible increase in
driving dynamics – with a similar
level of comfort, and a distinct
reduction in fuel consumption.
Two dif ferent characters. One
personalit y. Their drive for power
is impressive, their spirited nature
fascinating. Two sports coupés
that go beyond all conventions.
Two cars that draw their drivers
under their spell, forever.
The concept behind the Cayman
models is the ‘Le Mans Coupé’,

a sports coupé designed in 1953
specifically for this legendary
race and based on the 550
Spyder. Its mid- engine layout is
what made this car special. The
car’s low centre of gravit y gave it
tremendous agilit y and cornering
dynamics. From this one basic
idea came great success, and
with this success our experience
grew. The result? Two sophisticated
sportscars. The Cayman and the
Cayman S.
Their uncompromising perform -
ance is generated by t wo engine
developments, which stand out
above all for their light weight
construction, power output
and ef ficiency. The Cayman has
a 2.9 -litre flat-six engine with a
power output of 195 kW (265 hp).
Even more impressive are the per -
formance values of the Cayman S
with direct fuel injection (DFI, p. 34).
The fuel/air mixture is prepared

entirely in the combustion chamber
af ter having been metered and
injected directly, with millisecond
precision. This means even more
power and torque. To express
this in figures, its 3.4-litre flat-
six engine unleashes a might y
235 kW (320 hp). Depending on
the model, it has been possible
to reduce fuel consumption by
up to 15 % and CO
2 emissions by
up to 16 %.
In either model, this tremendous
power is delivered to the road
by a precision six-speed manual
gearbox.
The primary target group:
your central nervous system.
The Cayman models.

6,000 rpm. From a standing start,
the Cayman accelerates to 62 mph
(100 km/ h) in 5.8 seconds. With the
optional Porsche Doppel
kupplung
(PDK), this sprint takes just
5.7 seconds. Top speed is 165 mph
(265 km/ h) in conjunction with the
manual gearbox. Equally impressive,
however, is the 10 % reduction in with 5-inch display. An integrated
six- disc CD autochanger is
available as an option.
The Cayman has found its way.
Its own? Without doubt.
The Cayman is the driving force
behind precisely one at titude:
the absolute conviction to remain
true to oneself. No middle roads.
No compromises. No nonsense.
One of the features that exempli
-
fies this at titude is the mid- engine
layout, which ensures a low centre fuel consumption and the 12
%
reduction in CO2 em issio ns,
depending on the t ype of gearbox.
The power of the engine is deliv -
ered to the road by a precision
six-speed manual gearbox. Fit ted
as standard are 17-inch wheels
with a star-shaped design, which
allows an eye-catching view of
of gravit y and thus a high degree
of agilit y and an extremely sport y
drive. The six-cylinder horizontally
opposed power unit has a capacit y
of 2.9 litres. The engine delivers a
power output of 195 kW
(265 hp)
at an engine speed of 7,200 rpm.
A maximum torque of 300 Nm
is achieved bet ween 4,400 and the powerful brake system. And
the interior? The overall impression
is simply one of high qualit y. For
instance, the rims of all available
steering wheels are covered in
smooth -finish leather. The centre
console, finished in traditional
black, is equipped as standard
with the CDR-30 audio system
You should never doubt your own principles.
The Cayman.

achieved at 4,750 rpm.
This means, it has been possible
to reduce fuel consumption by
up to 15 % and CO

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
is
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.
The Cayman S.

precise, the outer disc carrier.
Under oil pressure, clutch 1 closes
and forms a frictional connection rapid gearshif ts with no

For maximum dexterit y, PSM
can be set to standby while the
car is still in ‘Sport ’ mode (p. 72).
For safet y, it is set to intervene
automatically only when ABS
assistance is required on both
front wheels.
A key component of the Sport
Chrono Package is the swivel-
mounted stopwatch in the centre
of the dashboard with analogue
and digital display.
In combination with Porsche
Doppelkupplung (PDK), the Sport
Chrono Package offers t wo addi -
tional functions that are activated
by the SPORT PLUS but ton.
First, ‘Launch Control’, which
ensures you achieve the fastest
possible rate of acceleration from
a standing start – on the racetrack,
for example. ‘Launch Control’ is

operated via the SPORT PLUS
but ton with the ‘D’ or ‘M’ drive
position selected. Whilst the driver
depresses the brake pedal
with the lef t foot, the right foot
depresses the accelerator pedal
to the floor. With the accelerator
in the kickdown position, the

The shif t times are shorter, the
gear changes sportier. At low
rates of deceleration, the system
initiates a swif ter, brake-induced
downshift. In manual mode,

gear changes are faster and more
dynamic. In ‘Sport ’ mode, the
PSM system (p. 72) intervenes
later for increased longitudinal and
lateral dynamics. PSM now af fords
greater manoeuvrabilit y under
braking and exit acceleration,
especially at low speeds.
Sport Chrono Package.
Do you think driving a Porsche
should be an even more involving
experience than it is already? Your
wish is our command. On request,
we can equip your vehicle with the
Sport Chrono Package, which is
available for both of the Cayman
models. Its functions enable even
sportier tuning of the engine and
chassis and guarantee even more
driving pleasure.
Selecting the SPORT but ton
on the centre console activates ‘Sport ’ mode, which makes
throt tle response significantly
more immediate, adjusts the
rev-limiter to a harder set ting,

and tunes the engine dynamics
for performance driving.
The optional Porsche Active
Suspension Management (PASM)
also switches to ‘Sport ’ mode,
which of fers harder damping
and more direct steering and,
therefore, bet ter road holding.

request for Launch mode and revs
the engine to an optimum speed
of approximately 6,500 rpm.
Engine torque increases and the
clutch closes slightly. The message
‘Launch Control’ appears on
the display on the steering wheel
for PDK. The driver now quickly
releases the brake – and prepares
for maximum acceleration.
Second, the ‘motorsport- derived
gearshif t strategy’. Using this, PDK
is geared up for maximum shif t
speed, the shortest possible shif t
times and optimum shif t points
for maximum acceleration – for
uncompromising performance.
Sport Chrono Package Plus.
On request, the optional Porsche
Communication Management
(PCM, p. 92) can be combined
with the Sport Chrono Package
