This article is odd. It dismisses up to 30% range loss (250mi to 150mi) by hand-wavingly saying "well, ICEs run less efficiently" (which for modern vehicles means a drop of about 3mpg, so somewhere in the order of 10%).

And then comments that pre-warming requires the engine to idle (on my large SUV that means 0.3g/h, according to the computer) to get the cabin warm, ignoring that in the process of doing so, it warms the engine, thus negating a lot of the efficiency impact of the cold start.

One thing I like about my Audi in winter, if I'm going somewhere briefly? "Residual heat". Tap a button on the climate console, and it uses residual engine/coolant heat and a fan to keep warming the cabin for about 15 minutes with everything turned off, just a fan running (perhaps a small pump?).
