8-speed shiftable automatic 4WD, part-time w/low range		 Amazing getting 16-18 mpg around town and 19-21 mpg on the highway is unheard of in a V8 truck this big see full Ram 1500 review
2012 4dr Crew Cab 5.5ft bed 390-horsepower 5.7L V8
5-speed shiftable automatic RWD		 I use to own the v6 and I can honestly say that the Hemi get much better fuel mileage because its not trying to lug around the huge chassis and body. My V6 would avg about Mabye 13 MPG while my Hemi can get about 18 to 24 on good days sometimes even better. see full Ram 1500 review
2011 4dr Crew Cab 5.5ft bed 390-horsepower 5.7L V8
5-speed shiftable automatic 4WD, part-time w/low range		 I am fortunate in that I work from home, and do not need my vehicle to commute to work. However, for a six month period I made a 40-mile round trip five days a week, and averaged 15MPG in mixed urban surface/Interstate driving. This is considerably better than the 2007 Jeep Grand Cherokee 4wd/4.7L V8 the truck replaced (13MPG), and I attribute the better performance to the MDS cylinder deactivation. I have observed 22MPG over a 400 mile trip of combined Interstate and rural 2-lane highway travel with speeds ranging from 60-75 MPH. The truck was unloaded at the time and acceleration runs were gentle to maximize fuel economy. The return trip resulted in19MPG performance over the same route. see full Ram 1500 review

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

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