Porsche Doppelkupplung (PDK).
The 7-speed PDK – fitted as
standard in the Panamera 4,
Panamera 4S and Panamera Turbo
and available as an option in the
Panamera and Panamera S –
has both a manual gearshift and
an automatic mode and enables
smooth gear changes with no
interruption in the flow of power.

Gear lever
Six-speed manual gearbox.
For precision handling: the 6-speed
manual gearbox fitted as standard
in the Panamera and Panamera S
is tuned for sporty performance
with optimum connection to
the individual gears and extremely
precise shift throws. Thanks to the elevated centre
console, the gear lever is within
easy reach – ideal for sporty
shifting. The cable-operated gear-
shift unit has a precise feel and
the gear lever is insulated against
vibration. Together with the dual-
mass flywheel, this minimises
noise and is key to providing a
high level of comfort.
An upshift indicator in the instru-
ment cluster helps to further
improve fuel economy. Porsche
Doppelkupplung (PDK) is available
as an option for both of these
models.
Gears 1 to 6 have a sports ratio
and top speed is reached in 6th
gear. The 7th gear has a long
ratio, which reduces fuel consump-
tion even further and keeps engine
revs comfortably low even at
high road speeds. PDK is essentially two gearboxes
in one and thus requires two
clutches. This double clutch pro-
vides an alternating, non-positive
connection between the two
half gearboxes and the engine by
means of two separate input shafts
(input shaft 1 is nested inside
the hollowed-out input shaft 2).
