Read it here (http://www.cartoday.com/content/news/singlepage.asp?in=5017) .

I hope that picture isn't accurate... the colour and the mags make it one ugly car compared to the '8.

Yeah... 224kw!... If my conversion is ok, that's 300hp :D ...but with Mazda, unfortunatly, that's only 202 WHP:mad:


.... sorry, to tempting;)

that sure is a ugly piece o shit....
:P

Its an RX8 with the rear-door lines colored by an artist (or a 4 year old kid..)

That looks like a mazda6 head + rx8 tail.....hope the real rx7 wouldn't look like this.

looks like a cross between a 8, a 6, and a rsx! Whos the father?

Umm....wonder if that engine would bolt up to the RX-8 when it is released?

If it does that would be a awesome aftermarket for us RX-8 owners.

Hehehe 300hp RX-8 Zooom Zooom

Relax Gentlemen,
Those of you who followed the RX-8 since it was just a concept should remember that the concept model and the final 8 model look completely different. The current version looks 10x better than the concept. Even the RX-8 prototype they demo'ed at the Tokyo AutoShow was not even close to the our production model in terms of styling. (the prototype look far less agressive and looks very boring complete to the final version)

I'm pretty confident that Mazda will make sure that next RX-7 will be the prettiest RX-7 yet.

From article: "Power for the new RX-7 will come from a reworked version of the RX-8's compact 2,6-litre Renesis rotary engine. With wider rotor chambers and other detail changes to stiffen the block and enhance cooling, the rotary unit is being bumped up to around 3,2-litres and should also boast a higher redline for better performance. "


How did that article come up with 2.6L size for the Renesis Engine? Did they compute it as 2 Rotors x 1.3L = 2.6L?

If thats the case, we can extrapolate that the new RX-7 will have a 1.6L engine... is that correct?

The Renesis displacement IS 2.6L when moving.

If I was confused before...now its worse.

Please exlpain why there is a difference between an engine displacement while stopped & while in motion.

The manual specifies the Renesis as a 1.3L engine...0.6? Litres per rotor.

So how in hell they came up with 2.6L for the Renesis...that would be a friggin' 4 rotor wankel (0.6? L X 4)

:D

Journalist's magic!! they can make the stupidest statement sound serious (just like me)

as far as the reason it is classed as a 2.5-3.0l motor...

....Traditional swept volume measurements are confused when tackling rotary engines. A rotary engine has three chambers created by the gap between the rotor itself and the rotor housing, as opposed to a the chamber between the head and piston in a reciprocating engine. The motion of the rotor moves the chamber itself (with the mixture contained in the chamber) from the inlet port, compresses the mixture, moves the chamber in line with the spark plugs to ignite the mixture, then moves the mix to an exhaust port... there are three chambers doing this constantly. So it's a very different process to a traditional reciprocating engine. That said, in motorsport and as far as many government bodies are concerned, a rotary engine in displacement is consider to be the equivalent of a reciprocating engine of double the capacity. In this case, RX7s are generally consider to be the equivalent of a 2.6 litre piston motor. On a four stroke there's only one intake stroke for every two revolutions, so from a breathing standpoint, displacement is how much combustion chamber volume gets sucked in over two revolutions. for a rotary, with one intake stroke per revolution, that means measuring two combustion chambers per rotor, not one, like mazda says. each chamber in a 13b displaces 654cc, so by mazda's two-stroke method, a 13b is 1308cc.

i hope my cut and paste from the internet helps.

I see fit to point out "...is considered to be the equivalent..."

Doesn't quite cut it when we start fiddling around with standards....A Renesis will still be a 1.3L (1308cc) engine...for me at least.

According to the quote above, the Renesis is in fact a...[suspense]...3,924 cc (4 Litre) engine ??

654cc * 3 combustion chambers * 2 rotors = 3,924cc :eek:

or

654cc (per rotor housing) * 2 = 1,308cc

or....maybe I should shoot myself.

ahhhhhhhhhhhhhh.

The persons doing the "consideration" include the FIA - for racing purposes, a 13B engine is classed as a 2.6. The new RX-7's 15B or 16B would be classed as a 3.0 or 3.2 litre engine. Even the Engine of the Year committee (which awarded the Renesis 13B engine top honours) placed the 13B in the 2.5-3.0 category).

hopefully the rx7 hp stays and the cars look changes

Welcome, I just hope they bring the bloody car to SA. ;)

From the logic of that article we need to go out and double the displacements for all 2-stroke engines too. Stupid.

Looks kinda like a G35c and a Pontiac Grand AM...humm...kinda like it though. Looks more luxury coupe oriented IMO.

One month to go until the Tokyo Motor Show

:D :D :D

that is like the world series of car shows

It does indeed share the nose of the Mazda6 and the tail of the RX-8. It also leans toward the last generation Lexus SC coupes (300 & 400). As with all production cars, Mazda will bold some fender lines and put a hell of an engine in the final car.

I've always admired Mazda for daring to be different; something that just can't and won't be said of the other car manufacturers. (remember the Miller cycle engine in the Millenia)?

