At Porsche, we have always
followed our instincts. To
make cars which follow yours.
Responding directly with
precision and immediacy to
every input you make.
Instinct is all about being in the moment.
For us, that’s something of a tradition.
The new Cayman and the Cayman S.
Achieving that level of vehicle
response requires careful
consideration. It takes many
years of continuous evolution to
arrive at each new revolutionary
development.The new Cayman and the Cayman S
are pure, direct and involving. They
also exude a familiar Porsche
character more than five decades
in the making.
The new Cayman and the Cayman S |The Cayman
The key to that character, as on
every Porsche, is the underlying
vehicle concept. This unique
combination of mid-mounted engine
and hard-roof body was originally
prototyped in 1953 on the
Porsche
550 coupé. A closed-top
version of the legendary 550
Spyder, it was specially developed
for the 24 Hours of Le Mans.
Now we’ve combined this race-
winning concept with more than
five decades of road and race
experience. The result: the new
Cayman and the Cayman S.
Each is powered by a free-revving,
high-torque, mid-mounted engine
with a low-lying centre of gravity.
The new Cayman has a 2.7-litre
flat-six unit developing 180 kW
(245 bhp) and 273 Nm of torque.
The Cayman S produces 217 kW
(295 bhp) and 340 Nm from a
displacement of 3.4 litres. Both
cars deliver maximum torque from
surprisingly low engine speeds.Powerful acceleration is instantly
available, in every situation.
The respective top speeds are
258 km / h (160 mph) on the
new Cayman and 275 km / h
(171 mph) on the Cayman S.
Each car has an elegant and
purposeful exterior design,
offering more than just visual
appeal. The coupé body is
aerodynamically refined, producing
a drag coefficient of just 0.29
(Cayman S with Tiptronic S: 0.30).
The monocoque shell has
additional benefits in terms of
torsional and flexural strength.
This in turn promotes greater
agility and positive driving
dynamics.
The precision handling is a
direct result of uncompromising
chassis engineering. The
standard suspension offers agile
performance as well as excellent
long-distance comfort. The front
and rear axles feature McPherson-
strut suspension, a wide track
and generous wheel dimensions.
Combining it all is the most
important factor: the overall
suspension setup. Stable and
responsive, it is, of course,
balanced with appropriate levels
of comfort.
Matching the suspension in
terms of agility and safety are
the standard Porsche Stability
Management (PSM – see page
64) and the variable-ratio steering
system. Together, they enhance
your involvement with the car,
offering almost surgical precision
on turn-in to a corner and
increased safety in critical
scenarios.
For even greater performance
and occupant comfort, there’s
the optional Porsche Active
Suspension Management (PASM –
see page 52). This 10-mm
lowered variable suspension
system provides active control
of the damping force on each
wheel based on changing road
conditions, individual driving style
and the selected setup mode
(‘Normal’ or ‘Sport’).

Designed entirely around the
driver, the new Cayman is a
contemporary interpretation of
a classic Porsche concept. The
six-cylinder boxer engine has a
2.7-litre displacement generating
180 kW (245 bhp) at 6,500 rpm.
Thanks to VarioCam Plus (see
page 39), the maximum torque
output of 273 Nm is available
between 4,600 and 6,000 rpm.
The mid-engined layout is a crucial
factor in the near perfect front/
rear weight distribution. It also
enhances the car’s rear-end
traction, enabling 0 to 100 km / h
(62 mph) in as little as 6.1 seconds.
Maximum speed in appropriate
track conditions is 258 km / h
(160 mph).
The second key factor when it
comes to performance is, of
course, aerodynamics. Honed in
the wind tunnel, the new Cayman
has a drag coefficient of just 0.29.
Power is transmitted with precision
to the road through a five-speed
manual gearbox. An optional Sport
package is also available,

combining a six-speed manual
gearbox with Porsche Active
Suspension Management
(PASM – see page 52). Five-speed
Tiptronic S, offering both manual
and automatic gearshifts, is
also available as an option.
The standard wheels have a 17-inch
diameter and attractive dual-spoke
design. Clearly visible behind
them are the four-piston fixed brake
calipers in monobloc aluminium
with black anodised finish. All four
discs are vented and cross-drilled,
enabling better performance in wet weather conditions and lower
unsprung weight.
Other distinctive features on the
new Cayman include black lip
spoilers at the front of the car and
a centrally mounted, single-tube
tailpipe. Accompanying it all is the
familiar sound of the Porsche flat-
six engine.
The interior of the car is an
elegant arrangement of smooth
and clearly defined surfaces.

