23 MPG combined is typical for many all-wheel-drive luxury compact SUVs, and the 2022 Acura RDX accepts that reality. This isn’t a hybrid or an economy car. It’s a stylish and comfortable vehicle designed to deliver a premium driving experience with the added security of AWD. Buyers choose the RDX for its blend of luxury, technology, and Acura’s reputation for reliability. The fuel economy, while not exceptional, is simply part of the reason to buy it.

City and highway performance

The EPA estimates the 2022 Acura RDX AWD at 21 MPG in the city and 27 MPG on the highway. These figures reflect how well the 2.0-liter turbocharged four-cylinder engine, which produces 272 horsepower, performs. The ten-speed automatic transmission also helps, offering a wide range of gears to optimize both acceleration and fuel conservation. In stop-and-go city driving, the turbocharger works harder, leading to the lower MPG figure. On the open highway, with consistent speeds and less demand on the engine, the RDX can more closely approach its rated 27 MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Acura RDX AWD at $2,500. This figure is based on driving 15,000 miles per year and using the national average fuel price. Your actual fuel costs will vary depending on your driving habits, the type of driving you do, and what fuel prices are in your area. If you primarily drive in the city or have a heavy foot, you’ll likely spend more than $2,500 annually on fuel. But, if you primarily drive on the highway and practice efficient driving techniques, you may spend less. The EPA’s calculation is based on regular unleaded fuel, which Acura recommends for the RDX.

Real-world expectations

The EPA provides a standardized estimate, but real-world fuel economy can vary. Expect to see numbers within a few MPG of the official figures in most situations. Aggressive driving will naturally lower MPG, as will frequent short trips where the engine doesn’t have a chance to reach optimal operating temperature. Owners who value fuel efficiency and drive economically should be able to achieve numbers closer to the EPA’s highway estimate, even in mixed driving conditions. You can view RDX MPG across all years to look at owner reported numbers.

How it compares

The Acura RDX AWD faces strong competition in the luxury compact SUV segment. The BMW X3 xDrive30i offers a similarly engaging driving experience, achieves a slightly better 24 MPG combined. The Lexus NX 350 AWD comes in around the same at 24 MPG combined, although it offers a hybrid option that gets significantly better fuel economy. The Audi Q5 45 TFSI quattro also gets 25 MPG combined helping it stand out. These rivals offer similar performance and luxury features, so fuel economy is often a key consideration for buyers. The RDX often wins on value, offering a blend of features and performance for the price, which makes a slightly lower MPG acceptable to many.

Tips to maximize efficiency

The RDX’s ten-speed automatic transmission is designed to optimize fuel economy, so allow it to shift smoothly and avoid aggressive acceleration. Using the “Comfort” drive mode can improve fuel efficiency by prioritizing smooth throttle response and earlier upshifts. The RDX offers paddle shifters, but using them frequently can decrease fuel economy, as manually downshifting can lead to higher engine RPMs.

Ensure that your RDX’s tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker. Consider using low rolling resistance tires when it’s time for a replacement. While they may slightly compromise handling, they can noticeably improve fuel economy over the long run.

Minimize unnecessary weight. Carrying extra cargo in your RDX increases fuel consumption, so remove any items you don’t need. If you have a roof rack, consider removing it when not in use, as it can create aerodynamic drag and reduce fuel economy.

Plan your trips to avoid stop-and-go traffic whenever possible. Consistent highway driving is more fuel-efficient than navigating congested city streets. Use navigation apps to find the quickest and most fuel-efficient routes. Anticipate traffic patterns and adjust your driving accordingly to minimize braking and acceleration.

Regular maintenance is important for optimal fuel economy. Keep your engine properly tuned, change your oil regularly, and replace air filters as needed. A well-maintained engine runs more efficiently and consumes less fuel. See all Acura fuel economy data to see how maintenance plays a role in MPG.
