從未在廣州租車旅游過的(de)游客，對于應該怎(zen)么(me)(me)選擇(ze)租車的(de)車型一般(ban)不是很了解，在這里為您介紹一下怎(zen)么(me)(me)選擇(ze)劃算的(de)汽車來(lai)自駕游。

1、汽車越重越費油

從節油(you)觀(guan)點(dian)來看，汽車(che)自重(zhong)與油(you)耗(hao)成正(zheng)比關(guan)系(xi)，即重(zhong)量越大的(de)汽車(che)越耗(hao)油(you)，使用經(jing)濟性相對較(jiao)差。小型車(che)自重(zhong)每增加(jia)40公(gong)斤要多耗(hao)燃(ran)油(you)1%。但自重(zhong)大的(de)汽車(che)具備急轉(zhuan)彎和(he)急剎車(che)狀況下穩定性較(jiao)好(hao)的(de)優(you)點(dian)，不(bu)易(yi)發生“發飄”的(de)現象。

2、不(bu)同驅動方式的(de)利弊

根據動(dong)(dong)(dong)(dong)(dong)力(li)傳(chuan)動(dong)(dong)(dong)(dong)(dong)方式(shi)(shi)，汽車(che)(che)(che)(che)可分為“四輪驅(qu)動(dong)(dong)(dong)(dong)(dong)”，“發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)前(qian)(qian)(qian)(qian)(qian)置(zhi)(zhi)、后(hou)橋驅(qu)動(dong)(dong)(dong)(dong)(dong)”，“發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)前(qian)(qian)(qian)(qian)(qian)置(zhi)(zhi)、前(qian)(qian)(qian)(qian)(qian)橋驅(qu)動(dong)(dong)(dong)(dong)(dong)”，“發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)后(hou)置(zhi)(zhi)、后(hou)橋驅(qu)動(dong)(dong)(dong)(dong)(dong)”四種： 四輪驅(qu)動(dong)(dong)(dong)(dong)(dong)方式(shi)(shi)主(zhu)要(yao)用(yong)(yong)(yong)在(zai)一(yi)些越野車(che)(che)(che)(che)上，優(you)點(dian)(dian)使前(qian)(qian)(qian)(qian)(qian)后(hou)輪都(dou)有(you)驅(qu)動(dong)(dong)(dong)(dong)(dong)力(li)，牽引力(li)大(da)，通過性(xing)(xing)強，附著力(li)大(da)，穩定(ding)(ding)性(xing)(xing)好(hao)，車(che)(che)(che)(che)身和(he)傳(chuan)動(dong)(dong)(dong)(dong)(dong)系統(tong)的(de)(de)鋼板(ban)比(bi)轎(jiao)車(che)(che)(che)(che)厚(hou)、安全系數高，適于越野。但(dan)缺(que)點(dian)(dian)是重(zhong)(zhong)量(liang)大(da)，節油性(xing)(xing)差。發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)前(qian)(qian)(qian)(qian)(qian)置(zhi)(zhi)、后(hou)橋驅(qu)動(dong)(dong)(dong)(dong)(dong)方式(shi)(shi)主(zhu)要(yao)用(yong)(yong)(yong)在(zai)一(yi)些中(zhong)、高級轎(jiao)車(che)(che)(che)(che)上，優(you)點(dian)(dian)是前(qian)(qian)(qian)(qian)(qian)后(hou)橋承載的(de)(de)負(fu)荷(he)基本一(yi)樣，動(dong)(dong)(dong)(dong)(dong)力(li)性(xing)(xing)強，牽引力(li)大(da)，在(zai)爬坡(po)(po)(po)、泥濘道(dao)路(lu)和(he)顛簸路(lu)上行駛時(shi)，動(dong)(dong)(dong)(dong)(dong)力(li)性(xing)(xing)、防后(hou)輪側(ce)滑(hua)和(he)穩定(ding)(ding)性(xing)(xing)明顯優(you)越于“前(qian)(qian)(qian)(qian)(qian)置(zhi)(zhi)前(qian)(qian)(qian)(qian)(qian)驅(qu)動(dong)(dong)(dong)(dong)(dong)”的(de)(de)汽車(che)(che)(che)(che)。但(dan)其(qi)缺(que)點(dian)(dian)是傳(chuan)動(dong)(dong)(dong)(dong)(dong)軸退至后(hou)橋，導(dao)致地(di)板(ban)凸起，幾個總成分開布置(zhi)(zhi)，占據空間較大(da)，很難使汽車(che)(che)(che)(che)小型(xing)化。發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)前(qian)(qian)(qian)(qian)(qian)置(zhi)(zhi)、前(qian)(qian)(qian)(qian)(qian)橋驅(qu)動(dong)(dong)(dong)(dong)(dong)方式(shi)(shi)主(zhu)要(yao)用(yong)(yong)(yong)在(zai)中(zhong)小型(xing)汽車(che)(che)(che)(che)上，優(you)點(dian)(dian)是省(sheng)了(le)(le)傳(chuan)動(dong)(dong)(dong)(dong)(dong)軸，地(di)板(ban)平(ping)坦，傳(chuan)動(dong)(dong)(dong)(dong)(dong)系緊湊，重(zhong)(zhong)量(liang)減(jian)輕，地(di)板(ban)降低，重(zhong)(zhong)心下(xia)(xia)降。但(dan)其(qi)缺(que)點(dian)(dian)是上坡(po)(po)(po)時(shi)重(zhong)(zhong)量(liang)向后(hou)移(yi)，前(qian)(qian)(qian)(qian)(qian)橋負(fu)荷(he)減(jian)輕，不(bu)能(neng)產生足夠的(de)(de)牽引力(li)，在(zai)較滑(hua)的(de)(de)路(lu)面上因(yin)前(qian)(qian)(qian)(qian)(qian)橋重(zhong)(zhong)量(liang)不(bu)夠而產生不(bu)了(le)(le)足夠的(de)(de)牽引力(li)；下(xia)(xia)坡(po)(po)(po)時(shi)前(qian)(qian)(qian)(qian)(qian)橋負(fu)荷(he)過重(zhong)(zhong)，特別(bie)是在(zai)下(xia)(xia)坡(po)(po)(po)剎車(che)(che)(che)(che)時(shi)前(qian)(qian)(qian)(qian)(qian)橋負(fu)荷(he)會進一(yi)步(bu)加重(zhong)(zhong)。這種車(che)(che)(che)(che)型(xing)不(bu)宜(yi)在(zai)上下(xia)(xia)坡(po)(po)(po)較多的(de)(de)山區使用(yong)(yong)(yong)。發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)后(hou)置(zhi)(zhi)、后(hou)橋驅(qu)動(dong)(dong)(dong)(dong)(dong)方式(shi)(shi)主(zhu)要(yao)用(yong)(yong)(yong)在(zai)微(wei)型(xing)車(che)(che)(che)(che)上，優(you)點(dian)(dian)是省(sheng)了(le)(le)傳(chuan)動(dong)(dong)(dong)(dong)(dong)軸，附著力(li)大(da)，牽引力(li)也大(da)，軸距較小，地(di)板(ban)下(xia)(xia)沒有(you)排氣管(guan)，發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)廢(fei)氣、噪音不(bu)會污(wu)染車(che)(che)(che)(che)廂(xiang)內(nei)。但(dan)其(qi)缺(que)點(dian)(dian)是后(hou)橋負(fu)荷(he)大(da)，轉彎易側(ce)滑(hua)，操縱系統(tong)太長，結構復(fu)雜，冷(leng)卻系統(tong)復(fu)雜，行李箱(xiang)太小。

