Drive concept.

Its robustness, reliability and versatility have made the "universal power tool", as it was originally called, the work and transport vehicle of choice worldwide for decades when difficult operating conditions require a reliable helper. Despite its broad scope of practical skills, it has been possible to keep its dimensions compact – and it's for this specific reason that the highly off-road-capable Unimog can make use of its effectiveness virtually wherever it is needed.

Areas of application.

The Unimog is vehicle and tool all rolled into one. Thanks to its uncompromising off-road capability, it transports equipment, material and crew off the beaten track to the job site.

Once there, it reliably delivers first-class work. 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 highly off-road capable 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 particularly flexibly: The possibilities range from platform bodies and box bodies to special solutions for specific requirements. All this together results in a strong and highly mobile workshop with which work assignments can be carried out safely and reliably.


The highly off-road-capable Unimog is equipped with modern and efficient Mercedes-Benz drive system technology. Tested in large-scale series production, the Euro 6 engine generation sets standards for its class and takes no half-measures where conserving the environment, economic efficiency and top performance are concerned. The 4-cylinder engine with an output of 170 kW is particularly maintenance-friendly, economical, smooth-running and powerful. It is characterised by its high torque of up to 900 Nm as well as good figures for exhaust emissions, consumption and power-to-weight ratio. 4-valve technology and common rail injection up to 2400 bar further increase efficiency.

Get in, feel good, get going: The cab brings together the result of decade-long vehicle design and construction. It offers a comfortable sitting position in the low-vibration area behind the front axle – a valuable support especially when off-roading. All the settings can be registered quickly in the large instrument cluster. This make a considerable contribution to safety and user-friendliness. This way, work and comfort go hand in hand in the Unimog. Because the faster and more intuitively the driver can operate the many different driving and working functions, the safer and more reliable off-road use will be.


If the Unimog is not only to transport as much material as possible to places of work, but also teams of up to 7 persons, the crewcab is a valuable asset. It has an additional four-seater rear bench seat - each seat equipped with its own seat belt and with optimum comfort features. Alternatively, for air-sprung single seats are optionally available. The crewcab makes it easy to get to work sites in full team strength, even in extreme terrain. In addition to sufficient head- and legroom, there is also plenty of stowage space under the fold-down rear bench seat. Tools, equipment and personal belongings can be safely stowed in them and are always at hand. The front-door compartments feature further stowage options. A total of four wide-opening doors - two on each side of the vehicle - also provide ergonomic access to, and exit from, the rear passenger compartment.
