汽(qi)(qi)車(che)的驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)形(xing)(xing)式(shi)一(yi)(yi)般(ban)有(you)以(yi)(yi)下幾種(zhong)：前(qian)置(zhi)(zhi)后驅(qu)(qu)(qu)(FR)、前(qian)置(zhi)(zhi)前(qian)驅(qu)(qu)(qu)(FF)、后置(zhi)(zhi)后驅(qu)(qu)(qu)(RR)、中置(zhi)(zhi)后驅(qu)(qu)(qu)(MR)、四輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)。所(suo)謂驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)形(xing)(xing)式(shi)，是指(zhi)(zhi)發動(dong)(dong)(dong)(dong)(dong)(dong)機的布(bu)置(zhi)(zhi)方式(shi)及驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)輪(lun)(lun)的數量、位(wei)置(zhi)(zhi)的形(xing)(xing)式(shi)。國內外(wai)大(da)多數貨車(che)(含皮(pi)卡)、部(bu)分(fen)轎(jiao)車(che)(尤(you)其(qi)是轎(jiao)車(che))和部(bu)分(fen)客(ke)車(che)都(dou)采(cai)用(yong)前(qian)置(zhi)(zhi)后驅(qu)(qu)(qu)的驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)型式(shi)，但(dan)采(cai)用(yong)該(gai)型式(shi)的小型車(che)很少(shao)。所(suo)謂全(quan)(quan)(quan)輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)，又稱四輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)，是指(zhi)(zhi)汽(qi)(qi)車(che)前(qian)后輪(lun)(lun)都(dou)有(you)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)。一(yi)(yi)般(ban)用(yong)4X4或4WD來表(biao)示，如(ru)果你看見一(yi)(yi)輛車(che)上(shang)標有(you)上(shang)述字樣，那就表(biao)示該(gai)車(che)輛擁(yong)有(you)4輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)的功(gong)能(neng)。這種(zhong)總布(bu)置(zhi)(zhi)形(xing)(xing)式(shi)，由于全(quan)(quan)(quan)部(bu)車(che)輪(lun)(lun)都(dou)是驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)輪(lun)(lun)，充分(fen)利(li)用(yong)了汽(qi)(qi)車(che)的全(quan)(quan)(quan)部(bu)附著質量，因此汽(qi)(qi)車(che)有(you)較大(da)的驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和克服障(zhang)礙、防(fang)止打滑的能(neng)力(li)。所(suo)以(yi)(yi)，越野汽(qi)(qi)車(che)一(yi)(yi)般(ban)都(dou)采(cai)用(yong)這種(zhong)總布(bu)置(zhi)(zhi)形(xing)(xing)式(shi)。而(er)且(qie)，由于全(quan)(quan)(quan)輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)的汽(qi)(qi)車(che)有(you)較大(da)的驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)，加速性好(hao)(hao)，20世(shi)紀80年(nian)(nian)代以(yi)(yi)來一(yi)(yi)些轎(jiao)車(che)和旅(lv)行轎(jiao)車(che)也紛紛采(cai)用(yong)全(quan)(quan)(quan)輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)，成為(wei)所(suo)謂的“多用(yong)途(tu)運動(dong)(dong)(dong)(dong)(dong)(dong)車(che)（SUV）”，受到不(bu)少(shao)美國年(nian)(nian)輕(qing)人的喜(xi)愛(ai)，形(xing)(xing)成了'4WD'熱潮(chao)。但(dan)是，全(quan)(quan)(quan)輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)的結(jie)構復雜，成本高，在好(hao)(hao)路上(shang)行駛時燃料消耗大(da)，輪(lun)(lun)胎和機件的磨(mo)損(sun)大(da)。

維(wei)(wei)修費(fei)用(yong)低也是(shi)后輪(lun)驅(qu)動(dong)的(de)(de)一(yi)個優點，盡管(guan)由于(yu)(yu)構造和車(che)型的(de)(de)不同，這種費(fei)用(yong)將(jiang)會(hui)有很(hen)大的(de)(de)差別。但(dan)是(shi)如果你的(de)(de)變速(su)(su)器(qi)出了故(gu)障，對(dui)于(yu)(yu)后輪(lun)驅(qu)動(dong)的(de)(de)汽(qi)車(che)就不需要對(dui)差速(su)(su)器(qi)進行維(wei)(wei)修，但(dan)是(shi)對(dui)于(yu)(yu)前輪(lun)驅(qu)動(dong)的(de)(de)汽(qi)車(che)來說也許就有這個必要了，因為這兩個部件是(shi)做在(zai)一(yi)起的(de)(de)。不過經(jing)過幾十(shi)年的(de)(de)發(fa)展，前輪(lun)驅(qu)動(dong)汽(qi)車(che)的(de)(de)可靠性也已有了很(hen)大的(de)(de)發(fa)展，維(wei)(wei)修費(fei)用(yong)的(de)(de)高也許已經(jing)并不是(shi)一(yi)個大的(de)(de)問題(ti)了。

后輪驅動(dong)的(de)缺點也是顯而(er)(er)易見(jian)的(de)，比如相對高的(de)裝配和制造成(cheng)本(ben)，更多的(de)故障(zhang)，相對狹小的(de)室(shi)內空(kong)間等等。現在(zai)，更多的(de)汽(qi)車都是使用的(de)獨立后懸(xuan)掛系統，這樣(yang)設計師(shi)在(zai)設計時就可(ke)(ke)以將(jiang)車體與差速器(qi)和傳動(dong)軸靠的(de)更近(jin)，從而(er)(er)可(ke)(ke)以增大(da)室(shi)內空(kong)間。
