Market Dynamics

Drivers

• The IEA expects electric-car sales to exceed 20 million in 2025, representing more than one-quarter of global car sales, expanding CAN-FD, LIN, gateway, and security requirements around battery-management, thermal-control, charging, and update functions.
• UNECE Regulation No. 156 establishes requirements for software-update management systems and safe software updates, requiring authenticated vehicle connectivity, traceability across affected ECUs, and a network able to distribute software without disrupting safety functions.
• Bosch identifies zonal and centralized E/E architectures, hardware-software separation, and OTA infrastructure as linked foundations for software-defined vehicles.
• ADAS raises the data-rate and latency requirements of communication networks because cameras, radar, and other sensors must be fused before control decisions are returned to braking, steering, or powertrain systems.
• UNECE Regulation No. 155 requires a cybersecurity management system covering the vehicle lifecycle, while ISO/SAE 21434 provides a cybersecurity-engineering framework for road vehicles.
• NXP's S32J Ethernet-switch family combines time-sensitive networking, MACsec security, and ASIL-D-oriented safety features, illustrating how network hardware is being specified as a safety and security control point rather than a passive transport layer.
• HARMAN introduced its Ready Connect 5G telematics control unit in February 2024 using Qualcomm's Snapdragon Auto 5G Modem-RF Gen 2, with modular provision for 4G-to-5G upgrades.
• HARMAN and Qualcomm subsequently announced satellite-communication integration for the Ready Connect platform in January 2025, extending connectivity beyond areas with terrestrial cellular coverage.
• The FCC's C-V2X order made C-V2X the permitted technology for Intelligent Transportation System operations in the 5.895–5.925 GHz band and set a December 14, 2026 sunset for DSRC roadside operations.
• SAE J2735 defines V2X message sets, while SAE J3161/1 specifies onboard requirements for LTE-V2X V2V safety communications, reducing the risk that chipset, roadside-equipment, and TCU investments will be stranded.
• Qualcomm's Snapdragon Ride Flex platform was selected for BMW's Neue Klasse architecture, linking digital-cockpit and ADAS workloads on a common automotive compute platform.
• Renesas introduced the R-Car X5H as a 3nm automotive SoC for ADAS, infotainment, and gateway applications, demonstrating how vehicle programs are consolidating formerly separate domains into fewer computing nodes.

Restraints

• Continental's zone control units, which entered series production in April 2024 for European and Asian vehicle manufacturers, integrate Ethernet, CAN/FD, and LIN interfaces in a scalable architecture and show that zonal control still requires legacy protocols to coexist with Ethernet.
• OEM-specific middleware, diagnostics, AUTOSAR configurations, and lifecycle update processes can lengthen design cycles even when protocol hardware is standardized.
• Connectivity expands the vehicle attack surface through telematics, Wi-Fi, Bluetooth, V2X, and diagnostic interfaces; R155 and ISO/SAE 21434 make cybersecurity a lifecycle obligation rather than a one-time feature.
• The impact is most restrictive in price-sensitive vehicles and aftermarket installations: economy vehicles cannot absorb unlimited gateway, modem, and security content, while retrofit products must establish trusted access to architectures that were not designed to provision them.
• Brevintel analysis finds the restraints are creating a qualification advantage for suppliers that can bridge distributed and zonal architectures with functional-safety and cybersecurity credentials.
• A gateway supplier that can demonstrate interoperability across CAN, LIN, Ethernet, and secure update workflows reduces program risk for an OEM, and that reduction in validation exposure can outweigh a lower-priced component offer.
• Smaller suppliers may retain opportunities in discrete silicon or specialized tools, but broader platform awards increasingly depend on certification evidence and interoperability capability.
• The aftermarket remains relevant for fleet tracking and diagnostics, but it is less able to capture the highest-value factory-integrated gateway and ADAS networking content.

