Powertrain

Keeping you moving -
on any topography.

Engineered for the region’s ultra-challenging tasks. All components of the Zetros powertrain, including the powerful engines, are designed to withstand the Middle East’s tough conditions. From the gearboxes to the engine cooling system, everything is designed with performance in mind. However extreme the climatic conditions and however difficult the terrain, the Zetros won’t let you down.

Efficient and future-proof: 6-cylinder in-line engine 7.2l

The 6-cylinder in-line engine with a displacement of 7.2 litres offers 240 kW (326 hp) at 2200 rpm and 1300 Nm at 1200 - 1600 rpm. This engine is available in Euro 3 or Euro 5.

Its highly future-proof technology successfully meets every challenge posed by different industries.

This engine also helps cut costs – thanks to long oil-change intervals, wear-free components and low fuel consumption.

Taking the power to a new level: The new 12-liter, six-cylinder in-line engine.

The new power for the three axle version of the Zetros provides the 6-cylinder in-line engine OM 457 LA, which delivers up to 80 kW (100 hp) more than the OM 926 LA. With a displacement of 12.0 liters, this engine develops the maximum power of 315 kW (428 hp) and 2,100 Nm of torque – and takes the tractive power of the all-wheel-drive truck to a new level.

Thanks to more power and torque, the Zetros is ready for any conceivable application, with power to spare.

The Zetros cab: designed for efficient engine cooling.

The Zetros cab: designed for efficient engine cooling.

Unlike standard over-engine cab designs, the Zetros cab positioned behind the engine allows the airflow around the bonnet to disperse the heat and to cool the engine. This is crucial for working in the extreme heat of the Middle East.

Transfer Case

The 2-speed VG 1700 transfer offers one road ratio, one off-road ratio and a switchable centre differential lock. The case distributes the power of the drive shaft to the front and rear axle(s).

Permanent driving of the axles delivers the maximum possible propulsion. There is no loss of tractive power – unnecessary shift operations are eliminated.

The centre differential lock contributes a high level of driving stability by compensating differences in rotational speed of front- and rear-axle wheels on one side.

Transfer Case
The automatic 6-speed gearbox for the 326 hp engine.

The automatic 6-speed gearbox for the 326 hp engine.

The 6-speed Allison automatic gearbox is an electronically controlled gearbox variant. It consists of a hydrodynamic torque converter with lockup clutch and integrated torsional vibration damper, a downstream, multi-stage planetary gearbox, and an electrohydraulic control. It can be also ordered with hydrodynamic secondary retarder as an option.

The powertrain is protected thanks to gentle, smooth gear shifting as there is no clutch pedal, and the gears are changed automatically.

In addition, it helps keep drivers from getting stuck in soft ground due to wrong gear selection or clutch operation.

Manual gearbox for 6-cylinder in-line engine 7.2l and 12.0l.

The Zetros is equipped with a direct-drive gearbox with 9 forward gears for the 7.2l engine and 16 forwars gears for the 12.0l engine as well as one reverse gear in each case. It consists of a 4-speed basic gearbox with pneumatic rear-mounted range unit. Gear shifts are performed hydro-pneumatically. The result? Simple, secure shifting with no linkage in the cab.

Strong cast axles for high loads.

Strong cast axles for high loads.

The Zetros is equipped with robust, cast-steel planetary hub reduction axles with differential locks. They are designed for a technically possible load of 7.5 – 9.0 t on the front axle and 13 - 16 t on the rear axle. The 6x6 is equipped with a planetary hub reduction axle with through-drive and differential to the 3rd axle.
