What is the difference between electromechanical steering and just regular power steering?

Question

I am not a car expert, so can someone explain the differences and benefits of each system? I know that electromechanical steering uses a motor instead of power steering fluid. What else is different? And why is that being used more now?

Answer 1

The reason the new system is being used more often is less parts and takes up less room in engine area.Older style power steering units are prone to leaks.
