A question of colour...

Postby DaveS » Sun Jun 18, 2017 12:17 pm

Hi all,

A question re vehicle colour. Obviously I'm aware that a white or light vehicle will reflect the heat better than a dark colour, but how much difference does this make in practical terms? I've been looking into painting my Sprinter 4x4 (its currently white, and I want to get away from the delivery van look), but wondered whether I'd regret it later if the internal temperature rises, especially during the summer in Europe, as we've not got aircon!

Any thoughts appreciate!

I would keep it light if I was you, a dark coloured metal box gets very hot when left out in the sun. I once owned a black 4x4 that was like an oven in the summer.

Hi Dave. We've not noticed much difference in temps with ours been not white. Saying that, I don't think we'd go any darker with any shades in the future.

I remember the effect being quantified on Mythbusters:

"A fan wrote in and asked a follow up question: “Does the color of a car affect the way it heats up?”. The MythBusters used two identical cars, one black the other white and left them both out in the summer heat with thermometers in both. By mid-afternoon the black car had heated up to a temperature of 135 °F while the white car topped off at 126 °F, almost 10 degrees cooler." (About 5 Deg C).

I recall the test was done in absolutely searing heat and in such a way to maximise the effect (windows closed etc). The effect would be much less than this with less extreme exposure, anything other than pure black, and with well-insulated campers: so I'd guess that in real-world-camper conditions the effect would barely be noticeable.

Go nuts...

Thanks guys. We're using it shortly for a long weekend (in white still!) and will have a ponder whilst we're out in the sun (hopefully). Cheers.

Keep it white, just add big graphics. Cheaper and if you're aiming for re-classification it all helps convince the DVLA (or it used to..I'm not "up" on the latest directives)
