What is the difference between the electro-hydraulic steering assistance of Ford New Focus manual transmission and automatic transmission?

I really didn't notice that different models of the new Focus are equipped with different power steering! Then say the difference directly! I'm not very professional, that's probably what I mean anyway! Electronic power assist: it is very light to hit the steering wheel in situ. With the increase of vehicle speed, the steering wheel will become slightly heavier to improve driving stability and driving feel! Hydraulic power: whenever you hit the steering wheel, it's the same feeling! Personally, I think so. Electronic power assist may be adding a motor or controller or something, which is automatically controlled by a computer. When the car is not moving, it provides the greatest help. After the car is driving, the power is reduced according to the speed, so the steering wheel will feel heavier and heavier! Mechanical hydraulic power is anti-knowledge, without electronic controller, the power can not be changed at will, so it is the same feeling from getting on the bus to driving at high speed! ! ! This is probably the truth!
