依我看torque vectoring...(恕刪)
Haldex 完全放鬆還是有牽引力的,因為多片離合器之間有油,而且也無法片與片之間完全不碰觸到, 8R 這特系統,我也看不出有何設計在放鬆時片與片之間能確保有空隙,而且空隙間沒有油

Second generation[7] – 2001
The second generation of Haldex coupling is an electronically controlled permanent 4x4 system with a Haldex differential calculating how much drive should be directed to the rear wheels. The Haldex system automatically distributes power between the front and rear wheels depending on slippage, but normally sends 95% of the power to the front wheels.
V代的分離後最小動力傳輸一時找不到資料了,不過從機械設計來和,離合器片之間沒加壓,但空隙無法保持隔開,而且空隙之間有點油,總面積也不小的狀況下, 我認為阻尼,以及常常偶發輕微接觸而產生的牽引力,不可能為0
8代那個設計也是一樣.
