The automotive hybrid starter generator market size is expected to see strong growth in the next few years. It will grow to $23.46 billion in 2030 at a compound annual growth rate (CAGR) of 5.1%. The growth in the forecast period can be attributed to vehicle electrification expansion, stricter emission norms, demand for cost-effective hybrids, advancements in power electronics, growth of mild hybrid platforms. Major trends in the forecast period include shift toward 48-volt systems, rising adoption of mild hybrid vehicles, integration of regenerative braking, demand for compact starter generators, growth of fuel efficiency solutions.

Growing automotive industries are expected to propel the growth of the automotive hybrid starter generator market going forward. The automotive industry refers to the segment of the economy involved in the design, development, manufacturing, marketing, and sale of motor vehicles. The expansion of automotive industries is driven by shifting consumer preferences, economic conditions, supportive regulations and policies, globalization and trade, and advancements in manufacturing innovation. Hybrid starter generators are essential in the automotive sector as they improve fuel efficiency, lower emissions, and support smooth start-stop operations and regenerative braking in hybrid vehicles. For instance, in February 2024, according to the Society of Motor Manufacturers and Traders, a UK-based trade association, British car production in January rose by 21% to 82,997 units, with export volumes increasing by 11.6%, production for the domestic market surging by 64.5%, and electrified vehicle output rising by 4.5% to 29,590 units. Therefore, the expansion of the automotive industry is driving the growth of the automotive hybrid starter generator market.

The increasing adoption of electric vehicles is expected to propel the growth of the automotive hybrid starter generator market going forward. Electric vehicles (EVs) are automobiles that operate fully or partially on electric motors powered by batteries or other electrical energy sources, rather than relying entirely on internal combustion engines. The rising uptake of electric vehicles is largely fueled by growing environmental awareness, as consumers and governments aim to reduce greenhouse gas emissions and address climate change concerns. Automotive hybrid starter generators enhance electric vehicles by integrating efficient engine start-stop systems with regenerative energy recovery, thereby improving overall efficiency, reducing emissions, and extending battery lifespan. For instance, in January 2025, according to Cox Automotive, a US-based system software company, electric vehicle sales in 2023 were revised upward to 1,212,758 units, reflecting a 49% increase over 2022, and continued to rise in 2024, growing by 7.3% to reach 1,301,411 units. Therefore, the growing adoption of electric vehicles is driving the growth of the automotive hybrid starter generator market.
