Class 8 engines dominated the Heavy Duty Engines Market in 2024, accounting for 78% of the overall share. These engines are widely used in long-haul freight trucks and heavy industrial vehicles due to their superior torque and durability. Demand is driven by growing freight transportation, construction, and infrastructure expansion across North America and Asia. Class 7 engines, though smaller in size, are gaining attention for medium-duty applications like regional logistics. However, stringent emission regulations and the shift toward cleaner, fuel-efficient diesel and hybrid powertrains continue to boost the adoption of advanced Class 8 engines.
For instance, Detroit lists the DD15 with 425–505 hp and 1,550–1,850 lb-ft torque, a common Class 8 fit.
By Horsepower
Engines rated between 400–500 horsepower led the market with a 42% share in 2024, owing to their balanced power output and efficiency. These engines are preferred in long-haul and heavy construction applications that require consistent performance and lower maintenance. The segment benefits from increasing adoption of turbocharged and electronically controlled fuel systems that enhance fuel efficiency and reduce emissions. Engines above 600 horsepower are also seeing gradual demand rise in mining and high-capacity transport fleets, driven by the need for higher towing capabilities and productivity improvements in off-highway operations.
For instance, Cummins X15 Efficiency Series is rated at 400–500 hp with 1,450–1,850 lb-ft peak torque.
By Application
The logistics segment accounted for 46% of the Heavy Duty Engines Market in 2024, leading overall demand. This dominance stems from rising e-commerce activities, international freight movement, and fleet modernization. Logistic operators are investing in high-torque diesel engines to ensure efficient cargo handling over long distances. Construction and mining applications are also growing due to rapid urbanization and resource extraction projects. Agricultural applications are seeing adoption of engines with better fuel economy and emission control systems, particularly in developing economies focused on mechanized farming practices.
Key Growth Drivers
Rising Demand for Freight and Logistics
The expansion of global trade and e-commerce has increased the need for reliable heavy-duty transport vehicles. Fleet operators are upgrading to high-performance engines to improve load capacity and operational efficiency. This growth is further supported by the rise in cross-border trucking and last-mile delivery services. Logistics networks in North America, Europe, and Asia-Pacific continue to expand, boosting demand for powerful diesel and hybrid engines that can handle long-distance routes while meeting stricter emission and fuel efficiency standards.
For instance, PACCAR’s MX-13 can be specified to 510 hp and 1,850 lb-ft for heavy-haul fleets.
Infrastructure and Construction Expansion
Rapid infrastructure growth across developing economies is driving demand for heavy-duty engines in construction and mining equipment. Governments are investing heavily in road, bridge, and industrial development projects that require high-torque machinery. Engine manufacturers are responding with models offering enhanced durability and performance under extreme conditions. The surge in off-highway vehicle production and heavy machinery rentals is fueling sustained demand for advanced heavy-duty engines, particularly in Asia-Pacific and the Middle East regions.
For instance, Komatsu’s SAA6D140E-7 in the HD325-8 truck is rated at 518 hp (386 kW) at 2,000 rpm.
Technological Advancements in Engine Design
Manufacturers are adopting technologies such as turbocharging, electronic fuel injection, and hybrid integration to enhance engine efficiency. These advancements improve fuel economy, extend engine life, and reduce carbon emissions. The integration of telematics and IoT-enabled monitoring systems allows predictive maintenance and real-time diagnostics, reducing downtime. Growing regulatory pressure to meet emission standards like Euro VI and EPA Tier 4 is also prompting innovation in clean-combustion and after-treatment systems, driving the modernization of heavy-duty engine platforms.
Key Trends and Opportunities
Shift Toward Electrification and Alternative Fuels
The transition toward low-emission transportation is creating strong opportunities for hybrid and alternative-fuel engines. Manufacturers are developing engines compatible with biofuels, LNG, and hydrogen to meet sustainability targets. Electric heavy-duty powertrains are gaining attention, especially in urban logistics and port operations. This trend aligns with global decarbonization initiatives and fleet electrification programs supported by government incentives, pushing traditional engine producers to diversify product portfolios and integrate cleaner technologies into heavy-duty applications.
For instance, BYD’s Class 8 8TT has been produced with different battery and torque ratings over its lifespan, including a version with a 422 kWh battery, 483 hp, and 664 lb-ft of torque, as well as configurations with 435 kWh and 563 kWh battery packs.
Digitalization and Smart Fleet Management
The adoption of IoT-based diagnostics and connected systems is transforming engine management in logistics and industrial sectors. Smart sensors monitor performance, enabling predictive maintenance and reducing operational downtime. Fleet operators use data analytics to optimize fuel consumption and vehicle utilization. These technologies not only improve profitability but also extend engine life. The increasing use of digital fleet management platforms presents a key opportunity for manufacturers to offer engines integrated with software-based performance tracking systems.
For instance, as of August 2025, MAN’s parent company, TRATON, reports approximately 1.15 million connected vehicles in operation across its brands.
Key Challenges
Stringent Emission Regulations
Global emission standards are becoming increasingly strict, requiring significant R&D investment to comply with carbon reduction norms. Meeting requirements such as Euro VI, EPA Tier 4, and China VI adds production complexity and cost. Smaller manufacturers struggle to adapt due to high development expenses. The shift toward cleaner technologies demands redesigned components, advanced filtration systems, and costly after-treatment solutions, which can limit profit margins and delay product launches in cost-sensitive markets.
High Production and Maintenance Costs
Heavy-duty engines are expensive to manufacture and maintain due to complex designs and advanced materials. The rising cost of raw materials, precision components, and emission-control systems increases overall production costs. Maintenance and repair also require specialized skills, further driving operational expenses for fleet operators. Economic slowdowns or fluctuating fuel prices can reduce new vehicle purchases, affecting engine demand. Balancing durability, performance, and affordability remains a persistent challenge for industry players.
