2010 4dr SUV 262-horsepower 3.5L V6
6-speed automatic FWD		 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
2010 4dr SUV 262-horsepower 3.5L V6
6-speed automatic FWD		 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
2009 4dr SUV 262-horsepower 3.5L V6
6-speed automatic FWD		 Only driven around town, mileage 16.6, have never had it on the open road. see full Ford Flex review
