Discussion of the development of vehicle's lightweight technology

Over the past decade, the world automobile industry was faced with three major issues： energy, pollution and safety. At this stage, the world are very much concerned about the lightweight technology of automotive, for the energy crisis and environmental issues have become increasingly prominent. From the automotive＇s lightweight infaction on the energy, environment and vehicle＇s performance, research ideas of vehicle＇s lightweight technology were pointed out. The overview and function of vehicle＇s lightweight technology in the world were introduced. Now, using condition and performance of the lightweight vehicle＇s materials also were introduced. By analyzing the confronting problem of the development of vehicle＇s lightweight technique, the suggestions of how to develop the projected of vehicle＇s lightweight technology were proposed.
