Automotive Communication Technology Market Poised for Strong Expansion Through 2035

The automotive communication technology market is entering a transformative growth phase, fueled by the rapid evolution of connected, autonomous, and software-defined vehicles. Valued at USD 27.4 billion in 2025, the market is projected to surge to USD 110.8 billion by 2035, expanding at a robust CAGR of 15.0% over the forecast period.

This growth reflects a fundamental shift in vehicle architecture, where high-speed, secure, and reliable in-vehicle communication networks have become mission-critical. Between 2020 and 2024, the market expanded from USD 13.6 billion to USD 23.8 billion, driven by early adoption of established protocols such as Controller Area Network (CAN), Local Interconnect Network (LIN), and FlexRay. As vehicles integrate more electronic control units (ECUs), sensors, and software intelligence, communication technologies are emerging as a core enabler of next-generation mobility.

Growth Accelerates with ADAS, V2X, and Software-Defined Vehicles

From 2025 to 2030, the market is expected to nearly double, reaching USD 55.1 billion, accounting for almost half of total projected growth. This phase is shaped by:

• Rapid deployment of advanced driver-assistance systems (ADAS)
• Scaling adoption of vehicle-to-everything (V2X) communication
• Growing reliance on software-defined vehicle architectures
• Increasing bandwidth requirements supported by automotive Ethernet

Between 2031 and 2035, the market accelerates further from USD 63.3 billion to USD 110.8 billion, driven by mass adoption of autonomous driving features, electric vehicle proliferation, and standardization of high-speed in-vehicle networks.

CAN Maintains Leadership Despite Emerging Protocols

The Controller Area Network (CAN) segment continues to dominate, accounting for 36.4% of market share in 2025. Its reliability, cost efficiency, and deterministic performance make it indispensable for safety-critical functions such as braking, powertrain control, and airbag deployment. While Ethernet and FlexRay gain traction in high-bandwidth applications, CAN remains foundational across economy and mid-segment vehicles.

OEMs Drive Market Integration

OEMs lead distribution with a 69.3% share, highlighting the shift toward factory-integrated communication architectures. Automakers are embedding advanced communication technologies at the design stage to meet regulatory requirements, enable over-the-air updates, and support future autonomous capabilities.

Asia-Pacific Emerges as the Fastest-Growing Region

Asia-Pacific is the primary growth engine, led by:

• China (20.3% CAGR) – supported by 5G rollout, smart transportation projects, and connected fleet adoption
• India (18.8% CAGR) – driven by vehicle safety mandates, telematics expansion, and smart city initiatives

Europe remains compliance-driven, while North America represents a mature yet steadily expanding market for connected vehicle technologies.

Market Outlook

As vehicles become increasingly connected, autonomous, and data-driven, automotive communication technology is evolving from a supporting function to a strategic backbone of vehicle intelligence. Continued innovation in V2X protocols, automotive Ethernet, cybersecurity, and edge computing will further strengthen its role across passenger and commercial vehicles. By 2035, the market will stand as a critical pillar of the global connected mobility ecosystem.
