Just read an article about how well done the new Miata is... not just hp/weight ratio, but fit/finish, design, materials, ergonomics. If they can scale that up, they might have something.

 

AAAAAHHHHHHHHHHHHHHH...I can't take this...I'm about to go squeeze the truth out of someone at Mazda...

 

I'm just glad they are finally bringing the Rx7 back. Wonder if it'll be the "FE"?

The RX-8 was the JM1FE1xxxxxxxxxxx model already.

Maybe the FF? Sounds cool.

I think a 2 rotor NA could be a good car with all the fixes to the 13B-MSP the newer DI generator motor showed.
If its a 16X with that overlap I think they should be able to get it over 350 at the crank with quite a bit more torque than a 13B NA.

Hopefully they get a dual clutch close ratio trans option in there to make each of those little horses count.

Perhaps the 2020 model will be the rotary super car you guys want.

Gas is cheap, the rotary is coming back-

 

Gordon based on Mazda's rotary history, I dont think anyone is ready for any rotary to cost that much until reliability is proven 1st. There's a bad taste in the mouths of many 1st gen Rx8 owners. Mazda (as a newly growing company) isn't ready to produce a product priced that high. They gotta start walking all over again before running.

 

I think Mazda knows very well that any new rotary MUST be reliable.

With the FD they were pushing the performance boundaries, so a less than stellar reliability could be expected. The Rx-8 was developed on too small of a budget IMHO, so not enough engine reliability testing went into the Renesis.

Mazda knows how to make a reliable rotary (think 1st and 2nd gen NA Rx-7). I really hope they take their time to do it properly, as they're starting from a clean sheet for the first time since the late '60s.

Andrea.

 

Well they've had all the time in the world recently so this new engine had better kick ***.

 

Put the new engine into a privateer racing frame and put it through its paces in competition.

 

I just hope it's true, please God, Oprah, Tom Cruise tell me it's true

 

 

LOL, I lost it at Tom Cruise.

 

they have done this since the 70's... even the 6 diesel cars have been racing for a few years.

 

It's the best way to torture test the engine, electronics, cooling, etc. and market rotary performance at the same time. Too bad their diesel efforts haven't paid off yet. I'm sure Mazda has learned a lot from taking it to the track, whether or not they win.

Also, it would be cool if the engine used direct injection and "lasers": http://www.photonics.com/Article.aspx?AID=51731

 

agreed! the 6 diesels are totally reliable, quiet and get good mileage.

 

I think unofficially naming this new car the FF would be super.

FF for Faster & Furiouser or Fast Forward.

FF is 255 in hexadecimals (which has 7 factors, not including itself).

 

how about a sequential 3 rotor, where the third rotor only starts after 4500 rp....


okay ill stop

 

why not take advantage of the rotary. it has 4 strokes in 4 different places, so why not tailor each place to each stroke? think about it. you could have BDC on the intake stroke be really big, so there is a little extra volume, TDC on the exhaust really small, so it has less room for gasses to hide out. etc

 

Lol while we are on theories . I was wondering last night ... The rotary is a little like a two stroke ( fixed inlet and outlet timing determine by the size and shape of the intake and outlet ports ) why did Mazda never implement a outlet valve like the two strokes have in the outlet port ? This way you could vary the size and shape of the outlet port depending on revs , or is that not feasible ?

 

On the two-stroke theme, curious how exhaust pipes with expansion chambers would interact with the rotary, especially with varying degrees of intake/exhaust port overlap.

 

So instead of brap, brap, brap,,,

It would go bing, bing , bing?

 

That article claims spark plug repairs cost 16k annually and are 100$ a piece...

 

They are bad at math but lasers are still awesome.

 

Haha,
New Miata disappoints everyone with 155 hp. Same old Mazda.
I wouldn't be looking for any 400 hp RX7 anytime soon.

 

The Miata was never suppose to be Mazda's hotrod. I own a 1st gen 95 Miata with the 1.8 that only has 131 hp. It's my beater and future Renesis swap candidate. Sure by comparision and extra 14hp isnt alot but the new engine is suppose to have alot more torque. Plus my Miata wont get anywhere near the mpg this new version will. Base numbers only tell part of the storey. I think people will be surprised by its performance when they actually drive it.

Edit.
New Miata 2300lbs and 155hp = 14.8 lbs per hp.
Fd Rx7 2,800lbs and 255hp = 10.9 lbs per hp.
Rx8 3,100lbs and 232 hp = 13.3lbs per hp.
Also from what I understand, Mazda is gonna be aggressive with many Mazdaspeed versions of numerious cars in the future.

Was the power figure for the 2.0 ND Miata released officially? I only saw 130 something hp for the smaller 1.5, and as far as I know that should be an official figure, but nothing for the 2.0 yet.
155hp from the 2.0 would seem very low when compared with 130+ from the 1.5

Yes 2.0 here in America.

This is just beginning folks. This car will see a power increase.

Here's the turbo info.

I know none of this has to do with a futrue Rx7 but at least it will give us an idea of Mazda's future direction as it relates to its new products.
