Chevrolet Impala Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2012	4dr Sedan 300-horsepower 3.6L V6 6-speed automatic FWD	I got 468 miles on a tank of gas from Greenville TN to Charleston SC then to Myrtle Beach. Very impressed see full Chevrolet Impala review
2011	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	So far so good with E10 Fuel I am getting an average of 27 and I only have 500 miles on it so far. I now have over 3000 miles and just got back from a long trip 1/2 of it hilly. I set the cruise on 67 and let it go averaged over 32mpg by the end of trip see full Chevrolet Impala review
2009	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Averaging 25.0 mpg in mixed driving, very good for the size of the vehicle and the the fact that it is a V6. see full Chevrolet Impala review
2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Fuel Economy beats smaller sized cars, let alone others in the same class. 30mpg is not hard to attain. see full Chevrolet Impala review
2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Its a full size car that gives good performance and still gets 30 MPG on the highway. see full Chevrolet Impala review
2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	If driven carefully, 22-30 MPG around town and 33-36 MPG highway. If you are a sloppy driver, make that 18-20 and 25 MPG. see full Chevrolet Impala review
2008	4dr Sedan 233-horsepower 3.9L V6 4-speed automatic FWD	Mileage averages 23-24 around town and close to 30 on road trips which is quite good considering engine size and power. see full Chevrolet Impala review
2007	4dr Sedan 233-horsepower 3.9L V6 4-speed automatic FWD	15 in town. 30 highway see full Chevrolet Impala review
2007	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Regular gas 28 city 33 Highway. E-85 25 city 28 highway. see full Chevrolet Impala review

2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Less then 25 MPG average see full Chevrolet Impala review
2008	4dr Sedan 233-horsepower 3.9L V6 4-speed automatic FWD	In town mileage is less than 15 mpg. see full Chevrolet Impala review
2007	4dr Sedan 233-horsepower 3.9L V6 4-speed automatic FWD	Only get about 25 mpg on interstate with the 3.9 Active fuel management is a gimmick in my opinion and older GM cars with a V6 I have driven have been better with fuel economy than the 3.9. see full Chevrolet Impala review

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	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
