What Our Members Are Saying about the Real Gas Mileage of the Mercedes-Benz R-Class

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

Mercedes-Benz R-Class Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2007	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	15 mpg average. Not good 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

What Our Members Are Saying about the Real Gas Mileage of the Hyundai Azera

Hyundai Azera Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2008	4dr Sedan 263-horsepower 3.8L V6 5-speed shiftable automatic FWD	30 mpg on the highway under cruise control. 21 mpg overall in the city. see full Hyundai Azera review
2008	4dr Sedan 263-horsepower 3.8L V6 5-speed shiftable automatic FWD	Variable valve powertrain delivers very good city mileage (16 mile trips per day @ 22mpg) and above expectation highway (425 mile trip at 32mpg). Highway is usually above 30 even in slow interstate traffic in the city. see full Hyundai Azera review

Hyundai Azera Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2008	4dr Sedan 263-horsepower 3.8L V6 5-speed shiftable automatic FWD	The gas mileage is respectable but lower than most cars in the large sedan class. see full Hyundai Azera review
2007	4dr Sedan 263-horsepower 3.8L V6 5-speed shiftable automatic FWD	Poor mileage. see full Hyundai Azera review
2006	4dr Sedan 263-horsepower 3.8L V6 5-speed shiftable automatic FWD	While stellar fuel economy can't be expected in a 3600 Lb car with a 3.8L V6, it does leave something to be desired, averaging somewhere between 15-17MPG in a mix of city and highway driving. Pure city driving returns closer to 13-15 MPG (although the peppy engine may have something to do with that). The car would really benefit from a 6th gear. see full Hyundai Azera review
2006	4dr Sedan 263-horsepower 3.8L V6 5-speed shiftable automatic FWD	short distance driving exhibits just fair fuel economy see full Hyundai Azera review
