Automotive chip suppliers refer to companies that supply various integrated circuits (ICs) and semiconductor components to vehicle manufacturers. Automotive microchips serve as the core hardware of vehicle electronic architectures, functioning as the "brain" and "central nervous system" of modern smart vehicles. As cars transition from purely mechanical machines into "smart terminals on wheels", the application of microchips has expanded beyond powertrain management and chassis control into smart cockpits, advanced driver assistance systems (ADAS), and centralised vehicle computing platforms. A conventional internal combustion engine (ICE) vehicle typically requires roughly 600 to 700 chips, an electric vehicle (EV) demands around 1,600, while a software-defined smart vehicle sees this figure surge to 3,000 units.
Automotive chips are broadly categorised by function into computing and control (MCU/SoC), power semiconductors, sensors, as well as communication and memory. Each segment features distinct supplier dynamics and varying degrees of domestic localisation:
In the MCU (Microcontroller Unit) segment, the global high-end market has long been dominated by international giants such as NXP, Infineon, and Renesas, with automotive-grade MCUs presenting formidable technical entry barriers due to intricate manufacturing processes. In China, BYD Semiconductor introduced a 32-bit M4F core MCU in 2025, while ChipON's KungFu core MCU cumulative shipments crossed the 100-million-unit threshold early that year, reflecting an aggressive push for domestic substitution. By 2025, China's localisation rate for automotive-grade MCUs climbed to approximately 18%.
Smart cockpit SoCs (System on Chip) continue to see global players lead while Chinese chipmakers narrow the gap. In 2025, standard factory-fitted smart cockpit penetration in China's passenger car market (excluding imports and exports) reached 76.62%. In the cockpit domain controller segment, Qualcomm maintained the top spot with a commanding 74.9% installation share, backed by its mature technological prowess and software ecosystem. Meanwhile, domestic contenders SemiDrive and Huawei HiSilicon took fifth and sixth spots with 3.77% and 3.39% market shares respectively, signifying that homegrown silicon is evolving from merely viable alternatives into truly competitive solutions.
The power semiconductor sector has witnessed remarkable progress in local substitution. Between January and June 2025, BYD Semiconductor recorded 1.7425 million sets of power device installations, securing the top spot in China with a 27.8% market share and overtaking Infineon as the market leader. StarPower Semiconductor and Silan Microelectronics also maintained substantial market presence. In 2025, Silan Microelectronics saw rapid expansion in its automotive electronics division, with revenue from automotive and photovoltaic IGBT and SiC products reaching RMB 3.273 billion, representing a year-on-year surge of approximately 43%.
The global automotive semiconductor market is projected to expand from USD 68 billion in 2024 to USD 132 billion by 2030, charting a compound annual growth rate (CAGR) of 10%. The top five global manufacturers control roughly half the total market, with Infineon leading the pack after posting over USD 8 billion in automotive revenue in 2024. While US chipmakers continue to dominate advanced computing, analogue circuits, and memory, Chinese suppliers—backed by robust national policy support—are making swift headway in cockpits, ADAS, and silicon carbide (SiC) power electronics.
In the automated driving chip arena, Horizon Robotics has surpassed 8 million units in cumulative Journey series shipments across more than 310 design-win vehicle models, while Black Sesame Technologies' Huashan A1000 SoC delivers robust processing for Level 2+ driving assistance. In the 2025 core competitiveness rankings for Chinese automotive chipmakers, BYD Semiconductor, Horizon Robotics, StarPower Semiconductor, SiEngine, and Black Sesame Technologies led the field. SiEngine's automotive-grade chip installations have exceeded 1 million vehicles, with its 5nm DragonHawk II processor now in mass production and delivery, enabling integrated cockpit-driving compute and City NOA capabilities.
With compute power superseding horsepower as the defining metric of vehicle capability, proprietary in-house chip development has become an industry-wide imperative for carmakers globally. Tesla led the charge in vertical integration; BYD's semiconductor arm covers an extensive portfolio spanning MCUs, SiC, and IGBTs; while emerging EV makers like XPENG, NIO, and Li Auto have rolled out proprietary smart driving chips including Turing, Shenji, and M100 respectively. This shift is accelerating the overhaul of conventional Tier-1 supply chains and fundamentally reshaping the value distribution across the automotive ecosystem.
In the first half of 2026, the domestic localisation rate of automotive-grade chips in China surpassed 35%, marking a strategic transition from piecemeal component replacement to comprehensive system-level deployment. Geographically, China's automotive chip sector displays strong regional clustering, with five key industrial hubs—Guangdong, Jiangsu, Zhejiang, Shanghai, and Shandong—accounting for over 55% of the industry, anchoring the core framework of the domestic automotive semiconductor supply base.
