B檔將引擎以不供油方式連結運轉以增加額外消耗能量(就是單純的浪費掉一些能量)
國外早期討論已久的技術文件指出
B到最高可提供30%的電能回收
相同條件下D檔則是肯定超過30%以上
但當你輕踩油門時,B和D檔的加速邏輯與運作會一模一樣
所以,當你希望更容易的掌握車輛的減速(尤其是在長下坡情境)
就可以選用B檔
但是,當你發現B檔出現異常噪音...勸您還是暫時切回D檔以煞車減速(selecting "B" ... will maximize regenerative efficiency and is useful for controlling speeds downhill. In "B" mode about 30% of the energy is recovered.
This is very misleading, because what it does *not* say is that in normal "D" mode with proper braking technique, considerably *more* than 30% of stopping energy is recovered! I think they meant "30% of the possible energy recovery" that would otherwise happen in "D" mode, but something got lost in translation.)
