Core Viewpoint - The development history of Li Auto's air suspension system is closely linked to the evolution of air suspension technology in China, highlighting the significant impact of local innovation and adaptation in the automotive industry [1][7]. Group 1: Historical Context and Development - The launch of the L9 in June 2022 marked a pivotal moment, as it was the first instance of a domestic air suspension system being mass-produced and standardized in China [3][4]. - Prior to the L9, domestic air suspension systems had not been produced in large quantities, with suppliers like Konghui only providing around 10,000 sets in 2021 [3][6]. - The failure of a German air suspension during a test drive prompted a shift towards domestic solutions, leading to a rapid development and improvement of local air suspension technology [4][8]. Group 2: Market Performance and Growth - In 2022, Li Auto sold 5.9 million sets of air suspension, while Konghui and Baolong sold 50,000 and 39,000 sets respectively, indicating a growing domestic market share [6]. - By 2023, Konghui's sales surged to 250,000 sets, making it the leading supplier, while Li Auto's sales reached 325,000 sets, reflecting a significant increase in domestic production and adoption [6][7]. - The trend continued into 2024, with Konghui and Li Auto maintaining strong sales figures, further solidifying their positions in the market [6][10]. Group 3: Technological Advancements - Li Auto's L9 was the first to feature a domestically produced single-chamber air spring, overcoming several technical challenges that had previously hindered mass adoption [9][10]. - The company also took control of the air spring calibration software, which had been previously managed by German engineers, showcasing a shift towards self-reliance in technology [9][10]. - In 2024, the introduction of a dual-chamber air spring in the L9 marked another milestone, further enhancing the vehicle's performance and control [10]. Group 4: Strategic Decisions and Management - A critical decision by the management to abandon reliance on a problematic German supplier in favor of domestic production was pivotal in the success of Li Auto's air suspension systems [22][24]. - The collaboration with Konghui involved intensive efforts from both companies, with teams working around the clock to resolve technical issues and ensure quality [24]. - The management's decisive actions during challenging times exemplified the importance of leadership in navigating supply chain and production challenges [24].
