Mercedes-Benz will made available its three crossover models in the European market beginning autumn this year and each will come with its clean V6 diesel powerplant equipped with BlueTEC Technology.
European buyers, besides the GL 350 BlueTEC 4MATIC, will also have the ML 350 BlueTEC 4MATIC and R 350 BlueTEC 4MATIC variants to choose from.
These three models are already being offered in the US and are driven by a 3.0-liter V6 diesel generating 211hp at 3,000rpm and 540Nm of top torque from 1,600 to 3,400rpm.
The specific focus of the BlueTEC Technology, which was developed by Mercedes-Benz, is on nitrogen oxides in order to cut down on emissions of diesel powerplants.
The system involves non-toxic aqueous carbamide solution designated as "AdBlue" into the exhause gas flow that then releases ammonia. Then, in the SCR catalyst system the ammonia converts up to 80 percent of the nitrogen oxides into nontoxic nitrogen and water.
The German carmaker claims that the GL350 BlueTEC 4MATIC, ML350 BlueTEC 4MATIC and R350 BlueTEC 4MATIC already meet the emissions requirements of the EU 6 standard, which will be put in place by 2014.
As for fuel efficiency, the ML-Class and R-Class versions both come with an average of 8.7 liters per 100 km (27mpg) although the bigger and heavier GL-Class comes with a 9.0 liter per 100 km (26.1mpg) rating.
