There are two major approaches to lightweight design

1. Change the structure of auto parts to achieve the purpose of lightweight design. Through the improvement of the structure, the parts are thinned, hollowed, miniaturized and compounded, and then lightened.
2. Use lightweight materials, through the use of lightweight metal and non-metal materials, mainly high-strength steel, aluminum-magnesium alloys, engineering plastics and various composite materials for automotive lightweight design.
