If you're looking for a car that doesn't FEEL like it's FWD, then the 4MATIC will not be the car to get. The balance won't be there due to the constant torque shifting when driving hard, with that 100-0% split default. For bad weather it should be fine, driven moderately. Driven hard it would probably be a handful. I've driven a few vehicles with a Haldex system and they're all similar in that respect.