I think that cash shortfalls and marketing were the downfall of the company. With Ford backing them this should not be an issue; nor should this whole dilemma about the 247 down to 238 hp. Ford/Mazda should make it right. I trust that they are re-working the ECU's for the 2005 model year. All in all, the little quirks that are happening to/with the 8 is just another example of how companies use us as consumers to be their Beta Testers. Modifications and improvements should be forthcoming. (At least I hope so).

As I went to my local dealer this morning and walked the lot, looking at all 30 RX-8's they had in stock, I came away with the feeling that I'm still going to buy an RX-8 because I belive in the philosphy of Mazda and what they try to encompass with the cars; the fun factor.:)

Yeah, me too ... right now there is no other car that is out, that I would want to own ... other than the RX-8!

Personally, since I already had to get a new car, earlier in the year, I can now afford to wait a few more years until all of those needed improvements on the RX-8 are forthcoming!

:D

WOW that car looks like something i flushed down the toilet this morning..sorry guys...

It kinda makes me think of this http://www.davrodigital.co.uk/galleries/gallery33/gallery33images/aston-martin-7.jpg http://www.cartoday.com/images/news/2003/9/rx7.jpg

No, it looks like Mazda 6.

If its really going to be a 7, they'll be sure and give it more aggressive lines. I would hope they bump the hp up to around 300. It has been a long waiting game for us 7 owners.

I am sure it will look different. I bought the 8 to tie me over until the 7 comes out.

I hope it is only a 3 year plan. :)

when is that 7 suppost to be in the strrets?

It's all speculation.

hopefully soonnnnnnnnnnn

isn't a "new" 7 supposed to appear at the 2004 tokyo auto show?

or at least some project car or something..

again speculation

This is a magazine article here in AUS

http://members.optushome.com.au/m0j0/rx7/newrx7%20copy.jpg

thanks for the article mojo!!

i think as an addition of the wider rotors, they should also add another one :D

that'll take care of any possible false HP ratings :D

mojo
that pics looks better IMO

That concept makes it look like a 6 and and RX8 mated. Wonder who was on top? :D

Did I do the math correctly? Is 240 KW equal to about 320 horsepower? If so, I can hardly wait! :D

IF THAT THING IS 320HP IT WILL FLY

i just hope it looks better

I thought the engine was a 1.3 litre? That's what it says on my spec's....

Nope, everything I've seen points towards a 1.5 or 1.6 ltr twin rotor.

He means the first post of this thread. Anyways 2.6L I believe is when RENESIS is working, but 1.3L when its off? So 3.2L would be 1.6L in our known terms.

What are you people talking about? Go to Mazda.com look at the Specs of the engine and it clearly states that the rx-8 motor is a 1.3 litre rotary engine!

Where are you poeple getting 1.8 and 3.6?

The Renasis in the RX-8 is a 1.3 ltr rotary. But that doesnt compare to a piston engine, it actualy brethes the same as a 2.6 piston engine (and as each rotor = 3 cylinders effectivly gives a 2.6 v6 equivelant). This is because of how often the chambers fire etc.

The next gen RX-7 engine is supposd to be a reworked renesis with either 1.5 or 1.6 ltr 2 rotor displacement giving a piston equivelant of a 3.0 or 3.2


Other options include a turbo'd renases 1.3 or a 3 rotor 2.0litre, neither of which I think is likely.

I guess I understand now

The only thing that scares me about the new RX7 is well, the competition. Specifically the new Lotus Elise coming to the states. Toyota 4 cylinder power (reliable) in a 2000lb. chassis whittled by the handling gods themselves. Check out the latest R&T. Mazda is going to need to get it right and reliable. Sure, the Elise will be too minimalist for some, but it's a pure sports car capable of low 12's in the 1/4 and 30mpg on the highway! Sub $40K. I've been considering a three rotor conversion on my third gen but this new Elise really does it for me. And it's even more impractical (space wise) than my 7! :-) I hope the dynamics of the new 7 are more Elise than they are Boxter S. The S is a fine car, just too damn plush. Oh yeah, make the new 7 a vert!

This looks like another angle of what mojo posted. Pretty sharp IMO.

give it a rest. they don't know what they're doing, and don't understand the RX-7's lineage. it won't look like that.

the 13B-MSP is a 1.3L motor that breathes comparably to a 2.6L piston engine. stop confusing the issue. it is a 1.3L motor. it breathes 2.6L per two crank rotations, just like a 2.6L Otto cycle piston engine (wankel motors get the whole Otto cycle done in one rotation of the e-shaft, or 1/3 a rotation of the rotor (same thing)).

Here is another article/pic of the 2006 rx-7 concept. This looks a whole lot sharper than any of the others IMO.

Yeech. To each his own but I hope that R/T photo is just a diversion for the real RX-7. It looks like an old late 80's design of a cross between a 2nd gen and an RX-01.

floyd welcome
I think that pic looks great of the rx7

thats just a drawing, and hopefully the next 7 will look nothing like that
