If you're looking at Atkinson cycle, that's a whole different topic. And we do have a discussion about that. I haven't checked on it lately though.
I still can't believe you're considering experimenting on a new car.
If you're going to do it, get it tuned by an E85 guru. Don't risk your engine.

Ethanol is infact heavier than Gasoline. Being 33% oxygen makes it heavier and reduces it's energy density. It's also what makes it so energy efficient.
