本报(chinatimes.net.cn)记者刘凯 北京报道

2026年一季度,国内汽车产销同比分别下降6.9%和5.6%,纯电增速明显放缓。在此背景下,广汽集团于4月12日集中发布星源动力、星舰车身、星河智舱、星灵电子电气架构4.0及车规级芯片生态五大技术。与以往单一技术发布不同,此次覆盖动力、车身、座舱、架构和芯片的全栈方案,意图在存量市场中建立新的竞争支点。

广汽集团总经理閤先庆对《华夏时报》记者表示,面对价格战、流量战的喧嚣,广汽选择“把科技扎进土里,把用户装进心里”,坚定落实“番禺行动”。他透露,今年第一季度集团整体汽车销量同比增长2.38%,其中自主品牌增速达42.89%,海外市场销量增幅超过86%。“这份成绩单证明改革方向是正确的。”閤先庆说。

混动技术再扩容

广汽此次动力系统的核心看点,聚焦于“星源动力”技术品牌的正式成型。早在2025年,广汽已率先发布星源增程技术,而星源插混与星源超级双擎的亮相,让这一技术品牌完成补位,正式构建起覆盖增程、插混、油电混动的全域混动矩阵。

其中,星源插混的目标用户群体锁定在中大型SUV市场。广汽动力总成BU负责人祁宏钟介绍,搭载GMC 3.0混动变速器雷霆版后,系统最大输出扭矩突破6700Nm,整机扭矩密度达54.57 Nm/kg,广汽方面称这两项关键指标均稳居行业首位。

与星源插混相呼应,星源超级双擎的核心突破直指传统油电混动的痛点。传统油电混动车型受限于小电池容量,熄火后空调、哨兵模式、对外供电等常用功能均无法使用。广汽针对性配备5.4kWh高倍率安全电池,峰值放电功率达150kW,较上一代产品提升87.5%。祁宏钟对记者表示,这一技术突破让油混车型拥有了与纯电车同级的智能化体验,推动油混从“功能机时代”迈入“智能机时代”。

汽车行业观察员赵永琪对《华夏时报》记者表示,从政策环境看,2026年起新能源汽车购置税已从免征调整为按5%税率征收,这一变化直接凸显出油电混动车型的成本优势。广汽此时加码油混技术,客观上是在纯电与燃油之间搭建缓冲地带。

动力技术之外,车身技术的突破同样是本次科技日的重点。调研数据显示,国内SUV用户城市通勤占比超87%,65%用户有非铺装路面出行需求,超七成用户认为现有SUV存在使用妥协。对此,星舰车身采用了嵌入承载式大梁与多元环笼结构。据广汽车身研发负责人章恒介绍,星舰车身可以达到整车扭转刚度38000Nm/°,弯曲刚度42000N/mm,扭转刚度约为传统越野车型的4倍。A柱采用2200MPa级热气胀管梁,顶压能力12.2吨,是国标要求的 2.7 倍。

芯片国产化与架构升级

从车身结构到动力系统,广汽的技术突破覆盖整车硬件层面,而真正决定未来竞争格局的,仍是电子电气架构与芯片生态的自主掌控。在行业淘汰赛加速的节点,广汽在这两大领域的布局,既是自身破局关键,也折射出自主品牌核心技术自主化的突围之路。

中汽协数据显示,2025年我国汽车产销突破3400万辆,连续17年全球第一,新能源汽车销量1649万辆、渗透率47.9%。但繁荣背后,电子电气架构与车规级芯片“卡脖子”问题依然突出。为此,广汽推出了星灵电子电气架构4.0。据广汽研究院智能网联技术负责人梁伟强介绍,该架构实现智驾、座舱、动力、底盘、车身和车联网六域融合,采用3nm制程芯片,算力较上一代提升1.5倍。低时延确定性通信技术支持万兆以太网,智驾与底盘响应时间降至2毫秒,比人反应速度快50倍,OTA升级时间从30分钟压缩至8分钟。梁伟强透露,星灵架构4.0将于今年第三季度正式量产,逐步覆盖广汽主流车型。

芯片生态方面,广汽披露了“汽车芯片应用生态共建计划”的阶段性成果。2020年“缺芯”潮曾导致汽车行业大面积停产,过去一年AI算力需求爆发再次引发全球芯片供需失衡。工信部赛迪研究院数据显示,国产汽车芯片自给率仅约5%。对此,广汽方面称已联合105家生态伙伴,开发近400款芯片。梁伟强表示,这些成果将向全行业开放共享,赋能轨道交通、低空经济、具身智能等新兴领域。

在赵永琪看来,智能座舱已成为自主品牌的标准竞赛场。高通骁龙8295芯片、端侧大模型等配置在20万元以上车型中逐渐普及,行业同质化现象突出。广汽的技术指标虽处于主流水平,但软件迭代速度和生态丰富度仍需市场检验。

综合来看,广汽此次科技日展示了较为完整的自主研发体系。閤先庆表示,广汽近期在集团内部组建了全新的动力总成BU和智能座舱产品线,目的是从“技术驱动”迈向“用户驱动”。他援引张雪机车在世界超级摩托车锦标赛夺冠的例子,表示“中国能造出世界顶尖的发动机”,广汽将继续以自主研发造全球用户的好车。
