AAA confirm up to 40% Tesla, BMW, Leaf battery range drop in cold weather.

Probably not a huge issue here as we don't get weather extremes and it's been a mild enough winter.

A new AAA study finds that when the thermometer dropped to 20 (-6) degrees Fahrenheit, range fell by an average of 41 percent on the five models it tested.
You lose 12% just starting it in cold weather.

Fortunately there's no probably about it. There's definitely some range loss in winter here, but 40% would not be the norm at all, 15-20% is about the worst of it.

Think it's important to call out the Irish context around articles like this. The stories of Leaf batteries degrading rapidly in places like Arizona did huge damage to the public perception of EVs, even though they had virtually no relevance here... Lets not have a repeat of that

Low temperatures don't just affect EVs.

Hydrocarbons, CO, NOx, NH3, N2O, CO2 and particulate matter emissions affect air quality, global warming and human health. Transport sector is an important source of these pollutants and high pollution episodes are often experienced during the cold season. However, EU vehicle emissions regulation at cold ambient temperature only addresses hydrocarbons and CO vehicular emissions. For that reason, we have studied the impact that cold ambient temperatures have on Euro 6 diesel and spark ignition (including: gasoline, ethanol flex-fuel and hybrid vehicles) vehicle emissions using the World-harmonized Light-duty Test Cycle (WLTC) at −7 °C and 23 °C. Results indicate that when facing the WLTC at 23 °C the tested vehicles present emissions below the values set for type approval of Euro 6 vehicles (still using NEDC), with the exception of NOx emissions from diesel vehicles that were 2.3–6 times higher than Euro 6 standards.

Well people are more likely to actually see this rather than trawl through some 2,800+ post thread. I've totally given up on those ridiculously long threads...
