RX-9 Rotary Engine Puzzle: Confirmed?

Mazda hasn’t done anything to squash the rotary engine rumors flying around the possible new RX-9. In fact,  as of a few days ago,  an executive from Mazda confirmed in more or less words: Yes we are working on it, and it is moving along to a more advanced stage.

Let’s review what we have seen so far.

Hybrid Drive Train Patent dated September 2016

Mazda basically penned out a drivetrain setup for the next generation of Rotary vehicle. There was also a rotary specific i-stop type patent entered as well. The only problem is we have seen something contrary to this in the next topic which makes this puzzle interesting.

Rotary Turbo Patent dated August 2015

This patent got everyone (including myself) really excited. Top exhaust ports, a turbo mounted to the top, rear wheel drive, and it is screaming for a huge upgraded turbo to be sticking out of the hood….

One can dream right? I digress with that path but looking at this patent Mazda was working on a different variant of the engine and thought it was important enough to file a patent on it. It should be noted once again this patent was from 2014.

Dorr Support Structure January 2017

The last patent popped up recently and it suggests a lower slung sports car as it moves the door up at a 15% angle and uses a torsion rod to hold it open. The only use a car would have for this is if it is low and you don’t want to hit your doors on curbs when you open them.

Looking back further we can see other patents from Mazda which point towards the continued research of the next rotary with laser ignition, different configurations of the engine, the 16x, etc.

Recently at the Mazda tech forum in Germany, Mitsuo Hitomi from Mazda confirmed that the development is in the advanced stage.

It looks like Mazda is willing to say they are still working on it, but not willing to say, “Yes you will have an Rx-whatever on this specific date.”

Adding to the fire, several Japanese magazines have been saying the Tokyo Auto Show will have the next car at it as well.

With more and more pieces to the puzzle being revealed, perhaps this will be the year we get to see the next RX. My money is on the strategy that it will be teased much like the RX-Evolve and the RX-Vision were, and we will get a real car and one heck of a surprise at the Tokyo Auto Show.

A guy can dream right?!

Turbo Kit in Development for 2014+ Mazda 3 & 2013+ Mazda 6

Since 2013 and the loss of the Mazdaspeed 3, Mazda has really left a lot to be desired as far as power goes for its line-up.

Don’t get me wrong, we love Mazda here at CorkSport; the interiors and exteriors are on point, they get great gas mileage, and are exciting to drive. We will always continue pushing and developing the platform that Mazda is kicking out, but let’s be real…we love power.

That brings us back to why I am writing this exciting blog… Sky-G is getting some TURBO LOVE.

©Car & Driver

I’ll admit, we thought long and hard about moving forward with such a large kit. We hoped, we wished, and we dreamed that Mazda would eventually wise up and kick out a GEN3 Mazdaspeed, and we got really excited when we heard about the CX-9 Turbocharged 2.5L engine. Unfortunately Mazda chose not to go down that path; once we found out about that, we decided it was time to pull the trigger on the GEN3 Mazda 3 & 6 Turbo Kit.

Moving forward on a project of this size was not a trivial decision. There were many aspects to consider:

  • Do we make a complete kit or just design and manufacturing difficult components?
  • What is the right power level to shoot for?
  • How will the engine and drivetrain hold up to the increased stress of forced induction?
  • How do we properly tune the engine?

These are all important aspects we had to consider.

Let me lay out some details and choices we made.

The most difficult and time intensive aspect of the kit is designing the physical components that will make up the kit… the entire kit. And yes, we decided that a 100% complete kit was the only way to make this a great setup, so that exactly what we intend to provide.

A complete kit needs to include everything from the air filter to the downpipe, and everything in-between. This includes the intake system, turbocharger, intercooler piping, intercooler, exhaust manifold, downpipe, and all the necessary silicone couplers, hardware, and wiring extensions.

This will be the most complete turbo kit you can purchase for the 2.5L SkyActiv-G powertrain.

