Yes, Active Steering includes Servotronic, which varies assist by vehicle speed, rather than engine revs. There will be lighter steering at lower speeds, and heavier steering at higher speeds.

However, the biggest aspect of Active Steering is the fact it actually alters the steering ratio based on vehicle speed. Essentially, a 90° turn of the steering wheel at 20km/h will yield a greater wheel angle than the same 90° turn at 120km/h.

The combination of the two makes for the best of both worlds: At low speeds, the steering is light and quick. At moderate to higher speeds, the steering firms up considerably and the steering response is slower for greater directional stability.
