Unbeatable assertiveness

No track or road is too hard for the Unimog U 4000/U 5000. Not least thanks to its low-maintenance Mercedes-Benz 4-cylinder engines with their efficient power delivery, steep torque curve and large output reserves – so that you can get going and tackle the most difficult terrain. Generous in term of power output, stingy in terms of emissions. You have the choice: either the Euro 3 engine. Or you decide on a vehicle equipped with BlueTec®, the new SCR diesel technology from Mercedes-Benz. Your benefit: the latter already meets the strict European Euro 5 emissions standard.

Mercedes-Benz engines

Take the lead – with the direct-injection, three-valve technology, exhaust-gas turbocharger, charge-air cooling, broad constant output ranges and high torque build-up. Engine output ranges from 110 kW (150 hp) to 160 kW (218 hp).

Euro 3/Euro 4

The low-emission Euro 3 engine. Or meet the Euro 5 European emissions standards with the new SCR diesel technology (Selective Catalytic Reduction). Select the one which will comply with your national emission standards.


Reduces nitrogen oxide and particulate emissions. And optimises fuel consumption without reducing the diesel engine's output.

Driving and working modes

The proper engine mode at the push of a button to suit the job to be done. Driving mode benefits from the elasticity of the engine speeds for road trips. Working mode ensures guarantees minimal rev speed deviations.
