TrueDelta Reviews the Real Gas Mileage of the Ford Fiesta

Ford Fiesta Real Gas Mileage: Pros
Year	Comment
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

What Our Members Are Saying about the Real Gas Mileage of the Ford Fiesta

Ford Fiesta Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2013	4dr Sedan 120-horsepower 1.6L I4 5-speed manual FWD	Good for the tight pocketbook. see full Ford Fiesta review
2012	4dr Sedan 120-horsepower 1.6L I4 5-speed manual FWD	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
2011	4dr Hatch 120-horsepower 1.6L I4 5-speed manual FWD	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 see full Ford Fiesta review
2011	4dr Hatch 120-horsepower 1.6L I4 6-speed automatic FWD	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
2011	4dr Sedan 120-horsepower 1.6L I4 6-speed automatic FWD	29 city, 38 highway and i was able to get around 31 is city commute. enough said. see full Ford Fiesta review

2011	4dr Hatch 120-horsepower 1.6L I4 6-speed automatic FWD	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
2011	4dr Hatch 120-horsepower 1.6L I4 5-speed manual FWD	Cruising at 75 MPH for a road trip I got 40+ mpg. Around town I have got around 30 in mildly spirited driving. see full Ford Fiesta review
2011	4dr Hatch 120-horsepower 1.6L I4 6-speed automatic FWD	Best fuel economy in class. 38mpg highway, without complexity of hybrid power train. see full Ford Fiesta review

2005	4dr Sedan 200-horsepower 3.8L V6 4-speed automatic FWD	Thus far, I have averaged 23 and 26 mpg, both times have had roughly a 70 mile highway trip out of 200 miles. Overall, I find this to be acceptable. see full Pontiac Grand Prix review
2002	4dr Sedan 200-horsepower 3.8L V6 4-speed automatic FWD	HORRIBLE. 12-16mpg combined with both city and driving. see full Pontiac Grand Prix review

2006	4dr Sedan 303-horsepower 5.3L V8 4-speed shiftable automatic FWD	Great V8 exhaust note and instant acceleration comes at the cost of about 19 mpg in combined driving, versus 25 with my new car. That is a 30% increase. (the new car is 600 pounds lighter though...) see full Pontiac Grand Prix review
2005	4dr Sedan 303-horsepower 5.3L V8 4-speed shiftable automatic FWD	17-19 mpg in the city. 25 If I drive on the intersate. 30 is possible at 60mph. Most of my driving is in the city. The beautiful v8 makes it impossible to stay out of the gas, but it can run on REG fuel. see full Pontiac Grand Prix review
