    Very interesting news. Do these engines get "extra" displacement?

    Detroit Free Press cited 2.2 liters. I don't know what the production engines measure out to be, but 2.2 liters doesn't sound like "extra."

    Not sure why they are continuing with the RX8 body?

    Looks like this will run in a new GX class.

    I noticed (on a different web page than the link above) that Mazda plans to introduce a skyactive diesel in their production line up.

    If it actually happens, it will be interesting to see if it is available in a truck or a car - or both - and if it available outside of Japan. Maybe an "RX-9" (aka RX-8d)? Good bye rotary, hello "donk" (Australian for diesel).

    Probably because the existing RX8 grand am chassis are tube frame and can easily be modified to take any sort of engine.

    That's kind of what I mean; can't they slap any bodywork on that thing? Why not use a Mazda 6 or some car they are actually selling?

    I'll never fully understand the relationship between car manufacturers and professional racing.

    Not a rotary. That sucks. A diesel rotary makes sense to me, since rotaries burn a mix of gas with a little oil, and diesels are called "oil burners."

    ^ but imagine, now RX8s can be reliable enduro cars, instead of running premix, and breaking down 8 times over the course of the last 4 hours at thunderhill...

    Why spend the extra cash on something that isn't needed?
    You have a car that is fully developed and can take the engine , you can call it R&D and be done with it.

    BTW, what you're describing was done by GM when they started selling the new Camaro, they slapped the bodywork over the same tube chassis of whatever "Pontiac" they ran before IIRC.

    If they made a street version I might buy one. I can't justify a sporty car that gets the truck gas mileage of the rotary.

    Mazda is kind of retarded like that.
    They built a good chassis with decent suspension and reasonable looks, and then stuffed the awful Renesis into it to make the die hard rotor heads happy.
    Well, after the initial enthusiasm wore off they sold what, 9 cars?

    Instead, they should've taken the 2.3L DISI turbo engine form the MS3 and put that in a chassis than doesn't torque steer itself into a different zip code every time you hit the gas and call it Mazda MX-8 or something...
    That combo would have been so much better because A: the car would have actually been fast, the Renessis is a totally gutless POS, B: get much more reasonable gas mileage and not 13 MPG, C: reliable, and D: less scary for people to own.
    The MX-8 would have sold a gazillion more cars than the RX-8 ever did.

    The new Scion FR-S / Subaru BRZ is another example for Mazda's brain freeze.
    For 20+ years of the Miata they had all the R&D for an affordable coupe done already and they could just beaten some new sheet metal and answer the demand from everyone that will now be buying the Scion and Subaru (and their mom).
    Instead, they made some lame limited edition Miata Coupe that was only sold in Japan and never went any further with it...
    The FR-S / BRZ has a pretty good chance at killing the next gen Miata, the NC barely sells as it is...
    Let's hope that the co-op with Alfa Romeo leads to something worthy of the enthusiasts deposits.

    I heard a rumor that a new RX3 might be in the works as a rival to the FRS/BRZ. Would be cool to see the old name used again, although would much rather see a new RX7.

    A neo rx3 would be cool! If it has pistons then it would be called a 808
    If nothing happens and there is no one around why did it not happen?

    I agree with Moti above. I have a dream of buying a decent RX-8 with a bad motor and dropping a 2.5 or hybrid 2.0/2.5 piston engine in it.

    Mazda has the ability to build more cool cars, they need to get back to it.

    Not everyone is as skilled with a torch and welder as you are, Moti.
