Mercedes-Benz R-Class Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2010	4dr SUV turbocharged 210hp 3.0L V6 Diesel 7-speed shiftable automatic AWD	Excellent. We average 27 on the highway travelling at 70+mph see full Mercedes-Benz R-Class review
2009	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	Pleasantly surprised by first tankful. 16.2 mpg in the city. Mostly used "comfort" setting which starts out in 2nd gear and shifts early. With this nonaggressive profile, city driving economy is improved. Premium gives better gas mileage than regular (about 5% on comparable tankfuls). On Comfort setting, no difference in performance is noted. see full Mercedes-Benz R-Class review
2008	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	It easily gets to 20 mpg on highway. About 18 on mixed driving see full Mercedes-Benz R-Class review
2007	4dr SUV turbocharged 215hp 3.0L V6 Diesel 7-speed shiftable automatic AWD	Excellent fuel economy with the diesel, especially when driven gently. Also amazing power at the same time see full Mercedes-Benz R-Class review
2007	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	15mpg city....25 mpg highway....combined is around 17-18 mpg. Not bad considering how heavy this car is. Of course i am very light to the pedal trying to keep my mpg high. Gas is too expensive nowadays so if i don't need to be fast, i am keeping it steady. see full Mercedes-Benz R-Class review
2006	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	Much better than expected for a very large and long vehicle. Close to 25MPG on longer trips. see full Mercedes-Benz R-Class review

2007	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	Pretty poor for a 3.5L. see full Mercedes-Benz R-Class review
2007	4dr SUV 302-horsepower 5.0L V8 7-speed shiftable automatic AWD	F-E is poor because of the weight to power ratio. The vehicle is heavy. With the available power, it is easy to drive faster and to maneuver through slower traffic. Frequent acceleration results in lower gas mileage. see full Mercedes-Benz R-Class review
2006	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	I would probably choose a diesel next time for efficiency reasons - but the additional premium fuel required in the V6 is negligible once the car is paid for....soon now. Very lively engine too. I foresee a hybrid R class type vehicle after 2011... see full Mercedes-Benz R-Class review
2006	4dr SUV 302-horsepower 5.0L V8 7-speed shiftable automatic AWD	only 17 mpg highway see full Mercedes-Benz R-Class 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
