Transmission. As versatile as you need it to be.

 

The fully synchronized electro-pneumatic Telligent® gearshift, with its eight forward gears and six reverse gears, stands out with its smooth running, long lifespan, and high efficiency. It is perfectly designed to support numerous types of operations.

The synchronized Electronic Quick Reverse (EQR) makes it easy to change directions quickly or to rock free when off-roading.

The special off-road gear group, with an additional eight forward and eight reverse gears, guarantees maximum traction in the lower 1 – 15 km/h speed range.

Automatic Shift: change gears easily.

Take the strain out of driving while operating implements or hauling heavy loads. With Automatic Shift, you can decide, at the touch of a button, to use either M (for manual) or A (for automatic) gear shifting.

Either way, without using the clutch. Even in automatic mode, you can intervene with the gearshift lever and change gears manually.

Mercedes-Benz engines – always ready for peak performance

 

The low maintenance four-cylinder engines from Mercedes-Benz are state-of-the-art in every aspect, and perfectly equipped to fulfill every demand.

Technical features include direct-injection and three-valve technology, a turbocharger and intercooler, a steep torque curve, constant output over a wide rpm range, and high power reserves.

The combustion-air intake is positioned on the cab roof, where dust levels are lowest.

Driving and working modes - engine regulation as needed.

Select the proper engine mode for the job at hand with the push of a button.

  • Driving mode benefits from the range of engine speeds for road trips.

  • Working mode ensures minimal rev speed deviations.

  • The outstanding off-road design can cope with any challenge, thanks to its state-of-the-art technology.

  • The Unimog is a vehicle and tool in one. A work machine for challenging jobs, expeditions, or disaster intervention.

  • Low-maintenance engines, steep torque curve, and large output reserves let you tackle the most difficult terrains with your Unimog – year after year.

A radiator system designed for highest demands.

The radiator system has been specially developed to cope with the high demands placed on the Unimog U 4000/U 5000.The intercooler and radiator, each with their own viscous fan, are fitted side by side, high above the ground. This greatly improves the cooling performance and minimizes the danger of fouling – for optimum functional safety when fording. You can rely on the Unimog to get you through even the most demanding off-road operations involving temperature fluctuations or extreme dust.
