i am keeping my fingures crossed. either i keep my rx8 untill the next rotary car (rx7 i hope) 0ctober 26 2007 is the decisive day for me. or my car goes and the new 370z, or the new supra takes its place.

What excites you about the name RX7? Is it the name it's self, the turbo , the horsepower? There were 10X more non-turbo versions of the RX7 on the street than the turbo version. The turbo version stock only had 15 more horsepower than a stock RX8 (245 verses 232). This isn't a criticism, I want to know what the magic is.

There's just something about the name RX-7 that has a mystique to it. Call it tradition, legacy, call it what you want, that name will always bring about passionate thoughts from many.

Is it up there with names like Shelby, Testarosa, or Supra?? Who knows...to some it may be.

lov2bugu

its not just the name man, i mean the rx7 looked good and still looks good even after 10 years. i dont know what makes me whishing the rx7 to come back, but maybe the thought that it was that famouse befor, and to be revived again is just really cool. just like the gt-r, supra, mustang old but modern look. its soooooo coool.


even thought what ever rotary coupe that looks hot comes out i am buying.

the name rx7 brings great images in my heart. The 3rd gen is the one that i am refering to. it beats NSXs and GTR 34 on the Tsubuku track. It's the best of all rotaries ever made in terms of preformace.

They will never make another RX7

I bet that 34 of those cars will be new, bland econo-compacts.

Though I can see how the name can make it seem more appealing, it honestly doesn't matter what name they stick on it. The biggest purpose I can see using names like "rx-7" to refer to the new rotary car is that it gives a point of reference for the design. If it's a 2 door coupe w/ hatchback and has a turbo and N/A option, it's a lot closer to being the new rx-7 than the new rx-8, even if that's not what they choose to call it, it's the most common reference people would get and be able to relate it to. I must agree that I hope it's something lighter than the 8 with more power.

honestly it looks like it can be producted, i wonder if they are going to. i just think they need to convince another auto maker to join the rotary wagon. imagine how that engine can be improved when there is competetion.

Please dont talk about the GT-R like that, its coming to hunt you and all those no believers soon LIKE VERY VERY SOON

the gtr seems pretty heavy

I think people favor the idea of a "new RX-7" because of the history it has...it has always been the opposite direction of what other car companies make their performance cars to be...instead of using big heavy engines..it has an engine half the size of a standard compact car engine W/ a turbo option...it had a light/stiff chasis where other competitors like the 300zx and supra were quite heavier and the weight was noticeable when driving aggressively....it was well ballanced performance/handling/braking where other heavier cars relied on over powered engines to launch the car, massive amounts of body roll, and inferior braking....i think thats why when people hear the term RX-7, they get excited because they expect the car to live up to its name.

honestly thats the reason why i purchased the RX-8 although i already knew it was not an RX-7 replacement, but ore of a vehicle that embodies much of the "RX" Spirit...and in all honesty ive been quite satisfied with the car and its abilities.

and to the FD only having 15+ more hp, that cant be true at all, unless its at the crank or somethin cause i remember stock FD's dynoing close to advertised hp to the wheels, and we all know how much of a struggle it is to break 200whp W/ MODS in an rx8.

dillsrotary

the fd had more hp/torque sooner in the power band which is what made the difference

Turbos will do that.

Here's just something to think about. The RX-8 from the handling department is every bit the 3rd gen RX-7's equal and more. Mazda has some great video of an RX-8 chasing the RX-7 on the Myoshi proving grounds. The 7 would pull away in the straights but the 8 would catch up in the corners. 7 owners don't believe this and having driven both cars it's not hard to believe they think that way. Both cars feel so different from each other that the only way to truly see the differences is to run them side by side as the Mazda footage did. So we've established that in terms of handling, the 8 is more capable. At least stock but that's all we care about. It's chassis is 100% stiffer too.

