后(hou)(hou)輪驅動（RWD）：豪華轎(jiao)車通常采用后(hou)(hou)驅，重量分配接(jie)近(jin)于(yu)50∶50，提供了(le)(le)更平穩的駕駛。RWD與FWD驅動情況正相(xiang)反(fan)，操控性(xing)能(neng)有(you)所(suo)提高。當加速時車身重心向(xiang)后(hou)(hou)轉移，這正是(shi)你所(suo)希望的，因為后(hou)(hou)輪主管牽引力，前(qian)輪主管汽車方向(xiang)。你還可以在彎道(dao)加速。這并不是(shi)說RWD在結構(gou)上就(jiu)好(hao)，它也存在缺陷，如從前(qian)到(dao)后(hou)(hou)的傳動軸(zhou)（使車內地板從前(qian)到(dao)后(hou)(hou)隆(long)起），還有(you)一個很大的差(cha)速器在后(hou)(hou)部(bu)，增加了(le)(le)重量和成(cheng)本，它同樣(yang)不適應全天候(hou)駕駛。
