The reason the Dodge 4.7 is better than the I4 Turbo is torque...and more importantly, having it available at lower RPM.
Any FI engine that needs boost just to maintain speed on the highway isn't going to be useful for anything - towing/hauling or fuel econ empty.
It's a terrible idea, always was, and won't help lower GM's fleet mileage like they hoped it might. Gamble failed.

I'm not arguing that the engine maybe is or isn't a bad idea...just pointing out facts. The 2.7 makes peak torque (so...near its 348tq peak) from 1,500 through 4,000 RPM. so, that said, the old 4.7 is not quite matching the 2.7's torque output at 1,500 rpm. Maybe below that number, the 2.7 has no power, but heck, 1,500 is basically just cruising rpms. So I think the argument that it has less low end torque than a small V8 doesn't hold true (again...unless we are talking about the off idle rpms...but not sure how much that really matters)
Aside from any long term reliability concerns, the issue is not power...just efficiency.

No...at least not the OLD 4.3 from a few truck generations ago. A far cry from that, but this 4.3 has been around since 2014 or so.
