The 2024 Acura MDX FWD with the 3.5L V6 gets 22 MPG combined. This isn’t going to win any hypermiling awards, but it’s a perfectly reasonable figure for a comfortable, practical, and relatively sporty three-row SUV aimed at families who prioritize reliability and a touch of luxury over using less gas. The MDX buyer appreciates a well-engineered vehicle with a proven track record, understanding that certain compromises, such as fuel economy hovering around the low 20s, are part of the overall package.

City and highway performance

The EPA estimates for the 2024 Acura MDX FWD break down to 19 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go traffic, where the 3.5L V6 is constantly working to get the MDX’s weight moving. The highway number is more palatable, showcasing the effectiveness of the ten-speed automatic transmission (S10) in optimizing engine speeds for cruising. This split suggests the MDX FWD is best suited for drivers who spend a significant portion of their time on the open road, where the improved efficiency can help offset the lower city MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Acura MDX FWD at exactly $2,650. This figure is calculated based on driving 15,000 miles per year, with a specific percentage allocated to city versus highway driving, using national average fuel prices. This standardized approach allows buyers to directly compare the MDX’s fuel expenses against other vehicles they might be considering. A clear picture of the long-term financial commitment comes with owning this particular model.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy will vary depending on driving style, road conditions, and maintenance. Aggressive acceleration, heavy braking, and consistently carrying a full load of passengers and cargo will all negatively impact fuel efficiency. Tire pressure also plays a role. Ensuring tires are properly inflated reduces rolling resistance and improves MPG.

Regular maintenance, including oil changes and air filter replacements, helps the engine run optimally, further contributing to better fuel economy. Expect to see a range, potentially dipping below the EPA estimates in certain conditions and exceeding them on long, steady highway drives. Some MDX owners report averaging slightly above the combined EPA figure with careful driving habits.

How it compares

The Acura MDX FWD competes in a crowded segment of three-row SUVs. When comparing fuel economy, it’s important to consider the alternatives. The Volvo XC90 B5 FWD, for example, achieves a slightly better 25 MPG combined thanks to its turbocharged four-cylinder engine and mild-hybrid system. The Lexus RX 350 FWD also scores a 25 MPG combined figure, benefiting from its more efficient powertrain relative to the MDX. On the other hand, the Infiniti QX60, with similar engine displacement, achieves about 23 MPG combined. For those who are considering the Acura MDX for its fuel economy, it’s worthwhile to check MDX MPG across all years.

For a broader perspective, you can always compare all Acura fuel economy data. These fractional differences can add up over the lifespan of the vehicle, but buyers often prioritize other factors like driving dynamics, interior features and brand reputation.

Tips to maximize efficiency

Anticipate traffic flow and avoid sudden acceleration and braking. Smooth, gradual inputs on the pedals allow the engine and transmission to operate more efficiently, conserving fuel. The MDX’s ten-speed automatic is designed to optimize fuel economy, but it can only do so if you drive with a gentle foot.

Minimize idling. If you anticipate stopping for more than a minute, turn off the engine. Excessive idling consumes fuel without covering any distance. The MDX does not offer a start/stop system, so avoiding idling is even more critical to squeeze out every possible mile per gallon.

Use cruise control on the highway. Maintaining a constant speed helps to improve fuel efficiency. Set the cruise control to a reasonable speed, avoiding excessive speeds which reduces economy. The MDX’s adaptive cruise control system can also help maintain a safe following distance, further promoting smoother driving.

Remove unnecessary weight from the vehicle. Carrying heavy cargo increases fuel consumption. Clean out any unnecessary items from the trunk and passenger area. Extra weight forces the engine to work harder, which equates to more fuel burned.

Keep your tires properly inflated. Underinflated tires increase rolling resistance. It’s critical to check the pressure and keep it at the recommended level to help improve the MPG by reducing the amount of energy required to move the vehicle along the highway. Refer to the sticker on the driver’s side doorjamb for the correct tire pressure.
