AGCO Power’s new CORE80 engine makes its world debut at Agritechnica 2025 alongside the fifth-generation Fendt 800 Vario tractor. Designed as a low-rpm engine, the development goal was to deliver an exceptionally fuel-efficient power source for modern tractors.
With CORE80, AGCO Power’s new engine family now offers three options for different tractor sizes: the four-cylinder CORE50 (165 kW / 950 Nm), the six-cylinder CORE75 (250 kW / 1450 Nm), and the newest variant, CORE80, rated at 252 kW with 1680 Nm of torque.
“We increased the new model’s output with targeted component changes: a longer stroke, steel pistons to withstand higher cylinder pressures, and a variable-geometry turbocharger that adds both power and strong engine-braking performance,” says Markus Iivonen, Module Lead Engineer at AGCO Power.
All CORE engines are compatible with renewable HVO fuels. In the future, they can also be adapted to run on hydrogen, ethanol, methanol, and biogas.
AGCO Power CORE80
- Next-generation diesel engine built on a low-rpm concept
- Low operating costs thanks to excellent efficiency
- The CORE family’s fuel economy is proven in independent DLG PowerMix tests
- The new CORE80 goes into service first in the new Fendt 800 Vario Gen5 tractor
Low fuel consumption and minimal maintenance costs
Outstanding fuel economy starts with a powertrain and engine built around the low-rpm concept. CORE80’s rated speed is 1700 rpm, whereas conventional tractor diesels are typically operated at 2000–2100 rpm. Peak power is delivered at a low 1500–1700 rpm, and maximum torque is available at 1200–1400 rpm.
“Thanks to the low-rpm concept and high torque, CORE80 achieves excellent efficiency, which keeps operating costs down and reduces CO₂ emissions to a minimum. We’ve met emissions targets without exhaust gas recirculation. The engine also avoids twin turbos, keeping the design simple and reliable,” Iivonen explains.
Usability is further enhanced by up to 90 kW of engine braking power made possible by the variable-geometry turbocharger (VGT).
Developing a completely new diesel engine family has been a major R&D undertaking for AGCO Power—and a rare one globally.
“For high energy demands in agriculture and heavy industrial applications, there is currently no broadly viable replacement power source, so our conclusion was clear: diesel still deserves development. The new CORE family is more compact than previous diesels, more powerful, and significantly more fuel-efficient—ensuring a long service life in the market,” Iivonen says.
Economy confirmed in independent DLG PowerMix tests
The efficiency of Fendt’s powertrain based on CORE engines has already been proven in the demanding, independent PowerMix tests by the German Agricultural Society (Deutsche Landwirtschafts-Gesellschaft, DLG). While a DLG PowerMix report for the Fendt 800 Vario Gen5 with the AGCO Power CORE80 is not yet available, smaller Fendt models using CORE50 and CORE75 engines have been tested.
Fendt 724 Vario Gen7.1 with AGCO Power CORE75
- Lowest fuel consumption in its power class in DLG PowerMix testing
- 242 g/kWh fuel consumption (+24.2 g/kWh AdBlue)
- Outstanding 326 g/kWh in transport at 60 km/h
“The broad DLG tests clearly show the energy efficiency of the Fendt powertrain and CORE. We have focused on optimizing fuel economy and overall efficiency, as well as response to rapidly changing loads. Throttle response is quick—helped by the VGT turbocharger,” Iivonen notes.
The CORE80’s strong fuel economy also shines in transport work—tasks typically common for high-horsepower tractors. Thanks to the Fendt 800 Vario Gen5, the VarioDrive transmission, and AGCO Power’s low-rpm engine, the tractor can travel at 60 km/h at an economical 1450 rpm.
According to Fendt’s calculations, for example, a Fendt 700 Vario equipped with the CORE75 can save up to €16,000 over 5,000 operating hours when diesel is €1.60/l and AdBlue €0.65/l.
Leaving out exhaust gas recirculation simplifies the engine and contributes to low fuel consumption. Emissions are minimized with a high-efficiency aftertreatment system comprising a diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and selective catalytic reduction (SCR) with AdBlue.
“This is also the right solution for users’ total cost of ownership, because both CO₂ emissions and fuel consumption have been reduced to low levels,” Iivonen adds.
The smaller CORE50 and CORE75 will also be shown at Agritechnica. The new, low-emission and energy-efficient CORE engines are already available in Fendt models: the 5-liter four-cylinder AGCO Power CORE50 powers the Fendt 500 Vario Gen4 and Fendt 600 Vario series, while the 7.5-liter CORE75 is used in the Fendt 700 Vario Gen7 series. All CORE engines are manufactured at AGCO Power’s Linnavuori plant in Nokia, Finland.
