未来的技术发展将以动力总成三个方向的结合为标志:首先是高科技小型化内燃发动机;其次是混合动力;再者就是带蓄电池和燃料电池的零排放车辆。
The future technological development will be marked by a combination of three powertrains: the first is the high-tech small-scale internal combustion engine; the second is the hybrid; and the second is the zero-emission vehicles with batteries and fuel cells.
