I checked what Ford offers on their ICE vehicles: "The Powertrain Warranty covers components such as the engine, transmission, and drivetrain. It begins at the Warranty Start Date and lasts for 5 years or 60,000 miles, whichever occurs first." So… EV makers are generally 60% more confident in their product's longevity than big auto is. Yes, you're right. The range degradation in cold weather has very little to do with any loss of capacity. It's partly due to having to keep the occupants warm - there's little waste heat in a much more energy efficient vehicle. Partly rolling resistance; partly wheel slip. In fact, all the issues which affect ICE vehicles and people are so used to they ignore - or can ignore because around 83% of the energy they are paying for is totally wasted in normal conditions! The Norwegian government (where very few ICE vehicles are now being sold, and a world leader in BEV adoption) advises citizens to allow for a 20% range reduction in cold weather. Better BEVs allow you to automatically precondition the car on mains power before you leave home. All you do is set a departure time. This warms the battery pack so that your regen works properly from the outset, and so you don't need to waste any energy braking either. And of course it also heats the cabin, steering wheel, seats, and windscreen before you enter the vehicle. I've not experienced this myself (only pre-cooling), but I've watched plenty of videos from people demonstrating this. Surely this is a much more pleasant experience than approaching a frozen petrol or diesel vehicle, where your primary concern is: will the engine actually start? Crazy that they still use lead acid batteries in vehicles, where you need hundreds of amps to overcome huge engine friction in freezing conditions. You'd think that the better marks would have switched to far smaller and lighter Lithium batteries a decade or more ago.
