The vehicle body structure uses advanced high-strength steel (AHSS) and hot-formed steel. The hot-formed steel can reach a strength of over 1500MPa after being quenched at 950℃. It is used in key parts such as door anti-collision beams and A-pillars to effectively absorb energy in a collision and improve the safety of the whole vehicle. At the same time, lightweight aluminum alloy steel (aluminum-steel composite material) is used in the body panels to help reduce the energy consumption of new energy vehicles.
