In order to boost the image of its diesel range in the U.S. Mercedes-Benz will be adding three new models to its lineup in August, all of which are equipped with the latest in Bluetec-diesel technology. The new vehicles include the ML and GL-Class (pictured) SUVs and the R-Class luxury MPV.

All three models will feature a 3.0L V6 turbodiesel with 210hp and 540Nm of torque. Thanks to the latest in exhaust filtering technology, the new diesel lineup meets California’s strict Bin 5 emissions standards as well as the future Euro 6 regulations.

Bluetec is the name given to Mercedes’ diesel exhaust filtering system and combines ‘AdBlue’ urea-based filtering as well as a ‘DeNOx’ oxidizing catalytic converter and particulate filter to remove harmful nitrogen oxide.

The heaviest of the new models, the GL 320 CDI, returns a fuel consumption figure 24.75mpg (9.5L/100km) and can cover a range of 1,600 miles before the AdBlue supply needs to be topped up.
