I took the new differential from the 42109 App-Controlled Top Gear Rally Car and compared it to the previous generations, also tried to see if there are any changes/improvements/benefits:

 

Good video thanks.

Interesting..... Looks based on what you covered the new one might have several advantages over the old....

Thanks for the Vid. Is it possible to flip the 28Z gear to make the Diff 3.5 wide?

@efferman it is not possible, the other side is different and you cannot connect the clips:

 

Thanks

I never realized the 4L diff could be combined with a driving ring for a locking diff, ill put that down to my dark ages putting a clean break between old studfull and new studless

On the topic of that diff though, AFAIK you can drive it perpendicularly, with the crown wheel, but i might be misremembering.

Good to see the new diff offers more versatility, both with the option for a diff lock and the option for both parallel and perpendicular drive, now it remains to be seen if lego will use this new diff in all sets requiring a diff, or just for the higher load applications like an RC car.

What is the part/s number/s for this new differential?

Got it from brickset. LBG 65414, Red 65413, & 5X tan 6589.

The full LEGO numbers are 6285646 & 6285647

So glad that they made a new diff design, I always found the old design to weak.

And very difficult to assemble 

I reckon you could shim the planetary gears with acetate sheet to increase the friction in this and make it semi-open.

Can you have axles with end-stop in the new diff. I mean with the end-stops inside the diff?

EDIT: At the red gear end I mean, the other end can only take an axle outside-in.

I just tested with 4L axle with stop, it has not enough space for the end stop collar. It would require significant power to assemble too, so I didn't forced.

It was a good thought, but would have lead to the next: how to integrate it in technic frames. :)

Thanks for testing this out @agrof!

There would have been less need to integrate them in frames ;-).
