Looks like Mazda is still working hard to improve our Rotary engine. This also probably means that we'll see a new RX in 2010. I'm glad Mazda's sticking to its roots.

 

hmmm.........interesting!!!!!!!!

 

woOt! sweet. put it in the kabura!

 

I want a new RX8 in 2010 with more power and hydrogen fuel.
Then when I pass Prius drivers I can fire them the single digit salute.

 

pffft, why wait until then?

 

3 more years!!!

Who says I'm waiting? The hydrogen power will just sooth my concience

 

That's all it's going to sooth, because your hyrdo powered car is going to have almost no power.

 

btw, anyone see the irony in the hp numbers for the new engine? they are saying 20% increased power.. so if the standard renesis makes 190 whp, that finally gives us something close to 230 whp

 

The standard Renesis makes 190 whp? That's news to me.

 

seems to be between 170 - 190 whp.

I'll take the 20% increase in HP if it includes 20% better gas mileage.

 

It's not the current hydrogen powered engine...

Further ahead, Mazda also has an all-new hydrogen rotary engine with power equivalent to a 3.0-liter gasoline engine and a range of some 250 miles under development.

 

interesting...

however by that time I will be rolling in either the new V8 M3, or a Nissan GT-R.

Would be interesting to see what mazda does to get 20% more power out of the rotary (assuming) without turbocharging or supercharging.

 

Maybe Mazda paid off the tree-huggers to get 20% more power. If it wasn't for emissions, I'll bet they could get 300hp from the renesis.

 

Sorry guys, but the rotary is Dead...

The RX-7 FD was a legend, Thinking that the RX-8 would be better then the RX-7 I was in for a real disappointment. I know that Mazda has done everything they could with this motor. But, emissons will get more and more strict each year.

 

^^I kind of feel the same way, but I'm still holding out hope that there will be some breakthrough in development or research by the folks at mazda.

 

Do a search here on ceramic rotary engine

 

there are a lot of things mazda can do with the rotary engine, they could have done it to the renesis but remember how the renesis was develop

now is a diferent ball game, mazda has a lot of money to develop the rotary engine, it is the firts time since the early 90's that mazda is oficially developing the rotary engine

and the anauncement sais a new rotary engine, that does not mean that they can keep improving the renesis

I dont thing they will use ceramic, but some improvement in the metals they are using for the rotary have to be made if the rotary is to be competitive with the piston

 

That has gotta be more power in the current renesis as you pointed out. Excess unburn fuel will still be spilt outta the exhaust port, even being a side exhaust.

The next generation rotary has gotta have direct injection, it'll allow for better burning and less unburn fuel will make it outta the exhaust. IMO DI will give the rotary a little more power but greatly improve the emissions, which is holding back even more power. Do they even need 2 sparkplugs per rotor with direct injection? maybe? how about using 3 spark plugs? it gave the 787B a few % increase in fuel economy. How about 2 direct injection injectors with 2 spark plugs per rotor?

I think the new rotary will still be zero overlap, as RG stated, the improvement on horsepower came from that, compared to old NA rotaries.

Can they make a peripheral port rotary with zero overlap?

Or are they going to re-introduce a PP rotary if they solve the "fuel going out the exhaust port" issue. Fast forward 3 years from now!

it's good speculation, but i'll believe it when i see it... not to be a pessimist, but those figures are hardly worth getting excited over...

15 to 25% performance increase w/ a 20% increase in mpg? if the glass is half full, then that's only 195.5 whp (up from 170) and 20.4mpg (up from 17).

are u freaking kidding me? that's barely competitive even for right now, much less in 2009. in 2009, the german & other japanese makers will be doing much, much better than that. i hope those numbers are totally wrong, or they find a way to cut the weight of the car in half. otherwise, we're all screwed.

 

If they make the car weigh less than 2900 pounds, then that will be enough power.

 

I think the # we have to work with are 232hp so 20% would be 280hp

lets hope that 280hp is close to 230 rwhp

another thing is that they said a new rotary engine for 2010 but that does not mean they cant improve the renesis, even with DI

 

Well if my memory serves me right, I remember seeing some of the less fortunate 8s posting dynos in the 160 range, which was almost a 30% loss to the wheels. So 195.5 whp for this next rotary is still a possibility, worst case scenario.

But I think this speculation is pretty pointless. If you are still chasing numbers at this point in time after 4 years of owning an 8, you probably won't be buying another rotary anyway.

 

If Mazda takes a real technological leap it could be cool.
Think ceramic engine with direct injection, no cooling system, more power, better mileage and much lower emissions.
