RANGE ROVER中的ROVER (罗孚) 是北欧的一个民族,生产自行车时就使用罗孚作商标名。1904年生产汽车,仍以“罗孚”为车牌名。由于罗孚民族在历史上是一个勇敢善战的海盗民族,所以罗孚汽车商标采用了一艘海盗船,张开红帆象征着公司乘风破浪、所向披靡的大无畏精神。罗孚民族的名字其实也对应了rover的释义“漫游者”。
RANGE ROVER则是指“在广阔区域漫游的越野车”。
RANGE ROVER背景
ROVER (罗孚)是北欧的一个民族,LAND ROVER生产自行车时就使用罗孚作商标名。1904年生产汽车,仍以“罗孚”为车牌名。由于罗孚民族在历史,上是一个勇敢善战的海盗民族,所以罗孚汽车商标采用了一艘海盗船,张开红帆象征着公司乘风破浪、所向披靡的大无畏精神。这个民族的特征其实也对应了rover的释义“漫游者”,那转移到车上,什么样的漫游者才算是刚劲的越野车呢 我们已经了解了range的动词词源义是“在某一区域内活动” R ANGEROVER则是指“在广阔区域漫游的越野车”,这与其中文名“路虎揽胜”正好契合
