Automotive 48V System Market Report 2026

The automotive 48v system market size has grown exponentially in recent years. It will grow from $8.84 billion in 2025 to $11 billion in 2026 at a compound annual growth rate (CAGR) of 24.4%. The growth in the historic period can be attributed to stricter emission norms, downsizing of engines, adoption of start-stop systems, fuel efficiency regulations, mild hybrid penetration.

The automotive 48v system market size is expected to see exponential growth in the next few years. It will grow to $26.74 billion in 2030 at a compound annual growth rate (CAGR) of 24.9%. The growth in the forecast period can be attributed to electrification mandates, cost reduction in power electronics, 48v adoption in mass vehicles, advanced energy management, modular vehicle platforms. Major trends in the forecast period include adoption of mild hybrid architectures, integration of advanced power electronics, demand for higher electrical efficiency, expansion in premium vehicle segments, platform standardization.

The rising demand for electric and hybrid vehicles is expected to drive the growth of the automotive 48V system market in the coming years. Electric vehicles are automobiles powered by an electric motor that draws energy from a battery and can recharge from external power sources. Automotive 48V systems enable more efficient power distribution, optimizing engine accessories and vehicle electronics while supporting EV components without compromising fuel-saving measures. For instance, in August 2024, according to the US Energy Information Administration, a US-based government agency, in the second quarter of 2024 (2Q24), combined sales of hybrid vehicles, plug-in hybrid electric vehicles (PHEVs), and battery electric vehicles (BEVs) accounted for 18.7% of total new light-duty vehicle (LDV) sales, up from 17.8% in 1Q24. This growth was mainly driven by hybrid electric vehicles (HEVs), whose share increased from 8.6% in 1Q24 to 9.6% in 2Q24, while PHEV share rose slightly from 1.7% to 2%, and BEVs reached 7.1% of the LDV market, roughly in line with their 2Q23 share. Therefore, the increasing adoption of electric and hybrid vehicles is fueling the automotive 48V system market.

Product innovation stands out as a dominant trend, with major companies actively pursuing the development of innovative solutions to solidify their market positions. In February 2023, Peugeot, a renowned French automobile brand under Stellantis, introduced a new 48V hybrid powertrain for the 3008 and 5008 models. This innovative hybrid system integrates a 136hp PureTech petrol engine with a 6-speed dual-clutch electrified gearbox, featuring an integrated electric motor. This configuration contributes to a remarkable 15% reduction in fuel consumption. Notably, the hybrid system empowers the vehicle to operate in 100% electric mode during low-speed maneuvers in congested areas, showcasing the versatility and fuel-efficiency of the 48V hybrid powertrain.

In October 2023, Infineon Technologies AG, a renowned semiconductor manufacturer based in Germany, completed the acquisition of GaN Systems Inc. for $830 million. This strategic move signifies a significant acceleration of Infineon's GaN technology development, establishing its dominance as a primary force in the GaN arena. This acquisition allows Infineon to leverage GaN Systems Inc.'s extensive portfolio of power conversion technologies and advanced application expertise, reinforcing its standing as a premier leader in power semiconductors. Furthermore, this acquisition promises to substantially expedite product development, reducing time-to-market for innovative solutions. GaN Systems Inc., based in Canada, specializes in the production of automotive 48V systems.
