Yes, the 16X explored many of those points, but the "16X" as a project name is done. "Sky-R" is the engine being referenced by Mazda, not "16X". The 16X proved quite a few things, but that specific design iteration won't make it to production. All the SkyActive tech progress rendered the 16X obsolete.

That doesn't mean that a 1.6L rotary is not going to happen, just that it won't be specifically the "16X" engine code iteration.

The "330cc" size increase is accurate for the 16X, after all 1.6L - 1.3L = 0.3L = ~300cc. (the Liter values are not precise, but rounded).

All magazine references to an engine downsize are currently unfounded. Mazda has never released a single piece of information about what a full sized rotary "Sky-R" would be sized at. The ONLY size reference from Mazda since the 16X was shelved was the 330cc range extender showned at the auto show about 24hrs after the CEO made the statement at the start of this thread. And that is obviously not something that you can extrapolate to a full sized engine. Even 2 of them is still only ~0.7L. 4 gets to ~1.4L (which might be rather fun!)

That's usually not a feeling, more like a thought. Such as, I think there is an echo in here. If you can feel an echo though good for you, never knew that was possible until now.

My feeling is that as long as Mazda's the only one pursuing the rotary, we'll always be behind the 8 ball and always have issues. One manufacturer doing ALL of the development isn't enough. Why hasn't any other manufacturer looked at the rotary recently? Do they ALL not believe in it? Mazda should reach out to other companies for help. They are playing the rotary development too close to the chest. We need some German engineering. Heck, if the americans got serious about the rotary they'd turn it into a powerhouse as that's what we're all about

If only I had a dollar for every time you have had to go over this,

We have a better chance of randomly being offered blow jobs from Kate Upton than we do of seeing a new model Sports Car with a rotary engine as its sole power plant.

So what your saying is we get a ******* from Kate upton to go with our new rx7? I'll take the first one before she gets tired

had to do a wtf double-take, the first read through I saw the name "Kane", not Kate

slowredrx7

Yes german engineering such as WANKLESUPERTEC. with the latest stratified charge technology.
Or how about ROTRONUAV.COM. with there liquid rotor cooling something mazda hasnt being able to do.

I did find a patent for new rotary combustion chamber design. .I will look again and put it up.
Seems not only mazda trying to advance rotary technology
Maybe some one could provide links to these sites.im hopeless

I wish WANKLESUPERTEC was in english

All it took was some simple googling to make this post laughable.

slowredrx7

I was just pointing out to TALAN7 that there are some german engineers working on the rotary.I know they are not automotive.The engines for the unmaned aircraft start at a hp rateing simalar to mazdas range extender,so it is related.

What would be laughable is after dcades of improve ing apex seals they were no longer required.EG a ceramic rotary-houseing ,rotors and plates all ceramic.Clearance between rotor and houseing would be 0.01mm instead of 1-2mm.The houseing surface textured to resist flowThe rotors have radii instead of sharp corners
A simple google search will find more imformation on this ceramic engine

I post this to share with other members that rotary engine development continues ,not just at mazda The company are real ,the engines are real the patents are real

Is this real?

Look at the date of that article, this is old news. Since then Mazda has recorded their best profit year ever. so don't count the rotary out yet.

I dont see why they cant just keep using the RX8 platform and just throw a Duratec37 in it and call it a day. It'll be alot easier to engineer than a whole car from the ground up.

Ive driven a 2013 mustang with that engine and it hauls that porky beast around no problem. It could haul an RX8 chassis with great haste indeed :-)

Yeah why would Mazda not put a heavy *** Ford V-6 engine in a production Mazda Sports Car? It makes so much sense to do that

Nathan Atkins

The all aluminum duratec is less than 100 pounds more than the iron aluminum sandwich that is the renesis. I'm just suggesting they extend their continued use of the duratec V6 beyond just the CX-9 and into the rx8, the torque and power will certainly make up for the whoop-de-doo weight gain.

Trust me I'm almost certain I'm a better driver than you and a 200 pound passenger adds a third of a second over a 40 second autocross. I think adding less than half that weight to the engine bay with a lower cg than a passenger is pretty negligible.

Mazda have the ability to engineer this solution properly in short time, all they have to do is convince people who are stubborn about letting go of the rotary to buy in, and people who always stayed away from the rotary will buy in.

And sure they'll have to throw in a facelift or something. I'd love to see the new design language on the rx8 proportions.

Show me data on the weight of a fully dressed 3.7L Cyclone. And it's not only just about that anyway, it's just that it is silly to think that Mazda would ever put a V-6 in a true sports car.

a v6 in an rx??????? i hope your trolling, unless its an isuzu v6 because of tq curve

Nathan Atkins

they dont have to keep calling it RX-8 if it'll make 5 members of the RX8club forum cry, they can name it something else. MX-9? Who cares?

There are plenty of very focused sports cars powered by roughly 300 horsepower 6-cylinder engines, currently and historically. The RX8 chassis is too good to go unused and I'd prefer to see it live on with a more marketable powertrain.

It's really not as ridiculous a proposition as you guys are making it out to be. Mazda already use this engine and as long as theyre paying the liscensing fees to Ford or whatever they have to do to use it in the CX-9 they might as well dust off their RX8 building equipment and put a sportscar out on the market again. Rotary or not.

Like I said the RX8 chassis is too go to let it go to waste.

Nathan Atkins

I cant find any "data sheet" with "official figures", i'll leave that burden of proof to you. But a quick internet search turned up:

fully dressed Renesis ~265 pounds
fully dressed Duratec V6 ~360 pounds

so about a hundred pounds hunkered down in the engine bay, la dee f---ing dah

Rx chassis is dead

paimon.soror

iTrader: (15)

You do realize that although material weight is ~100lbs ... its position, orientation, size, etc will all play a factor into the true impact of that 100lbs on the chassis right?

Comparing +100lbs driver weight and +100lbs engine weight is absurd when you factor in the moments of force on the chassis.



here we go playing engineer again.
