This paper introduces the use of new materials in the replacement of traditional materials in automotive vehicles. Firstly, the properties such as tensile strength, elongation at break, Young’s modulus, density were discussed and analyzed. Also, the benefits of using new materials are discussed by comparing the physical properties. Then the advantages of AZ91D magnesium alloy, T1000G carbon fiber were compared with traditional automotive materials and the improvements that were achieved where the new materials were proven to have increased strength and decreased weight. Furthermore, the concept of automotive lightweight is applied to demonstrate the relationship between new materials and fuel economy. Finally, the internal and external structures of the materials are analyzed such as the anisotropy of carbon fiber, and it was found that the benefits outweigh the drawbacks like the high production cost of carbon fiber, then suggestions are given for future investigations.
