2016 Extreme All-terrain Mercedes-Benz Unimog

The Euro VI diesel engine is the heart of the new mid-engine concept. The engine used here is the new high-torque OM 934 BlueTec 6 engine; a four-cylinder unit with an output of 170 kW (231 hp) and a displacement of 5.1 l. Exceptionally efficient, the assembly provides a higher torque of 900 Nm, which is available consistently over the entirety of the principal driving range from 1200 rpm to 1600 rpm. The technical top speed of 90 km/h is quite adequate for longer journeys and motorway driving.

The transmission of the Unimog has been optimised and uprated, resulting in shorter shift times whilst also extending its service life. The transmission is operated via a steering-column lever, which is also used to control the electronic quick reverse (EQR) function. As in the previous version, eight forward and six reverse gears are available and there is also an optional off-road group for off-road use in the speed range between 2.5 and 35 km/h.

Safety has also been improved: the new engine brake is a double-speed decompression brake which, in the case of the OM 934, develops braking power of up to 180 kW. Each cylinder in the engine has its own engine brake unit. The high braking efficiency considerably reduces wear and tear on the wheel brake systems, thus greatly improving the overall economy. Offroad ABS comes as standard.

As with all Mercedes-Benz commercial vehicles, the new model designations of the big Unimog include the horse power number: 230 in this case. The first two digits of the designation stand for the vehicle type.

The biggest differences between the two models come in the form of the axles and frames, which thus affect the axle loads and gross vehicle weight. In the case of the U 4023, this is a maximum of 10.3 t, for the U 5023 a maximum of 14.5 t.
