So in short, this adds suspension directly to the wheel, at the cost of higher maintenance? That's it?

I cannot think of a car company I'd trust less to do this than Hyundai/Kia.

Article made it sound like only front wheel drive exists now and that only front wheel drive cars use CV joints lol.

Honestly I don't care at this point, I won't buy anything from Hyundai.

so the pretty much only upside compared to hub motors is less weight in the wheels, and comared to conventional drivetrain layouts there's added complexity and slight extra interior space? i mean innovation is key, but i don't quite see the upsides as much as the hyundai engineers.

This is pretty cool!

But, in the video there is a quick flash of text that went away after 1s, 120km/h max speed?

From a mechanical standpoint, the new bearing saves a nearly negligible amount of space. Splitting the motor up and moving it to the notoriously wasted wheel well space is what clears up the center of the frame. Still very cool. It's basically a single output differential, which is already quite compact. No need to split the rotation for turning since the wheels rotation will no longer be mechanically linked.

I don't get what this does or what's the benefit. There's still a cv-joint there. Otherwise the wheels can't turn

I was just learning about CVJ gearing the other day and was thinking cars should use it instead of fixed gear ratios. Very cool.
