Did you know that with every turn of the wheel fuel is wasted?
By using electric steering, energy losses are reduced and improved steering is achieved. As you turn the wheel, a sensor judges the resistance and an electric motot is activated to give the necessary amount of assistance. There's no wasted energy since the electric motor is only activiated as needed. Fuel and space are saved by eliminating the hydraulic pump. Since the arrangement is controlled by electronic software, adding functions such as vibration supression to the steering wheel is easy.
