This is a most excellent place for technology news and articles.
Fascinating, but in the video they very quickly swipe off-screen that the top speed their new system was able to achieve was 120 kph / ~75 mph.
I imagine something like this would have to be limited to vehicles that never need to approach speeds above that on a highway, so maybe busses or indoor shipping & receiving vehicles.
This is cool, but wouldn’t it make any tire issue an engine issue and this way more expensive and difficult to deal with?
EV already have much smaller gearboxes, because they don't need to shift.
Now they need 4 of them, not just 1.
Such a gain in weight :-)
I don't need video(s) to understand the subject here : I just use an image search :

This is a mechanical device that allows coupling of any wheels of any vehicles to any electric motor.
it is designed in such a way to permit vertical movement of the wheel without the need of such movement of the motor. So basically it is a new type of suspension.
Since it needs many gears in a row for the transit of mechanical energy it will incure an inefficiency factor.
