yeah they changed the ports on the new rotary so it's much betta. they're both on the side housings which eliminated all the overlap from the old engine (that made the BAPBAPBAP sound. also since there's no overlap, exhaust isnt mixing into the fresh charge and fucking it all up and making it have to run super-rich just to fire so hopefully it'll be better on gas as well. and though they call it a 1.3 liter motor. .. . it isnt. i'll avoid the long drawn out explanation but if you use the same math thats used to find piston-engines' displacement then it's actually closer to a 2.6 liter engine.
