Look dumb a$$, I said you were right the displacement is 1.3L, this is however very misleading. You should call it a 1.3L-rotary like anyone with some intelligence would call it. There is a simple matter of when you compare it to a conventional engine you can not say that it behaves like a 1.3L it is more like a 2.6 due to the face of it being a two-stroke engine.
"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 645cc, so by Mazda's two-stroke method, a 13B is 1308cc. When comparing it to a four-stroke method, which it is what we are doing when we compare it to other cars out there. One ends up with 2616cc."
My point, saying that the RX-8 has half the displacement of my 2.5L is just not correct. You are comparing apples and oranges. Though you would not be correct calling it a 2.6 L you would be a little closer.
-I am not saying that Mazda is wrong, I just think there is a better way when comparing the renesis to regular engines.
-High school math? Must have missed that in engineering
