[quote=MyPart;166576]I know that in many acceleration scenarios in my 08 FEH, the computer will put the engine at 4000 RPM and hold it there. Looking at the torque curve, I think it's obvious that Ford programmed and engineered for this scenario. By having the eCVT, Ford can put take advantage of the engine's most efficient (and possibly the more clean) power zones.[/quote]

What makes this situation more interesting is that hypermilers such as GaryG attempt to keep the RPMs below 2000 as much as possible for best fuel efficiency.
