Is AC powerful enough for AZ summers?

    That is only if you have the rear HVAC set to Auto. You can force it on and then the second row door fans and the third row fans come in. In my experience the second row fans on the back of the center console sync with the front HVAC settings.

    We discovered this because our child seat in the second row and our dogs in the third row apparently weren't heavy enough to trigger the rear HVAC on auto and we have to turn it on manually.

    Not Tucson or Flag, but we just did a drop from Chandler to Heber (bit past Payson and not far from Holbrook where the supercharger is) and it handled the mountains with ease. Used ~380-400 wh/mi average going up, we left with ~90% battery and arrived at ~18%.

    My X is Black interior and headliner with Midnight silver exterior. No issues. Also, the X seems very efficient when cooling. I never notice the fan at high speed.

    Three years with my MS. On a 112º day in Arizona you will want to keep a baseline minimum amount of energy, say 50 miles of range. When it is extremely hot and you are traveling between superchargers or home as you get low on energy (<50) the car will reduce A/C cooling; probably to maintain battery pack cooling management. My experience comes from lessons learned. Traveling from supercharger to supercharger on a 112º day I was running to almost zero miles to get the rapid s u p e r c h a g e. As I did so I noticed the cabin getting very warm and the A/C and fan almost off as my mileage remaining declined close to empty! Duh! Supercharged and planned to arrive at the next supercharger with at least 50 miles remaining and had no further issues staying comfortable and, at times, chilly. In any extreme, hot or cold, the car manages the battery pack first and us well, second. Note the stories from those folks that live in extreme cold. Interior heating takes a toll on range also as the battery pack takes priority.

    It has only hit 90 here in DFW area... according to my home weather station. I have turned off Range mode and drive around with my MX on Auto for all settings. It has seemed fine so far

    Well it hit 100 today. Still not 110+. (But supposedly that's on its way later this week.)

    But today, I had to turn the AC down cuz it was downright chilly in the X. At one point, had to move the climate control from 72 to 74.

    So far, so good.

    This week, while our garage is under construction, I'll have to have it baking on the street all day if anyone wants to come check it out. Biltmore area.

    Sounds like the hardware is quite adequate - and all the "me-too" are confirming. Just select the right fan speed and all these cooling issues are handled by the scroll compressor. Gosh - I like good engineering!!!!

    I use 3M coating at 70% on my S and also use the Tesla aftersale sunscreens. Those have made it work well even without precooling in the hot humid South Florida summer. AZ is hotter and dryer/

    I have no automotive experience in both places in summer but I have aircraft experience. At 128 degrees a few years ago leaving PHX airliners could not start engines, but I could. Cooling in AZ was faster and easier to maintain that it was later the same day when I was starting at a Miami area airport with temperature of 96 and humidity of 95%. I only recall that because I wrote it all in my logbook. BTW, the A/C in the airplane in question was an automotive unit.

    I will be surprised if the X will have a serious problem so long as you tint the huge window and precool.

    Tell me your opinion on Coating. Others say gotta have wraps, bras, cquartz, xcel...."mines the best" and at prices that range from $5,00 to $15,000.
    Do they hold up? do they protect better than a paint job at 50,000 miles? is it worth it? your opinion please.

    1. I did no additional tinting other than to purchase a few greens squares from Sporty's Pilot Shop for the front window. No A/C problems.
    2. I did wrap the car with Suntek and it's just fine after over three years and 70K miles. I had every painted surface wrapped and it's saved the paint numerous times--rubs from other cars just wipe off with bug and tar remover. (Too bad about the hail damage but that's what happens in Texas).
    3. I've never had an aftermarket paint job that was anywhere near as good as the original in terms of looks or longevity. Anything you can do to keep the original paint in good condition is money saved. (and a good paint job is about 3X to 4X the cost of Xpel or Suntek).

    Thanks. I've never wrapped, just tinted windows and thought that was repeatable. Tint shop showed me his edge wrapping - looked OK, but I thought not worth the price/effort for the protection. I was hoping for just the user history you just shared.

    Note that the main thing about the protection film is how it's applied, it's still more an art than a science. Look carefully at the previous jobs before choosing an installer.

    I did a complete job with everything. I bought a demo car that had had some rough treatment so Fist Impression of Saraspta, FL did the whole job. I chose them because they are the sponsored link for Florida Tesla Enthusiasts and I'd seen several cars they'd done. It has been worth it to me already. A careless driver bumped into me and my only damage was replacing the film. Some time ago I backed carelessly and bumped a post. It looked terrible but everyhing cleaned away with mild dishwashing soap. Then washing the car is a breeze but it rarely gets dirty.

    Frankly you need to be a bit obsessive to do this:

    We parked our silver exterior with black interior MX outdoors in Novato,CA on 2016/05/29 for about 5 hours in the mid-day. Weather Underground says that was a 82 degree high day. It was a very sunny day, regardless of the temps. Getting back into the car it was quite hot. The instrument cluster was reading in the 90's (I'm not sure where this exterior sensor is located).

    The AC seemed inadequate, at some point we rolled down the windows to get the car to cool off. Then I noticed that the fan was set to auto, but was only at 6/10. I turned the fan up manually and things seemed a bit better. I'm not sure why "auto" isn't more aggressive initially when the car is clearly very hot?

    That really sounds like range mode is on. Range mode reduces both compressor power and fan speed to make the car consume less energy - and recent findings suggest it runs the battery warmer, too - which may or may not have adverse effects to longevity.

    I have heard when not in range mode the fan goes to 11.
