Plus3, I did about a 50 miles turn around Phoenix area on Sunday on freeways mostly at 70 or so mph. My liftime mileage is up to 41.8 and seems to be staying there. Trip 1 showed mileage over 48 last week; after the running around and with my wife sitting in back commenting on how she wanted more air, myl Trip 1 mileage is down to 46.2 this morning. I did have the shade screen on the roof closed to minimize heat transfer.
When the temps get up over 100, I would guess we will take the hit on mpg.
Question: when sitting stopped in traffice, I still feel a goodly amount of cold air from teh a/c system. Is it totally running off the ICE, or does it use EV power when stopped or at low speeds? I have had other traditional cars where you could tell a rise of a degree or two at idle. At least I have not experienced that with Cmax so far.
