Some folks have had good results with those folding sunshades that go in the front windshield area while parked.

So far A/C in desert with temp around 100, the outlet temp has been about 42-45 when on recirculate medium speed and quite frankly will freeze you out if the temp setting is too low.


Soooo.........question answered so far in actual test conditions is "a/c is very strong".


Don't know if we will get in some of the "real" desert conditions of 110-120 anytime on the return trip, but if so I will post those results.


Thanks again for all of the replies to my original post.

I'm in mid atlantic which gets quite hot (100+) and humid.  The a/c works well.  However, the thermostat (temperature setting) isn't accurate, about 6 degrees "warm", so you need to compensate by setting lower.  Given that the a/c can pull 5kw that means its 3-5 tons which is bigger than in most houses.

I'm in Phoenix, and I can say the A/C works really good, the only downside is ICE engaged for system performance because it has been 105 plus and the batteries heat up pretty quick

Well, the total trip was over 5000 miles from Atlanta to San Diego via Colorado Springs, CO across the Rockies through Las Vegas with the return via Arizona, New Mexico, Texas etc.


When we went through Arizona/New Mexico, temps were up to about 105. A/C is cold enough to "hang meat" if you want it that low. Really strong.


This will no doubt rub the hyper milers a little raw, but we just put the car in drive and drove at posted speed plus about 3 or 4 mph without concerning ourselves with mpg extension techniques. Running at freeway speeds the mpg was about 38-40. I'm don't judge the car on EPA ratings etc. The bottom line is that we like it! It's roomy, handles well, runs quietly, has plenty of mountain climbing power, climate control is comfy and we could just blow by lots of filling stations.


I would charge the HVB at hotels when an outside receptacle was available and drove in EV later mode. To help remember to reselect EV later when stops were made, I placed an empty Starbucks cup on the shifter when we stopped for a break. Often stayed in the car when eating a burger  and ran the A/C. No overheating problems with engine which occasionally kicked on to recharge HVB for cooling energy used. Why run in EV later? Well, I figured that in the unlikely event we had engine problems and got stranded in the desert there would be several hours of A/C cooling capability, especially since we were traveling with our little Pomeranian. Hey, I also carried plenty of drinking water plus 2 gallons of distilled water for cooling system if needed plus that was also drinkable. Maybe overkill, but didn't take a lots of effort.


Go take a road trip. You will enjoy it!
