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.
There’s no paint on the planet that will make most of their cars cool.

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
cringe
JDM internet tough guy shit 🤣
Is it white paint?
Twelve degrees what? A degree Celsius is more than twice a degree in Fahrenheit.
State your units, FFS.
1kg is more than twice 1lb (2.2lbs) but 1C is only 1.8F
And 1m is only 12 crayons.
I will assume celsius since the IR image shows around 45 and 35 degrees in direct sunlight.
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.
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
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?
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
Is this revolutionary invention called white paint?
Veeerry reflective white paint. Probably not street legal

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.
Okay that’s racistLol. Wouldn’t want to see that applied to people although I can imagine the rhetoric.
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.
Heavy rain or snow all that matters is if the lights work!
Source: we get both around here
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.
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 typo reverses the meaning by being one letter off.
Lol
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
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.
Why don’t they just make the whole
planeplanet out of theblack boxpaint.I seriously doubt that, tests have been performed comparing black and white painted cars, and the difference was insignificant. The heat buildup in a car is due to the the sunlight entering through the windows.
To add to your comment, ceramic window tint is a night and day difference. My steering wheel, shifter, and all couldn’t be touched after work. I wore driving gloves to get home. With the tint there slightly warm and the AC doesn’t take half the drive to catch up, the car is cool by the first stop light.
Maybe they should sell cars with that by default instead?
Is ceramic tint different from ordinary tint?
Yes. It contains ceramic nano particles that reflect UV without interfering with visibility.
They should install automated blinds like some high end luxury cars have except make them out of that silvery windscreen sunshade stuff instead of developing this paint…
Could you link one of these? All the ones that I can find say there’s quite a bit of a difference
OK I’ll link the danish test, this test is done with 2 cars that are identical, except for the color of the paint:
Konklusionen er altså, at den sorte bil ikke varmes mærkbart mere op end den hvide.
Translation:
The conclusion is that the black car does not heat up noticeably more in the sun than the white.So it does a little bit that you can measure, but not enough to really make a difference.
Det skyldes ifølge Christian Bahl, seniorforsker hos DTU Energi, at bilerne opvarmes gennem ruderne.
According to Christian Bahl senior researcher at DTU energy, that is because the cars are heated through the windows.
(DTU is a well recognized institution for scientific research in Denmark.)Maybe the fact that the experiment was done when outside were only 20-22 degrees made the difference less noticeable? Otherwise I can’t explain why all the other tests I’ve found said the difference was 5-10+ degrees.
This is the t-shirt one I remember.

Sorry can’t find it, all I can find in english are some where the data isn’t clear.
If a white car has brighter interior it will stay slightly cooler, I cannot find a test where everything is the same except the color of the car.
What I can say however, is that the test I saw was performed in Denmark. It’s possible countries with hotter climates may observe some difference?Obviously the main source of heat is what enters through the windows, and how much is reflected out again does have an influence.,
If a white car has white seats and interior, they will obviously not heat as much as black seats and interior.
The white color on the exterior will also reflect more light into the car, except maybe at noon.
Edit PS:
I linked the danish test in a new response.Obviously the main source of heat is what enters through the windows, and how much is reflected out again does have an influence.,
A lot of things seem obvious but turn out not to be, or not as much as I’ve first thought. Hence the usefulness of data and studies rather than mere reasoning.
trick is to paint the windows
Also this is problematic:
12 degrees cooler
But by what scale? If it’s Flaffenfeit, it’s just half an ounce!!!
And an ounce is nowhere close to a decimeter!
I bet Kelvin couldn’t agree more. But to be fair, he started a bit on the negative side. And called everything above that plus.
A bushel of paint should be enough to cover 12 roods.
Dammit, I needed 5.5 qt paint to cover one parking spot
Our European friends are going to need you to convert that to kilometers.
They should install automated blinds like some high end luxury cars have except make them out of that silvery windscreen sunshade stuff.
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.
Anything to not add a cooling system to the ev batteries.
Forget Nissan but I’ll take the paint.
Yeah but 350Z tho
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.
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.
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.
Yeah but fuck Nissan
Agreed, but mostly fuck modern Nissan. 90s and 2000s Nissan were cool.
