Aircon is when you open the firewall vent flaps, isn't it?

Silver and white cars are cooler, says study

I have a few 90's, one with a white roof is the coolest inside when they have all been in the sun for the same time, all the others that I have all have black roofs and are quite a lot hotter.

I am on my 3rd black car. Yes, I was bagged by a few people who currently own white cars, but, once you go black, you cant go back...

Yes, when compared to a white car, a black car will heat up faster, but over a longer period of time, the difference will be negligible.

Lets face it, if your car is sitting in 43 degree heat all day, are you really going to notice?

BUT, don't forget, using the same theory, during winter, a black car should be warmer..

Here is a bit of reading, by someone unassociated with Land Rovers:

The interior of a Black car is not hotter than a White car - Bimmerfest - BMW Forums

I have a black roofed defender and had a plain white Hilux,the hilux would get so hot it was unbearable,the defender never has.The defender has near vertical windows but the hilux has a very sloped windscreen that just let the heat in,it was redonkulas how hot that POS got. Pat

How much of the roof of a Defender is lined?

If some of the roof has no insulating lining, then the graph is this article suggests another significant difference between the heat build up in a Defender compared with a car.

So the results of the test quoted below estimate a rise of 5-6c within an hour, -

(The researchers had two cars in the sun for an hour, one black and the other silver, parked facing south, in Sacramento, California. The silver Honda Civic (shell SR 0.57) had a cabin air temperature of about 5-6°C (9-11°F) lower than an identical black car (shell SR 0.05).

MythBuster's results had 10c rise over a full day......

So I go back to my original post.....the difference is neglidgeable and realalisticly would only be noticed with thermometer.

And black still looks the goods

Defenders are not cars.
