Arm Horizon drives the intelligent transformation of automobiles with HSD and Journey 6P

                                                                                                         Arm Horizon automotive-grade chip assisted driving system

Recently, Horizon Robotics held its 2025 product launch event in Shanghai, introducing its L2 urban assisted driving system - Horizon HSD. This not only showcased its leading technological strength but also profoundly interpreted the industrial development trend of the accelerated popularization of automotive intelligence, making it a vanguard of the Shanghai Auto Show. Horizon Journey 6P, as the technical foundation, provides powerful and rich computing resources for the urban driver assistance system (HSD). Arm's powerful CPU computing capabilities provide crucial support for the Journey 6P to efficiently handle complex computing tasks. Arm is committed to empowering chips and OEM partners through advanced computing platforms, helping to enhance the performance and reliability of automobiles, and thereby bringing users a smarter, safer and more convenient driving experience.

Build the foundation of assisted driving technology with outstanding performance and reliability

Today, intelligent technologies such as advanced driver assistance systems (ADAS), intelligent human-machine interaction, and in-vehicle infotainment (IVI) systems are profoundly revolutionizing the automotive driving experience. In this transformation, Horizon HSD is emerging as a new solution for building a new generation of urban assisted driving.
The Journey 6P computing solution equipped on HSD is designed for the next-generation urban assisted driving, integrating rich computing resources such as CPU, GPU, and MCU, with a computing power of up to 560 TOPS. A single chip can support the full-stack computing tasks of urban assisted driving. Arm technology injects powerful computing power support into the Journey 6P solution, enabling it to efficiently handle complex algorithms and real-time data tasks. Among them, the functional safety design of Arm Cortex-A78AE covers a hybrid critical architecture, hardware-level safety mechanisms, and core splitting and step-locking technologies, which can efficiently meet the safety requirements of assisted driving. These features not only build a high-performance and highly reliable technical foundation for Horizon Journey 6P, but also facilitate the evolution of assisted driving technology towards efficiency and safety.

Horizon HSD will be launched globally on the Exeed brand as an advanced solution of Chery's "Falcon", along with the Journey 6P computing solution, and is scheduled to enter mass production in September 2025. To date, Horizon has achieved over 8 million sets of pre-installation mass production and shipment, more than 200 mass-produced and launched models, and over 310 mass-produced and designated models, accompanying over 5 million car owners on safe and pleasant travels.

Behind this set of impressive data, Arm technology has provided strong support. From the Journey 2 to Journey 6 series of assisted driving computing solutions, Horizon Robotics has maintained close technical cooperation with Arm, empowering multiple models from manufacturers including SAIC, Chery, BYD, GAC, Geely, Volkswagen, Li Auto, and NIO. It is worth mentioning that the new model of NIO's Firefly brand, equipped with Horizon's Journey computing solution, has been officially launched recently and has become a highlight of this year's Shanghai Auto Show. The close collaboration between Arm and its partners has not only driven the rapid evolution of assisted driving technology but also witnessed the prosperity of the automotive industry.

Arm technology is constantly evolving, building the computing power foundation for future automobiles

In the automotive field, Arm has been dedicated to investment for over two decades, continuously promoting technological evolution, and its technology has always led the development of industry applications. Today, Arm AE IP, which combines outstanding performance, scalability, energy efficiency and unique security functions, has become the cornerstone of automotive electronic products and continuously emempower leading automotive Oems at home and abroad. In the AI era, to meet the market's demand for high automotive computing power and performance levels, Arm has introduced server-level Neoverse cpus into the Arm AE IP product line. A brand-new automotive-specific CPU - Arm Neoverse V3AE - has been created, specifically designed for use cases such as high-end ADAS and intelligent driving that require ultra-high single-thread performance. This is also the first time that Arm has brought the Armv9 architecture into automotive applications, enabling the industry to benefit from the advantages of the new generation of Arm architecture, such as AI, security and virtualization functions.

This year, Arm will also launch the Automotive Computing Subsystem (CSS), providing pre-integrated and verified AE IP configurations for the partner ecosystem, further optimizing performance, power consumption and chip area.

With its expertise in energy efficiency, performance and functional safety, continuous technological evolution closely aligned with industry trends, and close collaboration with ecosystem partners, Arm's market share in the automotive sector has been continuously growing. At present, 94% of the world's automakers have adopted Arm technology in their latest models. When it comes to specific scenarios, Arm technology has supported 80% of IVI systems and 65% of ADAS systems.
Arm believes that the future of automotive technology lies in creating solutions that seamlessly integrate edge computing, Internet of Things functions, and AI. Arm will continue to join hands with the extensive automotive ecosystem to provide scalable, efficient and secure solutions for the automotive industry, and jointly unlock the potential of the AI era.
