We rented a Ford Escape to drive to the Expo last week... it had the EcoBoost feature and we got really good mileage. Not sure exactly, but drove from Florence KY to Ft Wayne IN and back... could have done it on one tank but we stopped to fill up in Piqua OH where the fuel prices were WAY lower... $3.99 compared to well over $4 everywhere else. I think the highest we saw was $4.85. This is for regular unleaded, in case it was not obvious... I would def consider the EcoBoost over the hybrids, as we tend to drive them till they drop, and I don't want to have to foot the cost of replacing those batteries!
