TrueDelta Reviews the Real Gas Mileage of the Kia Optima

Kia Optima Real Gas Mileage: Pros
Year	Comment
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

Year	Body/Powertrain	Comment
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
2011	4dr Sedan 200-horsepower 2.4L I4 6-speed shiftable automatic FWD	High 30s on the highway and 29-30 overall with a lot of power. Active eco. setting for better economy. see full Kia Optima review

Kia Optima Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2012	4dr Sedan turbocharged 274hp 2.0L I4 6-speed shiftable automatic FWD	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

Audi A3 / S3 / RS3 Real Gas Mileage: Pros
Year	Comment
2016	For a car that can get from zero to 60 mph in under five seconds, the Audi S3 can be quite economical. The tested 2016's EPA ratings were 23 mpg city, 31 mpg highway. For 2017, the S3's ratings have fallen to 21/28 for no obvious reason. Maybe the updates pushed the car into a higher test weight class. I doubt the car's real-world fuel economy has changed. I observed 25 mpg in suburban driving (with a light foot) and nearly 30 mpg on the highway. Despite its more powerful engine, the Mercedes-AMG CLA45 scores even better than the 2017 S3 (if not quite as good as the 2016): 23/30. see full Audi A3 / S3 / RS3 review
