That would affect rolling resistance, for sure. But I'm not sure how inertia affects EPA measurements. They run the vehicles on a dynamometer. I know they try to simulate friction and aero resistance. I don't know what they do about inertia. BTW, in reading up on EPA testing, I learned that they now DO have a cycle that's carried out with the aircon on, and one that's run with heat on. Interesting info on the whole process here : http://www.caranddriver.com/features/the-truth-about-epa-city-highway-mpg- estimates http://v.gd/YAYXDp So how efficient is the Tesla's HVAC?
