Default technical question...

My wife and I are closing in on purchasing that new she's been wanting foe awhile now. I won't say what it is just yet, only that she's undecided on color. It's between black, then silver , then white. I've got her really liking the back, but the concern is the heat. ....not the swirls or paint to keep clean (she already knows about that from my car).
Anyway, here's the question: so just how hot, or how much hotter would the black car get over the silver or white. Factor that the vehicle sits outside for 8 hours (while at work), all have grey/black intereiors and tinted windows. Are we talking 5 degrees difference? 10, 15? post your thoughts, answers, feedback.

Thx,
Greg, Michelle & teh babay.

Id say it wouldnt make much of a difference on the color of the car.... everyone thinks black is hotter... but in the end, the sun beats down on the car just the same.

Invest in some window tint, and a sunshade for the front windshield.

At my last office we had a black SC400 and a White GS400 so for this it's a good comparision. Both had tan interiors. The black car I could not touch after sitting in direct sunlight or had to be really fast about it. The owner would use her skirt or a towel everyday just to open the trunk or doors. The interior was also about 20 degrees hotter on a temp gauge according to our production manager who was courious after putting packages in both cars one day. He had a digital temp gauge for measuring our dryer temps. I can ask him on Monday. He is an engineer and I think very accurate. Both cars are well insulated Lexus.
It was enough for me, my wife , brother and mom to buy light colored cars. My sister bought a black suburban and uses a remote start before getting near it in the summer.
She will not buy another one after summer time youth baseball games.
Just my $0.07c worth

I need to come by Monday, what time is good?

My old car was a dark color, with a light interior, but it got hotter than my silver car with dark interior now. It makes a difference.

Do an experiment with a thermometer in both your black car and someone else's car. Leave it in the sun for a day and see if science answers your question

Light absorption makes a large difference. Go wear a black t-shirt and then a white one in direct sunlight says Mr. Wizard or Bill Nye

Had a blac Acura I brought from Cali to Dallas. First summer here the AC went out -- whatever, short drive to/from work anyway. Problem was that the interior got so hot I could not touch the shifter knob, steering wheel or parking brake. I did not believe the difference between black and white could be so great til I got here where it does get pretty hot.

I sold the Acura and now have 3 cars -- all white!

WHOA! I know the answer (RAISES HAND), well have a pretty good idea. I know the Black will get quite a bit hotter, we're looking at 8-15 degrees difference. I have a laser temp gauge I used on my RC cars and for other general things like track temps, girls hiney's, etc.... . Well the black car (no tint, same car as a beige one) would on average be 12 degrees hotter. The enterior gets super hot on both but if not mistaken it would be like 145-156 in there with the windows rolled up and all.

P.S. Black is still sweeter looking.

Well, Its a matter of physics that will answer this

Energy transfer to where it it is needed, and in the matter of heat, the coolest object will absorb more heat

Heat in your case is in the mode of light, which reflects off objects with certain color pigments so that we see the color of that vehicle

a Red Vehicle reflects red light(and every color under the prism to make red) but absorbs the rest, hence, it absorbs heat in the form of light that is not reflected back

A black car does not reflect any color, it absorbs all of the light, hence, absorbing all of the heat

a white car will reflect white, which is every color under the prism, it will absorb less heat, only the light that gets through the windshield, and hits the interior colors

Eventually, any static object will become the temp of its surroundings, but its a matter of how quickly it can absorb heat, and white absorbs heat less quickly than black does

Remember All colors of light mixed (prisms) together equals white
All colors of on the color wheel (pigments) mixed together equals black

First of all Lilly, ever hear of proof reading before you post? gezz...

As a person who as owned a black and white car now, even purple...

I can say for a fact, the prelude is so much nicer to get into after a long day in the sun. White paint truly does help. So does using a windshield thingy.

If your worried about heat, stay away from leather seats, nothing burns your "goodies" like a seat sitting in the sun all day.

enjoy LOFTR dos'.

I have a white lexus gs and I will agree with H.K's comments. My dad also has a white lexus and I got the best preformance tint and a cheap sunshade. After a days work under houston sun, we both can get in and drive off (though my dad has seat coolers...sounds great in houston), still would advise in just opening the windows or doors for a min or so to help out, but when i get in some of my friends cars under the same condition, open the door and there is no way you can get in.

Kevin is right in investing in good tint, and sunshade though.

And yes black looks cooler.

Depends on how much more important looks vs heat is to you and your wife...and your baby (congrats again)...

thanks for posting, ....i knew that the black was hotter, just wan to know by how much. is it a big difference, does the interior color matter? etc... So far, I know that we are getting leather, (who wouldn't?) and "I" am still leaning towards back, ...even though I said i'd never own another black car, they just look soo darn good!! So, guys, I guess i'll have to let the wifey decide for herself when the time comes.

Greg

oh, and butter, lotrdos was good, now another 3hours to the end.

Nothing wrong with leather in the sun. My leather never burns me or sticks to me. Not sure if it's because of all the tint/sunshade/white car combo but it's definatly not that bad. I hate the hot cloth "itchy" feeling on those cheaper seats.