Segmentation Analysis

Component

• Hardware is the largest component category, valued at USD 14,206.3 million in 2025 and projected to reach USD 41,882.4 million by 2035 at an approximately 11.9% CAGR.
• Transceivers, connectors, cables, gateways, and domain controllers remain indispensable even as vehicle architectures consolidate, because centralized computing increases the performance requirement of each remaining network node.
• Gateways and domain controllers carry disproportionate strategic importance within hardware because they aggregate protocols, apply routing and security policies, and link zonal nodes to central compute.
• Software, valued at USD 5,188.1 million in 2025 and projected to reach USD 17,583.4 million by 2035, expands at an approximately 13.5% CAGR through 2035.
• Services grow from USD 2,280.0 million to USD 7,289.7 million as OTA management, fleet connectivity, and cybersecurity monitoring become recurring lifecycle activities.
• Brevintel analysis finds segment performance is shaped by two parallel upgrade cycles: a hardware cycle in protocol migration and a software-and-services cycle driven by cybersecurity management, OTA compliance, diagnostics, and monetizable connected features.
• Suppliers exposed to both cycles can capture value at vehicle launch and after sale.
• The strategic opportunity lies in designing scalable platforms that preserve low-cost LIN and CAN nodes while adding higher-value Ethernet, gateway, and software functions only where the vehicle program can support them.

Bus module

• CAN is the largest bus-module segment, increasing from USD 9,078.5 million in 2025 to USD 29,966.6 million by 2035 at an approximately 13.2% CAGR.
• Bosch demonstrated a CAN SIC XL transceiver supporting ISO 11898-1:2024 CAN-XL operation at up to 20 Mbit/s in November 2024, so CAN serves as an architectural bridge rather than a protocol displaced immediately by Ethernet.
• LIN grows from USD 5,318.8 million to USD 17,196.2 million at an approximately 13.0% CAGR because low-cost peripheral functions remain numerous even in zonal vehicles.
• Zonal architectures consolidate these leaf nodes through an Ethernet uplink but do not eliminate the economic advantage of LIN for seats, lighting, mirrors, and other body functions.
• Ethernet rises from USD 3,709.0 million to USD 10,847.8 million at an approximately 11.8% CAGR and becomes the critical backbone for sensor fusion, centralized compute, and software distribution.
• FlexRay grows more slowly, from USD 2,199.3 million to USD 5,073.4 million, as TSN Ethernet gains deterministic capability.
• MOST advances from USD 1,368.7 million to USD 3,671.6 million largely through residual infotainment and installed-base demand.
• CAN's installed tool base, safety history, and adaptability through CAN-FD and CAN-XL allow it to remain relevant in powertrain, chassis, battery, and body applications.

Connectivity

• In-vehicle communication remains the larger value pool because every vehicle requires internal networks and physical interconnects.
• The migration to zonal designs changes the topology: fewer distributed ECUs can mean more sophisticated Ethernet ports, gateway functions, and scheduling software at each surviving control node.
• External communication includes C-V2X, DSRC, cellular telematics, Wi-Fi, and Bluetooth.
• The U.S. C-V2X regulatory decision provides a clearer demand signal for modem and roadside-equipment suppliers.
• External connectivity also enables OTA updates, remote diagnostics, and fleet services, but it requires cybersecurity controls that meet the technical and procedural expectations of R155 and R156.
• Consumer expectations formed by smartphone and streaming experiences have permanently altered the specification floor for persistent high-bandwidth internet access, cloud-synchronized navigation, application stores, and audio-video streaming that can sustain 4K throughput.
• Clearer standards reduce the risk that chipset, roadside-equipment, and TCU investments will be stranded by competing radio approaches.
• Brevintel analysis treats in-vehicle networks as the volume base and external radios as the compliance, update, and service layer.

