I want 0-60 in 1second!

... development for this will take time, obviously mazda has been working really hard juss to pull off the current renesis... dun expect miracles to come out of RD. n still, the public perception of the rotary is more important than the performance... n gas mileage... who the **** cares bout that... but stupid fukin hybrid green **** would complain like crazy.

the public is everything.......thats capitalism

I, for one, am quite happy with the power of my 8. If I wanted something faster in a straight line, I would have bought it.

I'm sure they are doing the best they can to make the engine more fuel efficient, but outside of direct injection, what else could they do? With the rotary, better fuel efficiency is probably easier said than done. I don't even think direct injection will help that much.

refugeefrompistons

the public will never accept the rotary as it is, people wish it to be something that is nearly impossible. Do you really think mazda is that crappy that they just send out a product they noe can be easily improved (... maybe....). But Mazda will not be able to make the rotary much better without EXTREME compromise in either power output or reliability, .... etc (at least at its current stage of development and RD)

I think DI gives about 5%-15% gain in fuel economy for piston engines, don't know how it would relate to a rotary.

rotary crazy

they can do so many things, 3 sparks per rotor, DI, lightter rotors, more compresion,increase displacement, all aluminun engine, etc.

Why more compression? I thought we would want LESS compression that way we could get more out of a turbo using boost not to mention it would let us use lower octance fuel.

Hey folks. There is a really good SAE paper in MazdaManics SAE library that he's linked on this forum on DI rotary engines that tells exactly how much power and performance improvement you'll see. Look it up and read up. It's very interesting stuff.

No point in speculating when the information is out there eh? Read up and find out.

for NA aplication is better with more compression

This is what the latest WHEELS Mag out tomorrow says....

SPINNING UP DRIVETRAIN REVOLUTIONS

"Mazda drivetrain engineers are also beavering away, with both a new-generation rotary engine and a radical hydrogen-electric hybrid slated for production by 2010.

Mazda still believes passionately in the rotary engine, and has announced a new-generation variant will go into production around 2010. Cutting the rotary's petrol and oil consumption is Job One at Hiroshima, but improving power and torque - without turbocharging - and reducing emissions is also paramount.
We hear that revamping the current RENESIS 1.3 litre is not a straightforward task, so the next rotary will, in effect, be a clean-sheet design.
Mazda will also introduce an original hydrogen-hybrid system by the start of the next decade.
Mazda already manufactures a hydrogen rotary that is currently undergoing trials, but the next step is marrying a 3.0litre hydrogen rotary with an electric motor in one compact hybrid unit.
The most likely recipient of the hybrid would be a people-mover or CX-7 style SUV"...

A lot here we already know...thought you might be interested.....

this is really intresting, what could be the possibilities?

I think they are going larger

mtrevino

Beavering?!?! Some nouns shouldn't be used as verbs.

Cool article though, interesting to know they are starting with a clean sheet... I'm definitely looking forward to it.

A 3.0 L rotary, HOT DAMN

rotarygod

Don't count on a 3.0L rotary.

zoned

wouldnt a 3.0 L rotary be huge?

rotary crazy

5 rotor

shaunv74

I think they mis-read the article in post 1 that states the rotary will have the same power as a 3.0L engine. Crappy reporting on their part. I would give as much creedence to their comment on it being a clean sheet design based on that. *sigh*.

rotarygod

I have actually heard elsewhere from an unnamed but credible source that they are in fact working on a clean sheet design. The real question is what do they interpret as "clean sheet"?

Red Devil

Not having the Renesis housings be stamped with a "13B"???

It'll be interesting to see their design innovations if not inhibited by the previous/current architecture.

Floyd

Check out this new take on a rotary design here.

RX8PDX

I have been looking at that for over 2 years now. I like the idea of post detonation.

Would be nice to see a new improved rotary, I hope it bolts into my 8, since I plan to still have it by 2010.

ASH8

IMO its obvious that Mazda cant go any further with the RENESIS running only on gas, because of emissions, I said this many times before.

I think the 3.0 litre is referring to an equivalent power (same power as)..think of it,, the engine would be 2.5 times larger that the present one, plus all the hydro add ons, and then ALL the electric crap...it would be huge.

15B or 16B...more like it.

I still have my doubts Mazda can "invent" a gasoline only Rotary that is emissions compliant past 2010....unless DI can be perfected...plus
Mazda has to reduce CO by about 50% to meet new Euro Regs past 2010.
Can't be done IMO....

Interesting times ahead though, I think RX-8 collectors will have an "in demand" car in 10 or more years time...the last of the rotary engines as we know them.

murix

I suspect they are rating the 13b as a 2.6l as is common. This means a 3.0l rotary to them is a 1.5l rotary to us, which has been on the rumour mill for as long as I can remember. Would be cool if they can do it.
