letting the car idle to warm up on cold days

[enslow]

Honestly I could see letting it idle for a minute or two where you live, at those temps.

More than just a minute or two.

It's not due to any mechanical aspect of the car that we will idle the car in cold temperatures. It's so that we can defog the windshield. It can take up to 5 minutes to defog the interior windows so that it is possible to see. If you're Sadden, they can even begin fogging up again on the highway if the interior isn't warm enough.

Plus, if you live in the norhtern regions, you're lucky if you can even start the car. You may have to chip ice off the engine itself. I think they even have to find a way to prewarm the accessory belt. There, it's a matter of life or death if your car stalls out. -65 F is cold. And only Sadden can really relate to us what that feels like. I just know I don't want to experience that.

I used to let my car idle for a minute or two back when I had my first car, but it was very dramatic about cold starts. Not that it had trouble or anything, it just put on a big show to let you know "hey I started in the cold, yay me!". It was a Honda curiously.

My truck (or my late Buick) puts on no such show. It just goes. Only difference I notice is that it seems especially torquey when the motor is cold, my guess is because of the extra fuel being dumped in.

I thought I was the only one who thought that. My Bonneville feels quite torquey if I don't warm it up at first. I always warm up my car in the mornings before school. Not for the engine but for myself like some people have said before. I usually let it idle for about 8 mins, give or take a few. It fully defogs the windows and removes any ice on the front or back ones. And I have a nice warm ride to school. But that's just personal preference.

Sometimes you think your warm enough pull a 0-60 on the highway and find out otherwise.
