Abstract: Based on environmental protection and sustainable development requirements, all countries have mandatory and clear requirements for automobile energy consumption. How to reduce the energy consumption is one of the main research topics of the current major automobile enterprises. On the basis of the research related data combined with the current automobile development existing technology on the current market of the automobile emission reduction technology analysis and arrangement, this article mainly introduces the current market mainstream of five energy conservation and emission reduction way: body lightweight, improve the thermal efficiency of engine, adopt engine hybrid technology, develop energy recovery system and low wind resistance coefficient. The development of automobile consumption reduction technology requires the cooperation between different automobile enterprises, any enterprise cann't independently study a certain technology, and needs to explore different technologies at the same time. At present, China's automobile free brands are actively exploring related technologies, which will certainly drive the technological innovation and economic growth of China's automobile industry in the future.
