Interesting tech to bring down "normal" fuel consumption. I assume it's always the same 4 cylinders that shut down, keep running. I wonder how this affects break in, wear and performance over time. Has anyone driven one of these engines and, if so, are you able to comment on how it performs switching from 4 back to 8 cylinders when needed?

 

My last Audi S8 has the feature. Unless I am looking at the dash display, I have no idea it is running on 4 cylinders.
