Yeah, that is one thing I wish the HCH would have is EV mode. Maybe they will do that next time with a larger battery. But, I mean there are chips people put in their Corvette to change the fuel mixture, intake patterns, etc, to get more horsepower and efficiency. I would think that there was something out there that could modify Honda's already efficient engine and/or battery/engine cooperation to eak a few more mpg's out of it.
