G this is good time to start saving : because the new Unimog U 5023 and Mercedes Zetros models, which are currently being used by the German armed forces, will of course be retired in a few years. Many expedition travelers can already dream of this, because the two trucks set the benchmark in terms of off-road capability in their segment.
The return of the hood
With the Zetros, Mercedes shaped the return to the “hood” among the highly off-road vehicles Commercial vehicles. The advantages of the concept are particularly noticeable in off-road operation: When it is not a question of maximizing the use of the traffic area, as is the case with regular goods transport on the road - the main reason for today's truck construction, in which the cab is placed on the engine and the front axle - The Hauber design only brings advantages.
Access to the engine is possible without a tilted cab, due to the seating position behind the front axle, the driving style and handling when driving off-road is similar to that of a normal off-road vehicle. Anyone who has ever looked into the abyss in a modern forward control off-road truck on or even sitting in front of the front axle in front of a steep descent will appreciate this very much.
With camera system and four-point belt
The GLF models of the Zetros also use the Hauber concept from a military point of view : Easier access and, in the event of danger, easier exiting of the cabin are a clear advantage over conventional designs. The Zetros GLF also has a corresponding armor in the cabin, newly developed seats with decoupled suspensions ensure driving safety even when driving rough terrain thanks to new integrated four-point belts.
In addition to the normal series standard, there is also a communication system and a camera system for the Integrated overview to the rear. One of the highlights of the Zetros GLF is the newly developed cabin concept. During peaceful operations, the armored cabin can be converted to a 'civilian', unarmored variant relatively easily within a day - this has corresponding advantages in terms of payload and fuel consumption when driving empty.
Mercedes Zetros also runs on poor diesel
The German Armed Forces saw the Zetros GLF as a two-axle vehicle with five tonsPayload put into service from the end of 2012. The 326 hp six-cylinder diesel can be driven in Euro III or Euro V versions, depending on the application, and should also cope with extremely poor fuel quality when used abroad. The drive is taken over by a six-speed Allison automatic transmission, which the transfer case with permanent all-wheel drive and reduction operated, axle locks are of course also included. The functional principle of the drive train is therefore similarly safe and convenient to use as in the Mercedes G. In 2014, a 430 hp machine with Euro 6 and 16-speed gear was added to the Mercedes range.
New Unimog U 5023
The Unimog U5000, which Mercedes supplies in the protected GLF version, is also used by the Bundeswehr. The 218 hp OM924 diesel can optionally be combined with an automated manual transmission. Permanent all-wheel drive, locks and ultra-short gear reduction bring the outstanding off-road capability familiar from the Unimog.
The successor that Mercedes showed at the Eurosatory trade fair in Paris is ready for future tasks. The new Unimog U 5032 went into production in summer 2014. The successor to the legendary U 5000 comes with the new BlueTec 6 engine, a four-cylinder now with 230 hp and a torque of 900 Nm. The Unimog transmission has been optimized and increased performance so that the shift times are now shorter while the service life is increased at the same time. As before, eight forward and six reverse gears are available, optionally also an off-road group for off-road use in the speed range between 2.5 and 35 km /h. The total weight is a maximum of 14.5 t.
The successor to the legendary U 5000 comes with the new high-torque BlueEfficiency Power BlueTec 6 engine, a four-cylinder now with 170 kW (230 hp) and a torque of 900 Nm in the Euro VI emission class. The Unimog transmission has been optimized and increased performance so that the shift times are now shorter while the service life is increased at the same time. As before, eight forward and six reverse gears are available, optionally also an off-road group for off-road use in the speed range between 2.5 and 35 km /h. The total weight is a maximum of 14.5 t.
Compared to its predecessor, the cab has been extended by 120 mm and slightly raised. The interior of the U 5023 features new features - multifunction steering wheel, adjustable steering column, steering column stalk, multifunction buttons. Due to the new mid-engine position, the frame offset is now further back, overall a lower vehicle center of gravity with high ground clearance, which among other things improves the driving characteristics in off-road use. The welded frame and tubular cross member guarantee extremely good torsion of up to 600 mm in the terrain. The axle articulation of up to 30 degrees does thatPush tube technology in connection with the coil springs is possible by connecting the axles to the gearbox via push tube and push ball. For really large transport tasks, Mercedes has also presented new 8x8 versions of the Arocs and Actros in Paris, which we are also showing you in the picture gallery.
