The problem with this comparo is it lacks objectivity. I have not driven the ATS yet but there is nothing special about the 3.6l engine. There are only two top of the line engines that matter in this class, the N55 and the Audi S4. Not necessarily because of the amount of power but the tq and the broad range in which it's available. In my X5, which is almost 5000lbs, the N55 can do 80mph at less than 2000 rpm and if I punch it responds in an instant, thanks to the 8 speed ZF transmission, same as the F30. Lets not forget that the transmission in the ATS has been determined to be inferior to the ZF transmission.
What I also find odd is the placement of the c350 above the f30, something I have never seen before.
I still have a G 37, looking to get a 335i so I would be the target audience for the ATS, after all I can save a bit by getting the ATS. However I would rather wait for the next G37 than get the ATS. After having driven all offerings of the 335i and the S4, it's tough to pass these two up.
