即使其它方面只是相同或略好一些，只要能使车辆的效率提高到现在的４－８倍，就会有助于许多问题的解决，诸如空气质量、油料使用、陈旧的产业结构，以及能源（特别是电力）供应等大问题，运输生产技术的变革具有成为世界环境与经济发展重要源泉的潜力．革命性的开发已经在主要的汽车制造国家进行．这些技术变革也为其它国家的大踏步发展提供了一次机遇．
Even if the other aspects are just the same or slightly better, as long as the efficiency of the vehicle is increased by 4-8 times now, many problems such as air quality, fuel use, outdated industrial structure, and energy ( Especially electricity) supply and other major issues, the transformation of transportation and production technology has become the world’s environmental and economic development an important source of potential. Revolutionary development has been carried out in major automobile manufacturing countries. These technological changes also provide an opportunity for the great strides of other countries.
