Sedan Car

Generally, cars emphasize comfort and are passenger-centric. In addition, they choose engines with moderate horsepower, small displacement, and low fuel consumption based on economic considerations. The car body structure mainly includes: body shell, doors, windows, front sheet metal parts, interior and exterior trim parts and body accessories, seats, ventilation, heating, cooling, air conditioning, etc. Trucks and special cars also include boxes and other equipment. The body shell is the installation base for all body parts. It usually refers to the rigid space structure composed of the main load-bearing components such as longitudinal beams, cross beams and pillars and the sheet metal parts connected to them.