Genuine leather trim can be found
on the steering wheel, gear lever,
handbrake lever and door handle
facings. On entering the car, the
first thing to catch your eye is the
Cayman logo on the outer door-sill
guard. The second is the stylish
instrument cluster with classic
black instrument dials. The
instrument shroud unites all three
instruments into a single visual
unit.

A fundamental principle of Porsche
engineering is the search for
efficient performance. In the
Cayman S, the six-cylinder boxer
engine develops 217 kW (295 bhp)
from a 3.4-litre displacement.
Maximum torque of 340 Nm is
available between 4,400 and
6,000 rpm. VarioCam Plus
(see page 39) helps to increase
torque at lower engine speeds
and optimise top-end power. Theresults? An immediate response
to throttle inputs, 0 to 100 km / h
(62 mph) in as little as 5.4 seconds,
and a top speed of 275 km / h
(171 mph).
Working with the engine to achieve
that performance is a highly refined
aerodynamic package. Indeed, the
Cayman S has a drag coefficient
of just 0.29 (with manual gearbox;
Tiptronic S: 0.30).
Power and torque are applied
with precision through a short-
throw six-speed manual gearbox.
Tiptronic S is available as an
option, offering fully automatic or
manual gearshifts via rocker-type
controls on the steering wheel.
Externally, the Cayman S differs
from the Cayman in its colour-
coded lip spoilers at the front of
the car and dual-tube tailpipe
The new Cayman and the Cayman S |Model range
design. In keeping with its
higher performance capability, the
Cayman S comes with 18-inch
wheels as standard. The generous
internal diameter accommodates
a standard braking system with
internally vented and cross-drilled
discs which are larger than those
on the Cayman.
The discs are combined with four-
piston monobloc aluminium fixed
calipers featuring a red paint
finish unique to the Cayman S.
As an optional alternative to the
standard braking system, there’s
the ultra-high performance
Porsche Ceramic Composite
Brake (PCCB – see page 62).
As you would expect, the interior
of the car is exclusively designed
around the driver. Every material
exudes elegance and sporting
style. The instrument dials have an
aluminium-coloured background
which is tastefully matched to the
Aluminium Look trim on the gear
console surround and dashboard.
The standard interior includes
a genuine leather finish on the

handbrake lever, door
handle facings and storage

doors and centre console.
As a finishing touch, there’s a
Cayman S logo on each of the
outer door-sill guards.
Equally attractive are the car’s
lengthy service intervals. Not
only do they minimise the cost
of ownership, they also keep
your car longer on the road.

Porsche Active Suspension
Management (PASM).
PASM is an electronic damping
control system. Available on
both Cayman models, it offers
continuous adjustment of
individual damping forces based
on current road conditions and
driving style. Agility and driving
pleasure are significantly
enhanced while retaining the
car’s natural ride quality. Equipped
with PASM, the car rides 10 mm
lower than with the standard
steel-sprung suspension.
The driver can choose one of
two setup modes, ‘Normal’ or
‘Sport’. While the first is a blend
of performance and comfort, the
‘Sport’ setup ratings are generally
much firmer, enabling greater
agility on the racetrack. In either
mode, the system responds to
changing loads by automatically
applying the optimum damping
rate on each individual wheel.
The rates are selected from a
range of map options which are
specially adapted to the unique
dynamics of the Cayman and
Cayman S.
The movement of the body is
continuously monitored under
acceleration, braking and cornering
manoeuvres, as well as on poor
road surfaces. Other sensors
provide additional information on
lateral acceleration, steering
angle, brake pressure and engine
torque. A dedicated control unitprovides real-time analysis and
damper adjustment as defined
for the respective setup mode
(‘Normal’ or ‘Sport’). The result:
greater stability and more
consistent occupant comfort.
If, when ‘Sport’ mode is selected,
the quality of road surface drops
below a certain threshold, the
system immediately switches
to
a softer rating and restores
the car’s traction and grip.
When the road surface improves,
PASM returns to the original,
harder ratings. The system
remains active in ‘Normal’ mode,
too, automatically switching to a
harder setup if the car is driven
more assertively. As the dampers
become stiffer, the car becomes
more stable and driver control is
improved.
