OK, I understand gaming the EPA. I also understand physics. But will one of you experts out there please explain to me what AFM 2 cylinder deactivation on brief deceleration accomplishes in real numbers?
I am having a difficult time believing this is just another manufacturer/government charade at the consumers expense.
Why not go max on fuel efficiency, shut down the engines entirely and just tow these trucks from point to point.
Note that I am not a proponent of the cylinder deactivation. I remember a buddy's father back in the late 70s had one of those Cadillac setups, and while looking at the all of the technology on the instrument panel, it seemed pretty hard to fathom how it would work.
I do think that if you have a 5.3L V8 and can run it somehow in a V4 mode, their might be substantial savings.
I also think the only way the cylinder deactivation really works is if you can run on 4 cylinders for extended periods of time. If the only time these engines see enough of a reduced demand to run on 4 cylinders is downhill with the wind at your back as you decelerate, then it isn't worth it.
I'd love to drive one of these on a couple of good roads where I know I can "hypermile" the truck and see if I can get substantial 4 cylinder operation.
In any event. I think this is a great selling feature, to choose the diesel
