It seems like the 2.7l EcoBoost would be a great motor for the flex, I wonder why they don't have it as an option. I rented a limited EcoBoost AWD flex for a 3000 mile roadtrip, and it was awesome. Best road trip vehicle I've ever rented by far. I say go for it.
The 2.7 is great as long as you don't use it with much weight. Add a FWC or a trailer and it get the same MPG as the 3.5l. The 3.5 is not anywhere close to overkill, it just happens to haul ***.
