Let’s get down to brass tacks. Cadillac’s all-new compact sedan, the 2013 ATS, is not a better car than its target, the BMW 3 Series.

This single, lonely aspect of the ATS is all that matters to trunkfuls of self-proclaimed automotive cognoscenti gathering in car clubs and Internet chat rooms across the country. Their amusement will overflow at the latest challenger to BMW’s decades-long hold on the sports-sedan scepter.

Not so fast. Despite its flaws, the thrill of the ATS’ drive is an impressive feat, and the car itself is a massive step in the right direction. Which is good, because frankly, it has to be.
