Averaging 18 mpg. Not horrible, but not great either. With gas prices having doubled since the start of my lease, I try and minimize driving outside my commute and necessary errands. see full Infiniti FX review
2004 4dr SUV 315-horsepower 4.5L V8

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

Only driven around town, mileage 16.6, have never had it on the open road. see full Ford Flex review
