Guys,
I know that RRS has 4X4 permanent system. Does anybody know the percentage front rear distribution I mean is it 50%F and 50% rear or it varies? I need more details; what about high speed does rear wheels got full engine power

It's normally split 50/50 between front and rear, just like Disco 3/LR3. Of course, terrain response will adjust appropriately when necessary.

Please do note that this is still a SUV and not a sports car, no matter what marketing says.
