Just saw it looking for more info on the 3.6. Pretty cool

That website didn't like me, or else my hate of unnecessary cookies, but I found another with the same article that didn't mind.

Anyway, there's awesome stuff going on with GM's high-feature family of engines. Here's hoping that they actually make it into the US in something other than a boat of a luxury car. Can you imagine if they built these engines for a redline of something like 8500 rpm, instead of (I'm guessing) 6500 or 7000 rpm? 100hp/liter NA, stock... with an idle as smooth as a baby's bottom and 250 lb*ft of torque from 2500 rpm thanks to all sorts of intake, cam, and valve wizardry.

VVT must be controlled with the ECM or something....hmmm. I wonder how much GM is 'downgrading' the performance via programming...
