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
comparison with conventional
clutches, this reduces by up
to 50% the added release
loads that normally occur as
the clutch begins to wear.
Inner strength alone is not enough.
It somehow needs to be put to use.

Hill-start assist.
Hill-start assist comes as
standard for manual and
Porsche Doppelkupplung (PDK)
transmissions. 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).
