Today Mercedes unveiled in Stuttgart-Unter¬türk¬heim a brand new generation of Mercedes-Benz medium-duty engines with the series designation OM 93x.

With these new engines and the heavy-duty OM 470 engine, Daimler is expanding its “BlueEfficiency Power” engine portfolio, complying with the impending Euro VI emissions standard. The OM 471 was initially presented in 2011 and it’s already in service on long-haul operations in the new Mercedes-Benz Actros.

“The new engines set new benchmarks in their class. They have been designed in uncompromising manner for environmental friendliness, economy and performance,” noted Georg Weiberg, Head of Truck Product Engineering Daimler Trucks, at the presentation of the engines.

Euro VI will be mandatory in the EU from 2013/14 and so Mercedes is once again assuming the pioneering role in environmental protection. The new engines are extremely economical due to low consumption of fuel, long service lives, AdBlue and engine oil, long maintenance intervals, all these assuring the OM 93x series spontaneous acceleration and impressive power delivery.

“We have invested around 500 million euros in development of the new Mercedes-Benz OM 934 and OM 936 engines and their production facilities at the Mannheim plant,” observes Stefan Buchner, Head of Global Powertrain, Procurement and Manufacturing Engineering Daimler Trucks.

The heavy-duty OM 470 engine with six cylinders and a displacement of 10.7 litres spans the power range from 240 kW (326 hp) to 315 kW (428 hp). It follows the OM 471 with a displacement of 12.8 litres which was presented last year.
