MAN Engines at Agritechnica preview

MAN Engines gave us a preview of what we will see at Agritechnica. A balanced offering, which includes large-calibre engines for traction, stationary gas engines, battery packs, and the TGS 18.540 4×4 BL SA truck.

Let’s start with the D4276 and D2676 for tractors and harvesters

At Agritechnica 2025, MAN Engines will be presenting strategically further developed drive solutions under the keynote theme “Powering the green transformation – off-road solutions for the future”, which are specifically in line with the trade fair motto “Touch Smart Efficiency”.

“MAN Engines is once again showing how smart innovations and well-thought-out system solutions pave the way for future-proof agricultural technology,” says Reiner Roessner, Head of Sales at MAN Engines. As a bridging technology, the stationary MAN gas engines also make an important contribution to the transformation of the energy sector and enable a noticeable reduction in CO₂ emissions. Solutions from MAN Engines thus stand for future-oriented and responsible agriculture.

“Whether it’s high-performance engines for agricultural machinery, innovative gas engines for power generation, genuine remanufactured units, the new MAN BatteryPack or the MAN Truck specially modified for agriculture and forestry – at Agritechnica 2025 we will be showcasing solutions for every step of the harvest chain: from field work to energy supply and efficient transport,” says Hubert Gossner, Head of Off-Road & Power MAN Engines.

In the case of the MAN D4276 engine, the integration of the latest generation of control units has resulted in a comprehensive optimization of the variants with variable and fixed turbine geometry. This revision enables more efficient combustion and higher performance values, and initial test bench results show fuel savings of up to three percent.

The MAN D2676 engine is also receiving a comprehensive update, which relies on a new engine control unit and a completely revised basic engine. The increase in power from 383 kW (521 hp) to 404 kW (549 hp) is made possible by a new crankshaft, revised combustion, camshaft and pistons together with a modified injection system, oil module and fuel filter. The higher compression ratio ensures reduced consumption of up to seven percent, depending on the respective application and operating conditions. New engine maps and an adapted design lead to a noticeable increase in efficiency and performance.

With the integration of functional safety in accordance with ISO 26262 into the development of the D4276 and D2676 engines, another forward-looking step has been taken. This aspect of modern vehicle technology ensures that safety-relevant systems react reliably and in a controlled manner even in the event of a fault. The inclusion of this standard underlines MAN Engines’ claim to combine technological innovation with the highest level of system integrity.

The MAN D4276 and MAN D2676 engines – like all off-road engines from MAN – are prepared for future and alternative fuels. They are developed and built at the MAN competence centre in Nuremberg, where innovations in diesel, natural gas, biogas, hydrogen and battery-electric drives are being promoted.

On display at Agritechnica are an example of the modern product portfolio: a MAN D2676 engine with a supporting structure of the oil pan used in the Fendt 1000 Vario tractor. This engine will be exhibited together with an EU Stage V exhaust aftertreatment system, consisting of an SCR catalytic converter and diesel particulate filter. Furthermore, a cutaway model of the MAN D4276 allows insights into the interior of the most powerful production in-line six-cylinder engine from MAN Engines in the off-road sector.

The preview of the MAN E3872

Another exhibit at Agritechnica is the MAN E3872 gas engine, which has been in series production since mid-2024. Against the background of the current biomass package of the German government, it in twin and triple pack configurations represents an ideal solution for the requirements for higher outputs with increasing flexibility. The modular combination of several of these modern gensets with an output of 735 kW makes it possible to cover important power ranges in the field of combined heat and power – such as >1 MW or 2 MW total output – while at the same time improving load stepping capability, high availability and reduced service times due to the redundancy of individual motors.

The development of this 30-litre engine is based on the experience of millions of operating hours of the 26-litre MAN E3262 variant. The complete redesign resulted in an engine that sets new standards in its design and performance and clearly stands out from previous generations. In addition to increases in the strength of the crankcase, elementary differences mainly relate to the revision of the turbocharger concept, the combustion process and the cylinder heads.

The MAN E3872 achieves an electrical efficiency of up to 44.4% in the natural gas variant and an overall efficiency of up to 90% in combined heat and power operation. In biogas operation, the values are up to 43.5% electric and 89% total, making the motor ideal for both classic CHP applications and for use in biomass plants eligible for funding.

Depending on the version, the MAN E3872 falls below the strict emission limits of 250 mg and 500 mg NOx per standard cubic metre – and thus meets the current requirements for use as part of the German government’s biomass package.

What’s next?

So, in the next article, we will update you on the Genuine Remanufactured Engines for agricultural machinery, the BatteryPack – Energy storage solution for mobile and industrial applications, and MAN’s TGS 18.540 4×4 BL SA: truck specially designed for agricultural applications.
