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

Mercedes-Benz GL Real Gas Mileage: Pros
Year	Comment
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

2003	4dr Sedan turbocharged 170hp 2.0L I4 5-speed manual FWD	A turbo sedan that got me 35mpg all-highway, and gets 28+ in mixed driving. see full Mazda Protege review
2003	4dr Sedan 130-horsepower 2.0L I4 4-speed shiftable automatic FWD	Great fuel economy my first tank was 28mpg, my second one with my cold air intake installed got it over 30! see full Mazda Protege review
2003	4dr Wagon 130-horsepower 2.0L I4 5-speed manual FWD	The car does get excellent fuel economy- IF you can keep your foot out of it. I rarely succeed in that endeavor- the car is just too much fun to drive, the embodiment of "driving a slow car, fast." see full Mazda Protege review

2003	4dr Wagon 130-horsepower 2.0L I4 5-speed manual FWD	Not too bad, the roof rack hurts it a bit. gets a solid 22-25 driving 70-75 on highway. Does get 30mpg at 60 mph, but that speed will get you killed on California interstates. see full Mazda Protege review

2002	4dr Wagon 130-horsepower 2.0L I4 5-speed manual FWD	I average right around 30mpg with mixed driving, a little highway-biased. I've been satisfied with the overall gas mileage. see full Mazda Protege review

Mazda Protege Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2003	4dr Wagon 130-horsepower 2.0L I4 5-speed manual FWD	Suburban fuel economy is acceptable, at nearly 30 mpg. But on the highway, with the engine spinning well over 3,000 rpm, fuel economy also struggles to crack 30. Many much larger, much more powerful cars achieve better highway fuel economy. Some owners have fitted the fifth gear from the related transmission in the Mazda6 to get more of an overdrive. see full Mazda Protege review
2003	4dr Wagon 130-horsepower 2.0L I4 4-speed shiftable automatic FWD	not good for a small 4 cyl. i have had better economy on the same roads with bigger and simmilar cars see full Mazda Protege review
