This central engine relocation meant redesigning the flexible Unimog frame, fitting a long shaft to drive the coolant radiator fan and redesigning the transmission connection to the engine.īonuses from this redesign were improved weight distribution: shifting some engine weight off the front axle and allowing easy location of an engine power take off right at the back of the cab – not underneath it. M-B engineers went a step further and located the new engine a full one-metre aft. The previous powerplants were smaller 4.25L and 4.8L engines.Įven with a cab lift, it was clear that accommodating a larger engine and all the Euro VI emissions equipment, plus a larger radiator under that snub nose was going to be difficult. Mercedes-Benz chose the Euro VI-compliant, four-cylinder, OM934 5.1-litre engine with 170kW and 900 Nm as the new powerplant for both Unimogs. The trigger for the engine change was Euro VI emissions levels that dictated cooled exhaust gas recirculation (EGR), a diesel particulate filter (DPF) and selective catalytic reduction (SCR).

Inside that familiar envelope is a revised powertrain. Gross mass ratings for the U4023 are 7.5-10.3 tonnes, depending on vocation and for the U5023, 12.5-14.5 tonnes.īecause post-2014 Unimog models have Euro VI emissions compliance that isn’t necessary in Australia there was no legal reason to hurry the introduction of these vehicles Down Under: hence their delayed arrival here.Ĭarried over from the previous generation are the design of the familiar cab sheet metal, flexible chassis, high-ground-clearance portal-hub axles, all-coil-spring suspension, eight-speed main transmission and low-range gearing, but virtually everything has been upgraded and strengthened. The latest Unimog range was released in Europe in 2014 and retains the previous model numbers of U4023 and U5023. New Unimogs can be purchased in one of two series: medium series 405, also known as the UGN ('Geräteträger' or equipment carrier), and heavy series 437, also known as the UHN ('Hochgeländegängig' or highly mobile cross country).The latest Unimog looks familiar, but hides significant powertrain changes behind that rugged façade. In Western Europe, they are commonly used as snowploughs, municipal equipment carriers, agricultural implements, forest ranger vehicles, construction equipment or road-rail vehicles and as army personnel or equipment carriers (in its armoured military version). With their very high ground clearance and a flexible frame that is essentially a part of the suspension, Unimogs are not designed to carry as much load as regular trucks.Due to their off-road capabilities, Unimogs can be found in jungles, mountains and deserts as military vehicles, fire fighters, expedition campers, and even in competitions like truck trials and Dakar Rally rally raids. It was designed with rear-wheel drive and switchable front-wheel drive, with equal-size wheels, in order to be driven on roads at higher speeds than standard farm tractors. under licence from 1968 until 1983 (with some extra units built until 1991 off the assembly line from parts in stock) in the González Catán factory near the city of Buenos Aires.The first model was designed by Albert Friedrich and Heinrich Rößler shortly after World War II to be used in agriculture as a self-propelled machine providing a power take-off to operate saws in forests or harvesting machines on fields. Unimogs were also built in Argentina (first ever country to do so outside Germany) by Mercedes-Benz Argentina S.A. plant assembles Unimogs in Aksaray, Turkey. Currently, it is built in the Mercedes-Benz truck plant in Wörth am Rhein in Germany. Daimler-Benz took over manufacture of the Unimog in 1951 and first produced it in the Mercedes-Benz Gaggenau plant.

Production started in 1948 at Boehringer in Göppingen. The name Unimog is pronounced in German and is an acronym for the German 'UNIversal-MOtor-Gerät', Gerät being the German word for device (also in the sense of machine, instrument, gear, apparatus). In the United States and Canada, the Unimog was sold as the Freightliner Unimog. Unimog is a range of multi-purpose all-wheel drive medium trucks produced by Daimler (formerly Daimler-Benz) and sold under the brand name Mercedes-Benz.
