Heavy-duty engines refer to engines used in heavy-duty vehicles with a gross vehicle weight of 10,000 pounds or more. These engines power heavy-duty vehicles in sectors such as marine, locomotive, mechanical drive applications, and electrical power generation.
The primary types of heavy-duty engines are class 7 and class 8 vehicles. Class 7 heavy-duty engines are vehicles designed to carry heavy loads, usually with three or more axles and a gross vehicle weight rating between 26,001 pounds and 33,000 pounds. Commonly used class 7 vehicles include garbage trucks, city transit buses, and street sweepers. Various horsepower categories include below 400hp, 400hp-500hp, 500hp-600hp, and above 600hp. They are employed across diverse end-users in agriculture, mining, construction, transportation and logistics, and other sectors.
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 influenced the heavy duty engines market by increasing costs for imported engine components, raw materials, and precision manufacturing equipment. These impacts are most visible in class 7 and class 8 vehicle segments across north america and asia pacific regions. Higher costs have affected equipment pricing and replacement cycles. On the positive side, tariffs are promoting domestic engine manufacturing and regional sourcing of critical components.
The heavy duty engines market research report is one of a series of new reports from The Business Research Company that provides heavy duty engines market statistics, including heavy duty engines industry global market size, regional shares, competitors with a heavy duty engines market share, detailed heavy duty engines market segments, market trends and opportunities, and any further data you may need to thrive in the heavy duty engines industry. This heavy duty engines market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.
The heavy duty engines market size has grown strongly in recent years. It will grow from $54.84 billion in 2025 to $58.8 billion in 2026 at a compound annual growth rate (CAGR) of 7.2%. The growth in the historic period can be attributed to growth in infrastructure development, expansion of mining activities, demand for heavy commercial vehicles, reliance on diesel powered engines, growth in power generation projects.
The heavy duty engines market size is expected to see strong growth in the next few years. It will grow to $78.37 billion in 2030 at a compound annual growth rate (CAGR) of 7.4%. The growth in the forecast period can be attributed to stringent emission regulations, adoption of alternative fuel engines, growth in logistics and freight transport, modernization of heavy vehicle fleets, investments in industrial machinery. Major trends in the forecast period include rising demand for high horsepower engines, focus on fuel efficient engine designs, expansion of engines for construction equipment, growth of engines for power generation, increasing adoption of emission compliant engines.
The growing construction industry is expected to drive the growth of the heavy-duty engines market. Construction, encompassing residential, commercial, institutional, and industrial projects, requires engines capable of handling large loads and powering equipment such as concrete mixers for major projects. For instance, in February 2025, the US Census Bureau reported that construction spending in December 2024 reached a seasonally adjusted annual rate of $2,192.2 billion, a 4.3% increase from December 2023's $2,101.3 billion. This expansion in construction activity is fueling demand for heavy-duty engines.
Key companies in the heavy-duty engines market are developing next-generation engines to enhance efficiency, reduce emissions, and comply with evolving industry regulations. Next-generation heavy-duty engines integrate advanced technologies and materials to improve fuel efficiency, performance, and environmental sustainability. For example, in March 2024, Cummins, a US-based engine manufacturer, launched its HELM 15-liter diesel engine, compliant with U.S. EPA and CARB 2027 regulations. This fuel-agnostic platform supports biodiesel blends and renewable diesel, meeting future emissions standards while enhancing operational efficiency.
In July 2024, Cummins Inc. partnered with Vale SA, a Brazil-based mining company, to develop dual-fuel haul trucks powered by ethanol and diesel. The collaboration integrates Cummins dual-fuel technology into large Komatsu mining trucks, aiming to reduce CO2 emissions by up to 70% while maintaining existing fleets and fueling infrastructure, supporting sustainable and scalable mining operations.
