series production.

In detail, SMG means that in contrast to a conventional manual transmission, the clutch control and gear change are
automated. An electrohydraulic control system takes over the clutch operation and gearshifts.
The SMG can be driven in manual mode or in automatic mode, as follows:
-
Manual mode: sequential, manual gearshifts
Gears are selected in sequence (sequentially) by briefly pressing "+ or "-". Gears can be skipped by rapidly
pressing the button repeatedly.
Gears are changed by one of the following means:
•
Gear lever in the centre console, or
•
2 gearshift paddles on the steering wheel.
The shift pulse is transmitted electrically to the SMG control unit. With this gearshift method ("shift-by-wire")
there is no mechanical linkage between the gear lever or gearshift paddles and the transmission.
