The wiring harness segment dominated and captured almost 24% of the market share, as it is the framework of an entire vehicle’s electrical system and integrates all electrical and electronic systems. This is particularly true for newer vehicles, including EVs and high-end models, which require complex wiring systems to accommodate safety, infotainment, and connectivity requirements. Moreover, equipment manufacturers are pursuing lightweight wiring harnesses that offer heat-resistant solutions to enhance energy efficiency and vehicle performance.
The control modules segment is expected to grow at the fastest rate in the forecasted period due to the increasing vehicle automation and electrification. Control modules manage all major systems, including engine control, transmission, battery management, and ADAS (advanced driver assistance systems). Demand in accordance with the trend to increase fuel efficiency while embracing increased safety via electronic control systems is rising for advanced control modules, increasingly in use as newer vehicles are becoming software-driven with greater reliance on electronic control systems.
The passenger vehicle segment dominated and captured almost 54% of the automotive electrical systems market share due to its high global production and adoption levels. There is strong consumer demand across the globe for comfort, safety, and smart technologies, which has resulted in an increase in the integration of advanced electrical systems into the automobile.
The EVs & hybrids segment is expected to grow at the fastest rate in the forecasted period, as both governments and consumers move towards cleaner mobility solutions. EVs and hybrids also rely heavily on electrical systems for propulsion, power distribution, and energy management. Considerable global investments towards EV infrastructure, diminishing battery costs for EVs, and heavy incentives for zero-emission vehicles continues to increase adoption.
The powertrain systems segment dominated and captured around 35% of the automotive electrical systems market share due to their importance in vehicle operation, managing energy conversion, and distribution. Powertrains have electrical systems that oversee ignition, fuel injection, transmissions, and hybrid drive systems. Because of the increasing focus on improving efficiency and reducing emissions, car manufacturers will continue to enhance powertrain electronics.
The ADAS segment is expected to be the fastest growing segment in the forecasted period. The ADAS segment is increasing fastest due to a heightened emphasis on safety regulations and consumer wants for advanced driving features worldwide. Advanced Driver Assistance Systems makes use of sensors, cameras, radar, and control units to assist in speeding, braking, staying in lanes, and avoiding collisions.
The automotive electrical systems market is changing with the introduction of new technologies such as advanced sensors, smart batteries, and advanced electronic control units. Electric and hybrid vehicles require high-voltage systems to operate with the efficient wiring required by these vehicles. Connected and autonomous driving vehicles will incorporate software, cameras, and communication to connect with other vehicles. These changes improve vehicle safety, intelligence, and energy efficiency, thereby expanding the automotive market.
Asia-Pacific dominated and captured around 40% of the total automotive electrical systems market share due to its strong vehicle production and increased demand for electric and hybrid vehicles. The growth of the region was fueled by urbanization, government incentives for electric vehicles, and cost-effective manufacturing. Local suppliers and automakers are implementing intelligent, energy-efficient systems to meet the demand for safety and performance.
China led the Asia-Pacific market due to its significant production volume of vehicles and significant push for electric mobility, due to government incentives for electric vehicles, battery innovation, and local manufacturing of electric vehicles. Local suppliers were rapidly adopting electrical systems in vehicles due to the Consumer EV subsidies provided by the government. Moreover, major Chinese automakers are developing advanced control units and Smart electrical components to reach their new energy targets.
Europe experienced rapid growth in the automotive electrical systems market, leading global growth, driven by strict emission regulations and a quick transition to electric and hybrid vehicles. Governments were supporting cleaner transportation with strong government-funded EV adoption programs and robust charging infrastructure. Automotive companies were supporting premium electrical systems, advanced driver assistance systems (ADAS), and smart connectivity technologies.
Germany dominated the European market due to its traditional strong automotive industry and bias towards innovation. Germany's automotive manufacturing organizations were major investments in the deployment of electric power trains and control modules, as well as advanced electronics. There was also significant government support for green mobility and financial support for R&D aimed at efficiency improvements. Germany became a center for the testing and evaluation of smart electrical systems and ADAS technologies that supported Germany's leadership and position in the rapidly growing automotive electrical systems market in Europe.
