TrueDelta Reviews the Real Gas Mileage of the Acura MDX

Acura MDX Real Gas Mileage: Pros
Year	Comment
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

2014	4dr SUV 290-horsepower 3.5L V6 6-speed shiftable automatic FWD	Bought this car because the fuel economy was the same as the Hybrid SUV I was looking to replace. Best miliage is on the highway with AC off at 27 MPG. It gets 23-24 in the city with AC off. see full Acura MDX review

2002	4dr SUV 240-horsepower 3.5L V6 5-speed automatic AWD	I have averaged 25 mpg on the road, occasionally reaching 26-7. Ethanol is bad for it (as it is on all older cars). see full Acura MDX review
2002	4dr SUV 240-horsepower 3.5L V6 5-speed automatic AWD	Best economy in its class. For a 7 passenger vehicle, great hwy mileage. I averaged 22-25mpg strict hwy. 15-18mpg in town. see full Acura MDX review

Acura MDX Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
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
2008	4dr SUV 300-horsepower 3.7L V6 5-speed shiftable automatic AWD	Well, it's AWD, and it's a heavy SUV. As a result, fuel economy is not great. see full Acura MDX review
2008	4dr SUV 300-horsepower 3.7L V6 5-speed shiftable automatic AWD	I have yet to see 15 city/20 hwy, even with 12k on the odometer and not driving it hard. 13/18 is more like it. see full Acura MDX 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
