GTI eDiff review
 

Went camping with my younger son and took the GTI up/down this road

It has super tight switchback, 10 and 25mph.

Diff is pretty impressive, no more 1 wheel drive with it. Still drives like fwd but just with full 2 wheel traction. Interesting since I cannot feel it working, basically transparent. I think a standard lsd you can feel when they lock up.
