TrueDelta Reviews the Real Gas Mileage of the Mercedes-Benz GL

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

2007 4dr Sedan, ext. 382-horsepower 5.5L V8
7-speed shiftable automatic RWD		 Since my driving is about 50-50 city and highway, I average about 20-21 mpg, using premium fuel. All highway is 29-30mpg and all city is 14-15mpg. see full Mercedes-Benz S-Class review
2007 0 While on long trips at 70-80mph I average 32mpg around town it never goes better than 24mpg. Easy on the pedal sure shows results but fully loaded the thing shifts like a two door sports. see full Mercedes-Benz S-Class review