Mazda-3-Turbo-Kit-CAD-Assembly

Right behind developing all the components for the kit comes the tuning. We are working with Versatune to develop the software to control the 2.5L Sky-G engine with forced induction. This portion of the project will be kicked into high gear in the near future once all functional prototypes are on our test car and strapped to the dyno.

Lastly, some thoughts to consider:

Will the engine take the added power?

How much will it hold till it pops?

Time will tell on those questions, but we do have some stuff in the works that will help. However, just spit-balling here, something around 280-300whp would be a lot of fun in the Mazda 3 and Mazda 6.

Stay tuned as this project evolves through testing and development in the coming months.

What are your thoughts on this new project? Questions?

Leave them in the comments section, we would love to hear from you.

I have only skimmed the surface of this project and I could easily write pages and pages if time allowed.

Could It Be True A New Diesel Mazda Is on the Way?

It has been a while since I touched on the subject of Mazda giving diesel a shot again in the United States. Back in 2012, it looked promising that we would be getting the Skyactiv diesel-powered vehicles like the rest of the planet. After working on the calibrations to meet the U.S. emission standards, Mazda discovered they could meet the emissions, but could not hit the power levels to give owners the driving experience Mazda is known for. Mazda wanted to hit the targets without the addition of urea injection to clean up emissions. They were squarely behind the diesels, even racing the Mazda 6 diesel in IMSA, 25 hours of Thunder Hill, and in prototypes. In the end, the diesels were abandoned, but the message was still there: Diesel models will be sold in North America, it just became a when.

The New RX Unveiled

Mazda announced their latest concept car, the new RX-VISION. The new car will feature a rotary engine.

Let’s talk rotary!!! It’s no big surprise to any Mazda enthusiast, or car enthusiast for that matter, that Mazda released the first full concept look at the new Mazda RX. If you’re anything like us at the CorkSport office, you were giddy with joy talking about all the things the car may or may not have. I can say personally I was like a kid on Christmas morning as I saw the silk piece of fabric come rolling off the sleek sexy body line of the new car. I was thrilled. So like any true enthusiast, I want to share my thoughts on what I think we will and will not see when it comes to a production model a few years down the road.

Mazda rotary dreams have come true. Mazda announced their latest concept car, the new RX-VISION.

Mazda unveiled their latest concept car, the new RX-VISION with a rotary engine.

Let me first start by making it clear that none of what I’m about to say is confirmed. It’s my personal opinion on the car and what I think we will see in a true production model. SO here we go.

The first things to go will be the wheels and tires along with the side view mirrors. I’d say right now, with much confidence, that none of that will show up on a production model for various DOT regulation purposes. On that note, I think the A-pillar will move forward a lot and the roof line will be raised. I just don’t think that nice low profile will actually hit the streets. I think it’ll be a much more person-friendly entry for the average guy (or gal). Next, I don’t think the turn signals will stay unless they either get larger or are very bright. Once again, I base this off the fact that in order for this car to be legal to sell in the U.S., it will have to pass all DOT and NHTSA standards and they have quite a few in regards to glass, lights, crash test ratings, and much more.

Now for what I think we will see. We were all pretty much told that it will get a rotary engine but no details about the engine itself were released. On that note, I think we can say with confidence it’ll be a rotary engine under the SKYACTIV nameplate. It will have to be much cleaner and more fuel efficient than the outgoing Renesis engine to meet current EPA standards. I personally think it will be a naturally aspirated 3 rotor. I come to this conclusion because it will need the third rotor to make power — that really long hood profile tells me they need the room for something. Also, I think it will rev out real nice, as they all do, and be mated to a nice 6 speed manual of some sort.

The new Mazda RX has been revealed!

Like I said, this is all educated guesses of what I think will happen, but there’re still tons of maybes and what ifs out there. I think we’ll see the car around late 2018 or early 2019, with a price tag in the mid 50k range. Regardless, I think Mazda will deliver a great car that will live up to its legend and I’ll definitely want to drive it.

