After a heavier snow fall last winter, the OEM Conti's barely got the job done. The TC was ever so annoying that I ended up turning it off as TC can hamper forward mobility if the weather is bad enough. I drive throughout Central to Northern Ontario frequently throughout the year and when the temps are very cold (-40) the snow is a lot harder and the G6 can get through light snow fine on two lane roads. When the temps rise (-10) and the weather is bad, I park the G6 and drive the Durango (4x4) with BFG tires.
A lot of people don't have the patience to drive on snow covered roads, and once traffic starts to build up, they get all the more impatient. Or, it's the opposite, they're TOO cautious and do 20km/h on a clear road and start to brake a mile before their turn. This is when I prefer having my V8 over the V6. AWD traction definitely helps.
Some northern roads that get plowed, don't get plowed by trucks, but by motor graders, whose tires leave marks similar to driving over rumble strips for miles on end. The G6 feels as if it's going to fall apart after a couple miles of this, so again, when I know they'll be out and what roads will be open that I'll have to take, it's the Durango at the top of the list. The longer travel suspension allowed me to travel a touch faster over the grader tread marks on the snow covered roads.
