In October of last year, China Society of Automotive Engineers annual meeting of the National Advisory Committee powerful strategy, Ouyang Ming Gao professor at Tsinghua University as a representative issued the "energy-saving and new energy vehicle technology road map" of concern, including lightweight technology , including The seven major directions of energy-saving vehicles, pure electric and hybrid vehicles, fuel cell vehicles, intelligent connected vehicles and automobile manufacturing, power battery technology, and automobile manufacturing technology are written into the technology roadmap.

In addition to better safety, plastic bumpers have many advantages. The bumper made of plastic is much lighter than the metal, which reduces the quality of the car and brings better fuel consumption performance. Moreover, the plastic bumper is not easy to rust, which is more convenient for later maintenance and maintenance. The cost of plastic materials is lower than that of metal materials, and cars are becoming cheaper and cheaper now, which has a lot to do with the improvement of car materials. The use of plastic bumpers reduces the cost of the car, which is also a good thing for consumers.

Replacing metal bumpers with plastics is actually a great change in automobile production technology, which not only reduces costs but also brings better safety, which is beneficial to both car manufacturers and consumers. .
