Mercedes-Benz R-Class Real Gas Mileage: Pros
YearBody/PowertrainComment
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

2008 4dr Sedan 110-horsepower 1.6L I4
5-speed manual FWD		 From a 17mpg average Chevy truck to NEVER getting less than 29mpg city, need I say more? Well okay, how about 37mpg on a freeway run. I have only got 13000 miles on the vehicle, and can imagine the fuel economy will improve still more. see full Kia Rio review
