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 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 Ford Mustang

Ford Mustang Real Gas Mileage: Cons
Year	Comment
2006	The performance of these cars is not without an obvious tradeoff. In EPA tests, the Mustang GT manages only 15 mpg city, but 25 mpg highway, with the manual transmission. With the optional six-speed automatic, the car can go a mile farther per gallon in the city. The Audi rates a little better in the city, but worse on the highway: 16/23. In my real-world suburban driving, the Mustang's trip computer most often reported averages in the 16-17 range. With a light foot I could nudge the average over 20, and even as high as 24, but what's the point of driving a Mustang GT like you would (or at least should) a Prius? On a 70-mph highway, with the big V8 spinning under 2,000 rpm in top gear, the trip computer reported a fairly impressive (for such a large, powerful engine in a fairly heavy car) 28 mpg. But if you want decent fuel economy in either car, you'll have to ditch the V8. The new EcoBoost four-cylinder achieves 22/31 with a manual transmission and 21/32 with the automatic. The Audi manages similar figures with a 220-horsepower 2.0T four-cylinder engine, but 17/26 with the manual and 18/28 with the automated dual-clutch transmission and the S5's supercharged V6. see full Ford Mustang review

2011	2dr Coupe 412-horsepower 5.0L V8 6-speed manual RWD	V8, 412hp, 26mpg. Who thought those three things would ever go together. see full Ford Mustang review
2010	2dr Coupe 210-horsepower 4.0L V6 5-speed manual RWD	The 698 was a HP390, and got abou 9mph. I oped for the 6 because it has all the power I need and gets real world fuel economy equal to my Escapes. I consistantly get 23 plus in mixed driving see full Ford Mustang review
2009	2dr Coupe 300-horsepower 4.6L V8 5-speed manual RWD	For a 4.6L V8 using 87 octane, 20 city and 28 hwy is not bad. see full Ford Mustang review
2008	2dr Coupe 300-horsepower 4.6L V8 5-speed manual RWD	For a V8, I still get great fuel economy. I average 21mpg with combined city & highway, about 75% city. Only long highway trips, I average 27mpg at 70mph. see full Ford Mustang review
2007	2dr Coupe 300-horsepower 4.6L V8 5-speed manual RWD	Surprisingly, the V8 gets about 23-25 MPG highway driving IF you behave; better than my SUV. The Stang is my choice for my frequent 800+ miles trips once or twice per month. see full Ford Mustang review

2008	2dr Convertible supercharged 500hp 5.4L V8 6-speed manual RWD	Premium fuel is expensive and mileage with a blown 5.4 is not stellar. I would not recommend this as a daily driver but it makes a hell of weekend and evening toy. see full Ford Mustang review
