Automatic
Transmission
multitronic, S tronic,
tiptronic
Introduction
App lies to vehicles: with multit ronic/S tronic/t ipt ronic
The automat ic transm iss ion is controlled elec-
tronically . The transmiss ion ups hifts or down-
shifts automatically depend ing o n which drive
prog ram is se lect ed.
When a
moderate driving style is used, the
tra nsmission selects the most econom ical
driving mode .
It will t hen change up early and
de lay the downshifts to g ive bette r fuel econ-
omy.
The transmission switches to a sporty mode
after a kick-down or when the drive r uses a
sporty driving style characte rized by quick ac-
celerator peda l movements, heavy accelera-
tion, frequent changes in speed and t raveling
at the maximum spee d.
If desired, t he drive r can also se lect the gears
manually (tiptronic mode) ¢ page 111.
Various automat ic transm issions may be in-
stalled, depend ing on the mode l:
multitronic transmi ssion
The mult itron ic transm ission is a continuously
variable transmission. Power is transferred us-
ing a mu ltidisk clutch . In contrast to conven-
tional automat ic transm iss ions using shift ing
ope rations, the transmiss ion ratio in the con-
tinuously variab le transm iss ion is changed
con t inuously. This opti mizes t he com fort level
and conserves fuel.
S tronic transmission
The S tronic is a dual -clutch transmission .
Powe r is transfe rred using two clutches that
wo rk ind ependen tly from one another. They
re place the t orqu e conve rt er used in conven-
tional a utoma ti c t ransm iss ions an d allow t he
ve hicle to accelerate without a not iceable in-
ter ruption in traction.

In t he t ipt ronic t ransm issio n, power is t rans -
ferred by a t orque converter .
