Initially, plastics were primarily used for interior components such as door panels, dashboards, and seats. These plastics were often considered a cheap substitute for traditional materials like leather and metal. However, the development of new plastics with improved performance and design capabilities changed that perception.

In the 1960s, General Motors introduced the first plastic-bodied vehicle, the Pontiac Fiero. The car's body panels were made of a type of plastic called sheet-molded composite (SMC), which was light, durable, and resistant to corrosion. The use of SMCs marked the first time plastics were used for exterior car parts on a large scale.

Throughout the 1970s and 1980s, advancements in plastic technology led to increased usage in other areas of the car. Plastics were used for fuel tank components, bumpers, and even engine parts. One of the most significant uses of plastics came with the development of airbags. Initially designed to be contained within the steering wheel, airbags were made possible by using durable and flexible plastic materials.

In recent years, plastics have become an essential component in the automotive industry, with over 50% of car parts made of plastic. Plastics are used to create lightweight car parts, reducing the overall weight of the car and increasing fuel efficiency. With environmental concerns growing, the trend is to use more eco-friendly and sustainable plastics in the automotive industry.

Overall, the historical use of plastics in the automotive industry started with interior components, but the development of more advanced plastics has led to increased usage in exterior components and engine parts. The trend is to create lightweight and sustainable materials for automotive components, making plastics a fundamental material in the industry moving forward.
