If you told them that, you would be lying. Heating and cooling take power, and lots of it*. That power has to come from somewhere, whether it's fossil fuels, nuclear power, or your rooftop solar panels. That's not even considering what it'd do to your range.

Perhaps a century of living with the IC engine and its loads of waste heat has blinded people to this, but drive your Insight down a long mountain road in winter, and you'll learn :-)


*Unless the car is very well insulated, and the ones I've seen don't look like they have even R-13 insulation, which is way low for house construction.

They didn't say it didn't take any power. Just said it is comfortable to set a departure time or remotely have the cabin already climate controlled before you get in.

Perhaps overhead power lines over major freeways could serve the dual purposes of providing electricity to vehicles, and delivering grid power.

JockoT — That's it. Eastmoreland is right across the street from Reed College, where Steve Jobs dropped out of school. The grandparents lived in the Hollywood district.

Here's the picture Google picked to represent all of Eastmoreland:


Car bodies will start to have more insulation and heat pumps, like the new Leaf.

We should change the title of this thread--it's officially the "Model 3." Tesla lost a trademark infringement suit some time back to Adidas (die Weltmarke mit den drei Streifen).

If your car is sitting in your garage or drive the power it uses to condition the cabin environment actually comes from your charger/mains, so you should still leave with a full charge in the morning. As long as you are connected to a charger it is not an issue.

I'm unclear what you are suggesting.

Most people (here) know that it takes energy to condition the cabin of any vehicle. With conventional vehicles, heat is "free" because of the enormous amount of waste heat from combustion. AC comes at a cost of increased fuel consumption.

In my Prius, AC reduces EV range by about 10%. I would expect a similar impact for other EVs.

My electricity comes from cheap hydro. Conditioning the cabin temperature prior to departure makes it comfortable, and the energy would be spent conditioning the cabin even if I didn't condition prior to departure.

How much does cold weather lower the range of ICE cars?

EV's have several advantages in cold weather - they do not need to warm up. Electric heated seats are far more efficient than heating the entire cabin. And with direct heated defrosters, they would not need cabin heating at all.

As an efficiency nerd, this is a valid topic of discussion.

But from a practical standpoint, concerning the average car buyer, it's not. It just means they have to spend 5 minutes refilling their gasser a little more often than they otherwise would. I doubt most drivers even notice they fill up more in the winter than summer (distance driven being constant).
