Mercedes-Benz Zetros: heavy-duty all-terrain truck and its versions
Mercedes-Benz Zetros — a heavy-duty all-terrain truck with all-wheel drive, produced since 2008. We review the versions, engines, and what to check when buying a used Zetros.
Zetros in brief
Zetros — a heavy-duty all-terrain truck designed to work in challenging off-road conditions. It has been produced since 2008 with all-wheel drive and is intended for rescue services, the military, expeditions, forestry, and construction and mining tasks.
In Lithuania, the Zetros is rarely encountered: it is mostly used by special services and the military, while private owners are usually individual enthusiasts and companies that need the highest possible off-road capability.
Versions — what sets them apart
Zetros is offered in 4x4 and 6x6 configurations, and in the name (e.g., 1833, 2733, 2743) the first digits indicate the approximate permissible weight, and the last ones — the power class. Depending on the model, it can be a tractor unit, a cab chassis, or a special-purpose vehicle.
The cab can be basic, multi-seater, or with additional protection. Military and rescue versions often feature additional modifications: a snorkel (air intake higher up), extra lights, a stronger bumper, and tool mounts.
Engines and transmissions
Zetros engines are Mercedes-Benz diesels, of various displacements and power outputs (roughly from 300 to 430 HP, depending on the version). They are designed for heavy-duty work and to operate in extreme conditions.
Gearboxes are manual or automated, designed for heavy-duty off-road work. Some versions may have a tyre pressure regulation system that allows you to adjust pressure while driving, improving traction on soft terrain.
What to check when buying a used Zetros
The most important thing is the condition of the frame, axles, and suspension: Zetros work in harsh conditions, so check for signs of corrosion, frame deformations, and damage off-road. Check the axle grease, stub axle integrity, and the operation of locking systems.
If the truck has a tyre pressure regulation system, it is complex, so check if it works and if there are no air leaks. Check the hours and service records.
If the Zetros was a military or service vehicle, make sure it has been de-commissioned and has valid registration documents. Also, check the documentation for the cab and additional equipment.
