the 6.2L was also added in to the 2012-14 F-150 Raptors to replace the 5.4 ( optional in 2012)
I was looking at a 2.7l with the big gas tank when I was going to swap out my 5.0l 2011 F-150 for a 2016. Was hoping for much improved gas mileage. In areas with flat ground it would have seen a big jump, but where I live is super hilly, and the reported mileage form my local Ford dealer gained were not worth the change.
I will say I am seeing an Improvement gas mileage with the 3.5l on the Expedition vs the 5.0l in the Scab F-150.
