This shows how the EDS diffbrake system makes the car move out of this diagonal wheel spin. with only open differentials, one front and one rear wheel would spin, and even if the spinning front wheel got contact with the ground, so that both front wheels had traction, the car would NOT move without EDS, because the torsen center diff cannot transfer any torque if one of the axles loses traction completly, as if one rear wheel is off the ground like in this video, then that would be the only wheel that would spin, all others would stand still. So the EDS uses the brake to brake the spinning rear wheel so the other side that has all the weight also gets some torque and add a overall load to the rear axle, making the torsen transfer equal torque divided by the built-in Torque Bias Ratio (TBR) witch i guess is 1:3 on this car, so the front wheels gets the rear wheel torque divided by 3, witch makes the car move.

purpose is to explain the concepts and not be a Pixar-budget film.

Torsen Limited Slip Differential - Explained
How do Torsen limited slip differentials work? The Torsen differential is a
very unique type of LSD, which was invented by Vernon Gleasman in the
1950's. It allows for a ratio of torque split between the drive wheels, and
it allows for differing speeds of the drive shafts, much like a typical
LSD. It does so in a highly unique fashion.
