Thanks for posting. I sent the link to a close friend who's a Tesla owner.

Sounds almost as bad as our old VW bus. We finally had a gas heater put in that ran off the gas tank. Worked great but was a thirsty bugger. You could almost watch the fuel needle go down.

Thanks for the heads up. I never got clear from the article whether the issue was a Tesla design problem or it’s just impossible to run heat in an EV at extreme low temps?

I remember when I was first married we went through a spell of -40 degree weather in Detroit. Biggest problem was you couldn't keep a battery charged overnight. Royal PITA.

Thanks for the heads up. I never got clear from the article whether the issue was a Tesla design problem or it’s just impossible to run heat in an EV at extreme low temps? Probably both. Batteries lose capacity in the cold. Don't know if there's some magic in a Tesla to help overcome that. Seems it may have something to do with how you're charging it (a Tesla-approved high powered charger or just into 120 V home A/C). I do know that Ford offered an electric Ranger when I worked there in the '90s with a sweetheart lease deal for employees that had a range at the time of about 110 miles. Living 10 miles from work it might have been attractive if it hadn't been for living in Detroit when that range might drop 40% and you had to go anywhere other than back and forth to work at all. Also, a normal gas/deisel vehicle gets its cabin heat from the engine which would have to come off battery power in an EV. In Saskatchewan in the middle of winter and the middle of nowhere, it might add up to no heat in the cabin.

I was astounded the other day to read that Tesla had delivered nearly 1 million cars worldwide last calendar year. (936,000, to be precise.)

My ex-wife's family in Minnesota told me they used to hang work lights with high-wattage bulbs in them under the hoods of their garaged cars to keep the batteries and oil pans warm.
Minnesotans here: true or false?

Possible, but more common was the so-called head bolt heater, which kept oil warm enough to allow the engine to turn over in the morning more easily.

All of the above. Anything to keep the engine block unfrozen.

Yeah, plug in block heaters are the schizz in cold environments. But they're also a kind of obscure option for most. They're particularly important with diesels since the vaporization temperatures of the fuel are kind of high (10-20 degrees F). If the fuel doesn't vaporize, it don't burn. When I was with Volvo I did a lot of travelling to check out customer fleet engines and operation. One of the most interesting was a fleet in the mountains outside of Denver. They literally kept left the engines running in their trucks 24/7 for maybe a month at a time, whether the place was manned or not, because it got so cold, if they shut the engines down, it would take a full work day to get them all started again.

Before we got block heaters, on really cold nights we would just put some cats in the engine compartment. Give them a fluffy blanket and some food and they would settle right in, and gratefully so. Had to remember to remove them prior to starting the car, however.

In Alaska where I grew up all cars have block heaters and many of the 18 wheelers run 24/7 through the heart of winter. In Fairbanks when it gets down to 40 below(or often colder) one old timer trick was to put some self light charcoal briquettes in a paint roller pan and slide it under the oil pan.

And of course the mandatory case of ether bombs in the back seat. It always seemed like a nasty wake up call for an engine peacefully at rest.

I reckon that fuel injection, computerized combustion mapping and synthetic oil have made our cars a lot more startable in winter.

Still comes down to the basic physics of the fuel and batteries. Fuel injection and computerized combustion mapping go a long way to making pollutant emissions lower and improving overall reliability, but in the end you can't fight physics.
