I just looked it up.
When the gas engine is off, the traction motor and generator spin at 250 rpm per MPH with stock tires.
You can do the math for your particular speed.
Enjoy!

That is all good to know. But what part of this says we should not flat tow our Maverick?
At their top speed a Tesla 3 traction motor is turning about 27,000 rpm. Now that sounds like a lot. But even if the Maverick IS turning 17,500 rpm at 70 mph...so what. It is designed to do that. Do NOT compare motor rpm to engine rpm. The forces at play are completely different.

Are you volunteering to flat tow 10,000 miles without running the engine in your hybrid?
Aren't you one of the people asking why you are supposed to run the engine every 6 hours?
Have you got it figured out now?

Why the hell would I drive it 10,000 miles without running the ICE? It is mandated to be started daily and every 6 hours during that day.
Frankly, I could care less WHY Ford directs me to do that, just like I don't care WHY Ford tells me to not exceed 70 MPH while towing it. I comply for the sake of my warranty and I have no reason to argue with Ford.
You seem to just want to argue peripheral issues.
The issues I question are found way back in the first post before you sent it sideways with extraneous issues. And they are extraneous, as Ford fully blesses flat-towing with few concerns to address...none of them regarding the speed that the transmission spins.
Here ya go:
1. Should the shifting be D to R to N as specified in the 2023 manual...or D to N as specified in the 2024 manual...and does it matter?
2. Do you really need to leave the truck in ACC mode for 3 minutes after putting it into NT as stated in the 2024 manual, but not in the 2023 manual.
Do you even have any experience flat-towing your Maverick? Do you work for Ford and know why the instruction was changed?

I understand what you are asking and I can sympathize with your confusion.
The fact Ford did not issue a TSB or CSP or any official communication on this leads to a logical, reasonable conclusion that the order does not matter and the primary benefit is achieved by running the engine every 6 hours or fewer.
They issued warnings about 6 engine fires. Seems unreasonable they would not issue warnings if Two-Thirds of the manuals were wrong and it mattered.

I sold the first Ford Escape Hybrid that came to my dealership. One of the first that came to Houston. Customer bought another from me about 3 years later. Must have been around 2005 or so.
I have sold many, I have also watched closely for any problems over the years with batteries or the Hybrid transmission. Let's just say I was more than welcome in the shop and had access to details on stuff like this.
Yet I cannot remember ANY motor failures. None. Not in flat tow applications ( easy to detect a flat tow vehicle by the base plates mounted in front when they come in...) or any other.
So I guess I also have 19 years or so of hybrid "experience".
But I don't add the EXPERT moniker as I am not a factory trained hybrid transmission expert. Nor do I tell people that they should not flat tow their Maverick. There is simply TOO MUCH history based on many years of flat towing Ford Hybrids to say there is ANY reason to expect harm or failure due to whatever RPM the motors are turning in flat tow usage. Ford is quite happy to approve that rpm and does NOT limit how many miles you can go. While this may be exactly what the 70 mph limit is all about, and I will add there must be something to do with the 6 hour "exercise", there is still NO data saying the motors are harmed by 17,500 rpm for hours on end. Again, that is more than common in industrial applications.
Under flat tow there is little load on any internal parts. They are not driving the vehicle. For all I know, the motors may have sealed bearings that don't require external lubrication, and all the gears are going to get substantial splash lubrication.
There are places in the US where when you start downhill you might run 10 miles on electric drive. ICE may not run in all that time. You will have a load on drivetrain, yet if only lubed when ICE is running why is there no damage from this. I will add to this the Cmax Energi that had a similar transmission, yet was capable of over 50 miles and never starting the engine.
We need to worry less about the motors, they will be just fine.

Probably so.
But look at how many people "freak out" over choice of oil, filter, tire pressure, and oil change intervals.
It's 100% capable to be flat towed.
It's just not a typical neural tow.
The steps are, well, not-user foolproof and there have been a few; albeit few major screw ups posted here that caused damage, that may have been user error. But it seems remarkably easy for users to error.
