這和我看到的資料一致。torsen是把打滑端的負載乘上一個倍數以後傳到另一端，打滑端如果完全沒traction，乘上倍數後還是幾乎沒有。這影片裡就是這樣使得A8的前軸沒力、沒辦法從自由輪中間脫出來。所以脫困的方法確實如外國人所說：含著煞車。
我看了一下wikipedia

的確是如上所述含著煞車 可以解決
When a Torsen differential is employed, the slower-moving wheel always receives more torque than the faster-moving wheel. The Torsen T-2R RaceMaster is the only Torsen to have a preload clutch. So even if a wheel is airborne torque is applied to the other side. If one wheel were raised in the air, the regular Torsens would act like an open differential and no torque would be transferred to the other wheel. This is where the parking brake 'trick' can help out. If the parking brake is applied, assuming that the parking brake applies even resistance to each side, the drag to the airborne side is 'multiplied' through the differential and TBR times the drag torque is applied to the other side. So the ground side would see (TBR X drag torque) minus drag torque, and hopefully that can help restore progress either forward/backwards. In Hummer/HMMWV applications, there are both front and rear torsen differentials, so use of the main brakes will operate this 'trick' on both axles simultaneously.
