It's well known that the main advantage of the electric steering system is power efficiency and its implications. It is also simpler than the hydraulic system. Why would a car manufacturer choose a system that shares the disadvantages of the hydraulic and electric systems, higher overall complexity and maybe price, to achieve a result similar to the electric? Why just not use purely electric steering in the first place?
And if the 'connection to the road' feeling of the hydraulic is so important for that specific car, why not use just the ordinary hydraulic system? Why add such complexity, inherent unreliability, and price?
