Abstract：

Automotive lightweight is one of the main interests for the development of automotive industry, therefore, effective reduction on the weight of whole body is a direct and effective method to save energy and reduce emission. There are two main approaches expounded. One is to use the lightweight materials of high strength steel, aluminum alloy, magnesium alloy, plastics, composites, etc. The other is to use the advanced manufacturing processes such as hot forming, laser tailor-welded, hydro-forming, and so on. It was mainly introduced that the current research about the lightweight materials and the advanced manufacturing processes and their application in automotive lightweight technology, and the latest research development about new materials and technologies reviews were summarized. Then the hot spot problems at home and abroad were put forward. Based on the above research status, the development trends about automotive lightweight technology in the future were proposed.
