Hope that doesn't happen and good luck!

As to 0-60, I believe any system which splits torque to 4 wheels instead of 2 only is helpful when the amount of powertrain output exceeds the ability of 2 tires to maintain traction while accelerating WOT. This might be more likely with a 235 or 240, such as yours, but seems very unlikely with a 228 or 230, particularly with automatic trans.
you are correct about about the turning issue. I learned this in my 3-series trying to run Pirelli A/S as snow tires with X Drive. They were downright scary in intersections trying to turn in the snow. It was like being in a toboggan. Bad snow tires results in tracking in a straight line. Michelin Pilot Alpin PA4s are the performance winter tires I use. In up to about 6 inches they do well enough handling and steering in the snow, and the X Drive gives that extra traction assist. Agree that X Drive alone won't be enough, you still need a reasonable winter tire but the X Drive gives you a little more choice of that tire IMO.
