The 2019 Acura MDX AWD with the 3.5L V6 gets 22 MPG combined, which is respectable. This vehicle offers secure all-weather traction, a strong V6 engine, and three rows of seating in a luxurious package. MDX buyers aren’t typically chasing maximum fuel economy. They prioritize safety, reliability, and family-friendly features, accepting the fuel consumption as a trade-off for these attributes.
City and highway performance
The EPA numbers break down further to show the MDX achieves 19 MPG in the city and 26 MPG on the highway.
The city figure reflects the stop-and-go driving that large SUVs often face, hauling kids to school, running errands, and navigating congested urban environments. The slightly better highway figure points to the V6 engine’s efficiency at steady speeds, highlighting its ability to cruise comfortably on longer trips, even with a full load of passengers and cargo. The nine-speed automatic transmission (S9) helps keep the engine in its optimal rev range for efficiency at higher speeds. Those who spend most of their time on the open road will naturally see numbers closer to that 26 MPG rating.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2019 Acura MDX AWD at exactly $2,650. This figure is based on driving 15,000 miles per year, using national average fuel prices. While individual spending may vary depending on driving habits and local fuel costs, the $2,650 benchmark provides a standardized comparison against other vehicles in its class. It’s a useful data point to consider when budgeting for the overall cost of ownership.
Real-world expectations
While the EPA estimates provide a baseline, real-world fuel economy can differ. Aggressive driving, frequent short trips, and carrying heavy loads will all negatively impact MPG. Conversely, smooth acceleration, consistent highway speeds, and diligent maintenance can help drivers achieve numbers closer to the EPA estimates. Many drivers report seeing the stated combined MPG of 22 in mixed driving conditions. Monitoring the MDX’s trip computer and adjusting driving habits accordingly can substantially influence long-term fuel costs.
How it compares
Compared to its competitors, the 2019 Acura MDX’s fuel economy is competitive, though not class-leading. For example, the 2019 Lexus RX 350 AWD achieves slightly better fuel economy at 22 MPG city and 29 MPG highway. The RX 350 prioritizes fuel efficiency and comfort, but it only has two rows of seating and a less sporty driving feel.
The 2019 BMW X5 xDrive40i, with its turbocharged inline-six, manages 20 MPG city and 26 MPG highway, putting it on par with the MDX in highway driving but slightly better in city driving. The X5 boasts a more performance-oriented driving experience, although that comes at a higher price point. Buyers weighing the Acura against these competitors must balance the MDX’s blend of practicality, luxury, and value, alongside fuel efficiency. More information, including all Acura fuel economy data, can help in making this decision. You can also compare MDX MPG across all years.
Tips to maximize efficiency
Use the MDX’s “Econ” mode whenever possible. This setting optimizes engine and transmission settings for efficiency, softening throttle response and adjusting shift points. This is most beneficial during city driving and on relatively flat highway stretches.
Proper tire inflation is important. Check your tire pressures regularly and inflate them to the recommended levels listed on the doorjamb sticker. Underinflated tires increase rolling resistance, which reduces fuel economy.
Reduce excess weight. Avoid carrying unnecessary cargo in the vehicle. Extra weight forces the engine to work harder, consuming more fuel. Remove roof racks or cargo carriers when not in use, as they increase aerodynamic drag.
Practice smooth acceleration and braking. Avoid sudden starts and stops, as these waste fuel. Anticipate traffic flow and maintain a steady speed whenever possible. Gradual acceleration and gentle braking help the engine operate more efficiently.
Consider skipping AWD in the summer. If maximum fuel efficiency is your goal, understand that the MDX is also available in a front-wheel-drive configuration. This version offers nominally better fuel economy for a slight trade-off in all-weather capability.
