Enthusiasts shun the EPS like a plague, suggesting that this setup robs feel and feedback. I don't disagree with this, as many EPS-equipped vehicles have very wooden and over-assisted steering and cases in point include the previous-generation Honda City and the Nissan Sylphy. However, the new BMW 5 Series uses EPS, and it seems to deliver a fine amount of feedback.
An interesting case is Hyundai. The i10 and i30 2.0 use EPS and both actually feel good to steer. In contrast, the new Sonata with hydraulic power steering did not feel as interactive.
Manufacturer claims EPS saves weight, power & FC by just tiny the few percent (3-5%) that can't even see nor feel the difference other than feelingless steering. If engine does not have proper valve timing control & variable air intake system will still guzzle fuel. Electric motor will not last longer than hydraulic rack & pinion actuator.
Talking about failsafe, without power especially battery's dead, the hydraulic power steering can still turn the car. Even if aux belt torn, the hydraulic power steering can still steer though feels heavy like Kancil's. No prob no worry on motor overheating or damage.
Besides, the auxiliary belt will still be there to pull A/C, alternator pulleys even with EPS. No harm having it to pull power steering pulley. Sonata YF using hydraulic power steering? That'll be great if it's true. I hope Altis 1.8E should retain d old hydraulic power steering for higher practicality.
