Windscreen covers help a lot with keeping the interior cool. Another thing is to crack the windows, just leave a tiny 1/4 inch of gap open. These two things has been the cooling tricks used for decades.

Thanks for doing this test Kim & PJ! I started using cabin overheat protection when I saw my Model 3 interior went up to 152° one summer while parked at church. 🥵 Lots of people are concerned about energy consumption, but from my experience when it’s on for 4 hours while I was at church, it only consumed 1% battery. It’s totally worth it to leave it on.

Couple other temp control tips:
* park in the shade if you are able.
* park with the front windshield facing away from the sun (sun hitting tinted rear windows directly doesn’t heat the car as quickly as coming directly in via the clear windshield.)
* roof sunshades and windshield sunshades can help out significantly.

These couple items can save a fairly significant amount of energy and keep your car cooler (whether Tesla/EV/gas car), especially when you may be doing several shorter stops.

+Window Tint

+Roof Sunshade (Can be removed at night/winter if passengers want to enjoy the view, but most passengers aren't looking up enjoying a 95 degree sun in their face in Summer)

+Thick front sunvisor when parked outside, these all combined really make a big difference in hot climates with the Tesla!

Good catch - that bug with overheat protection definitely needs to be fixed

Awesome video! Just a quick note though. The rear A/C does automatically come on when you have the AC in auto. It detects any weight on the seat and will kick on the air when it does. I believe it's around 15 lb give or take. But it's still good practice to do as you recommend and make sure the rear air is on.

For Florida summers I just keep a sun blocker in the front ceiling glass all summer.
I cut out some Everbuilt Double Sided Insulation (the silver bubble-wrap looking construction stuff), with some suction cups.

It's actually the effects of Infrared that causes the heat in your car not UV. The UV blocking tint will more or less protect you from sunburn. Even though UV has more energy, the wavelength is too narrow to cause kinetic energy buildup in molecules which would cause heat.

[Tokamak.]

Solar radiation arrives on Earth in many forms - visible light, UV and infrared are just some that we're used to measuring. Most of the heat that we feel arrives from infrared so a UV tint isn't going to do much for that. I put a IR blocking tint on my X and it does significantly cut down on the heat buildup. The seats and cabin surfaces don't get as hot. But the actual glass of that huge windshield does get insanely hot and will radiate latent heat into the cabin.

Tip: Leave one window down a crack so that the high pressure heat can escape from the cabin greenhouse instead of transferring its heat into the interior cabin materials. If you tinted you vehicle you can also attempt to park in such a way that the tinted rear/top of the vehicle is facing the sun (future sun if parked for a long time) since the front windshield is not visible light tinted. Most auto glass will absorb the majority of the UVB (the ones that cause tanning) but pass through UVA and IR - if you want to stop those from entering the cabin you'll need to have a tint applied and it can be done to the windshield legally and it shouldn't significantly interfere with visible light wavelengths - although it will cause some chromatic aberrations.

Hi, Kim. I live in south Florida and I can tell you I know from experience how that heat feels. I have a MY with black interior and I had to add ceramic tints. You don’t have to do dark tints 5/ 10/ 15% however, you can tint the windows and roof with a lighter tint i.e. 35%. I’ve seen my interior on 100 degree days dropped significantly after I added my ceramic tints. The ceramic tints are on the pricey side but they work. The car is much cooler now. Also, I use cabin heat protection. One issue I have as well is sometimes on my model Y, cabin heat protection does not turn on. I’ve tried 90, 95 & 100 at times to see if this would fix the issue and still does not turn on. I think there is a bug that Tesla needs to address. Great video and very informative.

I was in Croatia last year summer and we had 45 degrees Celsius outside all day long. First day my Tesla went to 65 degrees inside. Then I decided to switch on Camp mode and set it at the max temp of 28 degrees Celsius. Worked like a charm. I had the car plugged in all the time thanks to a 11kW charger on the lucury camp ground and it took about 5% per day only. I was pretty surprised but it seemed that most was needed to get it down from 65 to 28, keeping it there was not such an issue 🤷‍♂️

[Cloudtidus]

I have a white on white model Y best choice I made instead of going black the car gets cooler waaay faster within 2-3 minutes of starting the AC

[michaelgreen]

Thank You Kim & PJ for the amazing test on heat range inside each Tesla and How the X seamed to have a issue that Tesla should be able to fix, could be fatal for a child or Pet, You both do Amazing Vlog’s on so many subjects!!!

[dang]

Very interesting experiment Kim & PJ. PLEASE let viewers know… From the Owner Manual… “Cabin Overheat Protection operates until 12 hours has elapsed once you exit or until the Battery energy drops below 20%, whichever comes first. Using Cabin Overheat Protection requires energy from the Battery, which may decrease range.” SO MANY PEOPLE are not aware of these facts.

[ChristopherOden]

Definitely have run into the bug where it says the cabin protection is on but the interior view within the app clearly shows it's not working but haven't been able to consistently get it to trip so unsure what causes it. My only insight, use the same color crayon next time with every car so it's controlled, otherwise you run into the same issue where the different paint colors register at wide ranging temperatures so the crayons wouldn't melt the same way.

[arthurschalick]

I got reflective roof sunshades for my wife's Model 3. They work great. You don't feel the sun on your head. There is aside affect. I think they make the cabin little quieter.

[jonfscott]

I think you misunderstand the overheat feature. It is just the temperature you want it to turn on. Not the temperature it needs to keep it. It mostly uses air circulation to keep the material car interior from getting to hot and being destroyed. The keep it cool feature is for a specific temperature to keep you car comfortable as is dog mode.

[Magoo_Who]

Thank you for the Video. FYI: if you have issues with your cars climate system, you might want to check your cabin filters. changing your cabin filters will allow the system to do more air changes, and allow your car to cool much faster. I live on a dirt road, so I have to change my filters every year.

[jamess.]

I live in South Florida. I got UV tint on front doors and windshield which solved the problem completely. Quicksilver exterior and white interior and it never gets that bad. I use cabinet overheat when sun is shining all day and over 90 degrees but besides that, it’s incredible.

[melfullmer]

You should do a short video containing 10:20 - 11:55. That’s an excellent explanation of why car interiors get so hot so fast. Might save some lives.
