Our EURO III, V and EEV engines are synonymous with strength, economy and durability. Based on these characteristics, our engines in all series are ideal for short radius distribution, construction site transport and long distance haulage. They can also be modified to create customer-specific variants for use in different truck applications. From the 4/6 cylinder in-line models to the V6/V8 engines, the EURO III, V and EEV engines represent superior function and efficiency. The EURO V engines operate at the highest levels of efficiency and ensure superior power output. Thanks to BlueTec®,

Mercedes-Benz's SCR diesel technology, they operate in a particularly eco-friendly way. BlueTec ensures low CO2 emissions and extremely low concentrations of nitrogen oxide (NOx) and particulates, to meet emission standards at the tailpipe. Besides low consumption, the BlueTec® engines also have impressive maintenance intervals and a long engine life. At Mercedes-Benz, we have spent decades bringing our diesel engines to perfection. Our dedication to excellence has earned Mercedes-Benz loyal customers around the world, in the most demanding industries.

Our engine product portfolio: TCO reduction at its best.

Retarder.Hydrodynamic retarder.

The integrated hydrodynamic oil retarder from Voith offer a high braking torque in combination with a compact, weight-saving design. The weight advantages of the new retarders are between 25 kg (VR 115) and 35 kg (VR 123) compared to previous oil retarders. The braking power of the retarder is also independent of selected gear or current engine speed. A gear change does not result in any interruption in the retarder braking action and the retarder braking power depends only on the current driving speed.

The braking power can be controlled precisely in five stages using the right hand control stalk on the steering column. In addition to the engine brake, the retarder provides a maximum braking torque up to 3500 Nm (VR 115 HV) or 1500 Nm (VR 123).

• Stainless steel heat exchanger

• Power loss reduction by axial rotor displacement

• Optimized hydrodynamics

• Integration into the vehicle management

• Standard prop shaft length is determined by the retarder unaffected
