造车，原来也可以有“预制菜”？

Core Viewpoint - The emergence of "pre-made dishes" in the automotive industry, exemplified by CATL's "Rock Solid Chassis," signifies a shift towards platform-based vehicle manufacturing, enhancing safety, efficiency, and design flexibility [4][73]. Group 1: Pre-made Dishes Concept - The concept of "pre-made dishes" has gained traction in various industries, including food and automotive, with companies like Hema and Dingdong Maicai launching their own pre-made meal products [2][3]. - CATL's introduction of the "Rock Solid Chassis" represents a new approach in vehicle manufacturing, akin to pre-made dishes, allowing automakers to focus on design and innovation while relying on a standardized platform [4][73]. Group 2: Safety Features - The "Rock Solid Chassis" has undergone rigorous safety testing, including a high-speed collision test at 120 km/h, demonstrating its ability to protect occupants and prevent battery fires [9][12]. - The chassis employs a "biomimetic turtle shell structure" to distribute collision forces, enhancing safety during impacts [19]. - High-strength materials, such as 2000 MPa submarine-grade steel and 600 MPa aerospace-grade aluminum, contribute to the chassis's durability and safety [20]. Group 3: Design and Development Efficiency - The "Rock Solid Chassis" allows for significant design flexibility, enabling automakers to create various vehicle types using the same platform, thus reducing development time and costs [42][46]. - The integration of over 400 standardized interfaces facilitates communication between the chassis and various vehicle systems, streamlining the development process [44]. - The development cycle for new models can be reduced from three years to 12-18 months, with an estimated 5% reduction in overall vehicle costs [46][47]. Group 4: Technological Integration - The chassis incorporates advanced technologies, such as a high degree of integration for battery systems, allowing for improved energy density and extended vehicle range [67]. - The "Rock Solid Chassis" supports rapid charging capabilities, achieving charging rates of over 5C [68]. - The use of drive-by-wire systems enhances vehicle responsiveness and allows for customizable driving experiences [70]. Group 5: Industry Implications - The introduction of the "Rock Solid Chassis" reflects a broader trend in the automotive industry towards platform-based manufacturing, which is essential for adapting to the fast-paced evolution of smart vehicles [72][76]. - This shift indicates a changing relationship between automakers and component suppliers, with suppliers taking a more prominent role in driving technological advancements [81].
