從未在廣州租車旅(lv)游(you)過的(de)游(you)客，對(dui)于(yu)應該怎么選擇(ze)租(zu)車的(de)車型(xing)一般不是很了解，在(zai)這里為(wei)您介紹一下怎么選擇(ze)劃算(suan)的(de)汽車來(lai)自駕游(you)。

1、汽車越重越費油

從節(jie)油(you)(you)觀點(dian)來看，汽(qi)車(che)(che)自重(zhong)(zhong)與油(you)(you)耗成正比關系(xi)，即重(zhong)(zhong)量越大的(de)汽(qi)車(che)(che)越耗油(you)(you)，使用經濟性相(xiang)對(dui)較(jiao)(jiao)差。小型車(che)(che)自重(zhong)(zhong)每增加40公斤(jin)要多耗燃油(you)(you)1%。但自重(zhong)(zhong)大的(de)汽(qi)車(che)(che)具備急(ji)轉彎和(he)急(ji)剎車(che)(che)狀況下穩定性較(jiao)(jiao)好的(de)優(you)點(dian)，不易發(fa)生“發(fa)飄”的(de)現象。

2、不同驅動方式的(de)利弊(bi)

根據動(dong)(dong)(dong)(dong)(dong)力(li)(li)(li)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)方(fang)(fang)式，汽車(che)(che)可分(fen)為“四(si)輪驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)”，“發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)前(qian)置(zhi)(zhi)、后(hou)(hou)(hou)橋(qiao)(qiao)(qiao)(qiao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)”，“發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)前(qian)置(zhi)(zhi)、前(qian)橋(qiao)(qiao)(qiao)(qiao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)”，“發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)后(hou)(hou)(hou)置(zhi)(zhi)、后(hou)(hou)(hou)橋(qiao)(qiao)(qiao)(qiao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)”四(si)種： 四(si)輪驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)方(fang)(fang)式主要用(yong)在(zai)(zai)一(yi)些(xie)越(yue)(yue)野(ye)車(che)(che)上(shang)，優點使前(qian)后(hou)(hou)(hou)輪都有(you)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)力(li)(li)(li)，牽引力(li)(li)(li)大(da)，通(tong)過性(xing)強，附(fu)著(zhu)力(li)(li)(li)大(da)，穩(wen)定(ding)性(xing)好(hao)，車(che)(che)身和(he)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)系(xi)統的(de)鋼板比(bi)轎(jiao)車(che)(che)厚(hou)、安全(quan)系(xi)數高，適于越(yue)(yue)野(ye)。但(dan)缺(que)(que)點是(shi)重(zhong)(zhong)(zhong)量(liang)大(da)，節(jie)油性(xing)差。發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)前(qian)置(zhi)(zhi)、后(hou)(hou)(hou)橋(qiao)(qiao)(qiao)(qiao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)方(fang)(fang)式主要用(yong)在(zai)(zai)一(yi)些(xie)中、高級轎(jiao)車(che)(che)上(shang)，優點是(shi)前(qian)后(hou)(hou)(hou)橋(qiao)(qiao)(qiao)(qiao)承(cheng)載的(de)負荷(he)基本一(yi)樣，動(dong)(dong)(dong)(dong)(dong)力(li)(li)(li)性(xing)強，牽引力(li)(li)(li)大(da)，在(zai)(zai)爬坡、泥(ni)濘道路(lu)和(he)顛簸路(lu)上(shang)行(xing)駛時，動(dong)(dong)(dong)(dong)(dong)力(li)(li)(li)性(xing)、防后(hou)(hou)(hou)輪側滑和(he)穩(wen)定(ding)性(xing)明(ming)顯(xian)優越(yue)(yue)于“前(qian)置(zhi)(zhi)前(qian)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)”的(de)汽車(che)(che)。但(dan)其缺(que)(que)點是(shi)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)退至后(hou)(hou)(hou)橋(qiao)(qiao)(qiao)(qiao)，導致(zhi)地(di)板凸起，幾個總成(cheng)分(fen)開(kai)布置(zhi)(zhi)，占據空間較(jiao)大(da)，很難使汽車(che)(che)小型(xing)(xing)化。發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)前(qian)置(zhi)(zhi)、前(qian)橋(qiao)(qiao)(qiao)(qiao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)方(fang)(fang)式主要用(yong)在(zai)(zai)中小型(xing)(xing)汽車(che)(che)上(shang)，優點是(shi)省(sheng)了傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)，地(di)板平坦，傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)系(xi)緊湊，重(zhong)(zhong)(zhong)量(liang)減輕，地(di)板降(jiang)低(di)，重(zhong)(zhong)(zhong)心下降(jiang)。但(dan)其缺(que)(que)點是(shi)上(shang)坡時重(zhong)(zhong)(zhong)量(liang)向(xiang)后(hou)(hou)(hou)移，前(qian)橋(qiao)(qiao)(qiao)(qiao)負荷(he)減輕，不(bu)能產(chan)生足(zu)夠的(de)牽引力(li)(li)(li)，在(zai)(zai)較(jiao)滑的(de)路(lu)面上(shang)因(yin)前(qian)橋(qiao)(qiao)(qiao)(qiao)重(zhong)(zhong)(zhong)量(liang)不(bu)夠而產(chan)生不(bu)了足(zu)夠的(de)牽引力(li)(li)(li)；下坡時前(qian)橋(qiao)(qiao)(qiao)(qiao)負荷(he)過重(zhong)(zhong)(zhong)，特別是(shi)在(zai)(zai)下坡剎(cha)車(che)(che)時前(qian)橋(qiao)(qiao)(qiao)(qiao)負荷(he)會(hui)進一(yi)步加(jia)重(zhong)(zhong)(zhong)。這種車(che)(che)型(xing)(xing)不(bu)宜在(zai)(zai)上(shang)下坡較(jiao)多的(de)山區使用(yong)。發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)后(hou)(hou)(hou)置(zhi)(zhi)、后(hou)(hou)(hou)橋(qiao)(qiao)(qiao)(qiao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)方(fang)(fang)式主要用(yong)在(zai)(zai)微型(xing)(xing)車(che)(che)上(shang)，優點是(shi)省(sheng)了傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)，附(fu)著(zhu)力(li)(li)(li)大(da)，牽引力(li)(li)(li)也大(da)，軸(zhou)(zhou)(zhou)距較(jiao)小，地(di)板下沒有(you)排氣管，發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)廢氣、噪(zao)音(yin)不(bu)會(hui)污染車(che)(che)廂內。但(dan)其缺(que)(que)點是(shi)后(hou)(hou)(hou)橋(qiao)(qiao)(qiao)(qiao)負荷(he)大(da)，轉(zhuan)彎易側滑，操縱系(xi)統太長，結構(gou)復雜，冷卻系(xi)統復雜，行(xing)李箱太小。

