Nissan Xterra Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2012	4dr SUV 261-horsepower 4.0L V6 5-speed automatic 4WD, part-time w/low range	Most people who drove or owned xterra, complain about fuel economy. I say bs: compare it with its true, truck-based SUV competitors - and there are only 3 of them: toyota 4runner and fj cruiser, and jeep wrangler rubicon. Thats all! All others are not to be compared to xterra - they are just car-based SUVs (even new nissan pathfinder is just a car!).rnWhen you compare xterra with correct competitors, you will find that its fuel economy is excellent: my trip computer and calculations show the best economy of 10.3 l/100km on highway at 95 km/h without aircon, on cruise control, on a warm day. My worst is 19.3 l/100km during heavy winter offroading through 3 feet of snow (and it was quite wet snow), using 4x4 low with lockers. From my comparis see full Nissan Xterra review

2012	4dr SUV 261-horsepower 4.0L V6 6-speed manual 4WD, part-time w/low range	I don't see how the fuel economy could be improved, given what the vehicle is. But I can't say that I am happy with the poor fuel economy. see full Nissan Xterra review
2008	4dr SUV 261-horsepower 4.0L V6 6-speed manual 4WD, part-time w/low range	Fuel economy is not the best, I average around 15-16 in the city and 18-20 on the highway. see full Nissan Xterra review
2006	4dr SUV 265-horsepower 4.0L V6 6-speed manual 4WD, part-time w/low range	Although the 2005+ gets better fuel economy than the previous incarnation, it won't compete with the light weight car-based CUVs on the market. If you want the strong chassis and off road performance you will feel it at the pump. Off road modifications like extra armor, dual spare tires, larger tires, and gear don't help either. see full Nissan Xterra review
2003	4dr SUV 180-horsepower 3.3L V6 4-speed automatic RWD	Mileage is terrible for an engine of this size and power output. see full Nissan Xterra review

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

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

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
