What material is the exterior shell of the Wuling Hongguang Mini made of?

The exterior shell of the Wuling Hongguang Mini is made of sheet metal, which provides a certain level of safety. However, regular maintenance is still required. Car Maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as car servicing. Currently, car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other related components. Car Body: The primary function of the car body is to protect the driver and create an optimal aerodynamic environment. A well-designed body not only enhances performance but also reflects the owner's personality. In terms of structure, car bodies are mainly divided into two types: body-on-frame and unibody.
Last time when I got my Hongguang MINI repainted, I specifically asked the repair technician about the car's body materials, and it's quite interesting. The body frame uses high-strength steel plates to ensure safety, but the front and rear bumpers, which are prone to scratches, are made of engineering plastic. The doors and hood are still steel, but non-load-bearing parts like the roof and rearview mirror shells use lightweight materials. This combination helps control the overall weight to improve range, and in case of minor scratches, replacing plastic parts isn't costly. Last time I scraped the rear bumper while reversing, and replacing it only cost a few hundred yuan.
Having studied the material combination design of the Hongguang MINI, its lightweight approach is quite practical. The main body structure uses high-strength steel to ensure crash safety, while non-critical parts like bumpers, wheel arches, and mirror housings employ modified polypropylene plastic. This material offers good toughness and light weight, with the ability to rebound automatically after minor collisions. Once, during a rainy-day skid against a guardrail, the plastic bumper only cracked slightly without deformation, saving significant repair costs. The roof section uses lightweight alloy to further reduce weight, which greatly aids in improving the electric vehicle's range.
