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
2009 4dr SUV 262-horsepower 3.5L V6

Mercury Montego Real Gas Mileage: Pros
YearBody/PowertrainComment
2007 4dr Sedan 203-horsepower 3.0L V6
6-speed automatic FWD		 It is great for such a big car. 30 mpg is pretty easy for highway cruising, and mixing driving will do 24-25. see full Mercury Montego review
2005 4dr Sedan 203-horsepower 3.0L V6
6-speed automatic FWD		 A large car that gets over 20 MPG in city driving is great. The 29 MPG highway rating is nice, but the car is mainly used as a grocery getter / errand runner. see full Mercury Montego review
2005 4dr Sedan 203-horsepower 3.0L V6
6-speed automatic FWD		 Surprisingly good fuel mileage. 24 city/31 Hwy. see full Mercury Montego review
