Two different characters. One
personality. 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 gravity gave it
tremendous agility 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 two engine
developments, which stand
out above all for their lightweight
construction, power output
and efficiency. 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
after 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 mighty
235 kW (320 hp). Depending on
the model, it has been possible
to reduce fuel consumption by
up to 15 % and CO emissions by
2
up to 16 %.
In either model, this tremendous
power is delivered to the road
by a precision six-speed manual
gearbox.
Cayman
Porsche Doppelkupplung (PDK,
p. 48) is available as an option.
The key elements of PDK are its
seven gears, two half gearboxes
and two 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
gearshift paddles with race track
control logic. The gear change
takes place in a matter 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.
