Instruction: Describe the main areas of assembly in an automotive factory.

Response: A traditional automotive assembly has a number of process areas in order to produce a vehicle. The process begins with chassis assembly where the lower frame of the vehicle is welded. In parallel, the body shop produces the body shell which then moves to the paint shop to be painted. The painted body is then married with the chassis and interior components such as the engine, transmission, seats, and infotainment subsystems are assembled onto the vehicle. Lastly, the vehicle undergoes a quality assurance step to ensure the finished automobile functions as intended.
