    Well, I'm in Florida and it's summer, so never really had the A/C off. But have a V with 1,700 miles and with a 48mpg over that time. I'm happy, and would expect a 3-5% improvement without A/C powered.

    Not if your other option is increased drag from rolled down windows, unless you enjoy getting fried inside the car.
