Exciting new rotary patent from Mazda
This is a pretty exciting patent just filed recently by Mazda . Looks to me like a small peripheral port (item 14) used to supply EGR to inlet plus it may also be acting as a wastegate for the turbo which not only allows strong twinscroll pulses from the main side exhaust ports for spoolup , but also allows some exhaust overlap to clear out the last of the exhaust gases.

Coming soon, the 2025 RX9 Vision!

So looks like the RE department is somewhat active.
Just hope the shoebox is worked out at this point as well.

"Die hards" don't pay for the R&D bills, unfortunately. It has always been like this. See S2000, Viper and RX-7/RX-8 for examples.
IMO this is just a small piece of the big emission and power puzzle. To get more pieces, they will need a high-volume car(the RE range extender) to bring in more profit to continue the R&D needed for a rotary halo sports car.
I can at least see that the side exhaust port that's move to the opposite of the intake ports to be useful even in an NA application - it looks like it can reduce the leakage from the intake port that goes directly to the exhaust port.

Never say never, right?
I would love to believe they'd be able to make another RX, but after the 2017 Vision fiasco, call me dubious.
I'm no expert, but as long as the rotary depends on oil injection in the combustion chamber for lubrication, I don't know how they'll make them meet the newer stringent emission standards.
I do appreciate you and Ash & others keeping us updated on the latest developments.
Thanks for that.

When I saw this I thought they might have borrowed the patent you applied from Brettus,
It certainly isn't getting any less complicated,
more ports,
more pipes,
more sensors,
more errors....

Cars are getting more and more complex in general so there is nothing new here.

Even this new motor design is remarkably simple compared to current piston engines if you really think about it. Still exponentially less moving parts, bearings, etc. and build quality along with component quality will dramatically effect overall quality and reliability.
I mean why do you think Kia cars 20 years ago had such a bad rap?

Simplicity isn't the only contributing factor to reliability. Compare the Renesis to any MZR/Duratec motor. One has few moving parts, ***** the bed early. The other had many moving parts and runs for damned near ever.

While we’re spitballing, I do find this interesting. Perhaps hopeful for what could come of it all in the next 10 years, as others have pointed out. Maybe an advancement towards a more efficient rotary for use in a high-volume car could lead to higher performance “zoom” cars. An actual rx9...not some clay concept.

Bring it on. I am sure there enough enthusiasts out there for this to be a good
seller. They will need to convince people they have learnt their lessons from the 8 - lubrication, cooling, spark! Also, i am guessing meeting the emissions requirements while ensuring those precious parts get the right amount of lube in the right spots may be the big challenge.

And I mean, when you have a good array of sports cars that don't require fussy maintenance, a rotary just won't be that attractive. You can make it some kind of supercar and get away with frequent service and complicated procedures, but I don't think Mazda can really pull that off.

The Sky-G with a turbocharger or small TVS supercharger is fantastic! I don't see much benefit to introducing a rotary again, at least not now. Sports cars are the devil at the moment and a company like Mazda can't take chances on a small market that they already offer a car for with the Miata. Our best hope is that that Miata lives a long life, weathers the SUV storm, and that on the other side of the rainbow, people begin loving sports cars again and Mazda can justify not only improving the Miata more, but introducing a rotary engine car for idiots like us.
