23 MPG combined is acceptable for the 2020 Acura MDX FWD 3.5L 6-cyl, but fuel economy probably isn’t the main reason people buy this Acura. It’s not a hybrid. It’s a practical, comfortable, and somewhat sporty three-row SUV made for families who want reliability and a touch of luxury more than excellent gas mileage.

City and highway performance

The EPA estimates 20 MPG in the city and 27 MPG on the highway, showing the MDX’s balanced performance. In town, the 3.5L V6 offers plenty of power for acceleration, working smoothly with the nine-speed automatic transmission. The MDX never feels weak, even when full of people and stuff. This helps explain why the city MPG isn’t as good as the highway MPG. On the highway, the MDX is comfortable, the quiet engine easily keeps up speed and travels long distances efficiently. The taller gearing of the nine-speed transmission helps the highway number by lowering engine RPMs and gas use at higher speeds. It’s a good highway number for a vehicle this size and weight.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Acura MDX FWD is $2,500. This is based on driving 15,000 miles per year and the national average fuel price at the time. Your actual fuel costs may change depending on how you drive, the fuel you buy, and changes in fuel prices.

This number helps you compare the MDX to other vehicles and budget for its running costs.

Real-world expectations

EPA estimates are useful, but real-world fuel economy changes based on driving conditions and habits. MDX drivers who are mostly in city traffic may see their average MPG closer to 20 MPG, or even a bit lower. If you mostly drive on the highway, you might get more than 27 MPG, especially if you drive gently and use cruise control. Quick acceleration, hard braking, and heavy loads will all hurt fuel economy.

Expect the MDX to have fairly consistent fuel economy for its size, engine, and purpose. Learn more about MDX MPG across all years.

How it compares

The 2020 Acura MDX is in a popular group of luxury three-row SUVs, and its fuel economy is average for the class. The Lexus RX 350L gets an EPA-estimated 22 MPG combined, making it a bit less efficient. The Infiniti QX60 matches the MDX with 23 MPG combined.

The Volvo XC90 T5 FWD gets 25 MPG combined, mostly because of its smaller, turbocharged engine. Some buyers like the V6 in the MDX for its smooth power and known reliability. Across the Acura lineup, you can review all Acura fuel economy data. These fuel economy differences can add up to a significant cost over time, influencing some buyers.

Tips to maximize efficiency

Use the MDX’s “Econ” mode when you can, especially in the city. This mode changes throttle response and transmission mapping to improve fuel efficiency. It might slow acceleration a little, but the difference is often small, and the gas savings can be worth it.

Keep your MDX maintained based on the manufacturer’s service schedule. Regular oil changes, properly inflated tires, and a clean air filter all help engine performance and fuel efficiency. Ignoring these tasks can slowly lower your MPG.

Avoid fast acceleration and hard braking. Smooth acceleration and anticipating traffic can improve your fuel economy. The MDX’s nine-speed transmission is designed to manage the engine’s power efficiently, so let it do its job.

Avoid idling. If you’ll be stopped for more than a minute, turn off the engine. Modern engines restart quickly, and idling wastes gas. This is important in cities with frequent stops.

Check your tire pressure often. Underinflated tires increase rolling resistance, hurting fuel economy. See the sticker on the driver’s side doorjamb for the recommended tire pressure for your MDX, and keep your tires properly inflated.
