Hi Buzz70:

___Unfortunately, a 30 - 40 mpg drop when using A/C is a reality for Insight 5-speed hypermilers. For Insight owning non-hypermilers, they don’t receive EPA estimates anyway so a 15 - 25 mpg drop is about right … When the Insight first arrived on our shores, the NREL had one for testing and found an ~ 35% overall drop in fuel economy when using A/C under a variety of driving conditions.

___Good Luck
