The 2019 Acura MDX AWD A-SPEC, with its 3.5L V6, gets a combined EPA fuel economy rating of 21 MPG. That figure won’t win any awards, and it certainly isn’t the primary reason a buyer chooses this specific configuration of Acura’s popular three-row SUV. Instead, it’s a known quantity, a compromise accepted in exchange for the MDX’s blend of sporty aesthetics, confident all-wheel drive performance, and practical family hauling capabilities.

City and highway performance

Breaking down the 21 MPG combined figure reveals 19 MPG in the city and 25 MPG on the highway. The city rating reflects stop-and-go driving. The V6 engine, while smooth and responsive, requires more fuel when constantly accelerating from a standstill. The nine-speed automatic transmission (S9), while generally well-tuned, can sometimes hesitate in city traffic, further impacting fuel consumption. On the open road, the MDX fairs noticeably better. The engine settles into a more efficient cruising speed, and the transmission can more readily use its higher gears, contributing to the 25 MPG highway rating.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2019 Acura MDX AWD A-SPEC is $2,750. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Of course, real-world fuel costs will vary depending on individual driving habits, local fuel prices, and the specific type of fuel used. The $2,750 provides a useful benchmark for comparing the MDX’s running costs to other vehicles in its class.

Real-world expectations

While the EPA estimates provide a standardized measure, MDX A-SPEC owners have reported slightly different figures in their daily driving. Drivers who primarily drive in congested urban areas may see figures closer to the 19 MPG city rating, or even slightly below. Conversely, drivers who frequently take longer highway trips may achieve results closer to, or even above, the 25 MPG highway rating. Aggressive driving habits, such as frequent hard acceleration, will naturally decrease fuel economy, while smoother, more deliberate driving can help to improve it. Also, weather conditions and cargo will play a role.

How it compares

The Acura MDX’s fuel economy sits in the middle of the pack when compared to its key competitors. For instance, the Volvo XC90 T6 AWD, with its supercharged and turbocharged four-cylinder engine, achieves 22 MPG combined. The BMW X5 xDrive40i, with its inline-six, manages 23 MPG combined. The Lexus RX 350 AWD, a perennial favorite, posts 22 MPG combined. While these rivals offer slightly better EPA numbers, the discrepancies aren’t always significant in real-world driving. Some buyers may prioritize the MDX A-SPEC’s bolder styling and sportier driving dynamics over a marginal increase in fuel efficiency. Comparing MDX MPG across all years reveals that changes to the powertrain have played a role, as well as the addition of hybrid options.

Tips to maximize efficiency

Tire maintenance is often overlooked, but properly inflated tires can significantly impact fuel economy. Check your tire pressure regularly and ensure they are inflated to the recommended specifications listed on the driver’s side doorjamb. Underinflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel.

Aggressive driving habits, such as rapid acceleration and hard braking, are detrimental to fuel economy. Anticipate traffic flow, maintain a steady speed, and avoid unnecessary acceleration. The MDX A-SPEC’s responsive engine can be tempting, but a smoother driving style will result in noticeable fuel savings.

Avoid idling for extended periods. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and restarting the engine consumes less fuel than idling for a prolonged period. This is especially relevant in urban environments with frequent stoplights and traffic congestion.

Consider using the Acura’s “Econ” mode, if equipped. This mode adjusts the engine’s throttle response and transmission shift points to prioritize fuel efficiency. While it may slightly reduce performance, the impact on fuel economy can be worthwhile, especially during routine commuting. Explore all Acura fuel economy data to compare other models.
