I'm willing to bet that if you look at the tach on your BWM (or equivalent smooth 4cyl) you'll notice the idle speed is probably 200-500 rpm higher.

I've noticed it in my wife's '13 BMW 328 too. Not all the time, but it's noticeable sometimes while stopped at a red light. More noticeable while the car is in gear and stopped, than just idling in park. It's the nature of the beast with 4-cylinders I think. These new 4-bangers are impressive with the power and fuel economy, but I still hate the way they sound and feel compared to a 6-cylinder or V-8.

I have 2013 Cadillac with 800 miles. It trembles in idle during a red light for example .My dealer tried to fix with a software bulletin however it still has a minor trembling problem that is annoying and makes me wonder do i have a Cadillac or some cheap clunker. I can't believe that Cadillac is not aware or able to fix this flaw with the rough idle .This Cadillac ATS will not compete with BMW , Audi with this problem. The I think has awesome styling and does have a quiet ride but the trembling idle give the whole car a bitter taste.