If you build it, they will come.

Cheers,

Vincent

Mazda said WHAT about the Rotary in 2017? Also, the 2016 MX-5

With more and more information circulating about the new Rotary and MX-5 Miata, we’ve compiled everything you need to know about these two beauties.

Rotary 2017

Mazda has been pretty tight-lipped about the next Rotary. In fact, just a few months ago, we heard a few sources claim that the Rotary wasn’t in development at all, or at least was no longer being focused on. Well, hope has been renewed! This news is thrilling, and it honestly lines up perfectly with what we published back in August: What Mazda Said That Will Have You Saying, “Take My Money!”

Mazda-Auto-Adapt-for-2020-CorkSport-Mazdaspeed-RX7-Rx8

So what’s the excitement? Well, according to an article posted here, Mazda Kiyoshi Fijiwara (Managing Executive Officer) recently was referenced stating that they should be coming out with a new Rotary in 2017 at the Tokyo Motor show. Mazda is pretty big into anniversaries, and this just reaffirms our hunch they’ll use the 50-year anniversary of their first commercially available Rotary to release a new one. They did it with the 25th anniversary of the Miata MX-5, so why not the Rotary?

This is exciting news, and the best part is, they say it should have close to 300hp!

In case you can’t read Japanese, see the (slightly modified) Google Translation below:

Kiyoshi Fujiwara, the Mazda Managing Executive Officer, at the event in Spain was saying that the company is thought to publish a new car equipped with a rotary engine at the Tokyo Motor Show in 2017.

2017: It’s a memorable year. The world’s first commercially-available car equipped with a rotary engine “Cosmo Sports” appeared 50 years earlier. The name of the new car is unknown. As specs become realities, it is clear the “RX-7” engine should come near the order of 300hp.

 

2016 MX-5 Miata Only Gets 155hp

In other news, the engine is officially confirmed at 155hp and 148 ft/lbs of torque for the next generation MX-5. Though this might seem underwhelming, we still have high hopes. The three reasons for these hope are as follows:

 Reason 1:

2015 Miata: 2,619 lbs, divided by 167 hp = 15.68 lbs per Horsepower

2016 Miata: 2,200 (estimated) lbs, divided by 155hp = 14.19 lbs per Horsepower

It’s only an estimate, but the next Gen MX-5 would have to weigh over 2,400 lbs in order to have a worse power-to-weight ratio than the current model.

Reason 2:

Mazda knows more than ever that everyone wants a faster and higher horsepower car.  This knowledge, and the fact that they don’t currently produce, and have not announced, plans to introduce a single Mazdaspeed variant of any of their cars, gives us hope. You might think that makes no sense, but consider it: Doesn’t all their silence about the next Mazdaspeed seem strange? How can a company that has the most vehicles racing in the World on any given weekend NOT have a Mazdaspeed? Secrets.

Mazda has been parading around their Super20 Miata since 2012—a roughly 250 horsepower supercharged Miata that’s received incredible press and reviews. Of course, it isn’t available for public sale. So why does Mazda continue to tease us? Why produce these totally reachable cars that people want without actually producing them for sale? It could just be for publicity, but our bet is also that Mazda has secretly been working on the next Mazdaspeed, and it will be an Mx-5. If we’re right…. we would guess everyone will receive a good confirmation of the next Mazdaspeed MX-5 soon.

Reason 3:

The MX-5 is the pinnacle of Mazdas to modify. More people are modifying their Miata/MX-5 than probably all other Mazdas combined. What does this mean? Turbos, Intakes, Exhausts, Suspension, Bodykits, Lighting: There are so many mods!! Mazda knows people love to modify their cars. If they don’t do it themselves, they know their customers will, which is why we have a feeling that with a few small tweaks, we’ll have this next MX-5 purring and putting out an extra 20-40 horsepower in no time.
