Feng Huang Wang· 2025-07-10 06:59
Core Viewpoint - Zeekr has officially unveiled its new flagship SUV model, Zeekr 9X, during the Haohan-S architecture and Zeekr 9X technology launch event, showcasing advanced technologies including "Haohan Super Electric Hybrid," "Haohan AI Digital Chassis," and "Qianli Haohan Intelligent Driving Assistance" [1][3]. Group 1: Powertrain and Performance - The Zeekr 9X features the Haohan Super Electric Hybrid system, which is a dedicated hybrid technology developed on a pure electric architecture, achieving a peak power output of 1030 kW (approximately 1400 horsepower) [3]. - All variants of the Zeekr 9X can accelerate from 0 to 100 km/h in under 3 seconds, with only a 0.2-second difference in acceleration time between fully charged and depleted states, ensuring consistent performance for users [3]. - The system is paired with a 2.0T hybrid-specific engine that boasts a thermal efficiency of over 46%, optimizing fuel economy while maintaining power [3]. Group 2: Chassis and Comfort - The Zeekr 9X is equipped with the Haohan AI Digital Chassis, which includes closed dual-chamber air suspension, CCD electromagnetic dampers, and a 48V active stabilizer bar, aimed at enhancing vehicle stability during high-speed cornering and overall driving comfort [4]. - The intelligent chassis has strong all-terrain adaptive capabilities, intelligently matching various complex road conditions such as deep snow and mud, and can control body deviation within 20 cm under 100 km/h crosswind conditions [4]. Group 3: Safety Features - The vehicle incorporates the "Haohan Safety Armor" body structure, achieving a torsional rigidity of 41600 Nm/degree, with over 91% of high-strength steel and aluminum alloy used in its construction [4]. - The launch emphasized four industry-first integrated structures, including an integrated hot-formed door ring and an integrated die-cast aluminum rear body, further enhancing passive safety performance [4]. Group 4: Intelligent Driving - The Zeekr 9X will debut the "Qianli Haohan H9" intelligent driving assistance system, featuring a unique five-laser radar perception scheme for 360-degree coverage [4]. - It is powered by dual NVIDIA Thor-U driving chips, providing a total computing power of 1400 TOPS, laying the hardware foundation for L3-level intelligent driving assistance [4]. - The system employs a unique "dual end-to-end large model" algorithm, supplemented by a safety adversarial model, creating a dual redundancy guarantee in its algorithms [4]. Group 5: Market Launch - The Zeekr 9X is set to officially start pre-sales at the Chengdu Auto Show at the end of August this year [8].
长城为何不做增程?详解Hi4背后的技术和战略逻辑

与传统意义上的混动不同,Hi4不仅具备电驱与发动机并行的混动能力,更重构了驱动逻辑,实质上是 一种以电为主、融合机械传动效率的技术体系。 在中国新能源汽车产业迈入智能化与电动化深水区的当下,动力技术路线的选择,不仅关乎产品体验, 也在重塑车企的技术底盘与品牌认知。 与越来越多自主品牌押注增程技术不同,长城汽车选择走另一条更具挑战性的路线——全场景智能四驱 电混技术体系Hi4。这个选择背后,是对效率、安全与技术普适性的权衡与押注。 Hi4,一种技术"矩阵化"的方式 Hi4,全称Hybrid Intelligent 4WD,是长城汽车构建的智能四驱电混平台。"H"代表Hybrid混动,"i"是智 能(intelligent),而"4"则明确指出其四驱能力。 这一点在搭载Hi4性能版的魏牌蓝山上已有验证。在日常使用场景下,无需用户介入,系统可智能切换 驱动模式——如起步时前后轮双电机输出,提高脱困与抓地能力;中高速巡航时则由发动机主导,以提 升能效。 对于消费者而言,Hi4带来的最大感知是四驱技术更为平民化和日常化,能耗降低、安全性提升,令四 驱不再是少数高端车型的专属配置。 Hi4体系并非单一技术,而是一个族群, ...
长城汽车回应为何不做增程:如果增程是“洗+甩”的洗衣机,Hi4就是“洗+甩+烘”

另外,长期以来,关于"日常用车四驱是否必要"的争议始终存在。有一部分用户认为,需要使用四驱的场景,在日常用车中占比小,不值得为了四驱额外付 出成本。但事实上,四驱车在部分复杂场景下,有更高的操控上限,安全性一般高于两驱车。 但吴会肖认为,随着城市内的地库、匝道、高架、停车楼越来越多,需要四驱的场景也越来越多,而且如今大家热衷自驾游,向往诗和远方,会更频繁地面 临户外复杂场景。在这样的背景下,四驱会愈发受到用户的重视,Hi4也将为推动四驱技术在中国持续普及,发挥至关重要的作用。 6月24日-6月26日,长城汽车"Hi4 Talk嗨聊会"开播。长城汽车CTO吴会肖及长城汽车技术中心副总经理王超,围绕用户对Hi4技术体系关心的问题进行了回 答。 在此次"嗨聊会"上,长城汽车再次对为何不做增程式电动车进行了回应。长城汽车技术中心副总经理王超表示,增程也叫串联,本质上是Hi4的一种运行模 式,即发动机只发电,不驱动。Hi4相比于增程,多了发动机直驱模式,在中高速场景下,这是一种更加经济高效的驱动模式。王超也拿洗衣机来生动举 例,如果说增程是"洗+甩"的洗衣机,那么Hi4就是"洗+甩+烘"的洗衣机,不仅功能更全,体验也更 ...
