Even though spy shots signal that exterior adjustments on the next Mercedes-Benz GLK will be subtle, there's one giant adjustment coming under the hood, and it smells like oil – in a good way. Automotive News says the revamped softroader will gain a new diesel engine option. For its part, Mercedes-Benz hasn't said which of its oilburners it will offer with the GLK, but it's been hinted that it could be the 2.1-liter turbo diesel mill with 204 horsepower and 369 pound-feet of torque that sees duty in models like the C-Class and M-Class in other lands.

The addition of the GLK and next C-Class will make seven Mercedes model lines offered with diesel in the U.S. With the GLK's fuel economy addressed, the hope is that the entry-level crossover can find roughly 13,000 more buyers per year and close in on 40,000-sales-per-annum threshold. The brand already offers far more diesels than its German competitors here, but still wants to raise percentage of diesel sales from 12-to-20 percent to 15 to 20 percent.

      The GLK220 CDI is the most common model in Europe. Fuel efficient, good performance and the extra torque is also good for towing. There really is no need to go for another, more powerful model since 'performance SUVs' are an oxymoron. The GLK220 CDI would be my choice if I went for a GLK. A few days ago I actually saw a GLK350 and I was shocked. Those are so rare here.

        The GLK350 was the only Mercedes my wife drove that I could say I liked (all her others were C-230s).

          Was? Guess the milage got to you...its horrible! The now nearly outdated Suburban/Tahoe offer similar mileage. A diesel should have been offered from the beginning.

      I always thought this was an ugly crossover when it came out and my opinion hasn't changed just because it is getting a diesel option. Too bad other carmakers like BMW don't bring a small diesel to the X3.

      FINALLY! The GLK's one demerit this whole time was pitiful fuel economy: 16/21 is horrible for a small crossover. With the diesel they finally have a strong competitor in this class, and I can't wait to drive one!

      I've noticed this blog has cult of posters who call for everything to have a diesel option. What is so great about diesel engines? I was standing next to an idling Ram diesel truck and it was noisy as heck

        Are you seriously comparing a Cummins Dodge against a true modern, small displacement diesel? It is obvious you've never driven a modern diesel in your life. I suggest doing so, and not just for a quick spin around the block.

          Cummins Dodge is a wonderful, albeit large, modern engine and most people who drive it would probably be open to the small modern diesel you support. You should consider also encouraging people to test drive a Cummins if they have access to is. Or educate the people that enjoy the diesel experience in their HD truck that there is finally some modern small diesels in America. There are many, many more Americans that have driven a Cummins and loved it than driven your little passenger diesel at all. If you tell them these little diesels are not like their Cummins they will probably conclude that your little diesel sucks and stay far far away from it.

          Bingo! Besides that, the parent is saying he values noise over mpg?

          Well the Ram truck was practically brand new and very noisy. Diesel fuel isn't any cheaper that I have noticed and I do stop and go driving to work. I just don't see what the benefits are. Will the mileage really be that much better but at the expense of how much torque and power:

        And some of us cult of posters own a modern diesel - I have a '12 Golf TDI. I get wonderful mileage, I pay barely more per gallon than super unleaded, I have significantly more torque than most small cars and it's an absolute blast to drive. Try driving one before you bash it.

          I didn't bash it and I never said I wouldn't consider owning a diesel. I don't see many diesels on the road. Ironically enough I mentioned the noisy Ram diesel. Well on my lunch break today of all things a White Ram diesel was idling (noisily) next to me in traffic. From what I gather the diesel in say a new VW Jetta is not noisy at all?

        diesel truck engine <> post 2006 passenger car / suv diesel engines. Bottom line, it's still the best option for those that do more highway driving than stop and go city driving that would benefit hybrids more. So you've probably then noticed these same posters wondering where the diesel hybrids are....

        Consistent 300,000 to 500,000 mile service life with regular maintenance More energy per gallon of fuel Decent horsepower and unglodly amounts of torque (i.e. acceleration) Some people make their own fuel at home Renewable fuel You can drive 600-700 miles on a tank of fuel in sedans The budget minded consumer, of which most folks on the Internet are, wants the best value for their money spent. You might consider a diesel vehicle if it lasted at least two times longer than a conventional vehicle.

          Well, you really can't run homebrew biodiesel in the modern cars. Current users are getting away with as high as 20% (B20) but any higher % and oil dilution becomes an issue. Also, modern Common Rail diesels see temperatures at the injectors that cause bioD to become a problem (varnishing and other issues). We need a 2nd generation of biofuels to get around these issues.

      THANK YOU MERCEDES for realizing the futility of a hybrid and the value of a diesel... I am so tired of automakers not providing a diesel option in America, so my hat is off to you, Mercedes, for AGAIN leading the way! BTW, I think the GLK is amazing looking!

        From reputable sources, you might just get what you wish for. Chances are about 80% that there will be a diesel F30 and seemingly 100% is that it will NOT be a 3.0 liter unit.

      they would sell more of these, if Mercedes would offer a two door version and offer a manual transmission

      My '01 ML-320 at 110,000mi gets a regular 20mpg .. much the same with my 217,000mi Ford Escape. Our Volvo V-70 wagon gets mid-20's as did the P-997 I sold a few months ago. I WANT an F'ing Diesel. I wish the hell KIA would bring one..or that new V-60 was coming here. I don't want to feed the criminal Ethanol lobby any longer. I'll wear rubber gloves and shoe covers if I have to. Bring it! Jim

        Good point, I think the TDI is very necessary in the Tiguan and should have been offered in it from the start
