Group 1: Suspension Development - The 2022 Li Auto L9 initially featured a single-chamber air spring and single-valve CDC, which received mixed reviews regarding its sportiness [10][12]. - In 2023, user feedback prompted the company to enhance the suspension's sportiness through an OTA update, introducing the "Sport Magic Carpet" mode alongside the existing comfort mode [14][20]. - The 2024 model upgraded to dual-chamber air springs, allowing for a 5% reduction in stiffness in comfort mode and a 30% increase in stiffness in sport mode, further differentiating the two driving experiences [21][33]. Group 2: Advanced Suspension Technologies - The introduction of dual-valve CDC in the 2025 model significantly improved the suspension's performance, providing faster response times and a wider damping adjustment range, which enhanced both comfort and sportiness [36][64]. - The dual-valve CDC allows for independent control of compression and rebound damping, resulting in a 50% increase in damping force, which improves vehicle stability during cornering and over uneven surfaces [68][72]. - The dual-chamber air spring system enables real-time stiffness adjustments, enhancing support during aggressive driving while maintaining comfort during normal conditions [35][36]. Group 3: User-Centric Design Philosophy - The company's approach emphasizes balancing comfort and sportiness, responding to user feedback to refine the driving experience [6][78]. - The evolution of the L9's suspension reflects a commitment to family-oriented comfort while integrating performance enhancements based on market demands [78]. - The article concludes that the ability to cater to diverse user preferences in suspension settings is crucial for customer satisfaction and product success [78].
