A good idea that does not translate to real life well. SX engines are more complex to manufacture and are difficult to maintain at the dealership. At a time when efficiency combined with cost-cutting need to merge, SX engines fail the test.
Mazda does make fine autos though ...
I had a Mazda GLC in the early ‘80s when I was in college. It was the cheapest and worst put-together car I ever owned.
Maybe it doesn’t like ethanol. Americans are in luv with their ethanol. Yuck!
The Mazda HCCI engine was probably squashed by a consortium of spark plug manufacturers, led by Bosch, who saw a threat to their bread and butter. </sarcasm>
What you did there...I see it. 🧐
I was very interested in the concept...but it did not happen in USA...”
Same here. Skyactive-X is the term for the new technology. As I understand it, they were looking for the best of diesel and internal combustion engine (ICE) technology. Sort of a diesel/ICE hybrid. It seems they were never able to pull it off satisfactorily. Besides, Democrats are hell-bent on getting rid of so-called fossil fuels.
I have no objection to CO2 as it is plant food that is necessary for life on earth. I don’t think it causes global warming or climate change. However, a warming of the oceans would cause a release of CO2 into the atmosphere.
I have no objection to advancing automotive technology. Reducing fuel consumption is fine when it makes sense. I think the hybrid idea of breaking by turning a dynamo to make electricity makes some sense, to the extent that it is feasible.
An “all electric” car gets its electricity from somewhere else, perhaps coal, perhaps nuclear. So, it is really a sham for the most part. However, an all-electric car might make sense for a city that has a smog problem. It would move the smoke someplace else where there are fewer people.
Neighbor has a Mazda with that Skyactive engine in it. Raves about the fuel economy. It’s actually a nice looking and well appointed vehicle too.
Correction:
“I think the hybrid idea of breaking”
I meant braking.
There probably aren’t many of us left who remember the Mazda Wankel engine: “Piston engine goes pop-pop-pop-pop pop but the Mazda goes Prrrrrrrrr.” It had reliability and fuel economy issues but was finally killed because it couldn’t meet increasingly stringent emission standards. This one seems to have issues, as well. It’s complicated and likely heavy due to all the extra parts. Roots blowers are inherently heavy and inefficient.
This guy got one in to tear down and see where it failed. He couldn’t really tell exactly why it failed but generally, he likes this engine.
Dude knows his stuff and has an interesting channel. He tears down blown and broke engines:

Their cars are being sold here in the USA with that skyactive wording on the trunk deck area. My friend’s hatchback definitely says that on the back and he is in the lower midwest.
“I miss my RX-7”
Same, Ferris. Same.
Had 2 83s and an 86.
Paid $6300 for the 86. Much less for the GSL and the Limited.
Now, you couldn’t touch a decent running sports car for twice that.
Paging Doc Brown. I’d like to go back to 85 ……

No.
A gasoline engine compresses at a ratio of 8:1 to 12:1, while a diesel engine compresses at a ratio of 14:1 to as high as 25:1..................
Remember the rotary engine. I had one that blew up at about 25,000 miles.
I owned one Mazda in my life & it really was a wonderful car. It was the last of the Japanese built Mazda sedans, a 1988(as I recall) MX-6. There was one exception to it’s goodness,the automatic transmission...which I found out later was a problematic issue. Anyway, even that lasted quite awhile until it completely failed & I had to replace that part at some expense. While it worked though, it worked well. Comfort, handling, power & economy; it had it all. If it had a different transmission it could have been the greatest small car I’d ever own. I wish I had it back, but with a different transmission.
It was Wankeled.
Since making cast iron engines requires foundries and lots of energy to melt the iron and steel, these will eventually be abandoned. America will have lost its one true power, it’s industrial base. We will be defenseless...........................
Like the Wankel engine? “Piston engine goes ping, ping, ping, but the Mazda goes Hm-m-m-m-.”
I watch some dude on yooztube that put 4, 5, and 6 cores of these engines together. Talk about screaming horsepower!
Definitely not your grandpa’s shade tree.
