i can see this in application by the end of the next year. 35mpg average here we come.
now i'm somewhat confured though, i know hcci comusts gasoline by compression, but is gm working on a system where they inject water into the cylinder every fourth cycle to reduce the gas usage further or is that a different system that i'm thinking of?
