Tang Jing, the leader of Li Auto's product lineup, shared an in-depth explanation regarding the rationale behind automakers' preference for aluminum alloy parts. He highlighted that in August 2024, there were widespread rumors suggesting that the suspension system of the Li L9 was not entirely made of aluminum, with critics labeling it as subpar and unsafe. Citing the Rolls-Royce Cullinan and BMW X7 as case studies, Tang illustrated that even high-end SUVs incorporate a blend of steel and aluminum in their suspension systems. He underscored that the primary motive for utilizing aluminum alloy parts is to reduce weight, a crucial consideration for new energy vehicles. The added heft from batteries and extra features makes it imperative to use aluminum to manage the vehicle's overall weight effectively. Tang further clarified that the proportion of aluminum in a car does not have a direct bearing on its safety or comfort levels. Therefore, equating a higher aluminum content with enhanced safety is a misconception that could misguide consumers.
