Coming Soon in Your Next Truck (?)

I agree while it seems like a great idea and I'd love to see some innovation for EVs. They really glazed over the unsprung weight aspect. They're hanging a lot out of this on normal driving conditions. My issues with EV aren't normal driving conditions its cold weather performance and towing performance.
For trucks I think hybrid is the only way. The F150 lightening is terrible. But their hybrid option with the ecoboost seems decent. Gm has the best electric for towing but still you’re very mile limited even a 20% increase in efficiency will still be laughable for towing range.
So someone finally designed a small and efficient electric motor? Nice. Sounds like something my son would cook up.
But if the motor is small enough to fit within a wheel, and they're worried about unsprung mass, then why not just make the outer housing of the motor the wheel?

Tom that is a good thought, however. Can you guess how much a mount and balance would cost? And do we really want the average tire tech nowadays working with high voltage? They keep using the phrase "motor in the wheel" when they mean "motor in the hub". If the motor is the wheel how would the motor turn itself?
The outer shell covering the outside windings is what I was thinking.
This video is so filled with unrelated B roll it's almost unwatchable. And the AI voice ?
But in all seriousness, they just re-invented the axial flux motor. Everything that was described on what the team did to redesign the motor sounds just like a axial flux motor. And no, they didn't take over the world.
And I think they are way over estimating the losses in a traditional EV drive train. They are using figures closer to ICE losses. I would be surprised if an EV had more then 5% loss from motor to wheel
They are chasing the wrong problem with EV's. No matter how efficient they make the motor, the battery is still the weakest link. A few percent here and there isn't going to double the range or half the charging time
