Newbie e-Tron owner ( should arrive early May) - but longtime EV owner here.
The Tesla forums are exactly like this thread......cold weather really affects range. It's not just the cold battery. Denser air, less traction, and cabin heat all hurt range. I'm in the "banana belt" of Canada, southern Ontario, but we still see January and parts of December and February below freezing. Without pre-conditioning, short trips can suck up to 50% of range, be it Audi, Tesla, Hyundai, whatever. Longer trips will drive it down to a 25% loss. The only way to beat this is to pre-condition the car's cabin and battery while on a landline. You can also lower the cabin temperature to, say, 18C, 66F, and use the heated seats to save a bit of range.
Every winter the Tesla forums are filled with threads from the Canadian Prairies (gets really cold there), Finland, Norway, and the US Midwest, bleating about their range issues. These are vehicles with 300+ miles (500 KM) range. So, all EV owners are a bit snookered in the winter. Also, Tesla batteries must be warm, or they won't charge. My understanding is that Audi batteries start rapid charging much faster.
Of interest; I put my Tesla HPWC (to be replaced with a J-1772) and NEMA 14-50 plug on Plugshare. I live in a rural area, with limited charging options in almost any direction. Spring/summer/fall I get a few passers by, and customers ( I own an equestrian facility ) use the free electrons. In winter, I usually get at least 6 panicking EV owners contact me to make sure the EVSE is available to them. They've miscalculated their range, due to cold weather, and are going to brick their cars. I tell them to come on in, charge, and have a coffee, and use the wifi in the arena viewing room for an hour or 2. Sometimes I even pop in and join them. If anyone here ever gets stuck in Dufferin County, Ontario:

So, precondition, and plan for a significant decrease in range, regardless of car manufacturer.
