A new report from German publication Auto Motor und Sport says that Mercedes-Benz will be expanding its diesel lineup in the U.S., by adding tubodiesel engine options to its M-Class, GL-Class, and R-Class offerings.

All three vehicles will run a Mercedes 3.0-liter V-6 turbodiesel, capable of 210 horsepower and 398 pound-feet of torque, in an effort to burnish the image of M-B diesels among American consumers. New exhaust filtering technology will allow the oil-burners to pass emissions standards in California, as well as Euro 6 regulations.

Even the very heaviest of the new models, the massive GL320 CDI SUV (pictured above), is said to return a respectable economy figure of nearly 25 mpg.
