last time I had to drive my XF in the snow was the day I picked it up, 110 miles home. It did fine...common sense works, if its snowing slow down, leave yourself plenty of room to stop. I have a 'vert, so putting weight in it, isn't an option, the weight would be too far back...but a little weight over the wheels would be fine, very seldom will you be in deep snow, and if you are...well watch that front end, not much clearance for plowing snow...good luck...mine is stored until late March...then the Dragon run.....
