23 MPG combined is the fuel economy for the 2022 Acura RDX AWD A-SPEC. This isn’t a hybrid, nor does it pretend to be. It’s a stylish, sporty crossover aimed at buyers who prioritize confident handling, a well-appointed interior, and the Acura brand over saving gas. They’re willing to trade fuel efficiency for the RDX’s blend of performance, luxury, and practicality.

City and highway performance

The EPA estimates the RDX AWD A-SPEC will achieve 21 MPG in the city and 26 MPG on the highway. These figures reflect the realities of urban driving, with its stop-and-go traffic and lower average speeds, versus the more consistent pace of highway cruising. The 2.0L turbocharged four-cylinder engine, paired with a 10-speed automatic transmission, works efficiently in both environments, but frequent acceleration and deceleration in the city inevitably lead to lower mileage. Buyers considering this specific trim and drivetrain should understand that their daily commute will significantly impact their overall fuel consumption, and the highway number is achievable only with conscious driving.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2022 Acura RDX AWD A-SPEC at $2,500. This figure is based on driving 15,000 miles per year and using the national average fuel price for premium gasoline, which is the recommended fuel for optimal performance in the RDX. It’s a useful benchmark, but remember that your actual fuel costs will fluctuate depending on your driving habits, the type of driving you do, and prevailing fuel prices in your area. Someone covering primarily highway miles will likely spend less, while a driver stuck in rush hour daily could easily exceed this estimate. And of course, fluctuations in fuel costs could quickly impact the sticker price.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world MPG often varies. Owners of the RDX AWD A-SPEC frequently report figures slightly below the official combined rating, particularly in colder climates or with aggressive driving styles. Expect somewhere in the 20-24 MPG range overall. The Acura’s SH-AWD system, while contributing to its confident handling in all weather conditions, also adds weight and mechanical drag, subtly impacting fuel economy. For a broader picture, you can review RDX MPG across all years.

How it compares

The Acura RDX’s fuel economy places it in the middle of the compact luxury SUV segment. The Lexus NX 350h hybrid achieves a better 39 MPG combined, but at a higher price point and with a different driving experience. The BMW X3 xDrive30i, another popular competitor, delivers around 24 MPG combined, very close to the RDX. The Audi Q5 45 TFSI achieves comparable numbers as well, around 25 MPG combined. The Volvo XC60 B5 AWD is rated at 25 MPG combined. Ultimately, the RDX’s fuel consumption isn’t a standout feature, but its other attributes justify the trade-off for many buyers.

Tips to maximize efficiency

Use the RDX’s drive mode selector. The “Econ” mode optimizes vehicle systems, including throttle response and climate control, to prioritize fuel efficiency. It might slightly dampen performance, but it can make a noticeable difference on longer drives.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and maintain the recommended levels listed on the driver’s side doorjamb.

Anticipate traffic flow and avoid hard acceleration and braking. Smooth, consistent driving habits are key to maximizing fuel efficiency in any vehicle, but especially in a turbocharged engine like the RDX’s. Using the adaptive cruise control, where appropriate, can also help maintain a steady pace.

Minimize idling. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, and idling wastes fuel unnecessarily.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and properly functioning spark plugs all contribute to optimal engine performance and fuel efficiency. Follow the maintenance schedule outlined in your owner’s manual.
