I agree. Cars aren't effected by windchill, just the real temp. I'm sure it was still pretty cold though!

-65 wind chill or non wind chill is the same i promise you that. I deal with it EVERY day Dec-Apr up here in Minot. The wind will blow under your car and freeze the poop out of your oil pan. I've seen both -70 "real" temp and -70 wind chill temp. Both suck a lot of butt and keep your car from starting. Although at that temp, wind chill or not, your car would have been frozen long before then. Last year i got a picture of my mercedes parked under a bank sign that displayed "real" temp. -58 degrees at 3:12 pm. I'm gonna try to do the same with the Evo.... While trying not to freeze to death. It's been known to happen. You can actualy go to jail up here for not helping someone stranded on the side of the road during winter. No joke.

Its the same to you, but not the car. Here is a definition of windchill: "The portion of the cooling of a human body caused by air motion. Air motion accelerates the rate of heat transfer from a human body to the surrounding atmosphere, especially when temperatures are below about 7°C (45°F)."

Cars don't have body heat.

Then come prove it to me and all the 10's of thousands of people that live up here. I PROMISE you wind chill DOES have an affect on cars. And i'm not talking about while driving. I can leave my car outside for 8 hours, "real" temp is 0, but with a 45 mph wind speed, wind chill would be around -55. I swear on my life that if you haven't started your car in that 8 hours or had it pluged in, your car WILL NOT START. Period end of story. Now... If you had NO wind, you're car will start, but probably will take an extra second or two.

now i'm not one to argue even when i know i'm right, but i hate this stupid @ss state. I work outside on these stupid B-52's all year round and experience the cold like 99.9% of you have NEVER done. This is something all of us talk about up here and dread going into winters. I know i'm right here.

The wind will affect the car but only the heat transfer rate. If the car is the same temp as the environment it won't matter if there is no wind or a 60mph gust. The car can't get colder than ambient temp.

On the other hand if it's -20 degrees outside with a 60mph headwind your car will shed heat faster than if there were no headwind driving down the interstate and may operate at a lower temperature. You would be able to say that the wind affects how quickly the car comes up to temp but at equilibrium the wind doesn't matter.

Takes me back to my heat transfer classes. **shudder**

How long do you idle your car before you go in the morning when its cold outside? I'm going to experience negative degrees this winter with my Evo and I want to make sure I don't hurt my baby.

Again I don't have the manual in front of me but doesn't it say to idle until the temperature needle starts to move then drive? Doesn't have to be fully warmed up just have the needle off of the stop. Someone care to check it out?
