ECARX and Arm sign MoU to develop high-performance AI platforms

ECARX Limited and Arm today announced that they have signed a non-binding Memorandum of Understanding (MoU) on 2 November 2026 to jointly explore and develop next-generation high-performance AI computing platforms for mobility and broader cross-industry applications ^[1].

Key facts * The MoU establishes a framework for advanced solution development, including joint R&D and product definition ^[1]. * ECARX and Arm will engage in co-engineering activities spanning system-level architecture, performance optimisation, software enablement, functional safety, toolchain, and cybersecurity validation ^[1]. * The partners intend to explore tailored configurations for deployment across China and global markets ^[1]. * The collaboration builds on a history of partnership involving SiEngine, which has produced millions of units of 7nm SE1000 platform automotive-grade SoCs ^[1].

What do the partners aim to achieve? ECARX and Arm intend to unlock meaningful advances in performance, power efficiency, and scalable deployment for global customers ^[1]. Arm will support ECARX to bring to market highly-optimised compute solutions purpose-built to handle demanding physical AI workloads ^[1].

Who can use these new platforms? The new platforms are intended for deployment in mobility and broader cross-industry physical-AI applications ^[1]. The collaboration combines Arm's compute architectures with ECARX's full-stack automotive capabilities to build scalable high-performance compute for next-generation intelligent vehicles ^[1].

What is the history of this collaboration? The partnership builds on a long-standing collaborative relationship between ECARX and Arm, including work through SiEngine ^[1]. SiEngine has delivered advanced 7nm SE1000 platform automotive-grade SoCs to global OEMs, with mass production beginning in March 2023 ^[1]. Development of the next generation 5nm SE2000 SoC platform is also currently underway ^[1].
