Nissan Sentra Real Gas Mileage: Pros
YearComment
2014 Aside from some speciality models that cannot be heavily optioned, the Sentra continues to top the rest of its segment in fuel economy, with EPA ratings of 30 mpg city, 39 highway. Well, almost. The new-for-2014 Mazda3 does a bit better with 30/40. Even with its base 1.8-liter engine the Kia Forte doesn't rate nearly as well, 25/36. If you want leather and such you're also getting the 2.0-liter engine, which is rated 24/36. The Sentra's trip computer substantiated its EPA estimates, and then some. On the highway cruising at 65 it reported a two-way average of 47 (up from 40 last year, probably due to warmer temps). In suburban driving the trip computer regularly reported averages of 36 to 37 (up from 32 last year), and on one run to my son's school with a very light foot on the pedals it topped 46. see full Nissan Sentra review

6-speed manual FWD		 With MPG levels of 26 city/ 28 highway (even though you can go as far as 32 mpg highway and obtain an average of 26 mpg on mixed driving with the occasional engine redlining), the fuel economy of this car is pretty adequate. On stock form it will not drain your wallet, even when Nissan has the ECU tuned in the SE-R and SE-R Spec V to run a bit richer than in the Altima. It's no Prius but it's not as bad as, let's say, a modified Mazda rotary engine. Modifications like cold air intake and header will decrease some MPG but the change isn't too drastic either. see full Nissan Sentra 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

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
