So, I have Nokian Hakkapeliitta R3 SUV studless tires and am using my B9 as a ski rig. This past week, I was traversing up hill in snowy dark conditions 27 degrees with a rutted road with ice in the ruts. Going around a curve the car started to pull off line. I slightly released the throttle just in time as there was not a guard rail, only a ditch on the outside of the curve. Slowly the steering and front tires started to grip and return to the direction my steering wheel intended. This is the first time I have experienced this torque steer effect. Then with less throttle, it released its push/pull and returned to the intended ruts. Maybe the rear end was locked up and this was merely an understeer event. Just scary with 5 vehicles behind me.Traction control can and will cut engine power when it senses slipping in one wheel. So turning it off to spin through some snow seems reasonable, you cannot, however, disable vdc or rollover control so the system is not completely off. VDC will use brakes to try and keep the vehicle pointed the direction you are intending it to go according to multiple sensors in the vehicle.
Are you using snow tires?
The 45/55 split I think works most of the time, but the rear Torsen LSD does cause some understeer uphill in icing conditions. Then, I felt the fronts start to grab hold as the VTD went into the 50/50 mode. Seemed to take about 1 and 1/2 seconds to change from 45/55 to 50/50 through the planetary gear-type center differential and a electronically controlled hydraulic transfer clutch. If you pushed the button, will it change almost instantly or does it take time for the hydraulic ram on the splitter to react?Maybe the cars behind you had no problem because they saw you slide and let off the gas Yes if I wanted to go into deeper snow I would need something with more ground clearance, like my F250, but that would just end up getting me somewhere I really shouldn't be, so I'm gonna stick with the Tribeca as my back up woods ride.

If I lived where it snowed in town I would run studs during the winter. There is nothing that gives traction on ice like studs, nothing.
Yes different drive ratio's don't help. I don't understand why they would want to have more power to the rear tires in slick conditions. Just look at all the mustangs and camero's in the ditch when it gets snowy. Rear wheel drive sucks for winter driving.
