VW had a system called "synchro" which was some sort of fluid which changed viscosity as it heated up by the slipping action.
That's a viscous coupling. My Range Rover has one of those, too. You have to make sure you use them or they go solid.

My transit has "traction assist" which actually applies the brake on the side that's slipping, using the ABS pump.
Yeah, that's the Land Rover system. Ford swapped it for a transit engine, which goes into all the new Defenders.
