Fifth whell vs belt driven additional engine

[Staska]

I think, i have found an answer to my question. Some time, in the past i was helping with smart conversion with motorbike motor. Guys were using self made, roller chain diff.





It would be much cheaper than lexus or e-awd rear diff, and will propel car stand-alone. What would you comment ? roller chain diff/vs 5 wheel ? And for this setup, i am thinking of more serious motor - 5-8 kw, maybe some etek.

Here you have even more variants of chain driven diff.
