White vs Black affect on Car Temperature

Stumbled on this RACQ research

Curiously, the temperature difference between black and white car colour is comparatively minimal. Even window tinting is less than you might expect.

So, if concerned with air-conditioning a darker toned EV - not really an issue.

White vs Black affect on Car Temperature

Post by Electrocycle » Thu, 02 Feb 2012, 22:21

having had the same and similar model cars in black and white, as well as tint vs no tint, I can say it makes a huge difference.

After leaving my white ute in the sun all day the cabin is hot, but not massively uncomfortable, and cools down after a bit of driving.

My black Silvia needs to be left open for a while before driving if it's been in the sun, even in winter. It could seriously cause heat stroke!
Everything inside heats up, so it takes ages for it to cool down.
You can feel the heat radiating off the inside of the roof, whereas with a white car even the outside surface is usually only warm to the touch.

3.1 degrees difference after a couple of hours is still a noticeable increase!
Sure it is the difference between very hot and very hot + a bit more for good measure.   Image

Hey Mr Electrocycle,
I think you might be comparing apples to oranges.
Your Silvia has much more glass at a very different angle to your ute.

I only find the tint makes a difference to my right arm Image
So the short answer is NO but the long answer is YES.

I have also compared two Silvias, and other utes.

I guess a lot of the difference I've experienced might be air temp vs surface temps inside the car.

A white car with tinted windows and a sunshade on the windscreen will cool down to a comfortable temperature as soon as you start driving, and the steering wheel, seats, etc will not be super hot.
Even in the black Silvia a windscreen sunshade means that the steering wheel, gearstick, and dashboard are only warm to the touch, vs burning hot.
Surfaces take a lot longer to cool down than the air.

I used to have a mini moke years ago and when i had the seats redone i had them done in white instead of the black they were. As this car had no roof the sun would beat straight down on the seats. Now with the white seats i could just hop on the seat and it would be only warm now when i did the same when they were black it would allmost burn me Image
