Most EPS numbs feedback from the wheels to the steering wheel.

Some EPS are so light even at high speed they are tiresome if not dangerous to drive.

If not implemented correctly, there may be noticable delay to steering weight change according to speed, ie: when decelerating from high speed, the steering weight does not lighten up accordingly, or conversely if you suddenly accelerate to high speed, the steering does not become heavier until a few seconds later. If you like to brake hard and accelerate hard, the steering weight becomes unpredictable.

However, most of the downsides may only matter if you always FnF. Like it or not EPS will replace all hydraulic power steering soon (word is the new Proton B-hatch aka GSC will be the first Proton car to use EPS), except for those hardcore sport cars, for example the Alfa Romeo 4C that doesn't even have power steering.

EPS is more efficient, yes. I believe it only assists (uses power) when you are actually needing it. HPS on the other hand always needs the engine to drive the hydraulic system (IINM), so the fuel consumption is higher.

Heavier steering at speed though? HPS can do that too. And usually HPS is more... involving IMHO. It just feels nicer, more direct, there is better feedback. There _are_ some EPS systems that work really well too, but they are rare, and it seems to be hard to get it right. I haven't driven any EPS car that I'd prefer over our HPS Citroen.

Sport sedan maa.
No engine and turbo sound cannot call sport car.

I think I see one top gear review where clarkson point out that the BMW he drive put fake engine sound from the speaker.

Don't think can compare proton with kimchi nor sushi car, as they are more tune towards comfort, city riding and good fuel economy.

Do check out this review on forte coupe. A comfortable, slow, mushy suspension, light steering make for a fail sport inspired car.

including golf gti...Peugeot rcz thp200.

like i said before..it depends on tuning. but mostly still shitty compared to hydraulics in terms of feedback and spirited driving.

regarding EPS & HPS

EPS, jazz petrol ckd
HPS, gen2

the EPS setting on jazz is nice, less heavy than gen2's HPS.

the EPS sometimes feel like Game Racing Steering Wheel (Logitech G27).

on long journey, the EPS need more attention(?).
(ok, i dunno whether this is due to Lotus handling or the steering system itself. on gen2, while moving, the steering is sturdy, while in jazz, the steering will move a bit a bit, then it need more attention in controlling the steering. at 1sttime, i found this to be tiring.)

can the EPS swap with playstation controller? hahahaha

i concerning on the safety & reliability of the EPS rather than talk about FC and weight...
will steering wheel will jammed & unmovable at all due to the failure of EPS motor? it is important especially while driving at road...

EPS can be heavy too as the feedback will create virtually from the motor...

Cerato supported to change driving mode (Normal, Sport and Comfort) depend on user preference...
but unsure whether support automatic mode or not depend on car speed...

this is i cannot comment.

my observation is, in jazzs' EPS u cannot turn the steering unless the engine is ignited, while in gen2's HPS u can move the steering hardly without the engine is ignited.

as for most electrical systems, Redundancy precaution must be there.

emm..since it's EPS, no Hydraulic Oil for Steering.

if redundancy wont be cheap, it should consisted of the motor, electric board, wire, sensor, space consumed, etc...
The reason going for EPS is light weight, space saving (no hydraulic system), cost reduction and capabilities of changes driving mode changes...

but still sometime analog (passive) based still wise choices if talk about safety...
if every devices changed to electronic (active) based are not a good idea AMO...
just like "chicken or egg" story...

then "cross-finger" la..ahhaha
