As long as the roads are dry, I'll consider driving mine through the winter. I remember years ago I drove my old new edge Christmas day and on New Years. No salt and no snow that year.
+1... there is no 2015 Performace Pack V6 so I would assume it would be slower than the '14 Performance Pack V6. The '15 is slightly heavier than the '14 and it won't have the suspension and gears the '14 has.
