1. On Oct. 1, Chinese automaker Seres Group and Huawei Technologies announced a five-year agreement to form a dedicated team and deepen their partnership around their flagship electric vehicle brand, Aito, just two weeks after appearing headed for a breakup [para. 1][para. 2]. On Sept. 15, the companies had abruptly overhauled their partnership, with Seres moving to reclaim operational control over product planning, design, marketing, retail sales, and customer service — areas long managed by Huawei [para. 3]. While the October pact brought both sides back together, people familiar with the matter said critical questions of operational governance and retail control remain unresolved [para. 4].
2. The rapid reversal highlights mounting friction within Huawei's automotive ecosystem. Huawei's brand cachet and retail network made Aito a breakout hit, but Huawei's aggressive expansion with competing state-owned carmakers diluted Aito's exclusivity, while steep supplier fees and slowing sales weighed on Seres's balance sheet [para. 5]. More broadly, the dispute illustrates an industrywide reckoning in China's competitive EV market, where automakers question whether leaning on a dominant tech partner justifies the financial toll and surrender of corporate independence [para. 6].
3. Following the mid-September rift, Seres executives moved to steady market sentiment, with Vice President Kang Bo insisting Aito remained an anchor of Huawei's Harmony Intelligent Mobility Alliance (HIMA) and Chairman Zhang Xinghai affirming the automaker would continue standing "shoulder to shoulder" with the tech firm [para. 8]. The alliance had saved Seres once before — originally a low-profile maker of commercial micro-vans, the company partnered with Huawei in April 2021 after an early EV pivot stumbled, ceding sweeping control over product definition, styling, and distribution [para. 9]. Maintaining that privileged position required significant capital: in July 2024, Seres spent 2.5 billion yuan ($373.5 million) to acquire Aito-related trademarks and patents, and a month later committed 11.5 billion yuan for a 10% stake in Huawei's new automotive software unit, Yinwang [para. 10].
4. Internal succession dynamics also accelerated Seres's push for autonomy, as Chairman Zhang gradually transferred operating responsibilities to his 37-year-old son, Zhang Zhengping, who took charge of the core Aito manufacturing business in June 2026 [para. 11]. Local industrial policy added further pressure — Chongqing Mayor Chen Xinwu visited Seres in late September amid the corporate maneuvering [para. 12]. The risks of going solo quickly became apparent when presales for the new Aito M8 fell noticeably short of past launches fronted by Huawei's star marketeer Richard Yu [para. 13].
5. At the core of the dispute is Aito's diminished exclusivity. Huawei expanded HIMA to include Chery, BAIC BluePark, JAC Motors, and SAIC, while Yinwang struck product-definition partnerships with GAC and Dongfeng for additional brands Qijing and Yijing [para. 16]. In March 2026, when HIMA announced its advanced 896-line lidar would debut on flagship Aito models, GAC's Qijing revealed the identical hardware just one day later [para. 17]. Seres recorded a net loss of 1.72 billion yuan in the first half of 2026 after posting profits in 2024 and 2025, and vehicle sales dropped 17.7% year-on-year to 227,000 units in the first nine months of 2026 [para. 18][para. 19].
6. Huawei's commercial terms compound these headwinds. Under the HIMA model, carmakers bear extensive expenses including component procurement, software licensing, development fees, and sales commissions — in the first half of 2026, Seres recorded 8.47 billion yuan in selling expenses, 14.7% of revenue, versus Li Auto's 8.9% sales and administrative expense ratio [para. 21][para. 22]. Rising raw material prices for lithium carbonate, memory chips, copper, and aluminum have further narrowed margins, adding roughly 14,000 yuan to production cost per vehicle [para. 23]. Meanwhile, competitors are developing alternatives to avoid supplier lock-in: Changan unveiled an in-house assisted-driving system with Horizon Robotics, and ByteDance's Volcano Engine deployed its Doubao AI assistant in SAIC's Roewe vehicles [para. 24].
7. To preserve its technical edge and pricing power, Huawei is looking to autonomous driving. China's mandatory safety standard takes effect in July 2027, alongside draft revisions to the Road Traffic Safety Law [para. 27]. Yinwang CEO Jin Yuzhi said success demands extensive R&D budgets, safety capabilities, and vertical integration, with Huawei estimating that computing infrastructure alone will require 70-80 billion yuan in capital investment over five years [para. 30]. Huawei aims to secure market share in rolling out Level 3 systems before repeating the model at Level 4, and is exploring robotaxi technology [para. 31]. Yet technological milestones may not resolve underlying frictions — automakers remain wary of compromising margins and brand identity, and whether the new five-year agreement delivers sustainable profitability for Seres remains an open question [para. 32][para. 34].
