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.
Windshield screens are the low-tech but far more effective method of keeping a car’s interior cooler, typically by at least 20F when it’s really hot out. Slightly inconvenient but unlike this paint, a windshield screen will actually make a difference.
I don’t care about your cage’s interior temperature. Until we can ban cars from cities I’d welcome such paint, because all those shit heaps of cages standing on public space still end up heating up the places around them, further inconveniencing everyone else even more.
You realize the emissions saved from reduced AC usage would also reduce the heat island effect, right? Sun visors like this are good for public spaces.
Also, it’s more environmentally friendly to have people use visors than repaint their whole car.
That still does not make me care about your cars interior temperature.
That’s okay, you seem pretty simpleminded so I don’t exactly expect you to understand the issue. I understand the anti-car sentiment but you’ve clearly gone off the deep end yet you still seem to think it matters to other people whether you care about issues like this.

Projecting much? Love the insults btw. Really drives your point forward.

You seem to care a lot. It’s also again projection and highly ironic since you were the one who apparently thought people care about your car’s interior temperature.
You seem to care a lot.
I think you’re confusing my care for the issue as me caring for you. It’s too bad you can’t even be bothered to make some of your comment relevant to the discussion.
Do they? I mean yes, because the ICE engines just constantly dump a ton of heat out, but does a parked car? Is there data on that?
Yes, just like “rock / gravel gardens” or whatever you call them in English, which are now banned in a lot of places for one reason being that exact same phenomenon of contributing to the urban heat island effect. They soak up the heat from the sun like a battery and then slowly release it into their environment, keeping it warm. It’s super obvious as a pedestrian.
Mythbusters did an experiment with a black car and a white car hitting in the sun. The black car was 12 degrees Celsius hotter. Claiming that the paint makes no difference is such a weird take. I thought this was common knowledge as well as many people I’ve met avoid darker colours in summer and such.
Speaking of huge and inconvenient, if you’re a cheapskate, just get a car cover. Always helped my motorcycle.
I bet the interior of your motorcycle was WAY cooler after that.
It was! Also, the exterior wasn’t too bad, either
Summer was hard on me in my teenage goth years.
Can’t really get many light shades of black.
I think i’m in love.
What’s the cost (financial and environmental) of repainting a car vs using a windshield visor that’s at least twice as effective at reducing heat? Painting a car with this stuff would cost thousands of dollars compare to $20 for a visor.
I’m not talking about repainting anything, why are you moving the goalposts? Just buy a white car AND use a visor, what’s wrong with that? And in the future, if this stuff is actually good, maybe all cars can come already painted with it?
Wanna know how you’re right? Look at the FLIR photo above and note where the heat is at its highest
Twelve degrees what? A degree Celsius is more than twice a degree in Fahrenheit.
State your units, FFS.
I will assume celsius since the IR image shows around 45 and 35 degrees in direct sunlight.
1kg is more than twice 1lb (2.2lbs) but 1C is only 1.8F
And 1m is only 12 crayons.
Nissan invents white paint
If it’s like this stuff then it’s more than just white paint.
I was hoping I’d see nighthawkinlight in the wild here.
Only reason I’m here lol
If it’s like that stuff then they didn’t invent it.
Well, they would have invented the specific formulation they’re using. I’m sure it’s not exactly like this but I wouldn’t be surprised if it’s the same concept with microbeads.
No one invents anything totally new. It’s all adding on to what others have made in the past. Nothing has ever been created from scratch.
so, what temperature is inside the car? scientist have found out its actually the glaspanes that makes cars hot, just saying.
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
can i paint my house with that?
There’s already a 98% paint, not that cheap last I checked though.
Nanoparticle roof shingles are a thing and they really work well
Nissan also detects you having sex in the car and phones the info home.
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.

You know, we can use vision ai services to do that now, dang yo time flies
so you’re suggesting that it’s feasible to use a video stream from the car to read lips by, what, paying out of pocket to send the video stream over the built-in cellular? Possible, sure. Then receiving it at a datacentre and running one of the most computationally intensive algorithms in existence on the video stream, 24/7? Or at least only when I’m using the car? so the datacentre is processing presumably tens or hundreds of thousands of these all at once, so at let’s say 5mbps per video that could easily be multiple terrabits per second of bandwidth, consuming megawatts of power in order to spy on people in probably the least efficient and most expensive way imaginable, and all to determine that I said I like coke rather than pepsi so the car company can receive $0.01 in selling that to some ad company?
Is that scenario possible? Yes. Is it happening? I am certain that it’s not in any rational company. The same line of reasoning applies to listening to your phone’s microphone or camera, except there you’d also notice your phone getting hot and the battery dying in an hour or two.
The GPS thing is feasible. I don’t know if they’re doing that but they could. As soon as you mention transmitting video feeds or cloud AI you’re in conspiracy territory.
||Now, Tesla’s on-device AI processing using the driver’s power bill to analyse video on-site and only send the tiny results into the cloud… is very different. ||
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.
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
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?
My wife’s going to be pissed when she gets that call…
Why don’t they just make the whole
planeplanet out of theblack boxpaint.Forget Nissan but I’ll take the paint.
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.
Yeah but fuck Nissan
Agreed, but mostly fuck modern Nissan. 90s and 2000s Nissan were cool.
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.
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.
Anything to not add a cooling system to the ev batteries.
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.
They’re currently working hard for a way to make it subscription.
As someone living in Wisconsin with salty road winters, I’ll say that Nissan’s reputation is mostly trash here based specifically on their paint

Also being the Alabama of the North.
Is it white paint?
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.
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!
