ECARX and Arm signed a non-binding MoU on next-generation vehicle AI compute

ECARX and Arm announced on November 2 that they had signed a non-binding Memorandum of Understanding to jointly explore and develop next-generation high-performance AI computing platforms for mobility and for broader cross-industry applications. ECARX Holdings Inc. furnished the release to the Securities and Exchange Commission as an exhibit to a Form 6-K the same day, signed by chief financial officer Dylan D. Jeng.

Under the MoU the two companies said they would advance joint co-engineering spanning system-level architecture definition, performance optimization, software enablement, functional safety, toolchain and cybersecurity validation, and ecosystem build-out. They also said they would explore configurations tailored for deployment across China and global markets, addressing uses in mobility alongside broader cross-industry physical-AI applications.

The release placed the agreement on an existing relationship running through SiEngine, which it described as having delivered 7nm SE1000 platform automotive-grade system-on-chips to global original equipment manufacturers, with millions of units produced and deployed since mass production began in March 2023. Development of a 5nm SE2000 platform is under way.

Ziyu Shen, ECARX’s founder and chief executive, said the companies’ teams would now advance joint technical roadmap definition and co-engineering. Drew Henry, Arm’s executive vice president for physical AI, said physical AI required compute, software and safety “to work together from the ground up.”

ECARX also distributed the release through PR Newswire and posted it on its investor-relations site, and Arm’s newsroom listed it as partner news the same day. No financial terms, customer, vehicle program or timetable were given, and the MoU is described in the release itself as non-binding.
