Default Efficiency?

A gasoline vehicle burns the fossil fuel directly inside the vehicle, whereas the electric vehicle needs to get electricity from a power plant that is only 33 percent efficient at converting a fossil fuel into electricity. That would seem to indicate that, in terms of converting a fossil fuel into energy to power a vehicle, the gasoline vehicle would actually be more efficient. Maybe an energy expert can explain it better.
I came from Minnesota to the villages last year and here the winter was described as harsh because we had 2 nights in the 20F range.

In Minnesota and north there have been several winters where 35 or more days in a row it never got above freezing. And several winters it never gets above 0F for a week or more.

When you go out to your unheated car when it is -20F it will barely turn over because the battery is so inefficient at that temperature.

I have a friend with a Chevy Volt and it will not even go 20 miles in the winter on cold days. And they keep it in a heated garage. They will not park it on the street or travel more than a few miles from home when it is cold because the fear getting stranded because the batteries might get to cold while parked at the store, movie, show, restaurant etc…
