Mercedes sold over twelve-thousand diesel-powered vehicles in the US last year, but a crankshaft issue is sending 9,004 units back to the dealer for repair. NHTSA says the problem lies in a crankshaft sensor that can fail, which causes the engine to lose power and makes you the "disabled vehicle" the traffic reporter on the radio warns your fellow commuters about. That won't do. The recall affects 2007 E320 Bluetec, ML320 CDI, and GL320 CDI models. Since the sensor defect could leave drivers stranded, we're going to go ahead and recommend that you get this one fixed right away. We're still bullish on diesel, however, because high fuel economy and gobs of torque are a wonderful combo.

Looks like Mercedes-Benz is expecting diesels to make a huge comeback in the United States over the next few years. M-B is apparently projecting that diesels will account for a whopping 10 percent of U.S. sales by 2010, up from just 3 percent last year. With the new BLUETEC-nology helping the German automakers meet stricter Bin 5 clean air standards, and gas prices continuing to hover near the $3/gallon level, it's likely diesels will become more attractive to buyers, especially in the light- and heavy-duty truck segment where the mileage and torque gains seem huge compared to gas-engined options.

New low-sulfur diesel fuel is finally becoming more widely available in States too, so look for diesels to start popping up everywhere soon. Mercedes in particular has shown off the possibilities of diesel in its E320 and will start selling diesels this fall starting in the ML320 and then the GL320 and probably the R320, as well. And Mercedes isn't the only company expecting big diesel gains. J.D. Power's Global Outlook for Diesel predicts North American diesel sales to account for 15 percent of new vehicle sales by 2015.

UPDATE: Our man Sam from AutoblogGreen was kind enough to inform us that these new Benz's are on sale now, however, are only available in 45 states. The E320 is the only vehicle that will come equipped with BLUETEC and urea injection currently, while the others are utilizing a common rail setup. All will come equipped with BLUETEC and urea by 2008.

Hot on the heels of the widespread adoption of new diesel throughout the U.S. last week, Mercedes has announced the impending arrival of three BLUETEC equipped models.

The ML320 CDI SUV, the R320 CDI, tarted-up minivan and the E320 BLUETEC will all come equipped with a three-liter V6 diesel that will make upwards of 200 HP and close to 400 lb.-ft. of torque. Mercedes contends that these new diesels will provide the pull of a V8, yet return mileage numbers comparable to a four-cylinder.

The E320 BLUETEC sedan will chug happily along for over 700 miles before it needs more go juice, returning 40 percent better fuel economy when matched up against a comparably equipped E-series. The ML320 CDI increases its fuel mileage by 28 percent and the R-class will get a 32 percent bump in fuel economy.

These new engines claim to meet the world's most stringent emissions standards and should begin arriving on U.S. shores soon.
