E300 Body Temperatures in Sun vs Color
But - what about red or blue cars? Or silver cars? No one appears to have done a test. Now, I couldn't do a real test on inside temperatures, but where the color of the car affects the inside temperature, the affect has to be basically proportional to the out skin/body temperature. After all, the sun heats it up, and then it convects & radiates to the inside to heat up the inside. Certain other parts of the car, notably the windows and sunroof, are the same regardless of temperature, and no doubt let in a lot of heat there, as well. Anyhow, this is what I found for outer temperatures:
E300 Mercedes, 1PM in bright sun facing NW in a row, skin temperatures of hood:
Polar White: 110-112 degrees F
Iridium Silver Metallic: 118-119 degrees F
designo Cardinal Red Metallic: 149-150 degrees F
Brilliant Blue Metallic: 155-156 degrees F
Black*: 153-154 degrees F
*On the black, I'm not sure if it was plain or metallic black. Also, it was a bit on the dirty side, while the others were shiny clean, so I think that lowered the temperature read some. What really surprised me was how hot the red and blue cars got compared to the white and silver. I guess I expected them to be about halfway between white and black, and silver to be closer to white (although Iridium is a rather dark silver color).
Yesterday I also measured a competitive car I am considering, a BMW 530i:
BMW 530i 12 Noon in bright sun facing SW in a row, skin temperatures of hood:
Alpine White: 123 degrees
Glacier Silver: 130 degrees
Mineral White Metallic: 122 degrees
Black: 160 degrees
I was seriously considering blue or red for my new E300, but with temperatures approaching a black car, I think I'll stick to Silver (as we've had so many white cars in the past).
I know it would be better to check inside temperatures, and that seat color would affect that as well, but this is worth something, I think. If nothing else, it tells you that heat is going to affect darker paint more than lighter.

Color of exterior heating interior would be mainly from roof and doors. Hood not so much nor trunk.
A good test would be to let them both get hot and about same temp...
then start and run AC on some reasonable temp say 73F and see which gets to 73 first.
The white/silver whould cool quicker since heat load into interior is less from the roof and doors.
but main heat load is from sun going thru glass.
Same with color of interior... lighter is better if you live in south.

FYI base prices for 2020 are: E350: $54,050. E350 4matic: $56,550. E450 4matic: $61,550. I believe that is $550 more than 2019 for the E300/350, and $1600 more for the E450, but that includes Blind Spot Assist, Keyless-Go, Electronic Trunk Closer and the new Parking Damage Detector as standard in the base price, plus the $850 12.3" Digital Instrument Cluster is now included in the Premium Package, and yet the Premium Package is now $2,800 vs 2019's $3,150, so base price with Premium Package and 12.3" Digital Instrument Cluster actually goes down by $650. About all other option prices are the same, except Head-Up display which is $110 more, but that's still $540 cheaper than the 2019 model for the E350, but $560 /more/ for the E450.

From the MBUSA website prices for 2019:
- MSRP E300 $53,500
- MSRP E300 4Matic 56,000
- MSRP E450 (includes 4Matic) 59,950
Can you clarify? Thanks.
Again, I apologize for my errors. I will go back and correct or delete them, so as not to create confusion in the future.








Do you have the DOG for 2020? If so could you post. A lot of members would like it as well!
