The global automotive Ethernet market was valued at USD 2,516.4 million in 2023 and is projected to grow to USD 7,043.7 million by 2030, expanding at a compound annual growth rate (CAGR) of 15.9% from 2024 to 2030. Automotive Ethernet serves as a communication backbone within vehicles, offering high-speed and reliable data transmission between electronic systems and components.

Market expansion is primarily driven by the widespread adoption of Ethernet technology in vehicles, owing to its advantages such as high bandwidth, scalability, cost-effectiveness, IP system integration, reliability, and support for time-sensitive networking (TSN). The increasing integration of connected car technologies and the rising consumer demand for sophisticated in-vehicle infotainment systems are also key contributors to the market’s growth.

The growing need for faster data transmission within vehicles is leading to the adoption of advanced Ethernet standards such as 10BASE-T1S and 100BASE-T1. These standards support speeds up to 1 Gbps and 10 Gbps, essential for processing the high data loads from HD cameras, infotainment platforms, and other bandwidth-intensive vehicle systems. This transition is enabling the development of more responsive and capable in-vehicle networks, supporting the demand for increasingly connected and data-driven automotive technologies.

A major trend shaping the market is the industry's transition toward software-defined vehicles (SDVs)—vehicles where functionality and features are predominantly managed through software. Automotive Ethernet plays a crucial role in this shift, delivering the high-speed and reliable communication required for real-time software updates and system enhancements. With its bandwidth capabilities, Ethernet supports scalable and flexible vehicle architecture, enabling over-the-air updates and integration of advanced functionalities like autonomous driving systems and enhanced infotainment.
