TrueDelta Reviews the Real Gas Mileage of the Acura MDX

Acura MDX Real Gas Mileage: Pros
YearComment
2014 In addition to trimming the size and weight of the MDX, Acura also reduced the size of the V6 engine from 3.7 to 3.5 liters. Thanks to direct injection the new, smaller engine is nearly as powerful (290 vs. 300 horsepower), and is even a little punchier at low rpm. It can run on three cylinders to save fuel while cruising. The QX60's V6, also 3.5 liters, lacks direct injection and is only good for 265 horsepower. Even though the Infiniti's CVT (continuously variable transmission) can hold the engine at its power peak, this isn't enough to compensate for its power and weight disadvantages. The MDX is noticeably quicker, if still not thrillingly quick. (It can get to 60 mph in about seven seconds.) Then again, fuel economy appears to have been the priority. In the EPA's tests, the 2013 MDX rated 16 mpg city, 21 mpg highway. Infiniti, aiming to top these marks with the JX35 did so by two mpg (18/23). A redesigned CVT shared with the new Nissan Pathfinder bumps the QX60 to 19/25. The new MDX trails the Infiniti by one mpg in the city, but tops it on the highway with a 27 mpg rating--tying the new diesel BMW X5 and impressive for a gas-powered three-row crossover. In real-world suburban driving with an economy-minded right foot the trip computer reported averages from 21 to 23. With a feather-light foot and good luck with traffic lights, 25 can happen. Drive the MDX hard enough to enjoy the snarl that kicks in with the big VTEC cam lobes at 5,000 rpm, on the other hand, and mpg falls into the mid-teens. Highway driving confirmed the EPA estimate. see full Acura MDX review

2012 4dr SUV 300-horsepower 3.7L V6
6-speed shiftable automatic AWD		 Gas mileage is not good. The best I get is around 20 mpg, and use 91 octane as reccommended. I've tried mid-grade 89 octane with no noticable difference but for $1.00-$2.00 per tankful, I'm choosing to stick with what is reccommended. It would be nice to have a front wheel drive only version which would save on gas, but it's not offered. see full Acura MDX 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

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
