Japanese automakers haven't lead the charge towards diesel power in the same way as, say, the Germans have. But Mazda is out to change that. It has been following Audi's lead on the racetrack with oil-burning racecars right here in America, and will soon translate that excitement to the road by introducing its Skyactiv-D engine in North America. It just won't happen as soon as we expected.

Mazda announced today that, while its diesel engine meets current emissions requirements, the company has decided once again to push back an introduction originally slated to kick off in the Spring. According to the brief statement below, Mazda wants to take more time to find "the right balance between fuel economy and Mazda-appropriate driving performance."

In other words, the Zoom-Zoom brand apparently thinks its diesel engine doesn't deliver the zoom-zoom American drivers would expect, so we'll have to wait just a little bit longer. Details to follow closer to launch, whenever that will ultimately take place.

Mazda SKYACTIV-D Update

Mazda's SKYACTIV-D clean diesel program for North America is being further delayed from its Spring 2014 announced debut timing. While Mazda understands its SKYACTIV-D engine can meet emission regulation requirements, it was decided that further development is required to deliver the right balance between fuel economy and Mazda-appropriate driving performance. Further information on the program, including a timeline of launch for North America, technical specifications and fuel economy will be available at a later date, closer to launch.

      It is difficult to bring diesels to the U.S. as many brands are finding out. VW and Mercedes have invested huge amounts of time, money and energy to make it work and they both have their issues.

      I wonder if this is a 6-8 month delay, or more of a "next generation of the lineup delay? I have been holding off purchasing a new car until I was able to test drive a Mazda6 with the SkyActiv-D power train. I am not willing to wait much longer though. I still may end up in a Mazda6, but the proposition of a reasonably priced diesel powered mid-sized sedan without a "V", and a "W" on the grill was very appealing to me.

        The diesel will be much more expensive and what you will win torque you will lose in refinement. They still vibrate more and make unrefined noises. And they are very heavy which means the car is even more nose heavy. Not so sure it's worth it. Now a low pressure on the 2.5, now that you get my attention.

          The Skyactive D is not much heavier than its gasoline counterpart. You'd hard pressed to tell the difference in sound between it and a small gasoline DI turbo.

        Get the SkyActiv 6 today, as I did. It is still the best fuel efficient mid-sized sedan around. The diesel version will still go through teething problems even if it can be launched in the summer or fall.

      Instead of worrying about the performance, they should worry more about the price premium over the gasoline cars. The Chevy Cruze diesel rolled out amidst great expectations, only to sell a measly 500 a month (The Jetta TDI sells 5X to 6X as many). All because GM stupidly put a $3600 price premium on the diesel car. Keep the price premium under $2000 and the car will sell.

        Plus the gas price differences. Where I live it really doesn't make sense to buy a diesel over a vehicle that just requires regular unleaded. The price difference is huge and the MPG difference isn't sufficient. However, for a luxury vehicle that already requires premium it's a safer bet. I know there's more to it (and other parts of the country differ), but the numbers are pretty off-putting right now.

        Ttust me dont worry about the cruze and gm. there goal is 20000 for the year and then the cruze is gettin a refresh. Then ur gonna see the diff trim levels and manual if the demands there. vw owners already tradin in on the cruze. Gm was smart to start small. iron out any emissions or calibration or whatever so there ready once this new cruze hits production.

      Another disappointing delay. First, it was the emissions...now it's something else. A Mazda 6 with this diesel engine is exactly what I've been waiting for.

      folks would buy 150hp sky G, what makes you think folks wouldnt buy 150hp/+225 lb sky D, Mazda? its more like you guys havent worked out the oil level thingy yet.

      What we probably want is a more horsepower focused diesel..... that sacrifices mileage for "ZoomZoom". Or you can just keep it efficient and give us what we want..... Mileage. I see no point of taking away any mileage for "better driving experience" when we're buying a motor using a completely different kind of fuel just to get mileage....

        Honestly, it's probably one of those decisions like, "Do we give them 180hp and 40 mpg highway, or do we give them 170hp and 43 mpg?" It's not enough of a difference to matter, but I think they understand that big horsepower numbers sell in the US, and a big hp number with excellent fuel economy sells better.

          Torque is what puts the butts in the seats (pun intended). Diesel engines do not need to have tons of HP when all the spin is available at low RPM. I don't know if the average buyer would make the distinction, but AB readers know the difference.

          Considering that the most powerful 4cyl. engine Mazda has available in the US right now (other than the MS3) puts out 184hp, I don't think high HP figures are tops on their list of concerns. Especially considering that the other diesels they'd be competing with (VW & Chevy), both put out much less than even 170hp.

      Stop posting this corporate incompetence on ABG. There is nothing green about it. Mazda put their faith in the combustion engine. Let them die in silence.

        I don't care about GREEN except my own and I want to stop spending GREEN to protect the world's oil supply lines. Mazda, diesel, TDIs, et al do NOT accomplish this. Go electric. All the knee jerks who bang their chins at the mention of GREEN are just hurting themselves and me. We do have common causes.

        Screw green! It's like being politically correct. I wish I could afford a Hummer H1 with a gas engine and it's single diget fuel Econ numbers just to piss off the tree huggers and greenies! My daily actually rated at 38 mpg but I would still like the Hummer.

      Take your time Mazda, do it right and the people will come. Stinks that there is a delay, but if they think it won't meet the demands or expectations of an American consumer, they know better than we do.

      Translation: "We haven't figured out how to keep fuel from contaminating the oil sump, and it won't pass California emissions anyway". This engine has been a disaster in Australia from a reliability standpoint. I'm rooting hard for Mazda on this one, but it appears they may be in over their heads.

      PR form Mazda, let us cut the chase, mazda gasoline skyactiv engines are very good, but the skyactiv diesel have been a nightmare with reliability issues, in race and normal driving cars, but kudos to them fixing the problem before bring it to the north.

          ELG it is not about the oil issue, it about about diesel fuel enter oil sump, but at least your are honest that there was one issue you new of, unlike nightflight who is in denial.

          Fuel in the sump and oil rise is the same thing. How do you know there's diesel fuel geting into your oil? its high on the dipstick.
