Advances in electric and hybrid vehicle technologies are influencing the evolving demand for starter motors and alternators, which are crucial in traditional internal combustion engines but may see less demand in electric vehicles moving forward.

Sales Channel Analysis

OEM Dominates with 84.3% Share in Automotive Alternator & Starter Motor Market in 2024

In 2024, OEM (Original Equipment Manufacturer) dominated the Automotive Alternator & Starter Motor Market in the By Sales Channel Analysis segment, holding a substantial 84.3% share.

This dominance can be attributed to the strong demand from vehicle manufacturers who require high-quality, durable alternators and starter motors for new vehicle production. OEMs supply these components directly to automotive manufacturers, ensuring compatibility and performance with the latest models, thus meeting the stringent requirements of vehicle manufacturers globally.

The Aftermarket segment, while considerably smaller in comparison, continues to see steady growth, driven by the need for replacement and repair parts. As vehicles age, the demand for aftermarket alternators and starter motors increases, especially in regions where vehicle maintenance is a significant part of the automotive ecosystem. The aftermarket sector benefits from a growing number of independent repair shops, online retailers, and the increasing trend of vehicle ownership longevity.

Despite the steady growth of the aftermarket, OEM’s dominant position remains intact, as new vehicle production and strict industry standards require high-performance components that OEMs are best positioned to supply.

However, the aftermarket continues to be a vital source of revenue, particularly for aging vehicle fleets and in regions with a high number of vehicles in operation.

Drivers

Growth in Automotive Production Drives Demand for Starter Motors

The automotive alternator and starter motor market is significantly influenced by the rising global production of vehicles. As more cars are manufactured worldwide, the demand for starter motors increases, as they are essential components in nearly every internal combustion engine vehicle.

This surge in vehicle production is primarily driven by factors like higher consumer demand, technological advancements, and enhanced production capabilities of automotive manufacturers.

Additionally, emerging economies, particularly in regions like Asia-Pacific, are experiencing rapid urbanization and an improvement in living standards, which further boosts vehicle sales. As more consumers purchase vehicles, the need for starter motors continues to grow. Another key factor contributing to the market’s expansion is the rise of electric vehicles (EVs), including hybrid and fully electric models.

These vehicles require specialized starter motors, creating new growth opportunities. Furthermore, the growing focus on fuel efficiency in the automotive sector has led to innovations in starter motor technology, pushing manufacturers to develop high-performance motors that reduce energy consumption and improve overall vehicle efficiency. As automakers strive to meet these demands, the automotive alternator and starter motor market is poised for continued growth.

Restraints

Substitute Technologies Limit Demand for Traditional Starter Motors

One of the key restraints in the automotive alternator and starter motor market is the rise of alternative starting systems, particularly in hybrid and electric vehicles. These vehicles often use different technologies, such as power electronics or high-voltage battery systems, which can reduce or eliminate the need for traditional internal combustion engine (ICE) starter motors.

As more consumers and manufacturers shift toward electric vehicles (EVs), the demand for conventional starter motors decreases, especially in markets focused on clean energy solutions.

Additionally, developments in other automotive power sources, like supercapacitors, are also emerging as potential alternatives. Supercapacitors, for example, store and discharge energy more quickly than traditional batteries, offering an energy-efficient solution for starting engines without relying on a starter motor.

This could put pressure on the demand for traditional starter motors, especially if these alternatives become more widely adopted. As these technologies improve, there is a growing risk that they may replace conventional starter motors in some vehicle segments, slowing down the growth of the traditional starter motor market.

Consequently, automakers are facing a dilemma of balancing the demand for traditional components while integrating newer, more advanced technologies, creating uncertainty for the future of the starter motor market.
