Core Viewpoint - The article discusses the strategic choice of Great Wall Motors to adopt the Hi4 hybrid intelligent four-wheel drive technology system, which emphasizes efficiency, safety, and technological versatility in the context of the evolving Chinese electric vehicle market [2][6]. Group 1: Hi4 Technology Overview - Hi4, short for Hybrid Intelligent 4WD, is a hybrid electric drive platform developed by Great Wall Motors, integrating both electric and engine-driven capabilities [2]. - The Hi4 system is not a single technology but a family of versions tailored for different vehicle classes and usage scenarios, including basic, performance, urban off-road, extreme off-road, and heavy commercial vehicle variants [4]. - The Hi4 technology aims to provide a low-cost, low-energy, high-performance four-wheel drive experience, addressing the current market penetration challenges of less than 5% for four-wheel drive vehicles in China [5]. Group 2: Technical Advantages - Unlike range-extended electric vehicles, Hi4 combines parallel and series hybrid architectures, allowing for direct engine drive to the wheels, which enhances energy efficiency in mid to high-speed conditions [4]. - Hi4's design philosophy emphasizes energy path management, requiring advanced control logic, collaborative algorithms, and hardware adaptability, leading to improved durability and system load performance [4]. - The Hi4 system can intelligently switch driving modes without user intervention, optimizing performance based on driving conditions, which has been validated in the Wuling Blue Mountain model [5]. Group 3: Strategic Implications - The Hi4 system represents a significant technological evolution for Great Wall Motors, reflecting a shift towards a comprehensive "electric + intelligent + multi-scenario adaptability" technical logic [6]. - Great Wall Motors has achieved nearly full self-research and development for the Hi4 system, showcasing its capability to integrate various technologies from electric control algorithms to battery layout and chassis integration [6]. - The Hi4 technology is positioned as a critical battleground for Great Wall Motors in the hybrid market over the next five years, indicating its strategic importance for the company's future [6].