3、自動檔(dang)汽車省(sheng)事不(bu)省(sheng)錢

自(zi)(zi)(zi)動(dong)檔(dang)(dang)（又(you)稱自(zi)(zi)(zi)動(dong)變速(su)）裝(zhuang)備有自(zi)(zi)(zi)動(dong)控制裝(zhuang)置，行車(che)中可根據車(che)速(su)自(zi)(zi)(zi)動(dong)調整檔(dang)(dang)位，無需(xu)人工操作，省去了許多換檔(dang)(dang)及踏踩離合的(de)(de)(de)工作。其不足之(zhi)處在(zai)于價格昂貴、維(wei)修費用很高，而(er)且使用起來(lai)(lai)比手動(dong)檔(dang)(dang)車(che)費油，因為自(zi)(zi)(zi)動(dong)變速(su)器的(de)(de)(de)動(dong)力傳遞是通過液壓來(lai)(lai)完成(cheng)的(de)(de)(de)，在(zai)工作中會造成(cheng)動(dong)力損失。尤其是低速(su)行駛或堵(du)車(che)中走(zou)走(zou)停停時(shi)，更(geng)會增大油耗。

4、選用裝配子午(wu)線輪(lun)胎的汽車

裝有子午線輪(lun)胎(tai)的(de)汽車與裝有斜交(jiao)輪(lun)胎(tai)的(de)汽車相比，耐磨(mo)性可(ke)以提高50%～100%，滾動阻力降(jiang)低20%～30%，而且可(ke)以節(jie)油6%～8%。

5、選用鋁(lv)臺(tai)金(jin)輪圈的汽車

目前(qian)鋁合金輪圈的(de)價格仍是鋼制輪圈的(de)2～3倍(bei)左右，但其使用的(de)效益也(ye)遠(yuan)高于鋼輪：

（1）質量輕，省油(you)；

（2）散(san)熱性能好，增(zeng)加(jia)輪胎壽命；

（3）真(zhen)圓度高(gao)，可以提高(gao)車輪運動精(jing)度，適合高(gao)速行駛；

（4）彈性好，提高車輛行駛中的(de)平順性，更易于吸收(shou)運(yun)動中的(de)振(zhen)動和噪音；

（5）可100%回收，屬環保(bao)產品
