On the wiring harness... I'd love to see 48V, but you can do a smaller harness at 12V. They key improvement in the wiring harness is not the voltage, but the controller architecture. They're doing the Rivian and Tesla thing and going to zonal architectures. That means instead of 60 domain controllers, each containing software written and owned by a supplier, they are going to 4 to 7 multi-domain controllers, hopefully with software written and owned by Ford.

Think of a domain controller as a seat module. It has the electronics to control the seat. And another domain controller for the windows. And another for the locks. And on and on. As opposed to a zonal controller, which controls everything in a quadrant of the vehicle. So one controller does seats, windows, locks, and a dozen other things. Proper zonal architecture, together with smart system-engineering, lends itself to taking a lot of wires out of the vehicle. Ergo a simpler and shorter wiring harness.

I can tell you as a Maverick owner that a modern OTA zonal electrical architecture with OEM software is something I wish I had. Wish the Slate had it, but I understand they couldn't afford it. My Maverick had to go through 4 driveway updates. It took Ford months to negotiate with the suppliers about who was at fault, who would fix, what the fix was, and who would pay. Then a tech had to come to my driveway and spend an hour flashing the controllers in question. As opposed to Rivian or Tesla, where you wake up in the AM and have a message saying "Hey, we just fixed your rear view camera software while you slept".

What 48V brings to the party is lighter wires, not shorter wiring harnesses. The cost for 48V is that it's not yet the standard. So it can cost more, and you have a smaller supplier base to select from. Hopefully 48V will find it's way into the fleet. But it's gotta pass the cost-benefit calculation first.

But with no electrics for mirrors, seats, or windows and no infotainment module, is there a real need for domain controllers in a zonal architecture in the first place?

Right, because the earth is still warming from the last ice age. If you are trying to discuss gasoline cars related to anthropogenic climate change, what you call "widespread fact" is really propagated by the... media, which is my point.

I can see you are quite confused. Just watch the news.

And when the earth begins to cool again, you will blame... what?

Another riveting and productive conversation on this forum! Love to see it.

Oh, the irony!

I didn't see any winkies, so I gather you're serious.

Consider this: The "news" narratives are created by the wealthy and powerful (so far inarguable) who seek a Transfer of Wealth from you to them (also hard to argue against).

If you're watching the "news" to avoid becoming confused you're riding for a fall.

Fortunately Independent Media now has a foothold and is becoming increasingly relevant.

I watch around 50 YouTube sites from Poland, Germany, France, Britain, the US and others. There will be no fall.

Aside from higher profits on bigger vehicles, there is a kind of a loophole in emissions laws that helped drive manufacturers away from small trucks. Below a certain weight, the trucks had to meet a tighter emissions standard, and larger vehicle could pollute more. So trucks and SUVs and crossovers all got big enough to not be held to the tight standard, and the small trucks, and many compact cars and sedans died out. Notice what Ford no longer builds besides small trucks?

It's a bummer really. Domestic automakers have basically handed that entire segment of the market to foreign autos. Chevrolet doesn't even have a section for Cars anymore. They used to. The only "car" they make now is the Corvette. The only car Ford makes is the Mustang. Dodge only makes the new Charger.
