Introduction
Appl
ies
to
vehicles: with
mult itronic/5
tronic/t iptronic
The automatic
transmission
is controlled elec-
tronically.
The
transmission upshifts or
down-
shifts automatically
depending
on which
drive
program is selected.
When a
moderate driving
style
is
used, the
transmission selects the most economica
l
driving
mode. It will then change up early and delay the
downshifts to give better fuel economy
.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a
sporty
driv-
ing
style
characterized by quick accelerator pedal
movements,
heavy
acceleration, frequent
changes in speed and traveling at the maximum
speed
.
If desired, the driver can also select the gears
manually
(tiptronic
mode)

Various automatic
transmissions
may be instal
-
led,
depending
on
the model:
multitronic transmission
The
multitronic transmission
is a continuously
variable
transmission. Power
is
transferred using
a
mu
lt
idisk
clutch.
In
contrast
to
conventional
automatic transmissions
using
shifting opera-
tions, the transmission ratio in the continuously
variable transmission is changed continuous ly.
This optimi zes the comfort
level
and conserves
fuel.
S tronic transmission
The 5 tronic is a
dual-clutch
transmission.
Power
is transferred
using
two clutches that work inde-
pendently from one another. They replace the
torque converter
used in
conventional automatic
transmissions and allow the vehicle to accelerate
without a
noticeable
interruption in traction
.
tiptronic
transmission
In the tiptronic transmission,
power
is transfer-
red by a torque converter.
