So my 2020 Corsair Reserve has a driving mode called Deep Snow / Ruts. It is supposed to be full time all wheel drive and you are warned against driving in this mode on dry pavement. But the owners manual also says (if equipped.) Last Winter I selected that drive mode and it was no different than my Normal mode. Power to the rear wheels dropped off right as soon as I got moving. It appears that you have to order traction lock differentials for this mode to work. In the Winter I use Wet/Slippery mode which does keep 20% power to the rear wheels. I guess I thought that Intelligent All Wheel Drive would not need traction lock differentials. Is the Intelligent part only between the front and rear axles and not to all the wheels at the same time?
