There must be something I am missing about driving my 2011 740i in snow. At least I hope that's the case. This car just cannot go anywhere in snow. It's the worst car I've ever had!!!. My driveway slopes about 10 degrees and I have to have a run at it to get up it. The RPMs seem to be limited to about 1K. Surely there must be something better than this to get through snow. What am I missing?
