Since the end of the 1980s, many automobile manufacturers in Europe, the United States, and Japan have cooperated with aluminum companies to strengthen research on aluminum automobile bodies and have achieved encouraging results. In 1995, the German Audi company first began to mass-produce aluminum bodies.

Aluminum matrix composites have low density, high specific strength and modulus, and good thermal fatigue resistance, but their application in automobiles is restricted by price and production quality control.

The main specifications of automobile models are continuously optimized. On the premise of retaining the main parameters of specifications, the structural strength of the whole vehicle is improved and the consumption of consumables is reduced.
