On vehicles with automatic transmis-
sion, the ATC (Adaptive Transmission
Control) uses a number of factors to
calculate the maximally efficient gear. In
this process, it considers your individ-
ual driving style as well as current driv-
ing conditions.
ATC recognizes your personal driving
style from the positions and movements
of the accelerator pedal, deceleration
when braking and lateral acceleration
through curves. Based on different shift
characteristics – from comfort-oriented
to performance-oriented – ATC will se-
lect the appropriate gear.

In order to include driving conditions in
its calculations, ATC registers curves
and both uphill and downhill gradients.
For example, if you maintain speed
through a curve, it does not upshift. On
uphill gradients, it shifts up only when
the engine speed increases in order to
make more efficient use of power re-
serves. On downhill gradients, ATC
shifts down when the speed of the vehi-
cle increases and the driver must apply
the brakes.
