At Agritechnica 2025, Man Engines presented power units specifically designed to meet the performance requirements of the entire agricultural harvesting chain. From high-efficiency six-cylinder engines to new energy storage systems, the German company is focusing on integrated technologies for more sustainable and efficient mechanization
“Powering the Green Transformation” was the slogan under which MAN Engines appeared at Agritechnica 2025. The Italian translation of the slogan—“Providing energy for the green transformation”—highlights the German company’s determination to renew both its diesel and gas engine offerings while also introducing new solutions in the fields of electrification and energy storage systems. The resulting powertrain range is designed to cover the entire harvesting chain, from field work to power generation and logistics, addressing the needs of an agricultural sector in transition, called upon to combine productivity, efficiency, and sustainability.
Taking center stage in the engine lineup were the “D4276” and “D2676” units, two in-line six-cylinder engines already well known in the industry, now updated through targeted technical revisions aimed at improving efficiency, performance, and reliability. The “D4276,” used by brands such as Fendt and Claas, receives a new generation of control units as well as variable- or fixed-geometry turbochargers optimized for more efficient combustion and fuel savings of up to three percent. With a displacement of 16.2 liters, it represents the benchmark among high-power six-cylinder engines, making it ideal for harvesting machines and tracked tractors.
The “D2676,” in its new 404 kW (549 hp) version, benefits from an increase in maximum power resulting from a thorough redesign of the crankshaft, camshafts, pistons, and injection system, along with a new oil module and fuel filter. These changes, combined with updated engine mapping, deliver fuel consumption reductions of up to seven percent and more responsive, smoother behavior even under variable loads. Both engines are now developed in compliance with the ISO 26262 functional safety standard, ensuring full system reliability even under critical conditions.
Another key highlight from MAN Engines is the new “E3872,” a 30-liter gas engine that entered production in 2024. Derived from the experience gained with the “E3262” unit, it is now one of the most efficient engines in its class for cogeneration plants and biomass applications. In natural gas configuration, it achieves electrical efficiency exceeding 44 percent, rising to up to 90 percent in combined heat and power operation.
In biogas configuration, efficiency figures remain at similarly high levels—around 43.5 percent electrically and 89 percent overall. Its modular design allows multiple units to be operated in parallel, in “twin” or “triple pack” configurations, for total outputs exceeding two megawatts, offering advantages in terms of flexibility, redundancy, and reduced maintenance downtime. The engine already complies with the emission thresholds set by the German government’s biomass package, with nitrogen oxide emissions below 250 mg/m³, positioning it as a solution for decarbonizing agricultural energy processes.
Sustainability is also addressed through the “Genuine Remanufactured” regeneration solutions, showcased via a reconditioned structural version of the “D2676.” This initiative enables MAN to offer customers fully overhauled, bench-tested engines with the same performance and warranty as new units, but with significant economic and environmental savings. It is a solution designed to extend the service life of existing agricultural machinery and reduce the environmental impact associated with manufacturing new engines, in line with the Group’s circular economy strategy.
Among the most noteworthy innovations presented at the show in the area of sustainable transformation is the “BatteryPack,” a modular energy storage system intended for mobile and industrial applications. Based on nickel-manganese-cobalt cells, the battery pack delivers high energy density while maintaining low weight and compact dimensions. The intelligent battery management system (BMS) continuously monitors the condition of individual cells, keeping them within the optimal thermal range through an integrated heating and cooling circuit.
The BatteryPacks are produced at MAN’s Nuremberg plant, which has now been transformed into a center of excellence for battery technologies and internal combustion engines. Each unit undergoes more than 400 checks during final testing, ensuring quality standards equivalent to those of the automotive industry. The modular nature of the configurations allows integration across a wide range of vehicles, spanning construction and rail sectors and now also extending into agriculture.
Finally, demonstrating coverage of the entire agricultural production chain, the star of the MAN stand was the new “TGS 18.540 4×4 BL SA,” a truck specifically designed for agricultural and forestry applications. Equipped with permanent all-wheel drive, wide-section agricultural tires, and off-road driving programs, the vehicle ensures traction and stability even on challenging terrain. The load-sensing hydraulic system and the drawbar hitch with forced steering enable safe operation with agricultural trailers and towed equipment.
The cab interior, designed for driver comfort, features the MAN “SmartSelect” system with a professional display and ergonomic controls specifically tailored for agricultural applications. Also included are engine start-stop systems (“ACC Stop & Go”) and a rear-view camera system to enhance safety standards. Classified as an agricultural or forestry vehicle, this TGS model offers homologation advantages, including exemption from holiday traffic bans and tachograph requirements.
