I'm having a hard time looking for a source on how a twin-clutch AWD system works. Can somebody explain it or point me to a good source? Is a twin-clutch AWD system the same as a limited-slip? Or is a limited-slip exclusive to a solid rear axle vehicle? Schematics? My friend who is a car guy is asking me these questions but he lives in the land of 90's solid axels. sorry, this should be in the technical section but I can't change it now.
