Unimog U 4023/U 5023


Economical. Powerful. Environmentally friendly.

The all-terrain Unimog is equipped with modern and efficient Mercedes-Benz drive system technology. Tested in large-scale series production, the Euro VI engine generation sets standards for its class, taking no half-measures where conserving the environment, economic efficiency and top performance are concerned. The 4-cylinder engine with an output of 170 kW (231 hp) is particularly maintenance-friendly, economical, smooth-running and powerful. It is characterised by its high torque of up to 900 Nm as well as good figures for exhaust emissions, consumption and power-to-weight ratio. 4-valve technology and common rail injection up to 2400 bar further increase efficiency.

However, the engine is not only used for propulsion but also for braking: The two-stage decompression engine brake reduces mechanical wear and tear and makes a great contribution to economic efficiency. The exhaust gas aftertreatment system uses BlueTec 6 technology which has already proven its worth in daily use over many millions of kilometres in our heavy-duty mass-production engines. In the exhaust gas aftertreatment unit, the SCR catalytic converter reduces the nitrogen oxides to a minimum. Furthermore, the diesel particulate filter prevents almost any soot particles from escaping.
