ECARX and Arm signed a non-binding MoU on 2 November 2026 to explore AI computing platforms, extending work through SiEngine that has produced millions of automotive chips since March 2023, ECARX said. In an announcement issued from London, the Nasdaq-listed automotive technology company described a framework for joint research and product definition with Arm.
Key points
- The non-binding MoU covers joint engineering, including architecture, software, safety and validation work.
- ECARX says the partners will explore computing platforms for vehicles and other physical AI applications in China and global markets.
- ECARX says millions of SiEngine SE1000 chips have been produced since March 2023; development of the 5nm SE2000 platform is under way.
ECARX and Arm set out engineering work
The memorandum covers work on system architecture and performance optimisation, ECARX said. The partners also plan software enablement, functional safety work, and validation of toolchains and cybersecurity. Those activities would feed into product definitions for computing platforms intended to handle AI workloads in vehicles and other applications.
ECARX said the companies would explore configurations for deployment in China and other markets. Arm’s proposed role includes supporting ECARX as it works to bring the resulting compute products to market. The agreement sets out areas for co-engineering and exploration rather than binding product commitments.
Ziyu Shen, ECARX’s founder and chief executive, said the companies’ teams would work on a joint technical roadmap and co-engineering. He described the planned platforms as an extension of the companies’ automotive work through SiEngine, with potential uses beyond vehicles.
Drew Henry, Arm’s executive vice-president for physical AI, said the proposed work would bring together computing, software and safety requirements. Arm sees an opportunity to explore computing approaches for AI-defined vehicles and other autonomous systems, he said.
ECARX looks beyond vehicle computing
Mobility remains the starting point for the proposed platforms. ECARX said the partners would also consider uses in other industries involving physical AI, while Arm’s Drew Henry pointed to other autonomous systems. The memorandum therefore extends the scope of their work beyond the automotive products on which their existing collaboration has centred.
ECARX sells hardware and software for vehicles, including computing platforms, cockpit technology, driver-assistance systems and connectivity. The company says its technology is deployed in more than 12 million vehicles worldwide. It also says it works with 18 automakers and 28 vehicle brands.
That installed base gives ECARX an existing automotive business for the joint work. The cross-industry applications described in the announcement are prospective: ECARX and Arm said they would explore how to configure platforms for those uses. Shen said the companies would examine opportunities for deployment outside the vehicle market.
SiEngine’s SE1000 precedes the SE2000
The companies’ previous collaboration includes SiEngine, an automotive semiconductor company. ECARX said SiEngine has supplied its 7nm SE1000 automotive-grade system-on-chip platform to vehicle manufacturers. Mass production began in March 2023, and millions of units have since been produced and deployed, according to ECARX.
That production history is the closest operating comparison ECARX gave for the proposed AI computing work. The SE1000 is an existing automotive chip platform, while the memorandum covers exploration and joint product definition across a wider set of applications. ECARX said development of SiEngine’s next-generation 5nm SE2000 system-on-chip platform is under way.
