" Do Cars With a Dark Interior Really Get Hotter in the Sun? "
The difference between dark and light interiors might not be as substantial as you think.
There's a common belief that if you live in a warmer climate, you should opt for a lighter interior when buying a car because that will help to reflect ultraviolet rays and keep you cooler. But how much hotter are dark interiors vs. light interiors?
"Consumer Reports' test engineers took two cars, one with a light-colored exterior and light-colored interior, and the other with a dark exterior and dark interior, and parked them both outside," says Mike Monticello, CR's road-test manager. "The temperature initially inside both cars was 78° F. Within an hour, they were both over 100° F. The darker car did get a little bit hotter, but only by a few degrees. And that was only after an hour, so think about how hot these cars would get for an even longer period of time."
