The automotive electrical distribution systems market is witnessing transformation driven by rapid vehicle electrification and integration of complex electronic architectures. Modern vehicles, particularly electric and hybrid models, require robust distribution networks to manage power supply across various systems such as propulsion, infotainment, and battery management. The increase in the number of electronic control units (ECUs) per vehicle has led to more intricate wiring harnesses, placing greater emphasis on efficiency, lightweight materials, and compact designs. As automakers continue to innovate, the need for electrical systems that can support advanced features while optimizing space and weight becomes more pronounced.

Market Drivers

Rising Electrification of Vehicles

As the global automotive industry accelerates the shift toward electric mobility, the demand for sophisticated electrical distribution systems is increasing. Electric vehicles (EVs) rely on intricate networks of wires, connectors, and harnesses to deliver power from battery packs to propulsion motors, onboard chargers, inverters, and auxiliary components.

According to the International Energy Agency (IEA), 2023, the increasing electrification of vehicles, including EVs, hybrids, and ADAS-enabled vehicles, has significantly increased the complexity and length of electrical wiring harnesses.
Electric vehicles require up to 30-40% more wiring and connectors than internal combustion engine (ICE) vehicles, especially in high-voltage systems.
Modern electric cars contain up to 5 km of wiring, compared to 1.5-2 km in conventional ICE models.

This transformation is not limited to battery-electric vehicles (BEVs) but extends to hybrid and plug-in hybrid models as well. Modern EV platforms are architected around high-voltage systems that necessitate enhanced insulation, heat resistance, and robust current-carrying capacity. Electrical distribution systems are evolving to accommodate bidirectional power flows, support fast charging infrastructure, and ensure minimal energy loss. As automakers invest in expanding their EV lineups and governments reinforce zero-emission targets, the need for tailored electrical architecture is becoming a design priority. From modular high-voltage harnesses to flexible flat cables that reduce bulk, innovations are addressing energy efficiency, system weight, and space constraints. The electrification trend is fundamentally changing how vehicles are powered and controlled, and electrical distribution networks are at the heart of this transition, supporting everything from propulsion to battery thermal management and power electronics integration.

Key Market Challenges

Complexity in Electrical Architecture Design

As modern vehicles integrate more electronic features, the design and layout of electrical distribution systems become increasingly complex. Managing the interconnection of hundreds of components, sensors, and control modules within limited vehicle space poses significant design challenges. Engineers must consider factors such as electromagnetic compatibility, signal latency, and thermal effects while minimizing wire length and weight. This complexity increases with the adoption of zonal or centralized architectures, where high-speed data and power must be routed through fewer but more critical pathways. Ensuring reliable signal and power transmission under all operational conditions requires intricate planning and advanced simulation tools. Any design flaw can lead to functional failures, diagnostic errors, or reduced system efficiency. The growing vehicle diversity-from compact EVs to autonomous trucks-further compounds the challenge, as each platform may require a unique wiring topology. This intricate balancing of performance, weight, safety, and cost is one of the primary hurdles manufacturers face in developing next-generation electrical distribution systems.

Key Market Trends

Shift Toward Centralized Electrical Architectures

Automakers are transitioning from traditional distributed architectures to more centralized electrical systems.

For instance, in June 2025, NXP Semiconductors and Rimac Technology partnered to co-develop a centralized vehicle computing architecture that enables advanced domain and zonal control for next-generation electric and intelligent vehicles. The system will leverage NXP's processors and safety chips to manage complex functions such as ADAS, connectivity, and battery management. This collaboration aims to simplify vehicle electrical/electronic architectures, reduce wiring complexity, and enhance software-defined vehicle capabilities. The solution is designed to support high-performance, secure, and scalable vehicle platforms suited for future mobility applications.

In a centralized layout, key functions such as power distribution, data processing, and diagnostics are managed through fewer, more powerful control units rather than multiple decentralized modules. This consolidation reduces wiring complexity, lowers weight, and enhances system scalability. As vehicles become more software-defined and reliant on electronic control units (ECUs), centralized architectures offer a platform for better data handling, over-the-air updates, and streamlined communication protocols. The growing integration of advanced driver assistance systems (ADAS), connectivity features, and electrified powertrains further supports the trend, as centralized systems simplify integration and improve overall vehicle efficiency. This evolution reflects the need to support increasingly sophisticated digital and electronic functionalities in modern vehicles.
