力帆630簡介

2013年(nian)10月(yue)18日，力(li)帆(fan)汽(qi)車(che)在(zai)西藏拉薩舉行了力(li)帆(fan)630的上市儀式。力(li)帆(fan)630是力(li)帆(fan)620的升級(ji)版本，該車(che)同樣定位(wei)于緊湊型車(che)，但(dan)是定位(wei)要高于力(li)帆(fan)530。新車(che)變化(hua)也(ye)很明(ming)顯(xian)，尤其是在(zai)前(qian)臉部位(wei)。新車(che)采用“X”型前(qian)格(ge)柵，更(geng)具(ju)運動風格(ge)，頗有雷克(ke)薩斯最新家族式的感覺。前(qian)大燈燈角上揚，層次感分明(ming)。內飾方(fang)面，新車(che)在(zai)儀表盤以及中控臺的造型上也(ye)都有所調整。
