There are many reasons fuel economy takes a dive in winter. First is the lower BTU output of the fuel. Second is idling and longer, richer cold starts. You can counteract tires by getting Nokians. They get better mileage than most summer tires for their all weather and winter tires. The advantage of winter is that you can really get aggressive on your grille block in colder temps as long as you're still moving - or you can always throw the heater full blast and crack open the windows.
The only time I could see needing a 4wd is for ground clearance. I've taken my fwd car and rwd truck on the Coquihalla in winter with Nokians and no issues. They're the best insurance policy.
