Nissan Motor Co. said it has developed a new type of paint that significantly reduces the temperature inside vehicles parked in direct sunlight.
The surface of a car coated with the innovative material remains up to 12 degrees cooler than that of a vehicle with standard paint, tests showed.
The company said the coating material can help rein in the temperature rise not only on the car’s body but also in the vehicle when exposed to direct sunlight.

can i paint my house with that?
There’s already a 98% paint, not that cheap last I checked though.
I have a similar coating on my deck in the back yard. I can stand on it barefoot comfortably in the summer which is not possible without the coating.
Nanoparticle roof shingles are a thing and they really work well
Got in my car after work yesterday and it was 102F inside. It was awful
Lucky! I’ve seen 150 here in Louisiana.
And even higher when I lived in the Mojave desert. Like, if you didn’t leave a window cracked there’s a real chance your windshield cracks.
Must have had you wishing for a nuclear winter.
It’s not so much the thermometer temp here in Louisiana. It’s the 80-99% humidity. At these levels your body’s main heat defense: Sweat - no longer works as it can’t evaporate fast enough or at all. Then it becomes an insulator and a feedback loop of hell. Like being wrapped up in a wet electric blanket.
I live in Pa, so our weather isn’t crazy hot like the south. I can’t imagine the weather where you’ve lived. 85F is my upper limit. Anything over makes me feel like I’m going to die.
I was working outside in 96F and nearly 50% humidity within the past week.
If we continue trying to work outside during the middle of the summer day, as our summers get hotter every year, people are going to start to die.
I wonder how many it will take for America to adjust. I assume a lot more than I’m comfortable with.
I was outside in 96F yesterday herding my ducks for 10 mins and my whole night was ruined because I got so sick from the heat.
Idk how people who work outside constantly do it
Box fans and Popsicles, mostly. You get used to it. Doesn’t make it any more pleasant though. I did give myself some pretty bad heat exhaustion at one point earlier this year, that hasn’t happened before.
Short bursts, finding shade, and lots of water and wind (box fans, as the other fella mentioned). A good hat helps immensely. If you can duck inside someone’s AC, you take the fresh air like it’s the last soup you’ll ever have and you suck it in.
I can remember a few summers in the desert where it would reach 130’s. And as a kid back in the early 90’s, we had the hole in the ozone too. No joke we had ozone warnings, and no outside recess cuz of it.
Plenty of summer nights were the temp never dropped below ~100f
Strangely, we often got winter temps below freezing.
There’s no paint on the planet that will make most of their cars cool.
Yeah, the Leaf doesn’t need any help being cool*, they’re as neat as they come
*just don’t mention gen 1 air-cooled battery pack degradation
Anything to not add a cooling system to the ev batteries.
Nissan also detects you having sex in the car and phones the info home.
My wife’s going to be pissed when she gets that call…
I’m curious where that’s from? News, or you made up from privacy policy?
Mozilla’s analysis if the policies, see my other comment in the thread.
Okay, I found one.
But I guess it’s to clarify what kind of data could possibly be collected and not that they actively collect and use them. I guess Ford can do that too, although they don’t specify in their privacy policy.
They’re not interested in your sexual orientation.
So fucking glad I got my car before they added all this shit.
It’s going to prevent me from getting any EVs that come out that I can afford too. I’m not signing a fucking privacy policy for a car.
Yeah, EVs are the worst kind of the privacy-invasive cars I agree
My car has an antenna for a network that no longer exists and I’m so happy about it
But, like, why is that listed then? Why would Kia and Nissan say they collect information on your “sex life” and “sexual activity” respectively of they’re not? What’s to gain from keeping the window open if you’re using it?
What ahaha.
Their privacy policy includes a provision that they can use the cameras and GPS to infer things such as sexual orientation, so yeah.
While this fucked up, documenting sexual orientation is not exactly recording sex. Someone could simply use GPS and see that the only place in the area that’s open is the gay bar and infer from that, or even lip reading.

