Active
roll stabilization, meanwhile, works by twisting the anti-
roll bars on the front and rear axles, which is itself not new, but now works using faster - responding
electric motors replacing the old hydraulic
system.
In contrast to the previous active
roll stabilization system, the anti-
roll bars are now no longer actuated hydraulically but by means of
electric swivel motors.
Audi has also introduced an optional

electric motor and a three - stage planetary gearbox that separates the two halves of the stabilizer bars.
