Curious to see how the Cayenne does in adverse winter driving conditions. The Rover did great. Should do well, very comfortable with the low temps so far. Has a rest feature on the HVAC that keeps the heater going using the latent heat in the block to keep the interior warm when parked. Works at 28°F for the 45 minutes it takes me to walk the isles at the grocery store or eat at a restaurant.

According to the Owners Manual there is an option mine does not have to run a gasoline fired heater to keep the interior warm for hours until it gets down to the reserve level on fuel. Has settings for separate temp settings and how long to operate unattended. Not sure what the fuel consumption is though.

Talked to my mechanic and he says some 356 and older 911 had the gasoline fired heater option. Says people didn't run them often enough so they got gummed up and didn't work well. Says serviced them at beginning of winter like servicing A/C at beginning of summer now.
