EHPAS (Electro Hydraulic Power Assisted Steering)
The system has a hydraulic pump driven by an electric motor. The electric motor is controlled by the
control module. The control module adapts the servo power based on the speed of the car and how fast
the steering wheel is being turned.

Blah blah blah mind glazes over

80 AMPS!! :shock:
8x12=96... That's almost a sodding kilowatt :shock: :shock:

I've no idea what sort the yoyo has, I know it's electric (bah du ba bah) but I thought it was connected to a hydrollick pump like the first one in the picture. Hold on a mo... now I bother to look there's a motor on the steering column (that's not available separately I note). I thought it felt ok but now of course it won't... :roll:

Don't see any fundamental reason why it can't behave as well as any other system.
All it needs is a talented software/drives application engineer that can actually drive a car instead of a playstation
2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)

The last couple of new Hire Cars I've driven have had horrid steering, very light with no 'feel' but that seems to be what we want/are given now :frown:
Cars in my care:
2021 Kia Spottage 1.6 Pez Turbo Dual Clutch Gearbox Trickery
2013 Renner Twingo - donkey work

It's almost as though "they"'re trying to remove all elements of enjoyment from motoring. Which I guess is the point :(