3、自動檔汽車省(sheng)事不(bu)省(sheng)錢

自(zi)動檔(dang)（又稱自(zi)動變速(su)）裝備有自(zi)動控(kong)制裝置，行車(che)中(zhong)可(ke)根據車(che)速(su)自(zi)動調整(zheng)檔(dang)位，無需人工(gong)操作，省(sheng)去(qu)了許多換檔(dang)及踏踩離合的工(gong)作。其(qi)不足之處(chu)在于(yu)價格昂貴(gui)、維修費(fei)用(yong)很高，而(er)且使用(yong)起來比手動檔(dang)車(che)費(fei)油，因為自(zi)動變速(su)器的動力傳遞是通(tong)過(guo)液壓來完成的，在工(gong)作中(zhong)會造成動力損失(shi)。尤其(qi)是低速(su)行駛或堵(du)車(che)中(zhong)走走停停時，更會增大油耗(hao)。

4、選用(yong)裝(zhuang)配子午線輪(lun)胎(tai)的汽車

裝有子午(wu)線輪(lun)胎的(de)汽(qi)車(che)與(yu)裝有斜交輪(lun)胎的(de)汽(qi)車(che)相比，耐磨(mo)性可以(yi)提高(gao)50%～100%，滾(gun)動阻(zu)力降低20%～30%，而且可以(yi)節油(you)6%～8%。

5、選(xuan)用(yong)鋁臺金輪圈的(de)汽車

目前鋁合(he)金輪(lun)圈的(de)價格仍是鋼制輪(lun)圈的(de)2～3倍(bei)左右(you)，但其使用的(de)效益也遠高于鋼輪(lun)：

（1）質量(liang)輕，省油；

（2）散熱性能好，增加輪胎(tai)壽命；

（3）真(zhen)圓度高，可(ke)以提高車輪運動(dong)精度，適合高速行駛；

（4）彈性(xing)好，提高(gao)車輛行(xing)駛中的平順性(xing)，更(geng)易(yi)于吸收運動中的振動和噪音(yin)；

（5）可(ke)100%回收，屬環保(bao)產品
