Infineon and Subaru Expand Longstanding Technology Partnership to Power Next Generation ADAS and Vehicle Motion Control Systems

(IN BRIEF) Infineon Technologies AG and Subaru Corporation are strengthening their partnership to support the development of next-generation advanced driver assistance systems and vehicle motion control technologies in future Subaru vehicles. At the center of the collaboration is Infineon’s latest AURIX TC4x microcontroller, which will power Subaru’s integrated electronic control unit designed to coordinate advanced ADAS features and real-time vehicle control. The platform enables high-speed processing of sensor inputs from cameras, radar and other sources while supporting critical automotive safety standards up to ASIL-D. The companies have worked together on previous ADAS systems and plan to deepen their collaboration around in-vehicle computing and networking as the automotive industry transitions toward software-defined vehicles. Infineon has also reinforced its position in the microcontroller market through technology development and the acquisition of Marvell’s automotive Ethernet business, expanding its capabilities for centralized computing architectures in modern vehicles.

(PRESS RELEASE) MUNICH, 10-Mar-2026 — /EuropaWire/ — Infineon Technologies AG and Subaru Corporation are expanding their long-standing collaboration to support the development of advanced driver assistance technologies in future Subaru vehicles. The partnership centers on Infineon’s latest generation AURIX™ microcontrollers, which will power a new integrated electronic control unit designed to enhance both ADAS capabilities and vehicle motion control.

As driver assistance technologies become increasingly sophisticated, vehicle systems require faster and more reliable processing of sensor data and driving conditions. Infineon’s newest AURIX MCU generation strengthens the real-time performance of Subaru’s next-generation ECU, enabling the system to process large volumes of vehicle and sensor information more efficiently than previous platforms.

Peter Schaefer, Executive Vice President and Chief Sales Officer Automotive at Infineon, emphasized that dependable real-time operation is essential as advanced driver assistance technologies continue to evolve. He noted that Infineon’s AURIX microcontroller family is designed to provide the computing foundation required for accurate decision-making and coordinated vehicle control.

Subaru is currently developing an integrated electronic control unit intended to coordinate its next-generation EyeSight driver assistance technology with vehicle motion control systems. According to Eiji Shibata, Executive Officer and Chief Digital Car Officer at Subaru Corporation, Infineon’s AURIX MCU plays a critical role in enabling the system to fuse sensor inputs and manage vehicle control functions in real time. He highlighted that Subaru and Infineon have worked closely together for many years and have collaborated from the early stages of MCU development to optimize system performance.

Within the new ECU architecture, Subaru will utilize Infineon’s most advanced automotive microcontroller platform, the AURIX TC4x. This device strengthens both computing performance and in-vehicle networking capabilities and will act as the primary controller for next-generation ADAS functionality. The TC4x platform supports real-time sensor fusion by integrating data from cameras, radar systems and other sensors to deliver faster and more dependable driver assistance responses.

The AURIX TC4x microcontroller combines up to six processor cores operating at 500 MHz in lockstep configuration and is designed to meet automotive functional safety standards up to ASIL-D. This architecture supports high levels of reliability and safety for mission-critical automotive applications.

Infineon and Subaru have previously collaborated on Subaru’s current generation of driver assistance systems. The companies intend to deepen their cooperation in areas such as in-vehicle computing and networking, aiming to accelerate the development of technologies that contribute to safer and more secure mobility solutions.

Infineon has also strengthened its broader position in the global microcontroller market. The company reached the number one position in automotive microcontrollers in 2023 and rose to the top spot across the overall microcontroller market one year ago. Since then, Infineon has continued to expand its technology portfolio to address future automotive requirements, including work to enable RISC-V as an open standard for automotive microcontrollers.

In addition, Infineon broadened its capabilities in vehicle networking through the acquisition of the automotive Ethernet business from Marvell in August 2025. This move expanded the company’s portfolio for centralized computing architectures in software-defined vehicles and reinforced its ability to provide integrated solutions for next-generation automotive electronics.

As part of their collaboration, executives from both companies will present at embedded world 2026 in Nuremberg, Germany. The joint session titled “Powering the future of ADAS and SDV together – Subaru and Infineon” will feature Eiji Shibata of Subaru Corporation and Peter Schaefer of Infineon and will take place on March 10 from 2:00 to 2:30 p.m. CET in hall 5, booth 5-210.

Infineon will also showcase its broader portfolio of technologies focused on decarbonization and digitalization during the event, which runs from March 10 to 12 at the Nuremberg Exhibition Centre.
