Recently, Horizon held its 2025 product launch conference in Shanghai, introducing the L2 urban driving assistance system—Horizon HSD. This event not only showcased its leading technological strength but also profoundly interpreted the industry development trend of accelerating the popularization of automotive intelligence, becoming a precursor to the Shanghai Auto Show. The Horizon Journey 6P serves as the technological foundation, providing powerful and rich computing resources for the urban driving assistance system HSD. Arm’s powerful CPU computing capabilities offer critical support for Journey 6P to efficiently handle complex computational tasks. Arm is committed to empowering chip and OEM partners through advanced computing platforms, enhancing vehicle performance and reliability, thereby providing users with a smarter, safer, and more convenient driving experience.
Building a Technological Foundation for Driving Assistance with Excellent Performance and Reliability
Today, advanced driver assistance systems (ADAS), intelligent human-machine interaction, and in-vehicle infotainment (IVI) systems are profoundly transforming the driving experience. In this transformation, Horizon HSD is becoming a new solution for constructing the next generation of urban driving assistance.
The HSD, equipped with the Journey 6P computing solution, targets the next generation of urban driving assistance, integrating rich computing resources such as CPU, GPU, and MCU, with computing power reaching 560 TOPS, capable of supporting full-stack computing tasks for urban driving assistance. Arm technology injects powerful computing capability support into the Journey 6P solution, aiding in the efficient processing of complex algorithms and real-time data tasks. Among these, the functional safety design of the Arm Cortex-A78AE encompasses mixed-criticality architecture, hardware-level safety mechanisms, and lock-step technology, effectively meeting the safety requirements of driving assistance. These features not only build a high-performance and high-reliability technological foundation for Horizon Journey 6P but also assist in the evolution of driving assistance technology towards efficiency and safety.
Horizon HSD will serve as an advanced solution for Chery’s “Falcon,” globally debuting alongside the Journey 6P computing solution under the Xingtu brand, with mass production officially starting in September 2025. To date, Horizon has achieved pre-installed mass production shipments exceeding 8 million units, with over 200 models launched and more than 310 models designated for mass production, accompanying over 5 million car owners for safe and pleasant travel.
Behind these impressive figures, Arm technology has provided strong support. From the Journey 2 to the Journey 6 series of driving assistance computing solutions, Horizon has maintained close technical cooperation with Arm, empowering multiple models from manufacturers including SAIC, Chery, BYD, GAC, Geely, Volkswagen, Li Auto, and NIO. Notably, the newly launched model of NIO’s new brand Firefly, equipped with Horizon’s Journey computing solution, has recently been officially launched, becoming a highlight of this Shanghai Auto Show. The close collaboration between Arm and its partners not only accelerates the rapid evolution of driving assistance technology but also witnesses the prosperity of the automotive industry.
Arm Technology Continues to Evolve, Building the Computing Power Foundation for Future Automobiles
In the automotive field, Arm has focused its investment for over twenty years, continuously promoting technological evolution, with its technology leading the development of industry applications. Today, the Arm AE IP, which combines excellent performance, scalability, energy efficiency, and unique safety features, has become the cornerstone of automotive electronic products, continuously empowering leading automotive OEMs both domestically and internationally. In the AI era, to meet the market’s demand for high automotive computing power and performance levels, Arm has introduced server-class Neoverse CPUs into the Arm AE IP product line, creating a new automotive-specific CPU—Arm Neoverse V3AE—designed specifically for high-end ADAS and intelligent driving use cases that require ultra-high single-thread performance. This is also the first time Arm has brought the Armv9 architecture into automotive applications, allowing the industry to benefit from the advantages of AI, safety, and virtualization features brought by the new generation of Arm architecture.
This year, Arm will also launch the Automotive Computing Subsystem (CSS), providing pre-integrated and validated AE IP configurations for the partner ecosystem, further optimizing performance, power consumption, and chip area.
With expertise in energy efficiency, performance, and functional safety, continuous technological evolution closely aligned with industry development trends, and close cooperation with ecosystem partners, Arm’s market share in the automotive field continues to grow. Currently, 94% of global automotive manufacturers have adopted Arm technology in their latest models. Specifically, in segmented 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, IoT capabilities, and AI. Arm will continue to work with a broad automotive ecosystem to provide scalable, efficient, and secure solutions, jointly unleashing the potential of the AI era.
