Wow, and we have been talking gloom and doom about TDI tech.
If Mazda sells a TDI now, VW will never withdraw TDI products from the U.S. market.
Yippee!!!!!!!!!!!!!!!!!!!

Interesting....after reading Mazda's explanation of their Skyactiv-D engine, it seems so relatively straightforward that it's surprising that none of the Euros have implemented anything similar. If Mazda's low compression design performs as advertised (and without SCR systems, etc.) that may breathe new life into the small engine diesel.

It would seem to me, that with a low compression ratio, it would be necessary at very low engine loads to have some glow plug activation to "keep the fire going".

I'd like to see all the Japanese auto manufacturers offer diesel engines in their cars sold in the US. Would also love to see VWAG's VW, Audi, and Porsche continue offering TDIs as well as BMW and MB.
Perhaps a new administration will put the brakes on the power mad bicycle and metro bus and train riders of EPA and allow us to buy diesels once again.
Electric go carts are not the answer. No one but city dwellers would buy them if not for the generous taxpayer subsidies paid to buyers of battery cars.

Wow - depending upon price and performance, I may sign my offer letter and make the change to the CX-5 Diesel.

Pretty sure the Mazda diesels here (if they do materialize) will have SCR. They initially thought they could manage without it because somehow VW could. Well....we know how that worked out.

Plus on east coast electric cars cause more pollution than diesel and gas cars. It is just Elon Musk paying all the congressmen to get money from the government.

Yes, special glow plugs appear to have something to do with it, and they also talk on that web site about the valve timing....there's some sophistication to it.

After having my 2015 Mazda 6 gasser, I really trust what Mazda is doing in their post-Ford era. The car was remarkable for the money, and I would trust it long term. It's a shame I sold it to "invest" in some TDIs, but I'm in a better place for it.
YES! Though I'd rather have it in my FJ while keeping my manual transmission...

It's coming next year, blah, blah, blah. How many years has the Skyactiv-D been predicted after an auto show? 10? Sure.

Its like the Peanuts cartoon, where Lucy always pulls away the football, just as Charlie Brown commits to kick it.

Or it's like the Golf Alltrack TDI - they tease us for 10+ years on it, finally commit to it, and then dieselgate...

"Hidden Costs of Energy"

Here is another thought. Look at the complete life-cycle impact of an engine technology on the environment. This is a more holistic and more accurate/realistic approach in my view:

GREET provides total and urban emissions for both WTW and vehicle manufacturing. Thus, urban and rural damages can be calculated individually (rural emissions calculated by subtracting the urban emissions from the total emissions), and a "composite" damage derived from combining the urban and rural damages.
Using that methodology, here is a graphic of the results I get:
This shows EV in a better light, especially if it's a very clean grid like California (virtually no coal generation), since a higher percentage of emissions are generated in rural locations.
Edit: The "Diesel @X5" uses the average overall "real world" exhaust emission profile of the BMW X5 35d measured by WVU in the ICCT report.
