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

2013 4dr Sedan turbocharged 274hp 2.0L I4
6-speed shiftable automatic FWD
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
2012 4dr Sedan turbocharged 274hp 2.0L I4
6-speed shiftable automatic FWD
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
 

TrueDelta Reviews the Real Gas Mileage of the Hyundai Genesis

Hyundai Genesis Real Gas Mileage: Cons
YearComment
2009 While competitors have been switching to relatively small turbocharged engines, the Genesis continues to rely on larger normally aspirated ones. Even the base car's 3.8-liter V6 is nearly twice the size of the Audi's turbocharged 2.0-liter four-cylinder engine. Also, Hyundai doesn't yet offer automatic stop/start. The most significant impact: the Genesis gets much worse fuel economy. With two-wheel drive, the A6 2.0T scored 24 mpg city, 35 mpg highway in the EPA's tests, the Genesis 3.8 only 18/29. Add all-wheel drive, and the Audi's ratings fall to 22/32, the Hyundai's to 16/25, not good. Hyundai has developed a new turbocharged 3.3-liter V6 to replace the 3.8, but it isn't clear how soon this new, more efficient and more powerful engine will be available in the Genesis G80. It won't be available when the car arrives this summer, so most likely the 2018 model year. According to the trip computer, my real-world fuel economy was well above the EPA figures. Only when I drove the Genesis fairly aggressively did the trip computer average fall below 20 mpg. On my usual suburban route it averaged around 23 mpg, and on a 70-mph highway it averaged about 30 mpg. The former was still a few mpg short of the Audi, but the latter was at least as good. If the trip computer is accurate, the fuel economy of the Genesis isn't nearly as dismal as the EPA ratings indicate. see full Hyundai Genesis review

This is my second Genesis. First one was a 2010 4.6L and this has the 6 cyl and it is nearly as quick but gets better fuel mileage. I get in the high 20's on the highway. Used to get 25 to 27 in the 8cyl. This 2012 has an 8 speed transmission compared to the 2010's 7 speed. see full Hyundai Genesis review

Others say they are getting the 18 to 24 MPG claimed. I find that when I do 80% "suburban driving" (strip malls, lights, in/out of car, etc), I get 16 at best. When I am doing 80 on the highway w/ cruise control, I get 23-26. see full Hyundai Genesis review
