2013 4dr Sedan turbocharged 138hp 1.4L I4
6-speed manual FWD
The fuel economy is excellent on this car as long as you are not on the pedal too heavy. Freeway (70-75 mph) mileage is around 40 to 42 mpg. Rural highway (55-62 mph) 42-46 mpg. The worst mpg i have every experienced is 36.5. This was mostly in town with the AC on. see full Chevrolet Sonic review
2012 4dr Sedan turbocharged 138hp 1.4L I4

Have never got below 37.7 miles to the gallon. I do drive conservatively but even when my husband who drives significantly more aggressive the gas mileage has been excellent see full Chevrolet Sonic review

I had a Choice between My Current Car, a Kia Rio , a Ford Focus and Mazda 3. Between ALL these only the Sonic was a Certified Pre-Owned Vheicle and the others were not. The Fuel economy was ALMOST the Same..but i thought the Sonic had faired A Tad bit better. see full Chevrolet Sonic review

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

It easily gets to 20 mpg on highway. About 18 on mixed driving see full Mercedes-Benz R-Class review

Excellent fuel economy with the diesel, especially when driven gently. Also amazing power at the same time see full Mercedes-Benz R-Class review

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

Much better than expected for a very large and long vehicle. Close to 25MPG on longer trips. see full Mercedes-Benz R-Class review

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

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
