Hi pdexta,
I have a 2010 Ford Fusion hybrid. It has an electric A/C and I get about the same mpg hit during the hottest days. My usual daily commute gets me 49 to 50 mpg. During the worst days this summer (reported high 115 deg. but the temp sensor in the car while on the freeway read 122) the mileage dropped to 35.
I also take a hit when it's cold. I doubt the heater has any effect on economy, but the colder, denser air does.
