> Mass car production begins with design and engineering, then sourcing materials such as steel, aluminum and plastics. Sheets of metal are stamped into panels, which robots weld into a body-in-white; parts are also molded and cast. The body is painted, then the powertrain, wiring, interior and trim are added on the assembly line by robots and workers. Finished cars go through inspections and road tests before shipping. Around 90 million motor vehicles were produced worldwide in 2023. The footage shows car factories and assembly lines, with the presenter.

### Transcript

Cars are marvels of modern engineering, with each vehicle requiring a complex and intricate manufacturing process. Car production begins with the design and engineering of the vehicle, followed by the sourcing of raw materials such as steel, aluminum, and plastics. These materials are then formed into various components, including the chassis, body panels, and interior parts, through processes like stamping, molding, and casting. The components are then assembled on the production line where specialized robots, and skilled workers work together to build the vehicle. Finally, each car undergoes rigorous testing to ensure quality and safety standards are met before it is ready to be shipped to dealerships. With millions of cars produced each year, the automotive industry plays a significant role in economies around the world, driving innovation in the future. NOW YOU KNOW!
