<div class='quotetop'>QUOTE(4-G-rim)</div><div class='quotemain'>I would just wait till they debut the actual production car EVO. I still believe its all speculation and of course its a concept car, so everything about it is concept even to the technology. I'll just wait till they finally debut the actual production EVO X, then i'll start criticizing. The only thing I am criticizing now is that there is no more 4G63...instead they are replacing it with a 2 liter Aluminum block motor. I'll have to see what this new motor is all about first though before I really start questioning it.</div>
mitsu is slowly swapping in aluminum for cast iron over time on all their cars.. Mostly as a reponse to people whining about "how heavy" cast iron is (never mind the fact that a cast iron 4 cylinder block only weighs about 75 pounds +/- more than aluminum.
whatever.. I have no doubt the block will be fine, as aluminum is easily strong enough if designed correctly.
the new outlander engine (debuting in fall) is an all new aluminum 3 liter v-6 with mivec. I suspect you'll see a trickle down effect to the rest of thier engines over the next 5 years.
