Two examples of the uncompromising efforts of our engineers.
Going forward.
The engines of the Cayman models.

Cayman S features direct fuel
injection (DFI, p. 34) and has a a host of other engineering
advancements, e.g. VarioCam Plus

torque in the lower engine speed
range and power output in the
upper engine speed range. Injec

VarioCam Plus
To improve throt tle response
during the warm -up phase,
VarioCam Plus selects high valve
lif ts with retarded valve timing.
In the middle and low load ranges,
low valve lif ts with advanced
timing reduce fuel consumption
and exhaust emissions. High valve
lif ts generate high torque and
maximum output.Two-stage resonance
intake manifold.
The intake manifold with
double-flow distributor pipe has
an adjustable flap that closes and
opens at defined engine speeds.
As a result of a t wo -stage
resonance ef fect, the air mass in
the intake manifold begins to
oscillate, which in turn generates
a turbocharging ef fect and
optimises induction. These t wo
ef fects combine to produce
higher torque at low engine
speeds, a flat ter torque curve and
increased power output at high
engine speeds, while the acoustic
properties of the system are
second to none. A sound that is
typically Porsche.
VarioCam Plus.
VarioCam Plus combines variable
valve timing with t wo -stage lift
on the inlet side. This results in
smoother running, bet ter fuel
economy and lower exhaust
emissions. As well as greater top-
end power and low- end torque. This two-in-one engine concept
seamlessly adapts in response
to driver input. The result: instant
acceleration and extremely
smooth running.
The variation in intake timing
is steplessly controlled by means
of an electrohydraulic rotary
vane adjuster at the head of the
corresponding camshaf t.
