The 2024 Acura MDX AWD, equipped with a 3.5L V6 engine and 10-speed automatic transmission, achieves 21 MPG combined. It’s not a hybrid, and it doesn’t try to be. The MDX occupies a specific niche: three-row luxury for families who want reliability, a good driving experience, and plenty of technology, without necessarily prioritizing best-in-class fuel efficiency. The fuel economy is simply part of the cost.

City and highway performance

EPA estimates for the MDX are 19 MPG in the city and 25 MPG on the highway. The city figure reflects the MDX’s weight and the demands of stop-and-go driving, where the naturally aspirated V6 works harder to move the large SUV. The highway number is more respectable. The 10-speed automatic helps keep the engine operating efficiently at cruising speeds, and the MDX’s aerodynamic design helps reduce drag. Drivers who frequently take longer highway trips will see their fuel economy improve noticeably compared to those who mainly drive in urban areas.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Acura MDX AWD at $2,750. This is based on driving 15,000 miles per year and using the EPA’s projected national average fuel prices. This is a useful benchmark for comparing the MDX’s running costs to other vehicles, but your actual expenses will vary based on your driving habits and local fuel prices. Some drivers might spend less, and others more, depending on how and where they drive.

Real-world expectations

While EPA estimates provide a standardized benchmark, real-world MPG can vary considerably. Quick acceleration, frequent short trips, and carrying heavy loads will all negatively affect fuel economy. On the other hand, smooth driving, consistent highway speeds, and correct tire inflation can help you get closer to, or even slightly exceed, the EPA estimates. The MDX’s trip computer is a useful tool for monitoring your fuel consumption and finding areas where you can improve your driving habits.

How it compares

The Acura MDX isn’t the most fuel-efficient vehicle in its segment. The Lexus RX 350 AWD, for example, gets 24 MPG combined from its V6 engine. The Volvo XC90 B5, with its turbocharged and supercharged four-cylinder engine, achieves 25 MPG combined despite also offering all-wheel drive. Even the BMW X5 xDrive40i, with its strong inline-six, posts EPA figures similar to the RX350. These differences come from a mix of engine technology, transmission gearing, and subtle variations in aerodynamics. The MDX buyer often prioritizes Acura’s reputation for reliability and the MDX’s engaging driving dynamics over maximizing MPG.

Tips to maximize efficiency

The MDX’s V6 responds well to smooth, deliberate acceleration. Avoid rapid starts and hard braking, as these waste fuel and stress the drivetrain. Gentle and steady acceleration allows the 3.5L engine to operate more efficiently, especially in city driving.

Regular maintenance is critical for the best fuel economy. Be sure your MDX’s tires are inflated to the recommended pressure; this reduces rolling resistance and improves MPG. Also, follow the recommended service schedule for oil changes and other maintenance. A well-maintained engine operates more efficiently.

Use the MDX’s drive mode selector. The “Econ” mode prioritizes fuel efficiency by adjusting throttle response and shift points. The changes might subtly affect performance, but they can noticeably improve fuel economy in everyday driving. Consider using “Econ” mode in low-demand situations like highway cruising or gentle city driving.

Minimize idling. Letting the MDX idle for a long time, especially with the air conditioning running, consumes fuel. Instead of idling, turn off the engine if you expect a long wait. This simple action can save fuel, especially during daily commutes and errands. One exception is in very hot weather where the turbocharging system needs time to cool down.
