Chassis expertise: Knows virtually no limits. Not even the tree line.

The unique off-road capability of the Unimog starts with its suspension system: The torsionally flexible frame with three-point mounting of the cab, engine and transmission system, as well as the suspension mounting with torque tube engineering, wishbone steering and coil springs, ensure articulation of up to 30°. All-wheel drive, single tyres, TireControl tyre pressure control system plus differential locks ensure maximum off-road traction. And the vehicle's low centre of gravity ensures stability even on extremely steep slopes. When off-road, the Unimog also benefits especially from its ground clearance of up to half a metre. This is made possible by its portal axles as well as by the positioning of all major assemblies above the lower edge of the frame.

System expertise: the Unimog is more than just a vehicle.

A true utility vehicle that is fully operational even in the most remote areas – the Unimog is the embodiment of off-road mobility. Even in the middle of the countryside, mechanical, hydraulic and electric drives deliver the right power for different implements and bodies. The well thought-out drive concept predestines the vehicle for a wide variety of tasks and applications. Three attachment spaces with standardised connection points make it easy to attach bodies and change implements. Mercedes-Benz has been cooperating with international equipment and body manufacturers for decades and combines in the Unimog the experience and competence of specialists as well as the expertise of competent Unimog partners.

proves its off-road qualities when it really counts.

Product benefits

Off-road capability.

No matter the obstacles you need to overcome, the Unimog is built to master almost every imaginable obstacle.

Its engageable all-wheel drive ensures the vehicle steadily continues, even on difficult terrain. The Unimog is equipped with two features to ensure greater traction: differential locks can be engaged to prevent wheels from spinning. And the central tyre control system, TireControl plus,  adjusts tyre pressure to the ground beneath the wheels. The single-tyre principle is also well thought-out: The rear wheels follow in the tracks made by the front wheels and are, therefore, able to use the firmness of the surface already compacted by them.

  • Axle articulation up to 30°
  • Torsional flexibility up to 600 mm diagonally
  • Engageable differential locks
  • Tyre pressure control system
  • TyreControl plus single tyres for increased traction and protection of the ground
  • Can cross fords of up to 1.20 m

Unique frame concept.

Flexible and robust in operation: The key factor in the off-road ability of the Unimog U 4023 and U 5023 is the offset vehicle frame. Thanks to its torsional flexibility in combination with torque tube technology and the three-point mounting of engine, transmission, cab and body, a diagonal torsion of up to 600 mm is possible. As the frame is fully welded, it permanently withstands torsion. At the same time, the frame offset gives the vehicle a low centre of gravity with high ground clearance.

A further plus in off-road operations: Axle suspension with torque tube. By connecting the axles to the transmission using torque tube and thrust ball, axle articulation of up to 30° can be attained. And encapsulation protects the drive shaft against contamination with dust, water and other outside influences when driving off the beaten track.

High ground clearance.

The intelligent response to any challenge. The typical Unimog portal axles ensure high ground clearance but with a low centre of gravity. And the asymmetrical arrangement of the axle differentials makes it easier to drive over obstacles. The suspension mounting has been strengthened and defies even the greatest stresses and strains. The axle design is also really robust: It makes great standard load capacities possible.

Steep climb.

The short frame overhang at front and rear provides wide approach/departure and breakover angles. This means: there's almost no terrain, however steep it may be, that poses a problem for the Unimog. This vehicle is equally at home in floods and in waterlogged areas: waterproofed assemblies, a vertical air-intake pipe and high vent pipes allow the Unimog to ford water depths of up to 80 cm (optionally 120 cm).


Large ground clearance, raised intake pipe and protected assemblies for fording up to a depth of 800 mm (1,200 mm as an option).

Single tyres.

The principle: the rear wheels follow in the tracks made by the front wheels. This improves traction and protects the terrain.

Optimum traction.

Thanks to TireControl plus, the Unimog always has the right tyre pressure on the road.

TireControl plus.

The switch logic of the tyre control system allows the user to choose between the pre-set "Road", "Sand" and "Rough" modes. This means the correct mode for the current road surface can be set intuitively, making operator error virtually impossible. TireControl  also brings benefits for nature: driving off-road with lowered tyre pressure improves traction while reducing the impact on the land.

A performance that breaks records.

6,694 metres above sea level – you can't get more off-road than that. Never before has a wheeled vehicle driven at such an altitude. Matthias Jeschke and his expedition team achieved just that on 13 December 2019 with their two Unimog vehicles, breaking the world altitude record for wheeled vehicles in Chile. 

Unimog impresses TV presenters.

Speed. Ouput. Driving enjoyment. Jean Pierre "JP" Kraemer and Matthias Malmedie know what they're talking about when it comes to vehicles. Both have already put many vehicles through their paces on the German Mercedes-Benz YouTube channel called “Let’s drive Mercedes”. However, neither of them had ever tested a Unimog from Mercedes-Benz. And it simply leaves the  professionals speechless.

Body variants.

The extreme off-road Unimog can work in places others cannot even get to.

The Unimog is vehicle and tool all rolled into one. The prerequisites for this are defined by the existing spaces for implement carriers, as well as interfaces and drives for fixed or interchangeable devices. The Unimog has two different transmission power take-offs and one engine PTO. A vehicle hydraulic system to power different implements and continuous consumers is available as optional equipment. Standardised sockets provide electric power. The body mounting space can be used is lots of different ways: The possibilities range from platform bodies and box bodies to special solutions for specific requirements.

  • Defined attachment points for quick and easy implement changes
  • Two transmission PTOs and one engine PTO
  • Vehicle hydraulics
  • Standardised sockets

Quick implement change.

Defined mounting points make it easy and quick to switch implements and to fasten a wide range of attachments securely and safely.

1    Front mounting brackets for compressors or units
3    Cable winch brackets
4    Frame mounting brackets
5    Mounting parts for platform bodies or box bodies
6    Floor assembly for special bodies

Powerful transmission and engine PTOs.

The engine-driven power take-off opens up a wide range of potential applications, for example for the operation of a firefighting or hydraulic pump. The proven transmission power take-offs can also be integrated into the extreme all-terrain Unimog as an option, for example a fast variant for hydraulic pumps and a very fast variant for firefighting pumps. The design of the sub-frame makes the transmission power take-offs easy to access for a wide range of potential uses.

Vehicle hydraulics and electrical interfaces.

Attachments such as cable winches, snowploughs, front loaders or hydraulic tools can be powered by the vehicle's hydraulics. The single-circuit hydraulics provide an operating pressure of 240 bar at a delivery volume of 60 l/min and 24 kW pump output. Standard sockets are positioned on the front and at the rear end. Four standard sockets are available to provide the power supply to the implements.

Off-road power.
