TrueDelta Reviews the Real Gas Mileage of the Hyundai Sonata

Hyundai Sonata Real Gas Mileage: Cons
YearComment
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

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

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

TrueDelta Reviews the Real Gas Mileage of the Kia Optima

Kia Optima Real Gas Mileage: Pros
YearComment
2013 Many auto makers are substituting turbocharged fours for V6s because of their theoretically superior fuel economy. The Kia Optima SXL earns EPA ratings of 22 mpg city, 34 highway. The similarly turbo-foured Ford Fusion comes close, 22/33. The most fuel efficient V6, in the new Honda Accord, manages 21/34 without paddle shifters, but 21/32 with them. Trip computer numbers suggest a one-to-two mpg advantage for the Kia in real-world suburban driving--perhaps too close to call since these devices aren't terribly precise. Figure just under 20 with a heavy foot, mid-20s if you resist the temptation, and just over 30 with a very light foot and luck with the lights. All of these figures are with the engine warmed up. In cold weather, fuel economy is in the mid-teens for the first mile or two. An eco mode makes little noticeable difference in either how the car drives or its fuel economy. These numbers don't seem particularly good? Recall that the Kia Optima SXL is a very quick car. You won't find a 274-horsepower sedan that does better without the aid of a battery pack. see full Kia Optima review

I find fuel economy, in mixed driving, to be on par with a V6 of comparable power. I usually get about 24 MPG in combined driving. However, on a recent road trip, I had 32 MPG on one tank. It's perhaps slightly better than the Acura TL I had, but one big bonus: the Acura required premium unleaded. On the Kia Optima, however, the manufacturer only calls for regular unleaded. Over time, that can mean a significant savings. see full Kia Optima review

This is my biggest (and only real) complaint with the Optima. It advertises fuel economy of 22 city, 34 highway. I drive a lot (100 mile round trip daily, with more than half of it being highway miles). Admittedly, I have a heavy foot, but I regularly get about 24-25 mpg combined, with the car in ECO mode. The best tank of gas I ever got was a little over 28 mpg. (I calculate it manually, don't rely on the on-board MPG estimates, as they are always 3-5 MPG more generous than reality.) see full Kia Optima review

I'd recommend this car in a heartbeat. I honestly like this styling even more than the updates they've made since 2012. My biggest cons are the fuel economy and the lack of a manual transmission on any models other than the base model. see full Kia Optima review
