不服输的中国新能源，貌似在这个领域输给了东南亚。 当腾势D9、理想MEGA等售价数十万的高端MPV在舆论场上狂飙突进时，一个冷冰冰的数据却显示，MPV在整个中国汽车市场的份额，已萎缩至区区 3.8%。 这个数字，差不多只有东南亚国家印尼的八分之一。 一个巨大的反差就此产生：为什么被称为"制造业狂魔"、"新能源摇篮"的中国，似乎卖不动MPV？ 这事其实很有意思，东南亚10万元以下的中低端MPV越是畅销，就越衬托出我们的被动。 就好比住在宫里的皇后，一旦去了农村，就可能被村妇们嘲笑"没吃过柿饼"一样戏谑。 因为中国的汽车保有量是3.19亿辆，市场基数大，消费结构成熟，千人汽车保有量是印尼、越南的3倍左右，是柬埔寨、老挝、缅甸的超12倍。 这意味着，如果单纯比较我们与东南亚的MPV份额，就像比较苹果和橘子谁的皮更厚一样没有意义。 我们的"苹果"，与东南亚的"橘子"，差距在哪里？ 在东南亚，以丰田 Avanza为代表的中低端MPV是载人拉货的全能选手，是坚挺刚需。 丰田 Avanza 而在中国，随着新能源产业不断向高端化挺进，只有GL8及以上的高端商务车，才更符合我们对MPV的期待。 中国人开商务MPV，那讲究可太多 ...
