TrueDelta Reviews the Real Gas Mileage of the Ford Fiesta

Ford Fiesta Real Gas Mileage: Pros
YearComment
2014 The ostensible point of a three-cylinder engine is superior fuel economy. Fewer cylinders generate less friction. On top of this, the Fiesta's new engine is smaller, just one liter compared to the regular Fiesta's 1.6 and the Fit's 1.5. It is turbocharged to compensate for this size difference. The payoff: EPA ratings compared to the regular Fiesta improve from 28 mpg city, 36 mpg highway to 31 and 43, respectively. With a manual transmission, the Honda rates just a bit better than the regular Fiesta, and well short of the Fiesta EcoBoost on the highway: 29/37. But fit the Fit with a CVT (continously variable transmission), and its ratings roughly match those of the manual-only Fiesta EcoBoost: 33/41. In real-world driving, the Fiesta EcoBoost's fuel economy varies widely depending on how much you exercise the turbo. The trip computer reported suburban averages as high as 51.7 mpg, and as low as 28.6. When I drove the car casually but without care to maximize fuel economy, the trip computer reported about 37 mpg. With some care, about 45. Very good, certainly, but some other small cars with less expensive, more conventional engines (such as the Nissan Versa Note, EPA 27/36 with a manual but 31/40 with a CVT) are about equally good. see full Ford Fiesta review

Great fuel economy. Consumer Reports indicated that it was one of the few cars they have tested that actually got better than EPA during their (sometimes high performance) testing. I am getting better than 38 mpg in a mix of city/highway. see full Ford Fiesta review

One of the best combinations of fuel economy and purchase cost you will find in the US. Among the most fuel-efficient inexpensive subcompacts on the market today (though it can be beaten in fuel economy by a number of hybrids that cost significantly more). I've gotten 29-30 mpg in pure city driving, 33-35 in suburbs, and 37-46 on the highway. 5-speed manual has a somewhat lower than ideal 5th gear, which hurts gas mileage over 65 mph (37 mpg was at at 75 mph, 46 mpg at 55-60). Also has a larger than typical tank to go with that efficiency (12.4 gallons), giving you a useful range of up to 500 miles on the highway, and a good 100 miles more per tank than my previous car. Wish list:
  • SFE package with a 6-speed manual
  • "Econ AC" setting that would cool half as strongly and cut out during acceleration
  • auto start-stop
  • the 1-liter ecoboost I've been hearing about for ages but still isn't quite available in the US

Mixed bag. Pure highway exceeds 40mpg w/o effort. Lots of very short trips in town (less than 5 minutes total time) 28 MPG. Part may be the gas blend. The lower the average MPH the lower the MPG. see full Ford Fiesta review

So far I have average 34mpg in 60/40 city/hwy driving. I expect to get more as I learn to drive the automated powershift transmission more efficiently (I have been driving manual for many years). see full Ford Fiesta review

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

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

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

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
