That makes sense. If an engine needs to run "balls out" to do what it is asked to do, then it may not be much better than a slightly larger less stressed engine doing the same job.

Not sure where the line is with regards to emissions, but in other performance (power and fuel economy) there is usually something to be said for the smaller turbo engines.

Some examples:

Cruze with 1.4L turbo is much nicer to drive than the normal aspirated 1.8L (speaking of the previous gen Cruze)

Fusion with the 1.6L Ecoboost is suprisingly lively compared to the raspy and thirsty 2.5L.

Even VAG's new-for-us 1.4L turbo in the Jetta S is a night and day difference than the old 2.slo it replaced.

But, when it comes to longevity and low service costs, the bigger simpler engines pretty much always win out. And they generally cost less, too.
