I know, I was thinking maybe 1-cyl. down hill but, no...then you would want engine braking, so maybe 1-cyl. in the drive-thru ... who thinks of this stuff ?...but, anyways still better than no V8 offering and boosted V6s.
Why do I want 1-cylinder to run.....? This must be when idling or parked. I doubt you'll see any vast fuel mileage difference in this version vs. their strictly 4-to-8 ones. All this DOD & AFM stuff is getting stupid now.
Then why does the current AFM go to 8 when idling? Why not 4? That would also work when creeping along. That would be the logical thing to do in traffic to keep the A/C working and the battery charged up.
I'm going to wait to pass judgement until we see how it works. At least the theory behind it sounds better than how AFM works, at least. Cycling which cylinders are turning on and off should help reduce coking.
