I beleive the BMW system uses sensors to detect the motion and torque of the steering column and a computer module applies assistive power via an electric motor. Itr's not just an electrically-powered hydraulic pump. This allows varying amounts of assistance to be applied depending on driving conditions. A switch or program can switch between different assist curves (boost curve) or like on Audis, Volkswagens & the BMW Z4, the amount of assistance is automatically regulated depending on vehicle speed. BMW makes reference to varying steering response be programmable with the MMode settings.
