I started noticing something recently with my Crossfire in cold weather. If I would get out of my crossfire and go shopping or something for an hour or two and come back to the car, it would still be warm inside. I tested this with 3 or 4 other cars, and none of them stayed as warm as the Crossfire.

Is this just a feature or a smaller car, better insulation, or something else? It's just another thing that makes the Crossfire special or me.

 

My guess is maybe the large amount of oil the engine uses holds the heat longer than most. Possibly.

 

Yours is a coupe so that helps.
and it says you live in Southern California, that could help also.
Try a colder state like Illinois, its 10 outside with 13 mile winds
to mack it feel like -5 F. Anyones car at that temp will get cold
in 20 min. Thank god for heated seats!!!

 

That is a very good point mediacritic. Along with that is the layer of insulation on the hood which keeps the heat inside the engine compartment from radiating off the hood.
For all the complaints about rear vision in the Xfire, they do have a lot of glass, so some solar heating could occur in the daytime.

Above all these possibilities is the very real cause of the car's warmth.

These cars are hot!

Actually... I noticed it slightly. I would not say it stays so warm... but definitely not as cold as outside. The interior is literally air tight. I notice when I am driving highway, I will crack the windows and feel my ears want to pop from change in pressure... never had that with any other car. Also, with the amount of fluids the car has under the hood, it should keep a good amount of heat under there; useful for when I turn the car back on and feel nice and warm after leaving it even two hours.

 

Thanks to this forum, I tried the REST feature last weekend with great success. In spite of sub freezing temps, it helped to keep the interior toasty while I ran errands.

 

Yup, the REST feature is NICE! I use it as often as feasible.
As to staying warm, maybe. I do notice that the car heats up quickly & within a few short miles it can become a blast furnace inside. Even with temps below zero (like the past few days; we had a high of 3 in Cent. WI today) the car gets nice & toasty inside.
Ahhhh, warmth..........

 

Look in your manual or search this forum and read up on the REST feature, maybe you are using it somehow and do not realize it.
It is basically a pump that pumps the coolant through the heater system core when it is turned on, using the dash button, with the ignition off. Nice feature, not being one to read instruction books I found out about it on this forum. I have learnt a lot on this forum and hope to learn more, lots of info from smart contributors.
