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 gearchanging 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,
when the driver accelerates in third gear, the
second part of the transmission is already set 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 lasts
a few hundredths of a second and is completed
with almost no interruption in the power flow. 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 gearshift 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.
