The only E-steering equipped vehicle I've owned was a 2007 Chebby Cobalt.
I didn't mind it. Outside the car it's just a simple grease filled manual steering rack, similar to what you'd find years ago on a no power steering FWD econo-box. Inside, above your feet is the servo motor that provides 'assist' to the input shaft. Simple aside from the electronics and electrical load. That's the way it was on the Slobalt anyway...
You can see why manufacturers are going to this; No pumps, hoses, oil, oil reservoirs, drag on the engine, clutter in the engine bay, etc.. BUT, more electrical load.
I'm kind of surprised Subaru hasn't gone this route with the new Impreza the way they want to squeeze every MPG out of it as possible.
I guess it's just the slow way Subaru adopts new technology. Just the way I likes it.
