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 Volvo XC90

Volvo XC90 Real Gas Mileage: Pros
Year	Comment
2016	The old Volvo XC90's fuel economy was stuck in the early 2000s. When fitted with a 311-horsepower 4.4-liter V8 (last offered for 2011) its EPA ratings were 13 mpg city, 19 mpg highway. The 240-horsepower 3.2-liter inline-six that powered all first-generation XC90s in recent years managed little better, 15/21. The new XC90 is a couple hundred pounds lighter than the original one, and its only engine is a 2.0-liter four-cylinder. Two liters doesn't sound like nearly enough to motivate 4,400 pounds of all-wheel-drive crossover? Well, this particular engine happens to be both supercharged and turbocharged (the former to avoid the lag usually associated with a large, high-boost-pressure turbo) to the tune of 316 horsepower, five more than the old V8. The payoff: EPA ratings of 20 mpg city, 25 mpg highway. The highway figure is lower than that of the MDX (26), but the city figure is the best for a gasoline-powered fancy-brand three-row crossover. The trip computer averages during my week with the new XC90 largely confirmed these ratings. With a light foot in the suburbs I observed up to 27 mpg, a couple better than the Acura. Averages around 23 were common. Make frequent use of the boost and the trip computer average sinks as low as 14 mpg, but drive competitors similarly and they guzzle at least as much gas. Want even better fuel economy? Volvo will soon offer the above engine in conjuction with electric motors that bump total output to 400 horsepower. EPA ratings for the T8 hybrid haven't yet been announced, but they're expected to be impressive. Plus it will be possible to plug in the XC90 T8 then drive it about 17 miles on electricity alone. The downside? The T8 will cost $11,800 more than the T6 even after factoring in a $4,600 tax credit. Fuel savings alone won't justify this bump. see full Volvo XC90 review
