23 MPG combined won’t win any hypermiling contests, but for a spacious, well-equipped, and genuinely luxurious three-row SUV like the 2017 Acura MDX FWD, it’s a reasonable compromise. This isn’t a vehicle for penny-pinchers, it’s for families prioritizing space, comfort, and Acura’s reputation for reliability, understanding that fuel consumption comes with those attributes.

City and highway performance

The MDX FWD’s EPA ratings are 20 MPG in the city and 27 MPG on the highway. The city figure reflects the engine’s stop-and-go performance, where the 3.5-liter V6 works harder to get the MDX moving from a standstill. The highway number of 27 MPG is more appealing. The MDX shows off its cruising abilities here, settling into a more efficient rhythm, especially if the driver makes good use of the cruise control system.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Acura MDX FWD at $2,500. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and local fuel prices. If you drive significantly more or less than 15,000 miles annually, or live in an area with higher fuel costs, you’ll naturally see a corresponding increase or decrease in your yearly fuel expenditure.

Real-world expectations

EPA estimates provide a baseline, but real-world fuel economy can vary. Drivers who spend a lot of time in heavy traffic may see figures closer to the city rating, while those who predominantly drive on highways might achieve numbers exceeding the EPA’s 27 MPG. Aggressive driving habits, frequent use of air conditioning, and carrying heavy loads can all negatively impact fuel economy. On the other hand, a light foot on the accelerator, judicious use of cruise control, and proper tire inflation can help those numbers get closer to the EPA’s best-case scenario.

How it compares

The 2017 Acura MDX’s fuel economy stacks up against its competitors. A similarly equipped 2017 Lexus RX 350 FWD manages around 23 MPG combined, mirroring the MDX. However, its smaller size might make it less appealing to families needing maximum space. The Volvo XC90 T5 FWD, with a turbocharged four-cylinder engine, achieves a similar 25 MPG combined, but requires premium fuel, which can offset any fuel consumption savings. A 2017 Infiniti QX60 FWD, a direct competitor in the three-row luxury SUV segment, reaches about 22 MPG combined. For buyers cross-shopping these vehicles, the MDX offers generally competitive fuel economy within its class.

Tips to maximize efficiency

The MDX’s 3.5-liter V6 responds well to gentle acceleration. Avoid sudden bursts of speed and try to maintain a steady pace whenever possible. A light foot on the accelerator will significantly improve your MPG, especially in city driving.

Regular maintenance is critical for optimal fuel efficiency. Ensure your tires are properly inflated and that your engine is running smoothly. A properly maintained engine burns fuel more efficiently. Consult MDX MPG across all years to view how different years compare if you’re considering a different model year.

Acura’s Intelligent Variable Valve Timing and Lift Electronic Control (i-VTEC) system is designed to optimize engine performance and efficiency. It works best when the engine is properly warmed up. Avoid short trips when possible as the engine burns more fuel when cold.

Consider using the MDX’s “Econ” mode, which adjusts throttle response and transmission shift points to prioritize fuel efficiency. While it might slightly reduce acceleration, the gains in MPG can be significant, particularly on longer trips. The climate control system is also modulated in Econ mode, so only use it when willing to accept a less aggressive HVAC output.

Reduce unnecessary weight. The lighter your vehicle, the less fuel it needs to move. Remove any unnecessary items from the trunk or cargo area to improve your fuel economy. Check all Acura fuel economy data to see how weight impacts other models’ MPGs.
