I am currently averaging 20 MPG overall with heavy highway use. For the size of vehicle I think that is rather reasonable. see full Ford Flex review

1000 miles of ownership so far, 21-22 mpg in light suburb and highway driving, 24-25 mpg on 500 mile trip (fuel economy measured by calculating miles driven divided by gallons of fuel purchased). see full Ford Flex review
