Beginning in autumn 2009, Mercedes-Benz will offer its trio of crossover models in Europe with its 'clean' V6 diesel engine featuring BlueTEC technology. Besides the GL 350 BlueTEC 4MATIC, European customers will have the ML 350 BlueTEC 4MATIC and R 350 BlueTEC 4MATIC models to choose from. Already available in the U.S., all three models are powered by a 3.0-liter V6 diesel producing 211HP at 3,000 rpm and 540Nm of peak torque from 1,600 to 3,400 rpm.
Mercedes-Benz developed the BlueTEC technology that focuses particularly on nitrogen oxides in order to reduce the emissions of diesel vehicles. The tech involves injecting a non-toxic aqueous carbamide solution called "AdBlueÓ" into the exhaust gas flow that then releases ammonia. In the downstream SCRcatalyst system the ammonia then converts up to 80 per cent of the nitrogen oxides into the harmless products nitrogen and water.
According to the German automaker, the GL350 BlueTEC 4MATIC, ML350 BlueTEC 4MATIC and R350 BlueTEC 4MATIC already fulfill the emissions limits of the EU 6 standard, which won't go into effect until 2014.
As for the BlueTEC models' combined fuel consumption, the ML-Class and R-Class variants both return an average of 8.7 lt/100km (27mpg US) while the larger and heavier GL-Class has been rated at 9.0lt / 100km (26.1mpg US).
