BusinessWeek delves into the technology behind the new BMW 3 Series and even has a Q&A with Electronics chief Ulrich Heiden.

All of this is in the name of technological advancement. Of course the new steering set-up is what has most critics railing these days and overlooking these impressive innovations.
