Mercedes-Benz GL Real Gas Mileage: Pros
YearComment
2013 In the EPA's fuel economy tests the Mercedes-Benz GL350 BlueTEC rates 19 mpg city and 26 mpg highway. We observed low 20s in casual suburban driving (a few mpg lower with a heavy foot, a few mpg higher with a very light one) and 25.5 on our trip to Chicago and back (which included some heavy urban driving and 70-mph highways). These numbers don't seem so great, given that the GL350 burns diesel? Consider that the GL-Class is not only wide and tall but also very heavy, at nearly 5,500 pounds unloaded. The gas-powered GL450 is rated 14/19. Our family vehicle, a Ford Taurus X that weighs over 1,000 pounds less than the Mercedes, struggles to crack 22 on the highway. The Audi Q7 rates the same in city driving, and a couple mpg better on the highway. Since the GL350 is almost in another class size-wise, I'm calling this one a draw. Multiply this fuel economy by a 26.4-gallon tank, and the GL350 can go quite far between $100+ fill-ups. Is it really possible to drive the nearly 300 miles to Chicago--and then back--on one tank? Yes it is, with nearly a quarter-tank to spare. (Is it possible to do this without any of three kids needing to stop for a bathroom break? To our even greater surprise, yes to this as well. They were busy watching the $1,950 dual-screen entertainment system.) see full Mercedes-Benz GL review

GMC Acadia Real Gas Mileage: Pros
YearBody/PowertrainComment
2012 4dr SUV 288-horsepower 3.6L V6
6-speed shiftable automatic FWD		 I purchased this vehicle in April of 2012,new with less than 25 miles showing. My wife drives this car to work each day, round trip is approx 30 miles. She is averaging 17 mpg, but on trips I drive and can average 22-23 mpg. I usually cruise the interstate at 70-80 mph. and I do use the cruise control. The mpg will vary but I have seen a high of 25 and a low of 21. Overall very pleased with the ride and comfort, when traveling there are usually 3 adults and luggage. see full GMC Acadia review

6-speed shiftable automatic FWD		 Love the fuel economy of the Acadia... we get 19-22mpg in town.. and 22-26mpg on the interstate. Vehicle speed really affects the mileage attained. We get the best mileage at 55-60mph... it really drops when doing 70-80mph.. see full GMC Acadia review

6-speed shiftable automatic AWD		 Even with conservative driving over long distance, was not able to get close to EPA MPG. In order to get those numbers I have to depart too far from my normal driving habits - wont happen easily, no fun. Especially when the Acadia is so willing to sprint. see full GMC Acadia review
