A high-performance engine needs an adequate
transmission. Which is why the Audi RS 4 Avant
has a dual-clutch transmission that stands out
through fast gear changing and a high degree
of efficiency.
The 7-speed S tronic comprises two multi-plate
clutches and two transmission parts. These are
both permanently active, but only one of them
is actually connected to the engine. For example,
if the vehicle is accelerating in third gear, then
the second part of the transmission is already
engaged in fourth gear. The gear change happens
through the change of clutches – the first clutch
opens whilst the second one closes. The gear
change
only takes a few hundredths of a second
and is completed with virtually no break in
propulsive power. So quickly and smoothly that
it is hardly perceptible. You can choose whether
you want to change gear yourself or leave it up to
the transmission. In manual mode, you influence
the gear change via shift paddles on the steering
wheel or by briefly touching the selector lever.
In automatic mode, you can change the gear
changing characteristics by selecting the programs
D (Drive) and S (Sport) or through Audi drive select.
Even with all of this dynamic technology, the
S tronic still remains very efficient, however. Its
high level of efficiency contributes to reducing
both fuel consumption and emissions. In addition,
the seventh gear with long transmission ratio
has been designed as overdrive.
What is the benefit of two clutches?
A double saving: time and energy.
The fuel consumption and CO₂ emission figures can be found on page 60.
