  • Perfection in off-road use for work or expeditions
  • Rugged, efficient and reliable in challenging terrain
  • Clean and powerful in Euro VI
  • Excellent handling thanks to mid-engine configuration
The new star among Mercedes-Benz special-purpose vehicles has seen the light of day in Wörth: the largest truck plant has now embarked on series production of the new generation of the extreme all-terrain Unimog. The first unit, a U 5023 4x4 painted in arctic white, rolled off the production line on 15 July 2014 to applause from the workforce as well as from numerous guests from the worlds of politics and industry. Fresh off the production line, the newest member of the Unimog family was presented as part of a "journey through the generations", which gave a brief review of 63 years of Unimog history while providing an insight into the fascination and uniqueness of the extreme all-terrain Unimog.
Following on the heels of the new Unimog implement carrier and the new Econic, this is the third successful production launch by Mercedes-Benz Special Trucks within the space of a year – and it also brings to an end the Euro VI offensive of special-purpose vehicles in Wörth. Yaris Pürsün, Head of Mercedes-Benz Special Trucks, is delighted: "The new extreme all-terrain Unimogs set a new benchmark in the off-road sector. They impress with their ability to handle every terrain and master every challenge – be it in forest fire-fighting, flood areas or open-cast mining. The Unimog is an all-rounder, and we've been able to further improve its qualities despite the major challenges posed by Euro VI. That's a really fantastic achievement."
Fusion of proven product benefits with innovative improvements
The new generation of the extreme all-terrain Unimog combines high efficiency, cutting-edge technology and outstanding system expertise to deliver a successful overall concept that impresses with its power and performance. At the same time, the new vehicles are environment-friendly and just as rugged as their predecessors. In addition, the proven design benefits of the Unimog have been further improved in many details with the introduction of the new Euro VI engines.
Be it in forest fire-fighting, the energy sector, pipeline construction, disaster control, crane operations or expeditions, be it in rescuing people or in recovering machinery or, last but not least, in transporting passengers – wherever roads become poor and merge into open terrain, that is where the two new extreme all-terrain Unimog models come into their own. The main difference between the two variants is in the axle loads and in the permissible gross vehicle weight, which is max. 10.3 tonnes for the U 4023 and up to 14.5 tonnes for the U 5023.
This is apparent at first glance: the new vehicles have a cab-behind-engine configuration with a redesigned radiator grille and bumpers equipped with state-of-the-art bi-halogen headlamps. The new heating and air-conditioning system guarantees a pleasant working climate, while vehicle operation and handling are made easier by the clearly laid-out operating concept as well as by the front camera, which provides an extended field of vision.
The wealth of innovations also includes a new mid-engine configuration with direct power take-off for implements and an upgraded transmission. The drive comes from a high-torque Euro VI four-cylinder engine from the OM 934 engine series, which makes the Unimog suitable for motorway use with a technical top speed of 90 km/h. Standardised mounting points allow for a wide range of different implements and attachments, while the uprated vehicle hydraulics and a new engine power take-off as mechanical interface make it possible to drive powerful implements up to 600 Nm. Supreme safety is ensured by a powerful premium engine brake. In addition, extended maintenance intervals make for lower maintenance costs.
Unsurpassed off-road performance
Off-road handling has been comprehensively enhanced. This includes a lower centre of gravity, compressed-air disc brakes on all wheels, stronger axles, a revised torque tube configuration with strengthened axle connection at the front, new torsion-bar stabilisers on the front axle and dirt guards for all assemblies and components. The standard equipment includes engageable all-wheel drive, differential locks all-round, ABS and EQR (Electronic Quick Reverse).
A torsional flexibility of up to 600 mm, an axle articulation of up to 30 degrees, high angles of approach/departure of 44 degrees at the front and 51 degrees at the rear, a breakover angle of 34 degrees, an extremely high slope climbing ability of 45 degrees, a side tilting angle of 38 degrees and a fording ability of max. 1.20 m are specifications that allow safe driving in extreme off-road situations. An extra off-road transmission range covers speeds between 2.5 km/h and 35 km/h. The Tirecontrol Plus tyre pressure control system has been completely redesigned with selection options for "Rough road", "Sand" and "Road".