Vehicle and vehicle class

• India's AIS-140 framework requires vehicle-location tracking and emergency-alert systems for specified commercial public-service vehicles, supporting sustained demand for GPS/NavIC-based telematics and real-time transmission systems.
• Economy vehicles generate USD 2,614.0 million in 2025 and grow at an approximately 9.7% CAGR to USD 6,308.4 million by 2035.
• Mid-range vehicles are projected to grow fastest by class, from USD 8,656.4 million to USD 29,352.4 million at an approximately 13.5% CAGR, because they combine large production volumes with the migration of ADAS, digital cockpit, and connected-service features from premium platforms.
• Luxury vehicles remain the largest class in 2025 at USD 10,404.0 million and are projected to reach USD 31,094.7 million.
• Qualcomm's Snapdragon Ride Flex platform was selected for BMW's Neue Klasse architecture, demonstrating the convergence of cockpit and ADAS processing that increases dependence on high-performance in-vehicle networks.
• Cost sensitivity constrains the adoption of high-end gateways and sensor networks in economy vehicles, although basic telematics, safety functions, and body-control connectivity continue to expand.

Propulsion

• ICE vehicles remain the largest propulsion category, valued at USD 15,430.3 million in 2025 and projected to reach USD 44,953.2 million by 2035.
• Their continued importance reflects the scale of global vehicle production relative to EV sales.
• EVs are forecast to grow fastest, from USD 4,556.5 million to USD 16,468.6 million by 2035 at an approximately 14.2% CAGR, because battery management, charging, thermal control, and software updates add network content beyond conventional powertrain control.
• Hybrids increase from USD 1,687.5 million to USD 5,333.8 million at an approximately 12.7% CAGR.
• Hybrid architecture combines ICE controls with battery and motor-management requirements, producing a broader protocol load than a conventional ICE platform.
• This creates a practical near-term opportunity for suppliers that can support mixed powertrain architectures without requiring an OEM to change its network stack for each propulsion variant.
• Electrified powertrains add battery-management, thermal-control, charging, and update requirements, while ADAS adds high-bandwidth sensor links and stricter timing constraints.
• Brevintel analysis finds the fastest growth is concentrated where additional communication content is unavoidable rather than discretionary, including EV battery and charging networks.

Application

• Safety & ADAS is projected to expand fastest, from USD 7,833.8 million in 2025 to USD 28,017.3 million by 2035 at an approximately 14.1% CAGR.
• Sensor fusion and secure control pathways raise the value of Ethernet PHYs, switches, gateways, and deterministic traffic management.
• Powertrain & chassis rises from USD 2,548.2 million to USD 8,210.9 million, retaining CAN, CAN-FD, and selected deterministic-network demand for braking, steering, and active-chassis functions.
• Infotainment & telematics is the largest application in 2025 at USD 6,467.5 million and reaches USD 17,176.2 million by 2035.
• Its lower 10.8% CAGR reflects the maturity of core head-unit and connectivity hardware, with incremental value shifting toward software and application ecosystems.
• HARMAN expanded the Volkswagen Group Application Store with CARIAD in July 2024, including availability across selected Volkswagen Group brands.
• Body control & comfort rises from USD 3,995.6 million to USD 11,555.4 million, supported by growing node counts for comfort and personalization features.
• The others category grows from USD 829.3 million to USD 1,795.7 million, at an approximately 8.3% CAGR.

Sales channel

• OEM sales dominate, rising from USD 17,555.3 million in 2025 to USD 55,987.9 million by 2035 at an approximately 12.8% CAGR.
• The channel's importance follows from platform-development timing: gateway, network, and sensor-interface decisions are made well before vehicle production and usually persist through an entire platform cycle.
• Suppliers that secure OEM qualification can participate in high-volume production and subsequent software-service work.
• The aftermarket increases from USD 4,119.1 million to USD 10,767.7 million at an approximately 10.6% CAGR.
• It remains important for tracking devices, diagnostic interfaces, and retrofit connectivity, particularly in regulated fleet applications.
• ARAI maintains lists of approved GPS and IRNSS vehicle-tracking systems under AIS-140, indicating a formalized compliance ecosystem for such equipment.
• However, aftermarket products generally cannot match the access, safety integration, or cybersecurity provisioning of factory-installed communication systems.
• Economy vehicles and the aftermarket remain constrained by cost and integration limits relative to factory-integrated ADAS and zonal networking content.
