Seattle Space Needle event - Slate truck photos, impressions, answers

There is no reason to not expect the Slate can have good EPS.

While EPS 'can' have acceptably good feel and feedback, in practice such setups are the minority and typically relegated to traditional sporty cars rather than trucks and/or EV's. So statistically speaking, there is more reason to expect the EPS to be not-good than be good from a driver engagement standpoint.

That being said, in the Munroe video they did talk about enjoyable driving characteristics, so there is also some hop still.

Dorbiman: Thanks for the confirmation that the rep misspoke. I too sent a similar question and just received a similar reply.

I'd prefer EPS just for simplicity. Hydraulic power steering is basically a solved equation at this point, but given time all hydraulic systems will leak. Shit, the PS pump on my Silverado has been leaking for like 8 years. I should really get around to rebuilding it at some point.

If it can seep for a decade without affecting function, it's just adding corrosion protection... That's a feature, not a bug. LOL

Very true, the pump my 09 2500 went out, lost power steering and brakes.

Add me to manual steering. Simple, cheaper, and how much effort can it be? I'm an actual MAN.

But its all in the tuning. Just because a steering system is hydraulic instead of electric doesn't mean it magically has better feel and precision. The suspension system design, geometery, and alignment are just as important to steering feel and accuracy as are the power source and type of the application.

I brought up my Bronco as a case in point, it is an ORV that has great steering feel and precision. Two things that helps the Bronco is its independent double-wishbone, coil-over strut, front suspension, and coil on-shock rear suspension. Plus great tuning of the electric rack.

Road forces are inherently transmitted to the driver through a hydraulic rack assist, but can be engineered out with varying degrees of success.

Road forces are inherently isolated from the driver through an electric rack assist, but can be engineered in with varying degrees of success.

Across common suspension and spring/damper types, like double wishbone and coilover, which particular one is used has little inherent effect on steering feel and precision. The geometries that actually do affect steering feel and precision (KPI/scrub, caster/trail, camber, and toe) can be similarly applied across the board.

According to my calculations RE: ζ(2)=π2/6 and eiπ=-1

The actual answer is corned beef. You are welcome.
