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 three-spoke sports steering
wheel or the new optional three-
spoke sports steering wheel with
gearshif t paddles with race track
control logic. The gear change
takes place in a mat ter of millisec -
onds 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 Cayman models follow a
clear line. Their own. Even when it
comes to the chassis. The driver’s
connection to the road is an
essential priorit y at all times, fast lane changes and through
tight corners, this chassis is in its
element. Thanks to the mid- engine
layout and the construction of
the bodyshell, roll and pitch are
practically eliminated. The chassis
responds with absolute precision
along with the delivery of the
engine’s power.
For this reason, the Cayman
models are equipped with
a light weight suspension with
transverse links and spring to acceleration and braking. The
light weight construction keeps
the vehicle gross weight and the
weight of the unsprung masses
low. Virtually all moving axle parts
are made of aluminium.
An expression of agility on the road
