Suburban Dad: 2010 Ford Flex EcoBoost Gas Mileage
The Flex performed pretty well on our cross country move, given that we had two adults and a car full of cargo. Its EPA rating is 16/22 mpg city/highway. The 2011 Flex EcoBoost is rated at 16/21 mpg for some reason. We traveled a total of 2,024 miles over four days. Here’s how each day broke down:
Day 1
- Distance: 550.7 miles
- Travel time: 10 hours
- Terrain: Combination of flat desert roads and crossing the San Bernardino Mountains, and beginning to climb into the Rockies in Utah.
- MPG: 22.8
- Notes: Our mileage was likely affected to some extent by trying to keep two cars together on the journey. Still, the Flex’s cruise control worked terrifically, and the steering-wheel controls made slowing down and speeding up easy, not nerve-wracking.
