I have a 2.0L Ecoboost AWD in my 2015 SEL and I'm coming from a 2011 V6 SEL FWD. Can I tell a difference? Yes, I can tell it's not the same V6 engine, more from the sounds of the engine than the performance but I can tell. Does the 2.0L perform? Yes, the acceleration and over performance meets my expectation. Am I saving any gas? No, 850 miles in and I'm avg 22MPG on mixed highway and local daily commute, the same I got on my V6. I realize I now have AWD vs. my old FWD but Ford gives higher MPG numbers on my 2015. Maybe this will improve some over time.
