The Unimog is the smaller brother of the Zetros and is offered in a wide range of versions with different engines and wheelbases. There are two Unimog families available the Unimog 300 - 500 and the Unimog 3000- 5000.

Design

The Mercedes Benz Unimog 300- 500 models feature a robust design which copes great with their utilitarian character. Everything at this truck is part of the heavy duty league and its build quality is nothing short of excellent.

To cope with a wide range of harsh applications, the Unimog 300-500 models feature portal axles, permanent all-wheel drive, differential locks, extreme axle articulation and reduction gears for off-road being able to conquer any terrains without too much fuss.

The truck sits on massive off road wheels which are a solid proof of its strong abilities. The cabin is pretty tall and features a basic design that sacrifices form for functionality. At the front we find a symbolic Mercedes grille with the company’s logo mounted in its center. The grille is flanked by two thin turn indicators while the main headlights are mounted lower.

The practical exterior design of the Unimog offers three attachment areas. Firstly the front attachment area features a useful front mounting plate that can be used for verge cutters, snowploughs, snow cutters, winches and front-mounted sweepers. Secondly there is the inter-axle attachment area for road sweepers or graders, while the third attachment area can be found at the rear and is usually used for smaller rear-mounted cranes or sewer cleaners.

Interior

It’s clear that this vehicle wasn’t built for comfort, so don’t expect to a comfortable cabin. Though, some common sense features can be found inside and the Unimog’s cab can be considered a satisfactory working place.

Every element found inside puts practicality on the first place and you’ll find the Unimog’s dash pretty ergonomically designed. Needless to say that all the plastics seem ready to last a lifetime without breaking and the build quality is pretty close to a tank. In fact the Unimogs are frequently used in military operations, and there is no wonder why, given the “bullet proof” build quality of the truck.

Despite its spartan nature, the cabin is fitted with a very capable air-conditioning, heating and ventilating system which makes sure that the temperature is always kept in check. There is also available an optional Radio and CD-Player combination with Bluetooth and hands-free kit.

Moreover, the cab is made of non-corroding, noise- and heat-insulating high-tech fibre composite material. Apart from this, most of the vehicle functions are electrically controlled, so vibrations in the cab are reduced to a minimum.

The seats are surprisingly comfortable and you also have plenty of head room, but the legroom is a bit limited. There is also an optional air suspended driver seat which offers increased level of comfort and a more relaxing ride.

You won’t complain about the instrument panel either, as it’s fitted with a backlit instrument panel and two LCD multifunction displays which are easy to read in any condition.

The central console is a bit cluttered, but it has all the controls needed for keeping the various vehicle functions in check. Fortunately, every control is within easy reach and the layout is easy to understand.
