Sequential M gearbox with Drivelogic*
The concept
The sequential M gearbox with
Drivelogic is an automated manual
gearbox with which clutching and shift-
ing is assumed by an electro-hydraulic
system.
Drivelogic is an automated manual
gearbox with which clutching and shift-
ing is assumed by an electro-hydraulic
system.
The SMG Drivelogic is operated via two
shift paddles on the steering wheel and
the selector lever in the center console.
shift paddles on the steering wheel and
the selector lever in the center console.
It offers the following functions:
> Sequential and automated shifting
> Sequential and automated shifting
mode
> Ability to choose between different
driving programs – Drivelogic
> Upshift display and shift lights, refer
> RPM matching on downshifts
> Driving dependent functions:
The respective driving situation, e.g.
cornering, mountain driving or brak-
ing, is detected by sensors and taken
into account for shifting, e.g. to
achieve optimum gear selection dur-
ing deceleration and subsequent
acceleration

> Slip recognition at the rear axle for
increasing driving stability, e.g. dur-
ing downshifting on slippery road
surfaces
ing downshifting on slippery road

> Operating safety through protection
against misshifting.
Under normal operating conditions, fuel
consumption is lowest when driving in
the first driving program of the auto-
mated shifting mode.

For your safety, it is only possible to
engage a driving position with the vehi-
cle stopped approx. two seconds after
engaging position 0 with the footbrake
depressed – shift-lock function.
