1. Design and Prototyping: The initial design and prototyping phase could take several months to a year or more. Engineers and designers would work on creating the car's blueprints, specifications, and mockups.
2. Manufacturing: Once the design was finalized, the manufacturing process would begin. This involved creating the various components and parts of the car, such as the chassis, engine, body panels, and interior elements. This could take several weeks to months, depending on the complexity of the car.
3. Assembly: The different components and parts were then assembled together. This was typically done by skilled craftsmen and mechanics, who would manually assemble the car using basic tools. The assembly process could take several days to weeks.
4. Finishing and Testing: After the car was assembled, it would undergo finishing and testing. This included tasks like painting, adding final touches, and conducting tests for performance, safety, and functionality. This phase could take several days or weeks.
Overall, the total production time for a single car in the old days could range from several months to a year or more. As manufacturing techniques and technology advanced over the years, car production became more efficient and the timeline for producing a single car gradually decreased.
