See attached info-graphic about the impact of cold weather (from 2014-01-16).

I've also read that some BEVs keep the heater on in the battery compartment even when the car is parked (in cold weather), which means it will slowly drains the battery if you leave it unplugged. I think EVs are great in general but they do have a range problem and that gets worse in cold weather.
How the hell do they get to a 19% reduction of range on an ICE car? Back when I was still measuring fuel consumption on my diesel cars I never noticed any measurable changes in fuel consumption between summer and winter. Perhaps the authors of the website let the ICE engine idle for 10 minutes and then drove 5km or so. There is no sensible way to explain it otherwise.

There is no sensible way to explain it otherwise.One factor is that cold air is denser so the air resistance increases, you might have worse road conditions (especially with snow) and lower tire pressure, and electric powered heaters like seat heaters and such also affect an ICE. They also mention some factors at the bottom of the graphic that indicate major factors are cold start and excessive idling/warmup.

It seems the testers let the cars run idle for a long time and then drove a very short distance. Stupid pro-EV websites Do they really think we're all idiots?
When I commuted a lot with my cars I never found a large variation. The variation was around 2% when driving the same route and filling up at the same gas station for thousands of kilometers. What did impact fuel consumption measurably where switching to a higher quality fuel and having eco-tuning on the engine.

Also, the increase in energy consumption running the AC is identical EV or ICE, so in the context of the EV vs ICE argument, AC is a non-issue at all.6.4 kW is ~ 1/3 of the power needed to move the car, I wouldn't call it a non-issue, EVs (unlike ICEs) have an already poor range and this makes it even worse.As I keep pointing out, you are using absolutely worst case scenario numbers (again), and not real world number; nor are you considering the equivalent performance of an ICE car.
Let's do the math. If the efficiency of an ICE were ~ 45%, and to move a car on average you need say 18 kWh/100km, it means an ICE dumps as heat 0.55*18/0.45 = 22 kWh/100km, even 1/3 of that is plenty enough to heat the cabin.

More like 30%, or so, with any luck.
Take a look at this. Quite an analysis they have done on the entire vehicle: https://www.fueleconomy.gov/feg/atv.shtml

I think the point is that the very inefficiency of the ICE engine means that the wasted energy is available
free, & using it to heat the car interior means that energy doesn't have to be found from the engine's mechanical output.
Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) can have a thermal efficiency that exceeds 50%
But produce many more toxic side product and more finedust which kills people.
Diesel iafaik per definition a lower quality fuel from the destillation process
So what causes the extra pollutants if diesel is equally clean as petrol?
Combustion temperature?
