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

TrueDelta Reviews the Real Gas Mileage of the Toyota Avalon

Toyota Avalon Real Gas Mileage: Pros
Year	Comment
2013	The Avalon's EPA ratings of 21 mpg city, 31 mpg highway are the best of any V6-powered large sedan. The Azera's numbers aren't too far behind (20/29). The LaCrosse's are (17/27). In our suburban driving we roughly matched the city figure. On the highway, though, we measured about 27. A number of factors might explain the shortfall. With a 70 mph limit, we were cruising well above the maximum speed of the EPA test cycle. Also, every seat was occupied and the trunk was chock full of luggage. Desire better fuel economy? Well, for the first time the Avalon is also available with a hybrid powertrain, specifically the same 200-horsepower (combined) unit available in the Camry. With this engine, the EPA ratings are 40/39. But you'll give up the more effortless acceleration and sweeter sound of the 268-horsepower V6. While the 3.5-liter V6 has changed very little since its introduction in the 2006 Avalon, and lacks the latest technology such as direct injection, it feels plenty strong and is among the best-sounding V6s. At low speeds and in turns traction is the limiting factor. All-wheel-drive would help, but unlike in the Buick isn't an option. The transmission remains the same six-speed automatic Toyota has offered since 2007. It's smooth and responsive, especially in sport mode (offered with the XLE Touring and Limited). If you desire to call the shifts yourself anyway, this can be done via either paddles flanking the steering wheel or the lever. Econ mode makes top mpg easier to attain by dulling throttle responses and quickening upshifts. see full Toyota Avalon review
