Comment on Behold The Hyundai Uni Wheel. Transportation May Never Be The Same

Trucks used these as far back as pre-WWII. It a great solution for off road vehicles to gain clearance. At low speeds, even universal joints work fine for this setup, because the shaft rotates at 1/3 wheel speed, like a drives haft does going into a differential.
This puts a diff at each wheel.

Not quite portal gears, that has the input shaft fixed at the top. This is like an adjustable portal gear.

Meh, it’s still a portal hub, where you put the input shaft is a minor difference. It’s still putting the gearset in the hub, increasing the total weight of the vehicle, and increasing unsprung weight.
Calling it a new thing is a lie. All they’ve done is switch it to planetary gears. I’d bet lots of money this was tried a long time ago, and was shelved in favor of an offset input shaft.
