The growth in the forecast period can be attributed to growing adoption of smart grid technologies, increasing integration of renewable energy, rising demand for energy efficiency, expansion of cross-border transmission projects, and increasing focus on grid reliability and stability. Major trends in the forecast period include technology advancements in high-voltage transmission, innovations in grid management software, developments in energy storage integration, research and developments in superconducting transmission, and advancements in high-voltage direct current and flexible alternating current transmission systems technologies.

The growing demand for electric and hybrid vehicles is expected to drive the expansion of the transmission system market in the coming years. Demand for electric and hybrid vehicles refers to the rising global sales and adoption of vehicles equipped with electric or hybrid powertrains, which require suitable transmission or e‑drive systems to transfer motor power to the wheels. This increase is driven by consumers and governments worldwide shifting toward cleaner mobility to reduce greenhouse gas emissions and meet regulatory and environmental targets. The transmission system market supports this demand by providing advanced gearboxes, e‑drive units, and hybrid transmission systems specifically designed for electric and hybrid vehicles. For example, in May 2025, the International Energy Agency (IEA), a France-based intergovernmental organization, reported that electric car sales surpassed 17 million globally in 2024, accounting for over 20 percent of total car sales, with an additional 3.5 million electric cars sold compared to 2023. Consequently, the rising demand for electric and hybrid vehicles is fueling growth in the transmission system market.

Major companies in the transmission systems market are focusing on advanced features, such as high efficiency and an excellent torque-to-weight ratio, to improve energy efficiency, reduce weight, and allow flexible deployment across various vehicle platforms. High efficiency and an excellent torque-to-weight ratio refers to a system that converts most of its input power into useful work while delivering strong rotational force relative to its mass, resulting in powerful yet lightweight performance. For example, in October 2024, Magna International Inc., a Canada-based mobility technology supplier, introduced its Dual Clutch Transmission Eco (DCT Eco) for a European OEM. The system features a compact, efficient design with an optimal torque-to-weight ratio and a modular architecture that enables the same gearbox base to be used for purely internal-combustion engine (ICE) vehicles or hybrid platforms with minimal modifications. This launch demonstrates the integration of modularity, efficiency, and hybrid readiness in transmission systems, offering scalable, versatile, and high-performance vehicle powertrains.

In July 2023, MiddleGround Capital LLC, a US-based private equity firm focused on industrial and specialty distribution businesses, acquired Xtrac Ltd. for an undisclosed amount. This acquisition allowed MiddleGround Capital to expand its portfolio of advanced manufacturing companies, enhancing its capabilities in producing and supplying high-performance transmission systems for motorsport and premium automotive markets. Xtrac Ltd., based in the UK, manufactures transmission systems for internal combustion, hybrid, and electric vehicles.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have significantly impacted the transmission systems market by increasing costs of imported transformers, conductors, switchgear, and high voltage equipment. large scale infrastructure projects in north america and europe are most affected due to global component sourcing. project timelines and capital costs have risen as a result. however, tariffs have stimulated domestic manufacturing, localization of transmission equipment production, and long term supply chain strengthening for critical grid assets.

The transmission systems market encompasses technologies and solutions that enable the efficient transfer of electrical power over long distances, ensuring reliable and stable energy delivery. Its main objective is to improve the performance, safety, and sustainability of electrical grids while minimizing transmission losses and operational inefficiencies. It also supports advanced capabilities such as smart grid integration, high-voltage component monitoring, and grid modernization for enhanced energy management.

The primary components of transmission systems include transformers, transmission lines and towers, switchgear and switchboards, insulators, and circuit breakers. Transformers are electrical devices that transfer energy between circuits through electromagnetic induction to step voltage levels up or down. The different vehicle types served include passenger cars, light commercial vehicles, heavy commercial vehicles, and off-highway vehicles. Various transmission types include manual transmission, automatic transmission, automated manual transmission, continuously variable transmission, and dual-clutch transmission, and they are utilized across multiple end-use industries such as automotive, industrial machinery, construction and mining, agriculture (off-highway), aerospace, and marine.
