Replying to my own comment with an update.

The temperature today in my area varied between 9 F at 9AM and 25 F at 3PM. My girlfriend happened to need to drive to several different towns/cities for her work so her total trip was 135 miles. Our Bolt says it has 50 miles left.

I only charge to 90% and just received a new 259 mile range battery as part of the Bolt recall. So the EPA range of my Bolt at 90% charge is 233 miles. If we take the Bolt's 50 mile left range claim at face value (which I have found to be overly pessimistic), then it got 185 miles of range today out of the expected 233, or a ~20% drop in EPA stated range.

So I just don't believe the numbers provided in the linked article. They are completely out of whack with my every day experience owning a Bolt through three winters in Maine.
