    What about winter? Dark color cars are much warmer to get into after sitting in the sun a few hours than light colored cars. Opposite in the summer. Net net.

      Except the sun doesn't shine much in winter.

          So that begs the question, do people with darker colored cars and larger rims drive their cars more 'aggressively?' I don't know the answer, but I am sure there is a study somewhere that addresses the issue.

            My guess is this study has a lesser factor on M3 since the roof is glass, not painted steel

              With Tesla, I doubt it makes any measurable difference at all as the cabin is all glass anyway. So there isn't any difference between a white and a black car from the window sills on up.

                  Maybe it only impacts police behavior.

                    Hey @ModFather, have you run across any similar study concerning interior colors? As has already been mentioned, I'd think that the Model 3's glass roof would negate most of the effects of the exterior color story, but I'd also think that there would be a non-trivial difference with a white vs black interior...

                      I'm sure the exterior color makes some difference when you have a huge roof panel...but all Model 3s of any color will have identical top surfaces: all glass.
                      If anything there may be a different between black and white interior color. But Tesla's special homebrew tints and filtering will probably filter most of the IR out.

                      I wish that were the case. The Premium package lists the all glass roof as a part of what you get for your $5k.

                      The metal roof is still only a small percentage of the roof. Even without the premium glass roof, most of the top surface will be glass.
