The competition: BMW 3-series
General Motors has been promising to build a BMW fighter for as long as I have been covering autos, and this year it may finally have succeeded. Whereas the old GM would have recycled an existing platform for this compact luxury sedan, the post-bankruptcy company has created an all-new rear drive setup with generous amounts of aluminum to hold down weight. The design is more elegant and refined than on earlier Cadillacs, and power will be ample. For BMW, making a better 3-series is like redesigning the Eiffel Tower: It is hard to improve on perfection, and you risk offending traditionalists when you try.
Advantage: ATS, for novelty.
