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

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

It replaces the cv joint. Watch the video.

The video shows how their gears go up down and side to side to perform the function of a cv joint. So whatever that cv looking thing is, it's not a cv joint.

If it was just a solid axle going from the motor to the uniwheel you couldn't steer the car. It doesn't allow for such movement.

Looks like it eliminates the engine-side cvd but not the wheel-side.

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

Anyone remember the Hyundai debacle where the transmission gears stripped mid-drive? Yeah..... I'm not trusting their gear-making ability (or lack thereof) with precision gears inside all of my wheels. Pass.
