Good weather has one heck of a tank going. This tank was 88.5 mpg displayed at the RTP so at the pump it should calculate at about 85 mpgif I can keep it up. Color me excited! The weather forcast is looking favorable for a record tank.
Haha, it's removal of energy from the ambient air to avoid excessive perspiration and discomfort to the driver. Ambient air which the car has indicated was 119 degrees a couple times. I think 119 is what it maxes out at.
We're on a cooling trend this last wee, only 101 today according to the car.
119 is crazy hot! It has been around 100 every day for weeks and looks like another week of 100 coming up. That much heat really does not bother me for the 17 mile trip to work with a wet head from freshly washed hair. Humid conditions will cause me to kick on the AC faster than plain ole heat. I've needed to kick the AC on at 70 degrees so I could see out the windshield on really humid days. A 75 degree day at 100% humidity feels worse (to me anyway) than a 100 degree does at lesser humidity.
AC definately kills mpg, I'm not sure about open windows.
I have long hair and hate having the window open because my hair gets blown in my face. I'm a windows up driver. Keeping your windows up has the advantage that when it rains I'm not running out to the parking lot getting soaked while rolling the windows up. Even if having the windows down somehow helped mpg I'd still drive with em up.
