The 911 | Transmission
911 Carrera S Cabriolet
Inner strength alone is not enough.
It somehow needs to be put to use.
Six-speed manual gearbox.
Accurate and involving: the
six-speed manual gearbox is the
link to each and every gear. The
cable-operated gearshift unit is
designed for optimum progression
through the gears and the gear
lever is insulated from the engine
and gearbox.
The gear lever throw is short and
precise, enabling a rapid gearshift
action and positive response. An
optional short shifter is available
from Porsche Exclusive.
In addition, all 911 models have
a self-adjusting clutch. In compa-
rison with conventional clutches,
this reduces by up to 50 % the
added release loads that normally
occur as the clutch begins to
wear.
Hill-start assist.
Hill-start assist comes as
standard for manual and Porsche
Doppelkupplung (PDK) transmis-
sions. It assists the driver in
making a comfortable, smooth
and roll-free start on an incline.
The system automatically detects
that the vehicle has been braked
to a halt on an incline. Provided
a gear is engaged, the brake
pressure is maintained at all
four wheels for approximately
2 seconds once the footbrake is
released. The vehicle is therefore
temporarily prevented from rolling
backwards. This brake pressure
is reduced once sufficient revs
have been generated by the
driver depressing the accelerator
pedal (or, in the case of manual
transmission, the accelerator
pedal is depressed and the clutch
is released).
