21 MPG combined is the reality for the 2022 Acura MDX AWD with the 3.5L V6, a figure that lands squarely in the middle of the luxury three-row SUV segment. It’s not a standout number, but it’s an acceptable trade-off for buyers who prioritize Acura’s reputation for reliability, a comfortable ride, and strong resale value over outright fuel efficiency. The MDX buyer is typically a family seeking a premium experience without venturing into the higher price brackets of European competitors.

City and highway performance

The MDX’s EPA ratings break down to 19 MPG in the city and 25 MPG on the highway. The city figure reflects the engine’s need to work harder in stop-and-go traffic, while the highway number is more indicative of its cruising capabilities. Acura’s tuning of the 3.5L V6 delivers adequate power, but it’s not designed to be a fuel-sipping engine. Highway performance feels relaxed and confident, with the 10-speed automatic transmission doing its best to keep the engine in its most efficient range.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Acura MDX AWD 3.5L 6-cyl to be $2,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, local fuel prices, and how often you use the MDX’s various drive modes. Consider this number a benchmark for comparison rather than an absolute prediction of your expenses.

Real-world expectations

While EPA estimates provide a standardized benchmark, real-world MPG can vary. Aggressive driving, heavy cargo loads, and consistent use of the MDX’s towing capabilities will undoubtedly lower your fuel economy. Conversely, gentle acceleration, anticipating traffic flow, and prioritizing highway miles can help you achieve figures closer to the EPA estimates, or even slightly exceed them. Owners report averaging around 22 MPG in mixed driving conditions, demonstrating that the 21 MPG combined rating is achievable with mindful driving habits.

How it compares

The MDX’s fuel economy positions it competitively within its segment. The Lexus RX 350 AWD achieves a slightly better 22 MPG combined, attracting buyers who prioritize luxury and fuel efficiency. The BMW X5 xDrive40i, while offering a more engaging driving experience, achieves a similar 21 MPG combined. The Volvo XC90 B6 posts 22 MPG combined, thanks in part to its smaller, turbocharged engine. The Infiniti QX60, another popular choice in this class, offers 21 MPG combined. The Acura holds its own, appealing to those who value its blend of reliability, features, and price. Compare MDX MPG across all years to see how this model measures up to past iterations.

Tips to maximize efficiency

The MDX’s Intelligent Variable Valve Timing and Lift Electronic Control (i-VTEC) system optimizes engine performance, but driving habits still make a difference. Use the Eco drive mode in less demanding situations to prioritize fuel efficiency. This mode adjusts throttle response and shift points to encourage a more economical driving style.

Ensure your tires are properly inflated to the recommended pressure, found on the driver’s side doorjamb placard. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Regular tire pressure checks are a simple way to improve your MPG.

Avoid unnecessary idling. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern engines, including the MDX’s V6, are designed to restart quickly and efficiently, saving fuel compared to idling. This is especially effective in city driving.

Reduce excess weight in the vehicle. Removing unnecessary items from the cargo area and rear seats can lighten the load, improving fuel economy. Every extra pound requires more energy to accelerate and maintain speed, so decluttering can yield noticeable benefits.

Consider enrolling in a driver awareness course. These courses often provide valuable insights into fuel-efficient driving techniques, such as smooth acceleration, anticipation of traffic conditions, and optimal use of cruise control on the highway.
