question for mazda fans (RX 7)

With all the news about the end of the RX 8, now every car mag has a MY 2013 for the new RX 7. (HOPEFULLY)

My current ride warranty ends Jan 1, 2012.

Question? When would Mazda start selling the RX 7 in the USA in 2012?

Thanks

The date hasn't been confirmed... Most sources expect it in 2012-2013 though. My guess.. we won't see it till 2013.

and that's only if we have a solid turn around in the auto market and they can bring the rotary in line with fuel consumption standards....I think they'll do it!

Yea they have some options. If it's true 2 door get rid of the back seat. If someone want a back seat let them buy a diff model. Then offer a Direct Injected 12a sized engine running on regular octane as the base with something like GSL-SE that has the 13b DI on super. And they should also offer production RE hydrogen duel fuel with it.

Vash,

Mazda has been working on a 1.6 rotary for several years now. The other designs that you mentioned will not remain.

The RX8 is so far above and beyond the ride and handling of any RX7, the only thing peeps miss in the HP and Torque. I for one would not like to see it. How about an RX9? The best of both models. Sick to death of the RX7 comeback.

The logic is this: The name 'RX-7' is powerful and recognized throughout the world. To not use that name would be a huge mistake. It would be the equivalent of Chevrolet not using the 'Camaro' name.

If it is a 2 door rotary sports car in the spirit of any of the previous coupes it needs to be called RX7.

I agreed with the 2 door and no back seat part.

12A sized on Regular Octane Pushing more than 232 hp on NA ? Is that even possible ? Cuz I remember the original 12A was pushing 100 hp and 90 something TQ. and the last one was pushing something like 160 hp with 140 ft tq. Thats why they have to go 13B, which is 80mm in size (rotor, 12A was 70mm if I remember correctly)

and the Hydrogen option ? where can you put Hydrogen ? can you tell me where is the closest Hydrogen station? Cuz as far as I know there is only a few in the whole country. so giving this option = no one will buy it.

I'm actually hoping Mazda could manage to turbocharge the 16x and keep emission/mpg to acceptable level and yeah... 2 seaters plz.

Not with Side port exhaust.

Its ok to Turbo/Super charge with Side port from Factory, but there are way too many unpredictable problems.

that have nothing to do with port placement the only real hurdle specific to the motor between the older and current generation rotaries, is tuning. tuning has always been big for us, but the compression jump to 10:1 gives even less room for error.

sure in the RX-8 some might argue that side/p-ports would make a difference in manifold limitations. but we are talking about a different motor and engine bays. IMHO if Mazda were to choose to do so, they could easily produce a 16X based FI motor that would make ~300-330 WHP.

But they have bigger issues, fuel consumption standards and especially emissions, Mazda is already facing a short time to sell RX-8s in Europe before new laws go into action that will ban sales due to not meeting emissions standards

If tuning can solve everything, Mazda don't need 16x at all.

Everything has a limit, once you reach that, you have to move on.

Sure I know people can port an NA and get around 300 hp, but remember this is a production car, not a race car, like you said they have a lot of goals to meet(Emission, MPG, etc), They just have to move on to the next size (16x)

sure in the RX-8 some might argue that side/p-ports would make a difference in manifold limitations. but we are talking about a different motor and engine bays. IMHO if Mazda were to choose to do so, they could easily produce a 16X based FI motor that would make ~300-330 WHP.
They could if they want to, but as a street car, they have to keep the warranty cost under control.

(you know how many STi/Evo even the new Genesis Coupe Engine blown up cuz those dumbasses just up their boost to Sky is the limit without any other mods? then they just return it back to stock then they cry and bitch at Subaru/Mitsubishi/Hyundai)


But they have bigger issues, fuel consumption standards and especially emissions, Mazda is already facing a short time to sell RX-8s in Europe before new laws go into action that will ban sales due to not meeting emissions standards
I dont think Mazda cares anymore, Not like Rx-8 is a hot seller in the first place. I heard another source said that Mazda actually spent about the same amount of money for R&D on the S2 RX-8 (compare to the original RX-8), if thats really the case, all I can say is WOW. they really love Rotary.

Well I agree with this totally. But I do not car what they call it.

My short list for my new 2013 car is.

1. RX 7/9
2. Redesigned BMW 1 coupe

Compared to the current 13B-MSP the 16X has a redesigned engine geometry to create a better burning mixture (less flame quenching). This is described in the 16X patent. Basically the combustion chamber is thinner and the two plugs are farther apart. This allows the mixture to burn longer before the flame fronts hit the combustion chamber wall.

It has to do with the rate at which the flames spread in various directions. The flames from the leading and trailing plugs travel towards each other at a faster rate then they travel sideways toward the combustion chamber walls. So by making the combustion chamber thinner and the plugs farther apart, more mixture is burned before the leading and trailing flames collide.

Same body and suspension as what, the RX8 or the last FD RX7? Since we are in 2010 and this can come no sooner than 2013, there is 0 chance it will have the same body as anything from the past. No need to worry friend.

what ever it is im still gonna get it.I knew what i was getting when i baught my 8 and if ic ould go back id do it all over again..
I have debated selling the car time and time again but honestly its soo much fun! and its not to common as s2k's 350z's and other cars in its class. only thing that sucks is time will eventually catch up to it and it will be outdated.. (I like new things) =D

Personally I thought the RX 8 was outdated when I bought my current ride. (2008 335i coupe). I was wrong. Mazda kept it going, and it is still a desirable car for ride and drive.

I am extremely interested in the new RX 7/9 and what direction Mazda is going with styling and chassis.

I know they will hit the mark, that is why it is worth waiting for.

I think Mazda do that to get better emission, maybe a little bit more power.

Lets bring back the Thermal Reactor !!!!!!!! IT SOLVES EVERYTHING !

I'll jump in here with my own observations. I own an 07 RX8, it has been paid for since new. It's my only car. I'm a low mileage driver with about 18K on it, 11k of those miles have been on 3 longish road trips. I(lovingly) maintain it by the book, I've had a lot of new cars and a few used ones over the last 50 years, this is the favorite of maybe 3 other favorite cars. My RX8 is both garaged and covered when not driven.

I bought it not so much because it was a rotary, but because it had a combination of unique features…4 doors, 4 seats, excellent balanced performance, excellent suspension, high value for the money, the merits of the rotary engine and the RX8's unique looks. The RX7 was never a car that appealed to me.

If I had wanted a 2 seat sports car I would already have one. There are and were a number of very good ones to choose from, including Mazda's own MX5/Miata.

When I crossed shopped the RX8, the only other car at the time that I seriously considered was the Audi TT…a car which I still like.

Since I prefer a car with 4 seats, a 2 seat only RX7 is not in my future, a 2+2…maybe. I'm holding off replacing my RX8 because I like it so much and I'm waiting to see what comes next. but if it is a 2 seat only RX7 type, then the Audi TT or BMW 135 is probably my next car.

^... but if the 'new RX-7' does come out in a 2-seat, then I'd go that route vs. a Cayman S, so ....

Remember that the Rx-7 has always been a Porsche 911 style 4 seater since day 1 in Japan. In the US the rear seats were only offered in certain non turbo models of the 2nd generation cars.

i differentiate between a well developed 4 seat coupe such as the RX8 and a 2+2, in which the rear seats are only incidental and not really intended for 2 adults for a very long period of time. For that reason and for me the RX8 is ideal, the RX7 2+2 is marginally ok, and a 2 seater only RX7 is out of the question. I've indicated this to Mazda in response to customer questionnaires i've received from them on a couple of occasions over the past couple of years.
