21 MPG combined isn’t going to win any fuel-sipping awards, but the 2020 Acura MDX AWD A-SPEC with its naturally aspirated 3.5L V6 isn’t about maximizing efficiency above all else. It’s about delivering a satisfying blend of sporty driving dynamics, all-weather capability, and premium features in a three-row SUV. This configuration appeals to buyers who prioritize Acura’s respected engineering, sharp styling and solid performance over class-leading fuel economy.
City and highway performance
Looking more closely, the EPA estimates 19 MPG in the city and 25 MPG on the highway. The city rating reflects the engine’s displacement and the demands of stop-and-go driving, where the nine-speed automatic transmission (S9) is frequently shifting. The highway figure climbs to a more respectable 25 MPG when cruising at consistent speeds, showing the benefits of the transmission’s higher gear ratios. While some competitors use turbocharging or hybrid technologies to boost city MPG, the MDX relies on a proven V6 that prefers smooth, moderate throttle inputs for optimal efficiency. Drivers who accept the MDX’s fuel economy are primarily focused on highway mileage, since they are more likely to load the vehicle up with passengers and cargo for longer trips.
Annual fuel cost
According to EPA estimates, the annual fuel cost for the 2020 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 when the data was originally calculated. Keep in mind that this number will fluctuate based on your actual driving habits and current gas prices. Drivers who rack up significantly more than 15,000 miles annually, or those who live in areas with higher fuel costs, should expect to spend more. Conversely, those who drive less or live where fuel is cheaper will likely spend less on fuel per year. You can find all all Acura fuel economy data on this site.
Real-world expectations
While the EPA estimates provide a baseline, real-world fuel economy can vary depending on several factors. Driving style, terrain, weather conditions, and even tire pressure can all impact the MPG you actually achieve. Aggressive acceleration, frequent hard braking, and extended idling will all decrease fuel efficiency. Conversely, driving conservatively, anticipating traffic flow, and maintaining proper tire inflation can help you get closer to the EPA estimates, or even exceed them.
Premium fuel is recommended, but not required, and using regular fuel could slightly decrease your fuel economy and vehicle performance.
How it compares
The MDX’s fuel economy sits in the middle of the pack compared to its competitors. For example, the Volvo XC90 T6 AWD is rated at 20 MPG combined, the BMW X5 xDrive40i achieves 23 MPG, and the Audi Q7 45 TFSI Quattro gets 21 MPG combined. The Lexus RX 350 AWD manages 22 MPG combined, demonstrating a slight edge in fuel efficiency. The Infiniti QX60, generally considered the MDX’s most direct competitor, mirrors the MDX’s 21 MPG rating. The MDX’s combination of engaging driving dynamics, Acura’s reputation for reliability, and the A-SPEC’s unique styling justify the fuel economy numbers for many buyers.

Tips to maximize efficiency
Gentle acceleration is your friend. While the MDX’s V6 engine readily provides power, avoid abrupt acceleration and hard launches. Smooth, progressive throttle inputs will help the engine operate in its most efficient range, using less fuel to get up to speed.
Maintain a steady speed on the highway. Use cruise control whenever possible to avoid unintentional speed fluctuations. Minimizing sudden bursts of acceleration and braking is especially important at higher speeds, as aerodynamic drag significantly increases fuel consumption.
Keep your tires properly inflated. Check tire pressure regularly and ensure that they are inflated to the recommended pressure listed on the driver’s side door jamb. Underinflated tires increase rolling resistance, which reduces fuel economy.
Reduce unnecessary weight. Carrying excessive cargo in the MDX adds weight, which directly impacts fuel efficiency. Regularly remove unnecessary items from the vehicle to lighten the load and improve MPG.
Plan your routes wisely. Avoid congested areas and routes with frequent stop-and-go traffic. Using navigation apps to identify and avoid traffic delays can save fuel by minimizing idling and the constant acceleration/deceleration cycle often experienced in heavy traffic.
