I am new to AWD so I have to ask opinions about how Honda system will do in the snow . How does it transfer power if any of the wheels are slipping? Also, if anyone knows how often maintenance is required such as diff fluid changes.This was a rough CT winter and one of the reasons for buying the HRV is getting up my hill to get home. Past couple of years snowfall was too much for the civic. HRV is a good option as 4 x4 pickup at 20mpg does not work for me . Been there with Doge Dakota at 22 gal every 4 days with my commute. Jim
