Hi guys, for a 2.5 hour 155 mile drive how much range would I lose by having the A/C on for an 85 degree day? Also how much range would I lose from the listed 250 mile range if I was going an average speed of 80 miles per hour instead of the base case? Seems like about 40 miles based on the graphs out there does that seem reasonable?

I have a P90d Model X ordered but am considering upgrading to 22 inch wheels. I make a 155 mile drive every summer weekend that I would like to avoid stopping at a supercharger for. Thanks in advance for the help!
