Awd if far better in the snow than 4×4 and here’s why. I have seen 4×4 in the snow and every time up a hill only 1 front wheel and one opposite rear wheel works not all four and I have seen this many times on 4×4′s getting stuck. A truly good awd system can get all wheels moving and spinning. Part time shift in 4wd really sucks. It’s only for light snow or heavy mud. Put both on a 4 wheel dyno you’ll see the truth. Subaru is proof of this with their awd system.
