Updated Unimog will be more enviroment friendly

Updated Unimog will be more enviroment friendly

The outstandingly mobile off-road Unimog with its new reference numbers U 4023 and U 5023 as the follow-up models for the U 4000 and U 5000 is now more environmentally acceptable and efficient, but still just as mobile off the road as its predecessors and even stronger – that means better all round. It is fitted with the new four-cylinder BlueEfficiency Power BlueTec 6 engine with an output of 170 kW (230 hp) and a strong torque of 900 Nm. The Unimog transmission has been improved and uprated so that the gear changing times are shorter with an increased life span. In future the gears will be changed using the pitman arm on the steering column and this also includes the electronic quick reverse function (EQR). As up to now, there are eight forward and six reverse gears available as well as the optional crawler gears for off-road use with a speed range between 2.5-35 km/h. The main difference between the two big Unimog vehicles lies in their axles and frames i.e. their axle loads and the gross vehicle weights which is a maximum of 10.3 tonnes for the U 4023 and 14.5 tonnes for the U 5023.

This cab is first class – it has left its mark on the appearance of the outstandingly mobile off-road Unimog since 1974. The designing engineers were confronted with the challenging task of installing technology complying with Euro VI and they succeeded by repositioning the engine one metre further back under the cab and this is now the core of the new concept. In comparison with its predecessor, the new cab has been lengthened by 120 mm and is slightly higher – and by moving the transmission controls from the central console to the pitman arm on the steering column there is much more space in the interior of the cab.

This cab has also been upgraded with its new fittings: The multifunction steering wheel, adjustable steering column, pitman arm control, multifunction touch-keys and instrument cluster with a large display as well as a new stronger heating and ventilation system provide the very best conditions for the driver. The central tire inflation system "Tirecontrol Plus" has been redesigned so that the correct tire pressure for the prevailing conditions can be chosen simply and easily in the display with the pre-programmed modes "road", "sand" and "bad surface". From the outside the dynamic design of the radiator and the new bumpers with modern headlamps show at the first glance that here there is a new generation of the Unimog on the job. Also the access to the cab is completely new with easy to master and safe steps, two or three depending on what the customer requires.
