How a Torsen differential works

There are many of different ways of making a differential system, and one of the more ingenious ways is the “Torsen” differential. Where the old basic version of a differential has big problems with wheels slipping on oil spills, ice and other slippery surfaces, the Torsen differential solves this conundrum in a beautiful mechanical way. Learn Engineering has made this excellent video that explains how it works, but this is a bit advanced. If you aren’t comfortable with how a basic differential works, you should first watch these videos, just to get your head around the mechanics:
