The duration of downshifts for
the DSG is comparable to other
transmissions.
Downshifts take place with
multiple declutching.
The reason for multiple
declutching is to reach the
synchronization speed of the
engine for the selected gear as
quickly as possible. To achieve
this, multiple declutching is
activated until the
synchronization speed is
reached.
During this process, the vehicle
does not accelerate.
Depending on the driving
situation, this process lasts
for less than 1 second.
No action
