I'm getting my winter tires installed today. Living in Western Oregon, our weather is pretty mild. But icy roads are a constant problem and we usually get a couple of good snow storms every year. This is my first full Season with the E tron and was wondering what setting others have found that work best for driving in ice or snow. As I see it, I could start out with six combinations: 1) Coast regen, 2) 25% regen, and 3) 50% regen-- each with Hold Assist 1) turned on, or 2) turned off. Running scenarios through my head, I come up with "25% Regen with Hold Assist OFF, but with Hold Assist on my Shortcut screen. What works best?
