An automotive hybrid starter generator (HSG) is a component used in hybrid and mild hybrid vehicles to improve engine start/stop functionality and enhance overall vehicle efficiency. It plays a crucial role in modern hybrid vehicles by combining starter and generator functions, supporting start-stop systems, enabling regenerative braking, and boosting vehicle efficiency and performance.
The main types of automotive hybrid starter generators include 12-volt, 48-volt, and other configurations. A 12-volt hybrid starter generator is a compact system that integrates the roles of both starter and generator to enhance fuel efficiency and reduce emissions in hybrid vehicles. It comprises components such as an electric motor or generator, a power electronic controller, and a battery, and it can offer varying power levels, low (up to 15 kW), medium (15-30 kW), and high (above 30 kW). These systems are used in passenger cars, light commercial vehicles, and heavy commercial vehicles.

The growth in the historic period can be attributed to urbanization and traffic congestion, growing consumer awareness, increasing demand for more fuel-efficient vehicles, rising awareness of air quality issues, increasing infrastructure for hybrid and electric vehicles.
The automotive hybrid starter generator market size is expected to see strong growth in the next few years. It will grow to $23.06 billion in 2029 at a compound annual growth rate (CAGR) of 5.6%. The growth in the forecast period can be attributed to rising disposable income, increasing market penetration of hybrid vehicles, expansion of aftermarket services for hybrid vehicles, rising awareness about environmental impact, growing trend towards electrification in the automotive industry. Major trends in the forecast period include demand for research and development, innovation in hybrid technologies, public and private sector partnerships, customization and flexibility, advancements in lightweight vehicle materials.
The expansion of the automotive industry is expected to drive the growth of the automotive hybrid starter generator market. The automotive industry encompasses the design, development, manufacturing, marketing, and sale of motor vehicles. This sector is growing due to evolving consumer preferences, economic factors, regulatory and policy support, globalization and trade, and innovations in manufacturing. Hybrid starter generators are crucial for enhancing fuel efficiency, reducing emissions, and enabling seamless start-stop and regenerative braking functions in hybrid vehicles. For example, in February 2024, the Society of Motor Manufacturers and Traders, a UK-based trade association, reported a 21.0% increase in British car manufacturing output in January, reaching 82,997 units. Export volumes rose by 11.6%, domestic production soared 64.5%, and production of electrified vehicles grew 4.5% to 29,590 units. This growth in the automotive industry is fueling the demand for hybrid starter generators.
Leading companies in the automotive hybrid starter generator market are advancing technologies such as integrated belt-driven starter generators to improve efficiency, reduce emissions, and enhance vehicle performance. An integrated belt-driven starter generator (BSG) combines the functions of a starter motor and a generator into one unit for hybrid and mild hybrid vehicle systems. For example, in March 2022, Nexteer Automotive, a US-based company specializing in automotive components, introduced the 48-volt Integrated Belt-Driven Starter Generator (iBSG). This component is designed to improve vehicle efficiency and performance, particularly in mild hybrid systems, by replacing traditional alternators. It functions as a reversible starter generator that captures kinetic energy during deceleration and reuses it during acceleration.
In October 2024, Schaeffler Technologies AG & Co. KG, a Germany-based company specializing in the development, manufacturing, and sale of high-precision components and systems for the automotive industry, acquired Vitesco Technologies Group AG for an undisclosed amount. Through this acquisition, Schaeffler Technologies aims to strengthen its sustainable mobility capabilities, create significant synergies, and reinforce its position as a leader in electrification technologies within the automotive sector.
