TrueDelta Reviews the Real Gas Mileage of the Hyundai Sonata

Hyundai Sonata Real Gas Mileage: Cons
Year	Comment
	In fuel economy as well the 2013 Hyundai Sonata has lost an earlier lead. EPA ratings of 24 mpg city, 35 highway, impressive two years ago, can't match the 2014 Mazda6's 26/38 or the 2013 Altima's 27/38 today. The trip computer reported about 25 in my regular suburban driving, a bit over 30 if I engaged in some mild hypermiling, and about 34 on the highway. When mildly hypermiling the Altima for a few miles its trip computer average approached 40. While trip computers aren't always accurate, others have also reported impressive fuel economy from the Altima. The Mazda has a smaller edge, but an edge nonetheless. see full Hyundai Sonata review

What Our Members Are Saying about the Real Gas Mileage of the Hyundai Sonata

Hyundai Sonata Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2013	4dr Sedan 198-horsepower 2.4L I4 6-speed shiftable automatic FWD	With just over 1400 miles so far, it is averaging 28.3mpg combined with the eco option turned off. It has the eco drive option which works well in sustained at speed driving but lags in demanding driving situations. see full Hyundai Sonata review
2013	4dr Sedan 198-horsepower 2.4L I4 6-speed shiftable automatic FWD	The fuel economy is pretty good for a car of this size. I have averaged 36.5mpg (imperial gallon) over the last 37000km. 85% highway, 110km/h and little sitting in traffic. It gets very cold here sometimes so the mileage suffers. In Dec/Jan when it reaches -30 C (or colder), I get about 33mpg and in the summer about 40mpg. My best was 44mpg in the summer and worst was 31mpg in mid-winter when the car was new and not broken in. I keep track of the mileage with an app on my cell phone so the numbers above are exact. see full Hyundai Sonata review

2011	4dr Sedan 200-horsepower 2.4L I4 6-speed shiftable automatic FWD	Average 24 mpg in town and typically get 38 mpg on trips. All in a large family sedan. Uses regular gas. see full Hyundai Sonata review
2009	4dr Sedan 175-horsepower 2.4L I4 5-speed shiftable automatic FWD	The I4 gets about 33 mpg for me in mixed driving. It still has plenty of power at 175 HP and is a quiet smooth engine. This is the first 4 cylinder I have ever owned and so far it has performed well. see full Hyundai Sonata review

2013	4dr Sedan 198-horsepower 2.4L I4 6-speed shiftable automatic FWD	I do a lot of rural driving and the MPG struggles to reach 22mpg. I really expected the mpg to be higher. see full Hyundai Sonata review
2012	4dr Sedan turbocharged 274hp 2.0L I4 6-speed shiftable automatic FWD	Dreadful fuel economy. For long highway drives, the Sonata Turbo can indeed match the 34 mpg EPA rating, but for city driving with A/C, you'll be lucky to get any more than 17 mpg. Even with A/C off, the urban mileage never hits the 20 mpg level. Only 2,700 miles on the engine so far, so this may get better, but the EPA city estimate seems to be pegged too high by Hyundai. see full Hyundai Sonata review
2006	4dr Sedan 235-horsepower 3.3L V6 5-speed shiftable automatic FWD	not as good as some competition see full Hyundai Sonata review
2006	4dr Sedan 162-horsepower 2.4L I4 4-speed shiftable automatic FWD	I expect more MPG out of a modern I4 engine, as compared to my 10-year Accord. see full Hyundai Sonata review
