When I decided to get the winter wheel set for our 911, I was secretly looking forward to one of those crystal clear days with bright sun, when the roads are dry, the snow is piled on the side of the road, and the temps are well below zero. Knowing a few days ago that we'd likely get our chance this week, I'd pumped up the tire pressure in advance to anticipate the drop in pressure that lower temps would bring (and knowing that I wouldn't want to be pumping air into four tires outside in below-zero temps!) Today was the day (it hit -22 in the early AM); we got to drive the 911 at 15 below! It started up in our unheated garage (at about 8 above) without a hitch, and in that cold dry air it ran great. (One thing we noticed were the creaks and noises from various parts of the car that we didn't hear in warm temps, and I'm having them checked out. I assume some or all are as a result of changes in various materials and gaps attributable to lower temps.)

I went out to dinner last night in South Dakota, and the car I was in made some pretty unhappy noises too. It was -25 degrees when we started the car up after dinner. Be careful out there!

At those temps, rubber, plastic, nylon, etc. are pretty stiff, and lubricants not so slippery.

Yeah ,, that's getting low. Things just don't like to work well at those temps.. Unless specially designed.

Good stuff Avi! Putting that 4wd to use.

Cold enough to cause some shrinking in materials; nothing we can do unless it warms up a bit. Luckily, Porsche tests these cars well below what we're seeing...so the expansion/contraction should be factored into the parts.
Your engine + turbos will be enjoy this cold weather!

My car is lives parked outside. This was this morning at -11F.

This is how your REALLY know it is cold, when the CD stops working

If you don't have to, why would you start any car in cold temps? That is the WORST time to start it! Brittle metals, all fluids are stiff and not effective in lubricating, etc. Put your curiosity aside and leave it alone! (unless you need it for transportation)

Cuz cold starts in the cold are fun :b

These cars are engineered to function in a wide range of conditions; extreme heat to extreme cold.

Glad to see you are having fun! Just wondering if you worry about hitting ice chunks falling out of vehicle wheel wells or frozen ruts while at speed? Does this pose as a potential hazard to the front end or rockers on these cars? From your experience, what is like out there? There are a lot of comments from arm-chair experts, but you sir are living the dream! Can you please share your exhilaration as well as your fears? My hat is off to you! You are the real deal.

I give you all a thumbs up for the bravery of bringing your 911 out in this cold and mess. With that said I will let mine hibernate and remain salt free till the spring. Drive on.
