The actual cost of building a car mainly includes about 15% of intellectual property costs (such as patented body, patented technology, paid use of brand, etc.), actual manufacturing costs (steel, spare parts processing, purchase, etc. ) 45. Management costs and labor costs (company operating costs, average worker wages, burden per vehicle) 15. Equipment operation and depreciation (various automobile manufacturing equipment operation and depreciation costs) 15. After-sales service and logistics costs (Including car dealer profits, brand promotion expenses, advertising expenses, transportation expenses) 10. Especially for large automobile manufacturing companies, their brand value and technology patent fees often account for a very high proportion of vehicle manufacturing expenses. As for the costs in the actual manufacturing process you mentioned, they only account for about 45% of the actual vehicle manufacturing costs. The proportion for joint venture automobile companies is even lower, because joint venture automobile companies pay higher foreign manufacturing license and patent fees. As for the proportions of the body, engine, and chassis, they are even more negligible. They can only be counted as one-third of the 45%.
