gearbox PORSCHE CAYMAN 2006 1.G Information Manual

· 25 ·
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.
These are augmented by highlights

and gear console surround.
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.

in every detail.

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
steering wheel, gear lever,

handbrake lever, door
handle facings and storage
compartment lids on the
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.

Tiptronic S.
Both Cayman models are available
with five-speed Tiptronic S as
optional equipment. This versatile
system combines an automatic
transmission with the option of
manual gearshifts.
For manual control, simply slot
the gear selector into the manual
gate and use the gearshift controls
on the steering wheel. Press up
to change up, and down to change
down. Gearshifts are performed
in around 0.2 seconds with
virtually no interruption in drive.
The action is comparable with
that of a manual gearbox.
Switch to automatic, and you can
still change gear by hand using
the rocker controls on the steering
wheel. This race-derived function
is particularly useful during
overtaking manoeuvres. If there
is no manual input for a period
of eight seconds, the system will
revert to automatic mode. The
drive position and gear selection
are displayed at all times on a
dedicated cockpit display.
In automatic mode, Tiptronic S
can choose from a range of
gearshift points for each individual
gear. The standard gearshift
pattern, designed for maximum
fuel economy, can be steplessly
varied up to a dedicated ‘Sport’
configuration for optimum high-
performance driving. Each
gearshift point is automatically
selected based on current road
conditions and driving style. Within
a short space of time, you’ll
develop a feel for the system and
begin to influence gearshifts using
the throttle alone. The benefits
of Tiptronic S are particularly
apparent when exploring the car’s
performance. Even in automatic,
the rapid gearshift action
enhances the agility of the car.

Both the Cayman and Cayman S

immediate driving experience. A
crucial element within that concept
is the standard manual gearbox.

mechanical noise and thus greater
focus on the natural sound of the
engine. The flywheel is mated to
a hydraulically operated clutch,
while the final drive ratio has been
carefully selected for optimum
sports performance. The gearshift
mechanism is cable operated
so as to insulate the lever against
vibration from the engine and
gearbox.
Other useful functions include a
warm-up programme, automatic
selection of the ‘Sport’ gearshift
pattern by means of rapid throttle
inputs, gearshift suppression
during cornering manoeuvres,
automatic downshifts under heavy
braking, an incline sensor