The new car if the rumors and info we got are in fact true, will be another pure sports car. If they aren't concentrating on a true 4 seater as the 8 is, you know it will be lighter. Maybe not 2700 lbs light but still sub 3000 lbs. Lighter is better when it comes to sports cars. The new long stroke engine will most certainly have more low end grunt than the Renesis as well as more power. It should really feel like what it is and that's a bigger engine. The jump from 1.3 to 1.55L may not sound like much but go drive a 12A equipped car and then a 13B equipped car back to back. You definitely see a difference in power. This should be a nice power increase across the board.

Compared to the last RX-7, the RX-8 has a lighter flywheel, driveshaft, and 6 speeds. The rear diff I don't care about as my hopes are that the new car with more torque will go back down to the 4:10 rear end as the 8 should have had. Hopefully the long stroke will be direct injected and all aluminum but we'll see. Now lets be conservative and say it'll have 275 hp. I'm not going to guess 300 as I don't think it is that high. Let's also assume it actually hits this number. If the car is 2800 lbs or so, it'll be quick. Lighter rotating drivetrain parts and 6 speeds will get it moving nicely. You can almost guarantee that it will at least be the 8's equal in terms of handling and hopefully surpass it. That means it'll be a superior handing car compared to the last RX-7. With the new engine/transmission combo, all it has to do is equal the RX-7 in terms of acceleration and it's an all around superior car to the last 7 which makes it a worthy vehicle when it comes to carrying the 7 name forward. We don't know it that's the case though but it isn't hard to see all of this coming true.

Also keep in mind that while the engine is larger, if it does in fact have direct injection, it would be more fuel efficient. This may be enough of a benefit to compensate for the fact that it's larger. Then again, maybe not quite. If the new car is a couple to a few hundred pounds lighter and the rear end gearing goes back down to 4:10 or so, it may actually work out to be a more fuel efficient vehicle than the RX-8. If it's a pure sports car, no one will really complain anyways. If you could have handling that was better than the last RX-7, acceleration that could at the very least match if not exceed it, and fuel economy better than the 8, would you be happy? I would!

Come on Tokyo! I want to see if we've been had or not.

Renesis_8

Changing from 2.6L to 3.1L is a huge change in a piston engine (Just for the sake of comparing).

Just one more month. Its amazing what Mazda does to the Rotary. A lot of us thought that the Renesis cannot be improved any further (max intake/exhaust area, maxed out NA, not idea for 3-rotor, etc etc.). A displacement increase really didnt make much sense back then, increasing the width wouldnt solve anything on the 13B, and making a 'long stroke' was impossible since retooling would cost too much.

Again, Mazda takes the tough road, takes the risk and retool for a 15C. 15C is probably the only hope of keeping the rotary alive.

With the new 15C, maybe Mazda could really integrate all the ideas that have been floating around to improve the rotary engine. Starting with a clean sheet design (Renesis wasn't), they can add Direct Injection and all aluminum rotor housings much easier.

And if your predictions are right RG, a 15C 2800lb 2-seater will be a hack of a sports car. If Mazda is fully committed to this, the next RX-7 will be the best handling car from Japan.

(Lightweight, Low center of gravity, mass centered around the middle, small frontal area, and many more advantages rotary brings when designing a car)

fwiw, the 'Zoom-Zoom' magazine i received on Monday specifically says '2 seat sports car' as the last of the Mazda 'Flow' concept cars to be shown at Tokyo Auto Show...

When you think about it, were we really wrong? The Renesis isn't easy to improve on. That's why it's getting larger. The 3 rotor idea isn't a very feasible idea. Larger didn't seem to make sense but when you see a whole package potentially put together, it appears it does. The smaller with forced induction seemed like a nice route to go and other car companies are doing this. Turbos do add weight though so you won't really save on the weight front. Mazda has never had terribly good longterm luck with the turbo rotary so it's not hard to see why they are going this route. I figured that they'd have finally worked all of that out by now. The rotary exhaust is just too damned hot.

Renesis_8

Here is another interesting thought.

Peripheral port 15C!!! or rather... 2.325L, 23C

C'mon, the RX-7 is the rotaryrocket. Mazda & owners amassed an incredible number of race wins under the RX-7 name, its a legend.

i just hope that if mazda does bring back the rx-7 that they don't bastardize it and they do its name justice