no.
Which cameras?
I don’t think they have interior cameras (although other manufacturers do), but the front and backup camera feeds provide plenty of information as well.
Then there’s also this, if you need any more reason to be concerned.
I don’t think they have interior cameras
Can just stop there. Unless people are banging on the bonnet, not sure what the point is.
If you read the linked article you will find that exterior cameras feeds are plenty invasive enough.
I don’t disagree, but this is what was said:
Nissan also detects you having sex in the car
Unless there are cameras in the car then no.
Forget Nissan but I’ll take the paint.
It’s a cool, cool summer.
Yeah but 350Z tho
There’s a very long list of two door sports cars I’d buy instead of one of those bloated excuses.
I’d like to see that list, cause I’m I’m considering selling the car in a year or two. Requirements: 2 doors, convertable, 300+ BHP, manual transmission, stability control (cause I’m a bad driver lol), under $15K.
Miata, BRZ, GT86, possibly a WRX if you want something more practical.
Already considered all of those before buying the Z. None of them meet my horsepower requirements. And the last time I checked, they don’t make a convertible WRX and BRZ/FRS/86.
I mean, if you’re a middle age bro with a retail supervisor job compensating to show off to teen girls, I guess.
I see, thanks for pointing out that I’m a stereotype. FML
TBF, the 350Z was the sports car to have when I was a teenager. Not my fault that I can only afford one just now in my mid-30s, haha. I blame Ronald Regan for screwing over working-class citizens. If I had the money my parents had, I’d be driving an EV by now.
(edit: and FWIW I’m in a happy relationship with an adult woman similar to my age)
Yeah but fuck Nissan
Agreed, but mostly fuck modern Nissan. 90s and 2000s Nissan were cool.
I had a 370Z. Basically the same chassis with a bigger engine.
Feels like sitting in a bathtub. It’s got a heavy ass flywheel that makes the V6 feel as smooth as a V8, but with predictable effects on responsiveness. You can cut the fly weight in half and it’s still perfectly good to run on the street without issues.
I traded it in for an Miata NC and never looked back. Sure, the Z has more power, but it doesn’t make good use of it the way a Miata does.
Funny you mention that; I had the opportunity to buy an ND Miata for $5K more. Went with the 350Z instead. Now your comment is making me second guess myself, even though I love how the 350 handles.
It glides through corners so damn well, I can’t possibly imagine it getting any better than this, but you “Miata is always the answer” people always come of the woodwork and make me second guess my decision. The low horsepower figures always got to me. But now I’m thinking that maybe I should have just taken the damn test drive before falling in love with the Z.
Is this revolutionary invention called white paint?
Veeerry reflective white paint. Probably not street legal
Vantawhite
It’s staggering to me the number of black cars being sold in hot countries like Australia. Not to mention just how hard they are to see against the background of a bitumen road.
In some countries, you get a penalty on insurance depending on the car color, with maximum penalty reserved for black cars.
Everyone wants to be Mr Black.
How is it with silver and grey? Do you get a heavy penalty for them too? If it rains, snow and/or are foggy can it be very tricky to see silver and grey cars.
I’m not really sure. I think white and red are the cheapest.
Growing up I remember hearing that red cars were the most expensive for insurance, as owners of red cars had the highest incidence of speeding and dangerous driving.
Red is the cheapest? It’s also a rather nice color, no?
White is fine too.
Heavy rain or snow all that matters is if the lights work!
Source: we get both around here
Okay that’s racistLol. Wouldn’t want to see that applied to people although I can imagine the rhetoric.
This is because the substance artificially reproduces a process known as radiative cooling on the painted surface. A typical example of radiative cooling is a phenomenon where the ground releases heat to cool off.
Nissan worked with the Chinese enterprise Radi-Cool as it specializes in the creation of radiative cooling technologies and materials.
(…)
However, one obstacle remains: the paint is six times thicker than the usual coating on the car body surface. The substance is also more expensive, which would add to the total cost of a new vehicle.
That, in turn, makes it difficult for the coating material to be utilized for mass-produced passenger automobiles.
For this reason, Nissan is looking to commercialize the paint on ambulances and other specialized vehicles as the first step.
…the paint is six times thicker than the usual coating on the car body surface… looking to commercialize the paint on ambulances and other specialized vehicles as the first step.
This is the best part of the article.
After driving ambulance during Australian summers, in the Great Victorian Desert, this would assist so much with operating temperatures. A literal life-saver, if the AC ever broke, also.

With 6 times thicker paint there’s a chance it also wouldn’t rust like a proper Nissan and we can’t have that, now can we
Thicker paint so more chipping resistance? Where do I sign up? 😮
At the… Ugh idk. They all have super thin paint nowadays. Especially the more expensive brands.
That paint’s name…?
A mirror, the car is now mirrorball.
12 degree °C or °F???
°C, which is not bad. Official press release (I think): https://global.nissannews.com/en/releases/nissan-trialing-cool-paint-technology
Neat.
Considering it’s no an American brand I’d say Celsius
Didn’t know Nissan was Scottish

They’re currently working hard for a way to make it subscription.
How big is the difference between black and silver, metallic and non-metallic paint?
It’s surprisingly low. A German institute conducted a few experiments and the most extreme discrepancy was 1.5 degrees Celsius or something.
Yeah, I know it’s an NSX. Deal with it.
What is the relevance here?

Again, what does a somewhat overrated 90s Honda have to do with Nissan’s paint options? And what’s with the tacky body kit?
Especially since it was largely a failure in the racing series it competed which at the time was dominated for years by Nissan.
Weird
JDM internet tough guy shit 🤣
Might be the most interesting thing Nissan has developed in two decades.
They found a very interesting way of selling their hybrid cars as full on EVs where I live. Their e-power stuff are small ICEs working as generators for electric motors that then drive the wheels. Apparently the fact that the wheels get all their power from an electric motor makes it definitely not a hybrid no sir, despite the fact the cars have tiny ass batteries and the single source of power for the whole system is the ICE. Also they somehow have worse fuel efficiency than many contemporary ICEs that cost quite a bit less. I don’t understand Nissan.
A few car companies seem to be doing that. Toyota(?) here are advertising their hybrid vehicles as “self-charging electric vehicles” instead of a hybrid, even though there’s no way to plug them in and not have them self charge.
Where is this?
Neat. Now paint the inside.
so it radiates heat into the vehicle?
How else are you going to entice passengers to take off all their clothes?
Brown chicken brown cow.
Also great for city climate since heated up cars are acting like a heat battery making it significantly slower for a city to cool down once the sun goes away
Ideally there would be no openly parked cars but I guess this is the next best thing
up to 12 degrees cooler
okay but why? What tangible difference is that going to make?
Also is this on the interior or exterior?
12 degrees on roof, 5 on car seat. It’s in the article
Never heard of Asahi.com and not about to click on it. But thanks for getting that information.
Asahi is perfectly legitimate and one of Japan’s largest news organizations.
Just because you haven’t heard of something doesn’t mean there’s anything wrong with it.
I didn’t say it wasn’t.
You said you’re “not about to click on it”, which is implying that you think it is not a good news source.
No it doesn’t, it just means its an unfamiliar one.
Hello and welcome. The purpose of this forum is for people to share articles, and then discuss the contents of the article they just read. If that’s not what you’re here to do, please spend your time elsewhere.
LOL I’ve been here for years, I don’t need a welcome, but I appreciate the sentiment.
I will spend my time when and how I choose, thanks so much, have a nice day!
