24 MPG combined may not be class-leading, especially for a front-wheel-drive compact luxury SUV like the 2022 Acura RDX with the 2.0L 4-cylinder. However, many RDX buyers are willing to accept this, understanding they are prioritizing a comfortable, well-equipped, and stylish vehicle over outright fuel efficiency. These buyers appreciate the RDX’s balance of practicality and premium features, and acknowledge that its fuel consumption is a reasonable trade-off for the driving experience and overall value.

City and highway performance

The EPA estimates the 2022 Acura RDX FWD 2.0L 4-cyl at 22 MPG in the city and 28 MPG on the highway. These numbers reflect the realities of different driving conditions.

The city MPG reflects the stop-and-go traffic and lower speeds typical of urban environments, which require more frequent acceleration and braking. The highway figure showcases the efficiency achievable at consistent cruising speeds with minimal acceleration. The 10-speed automatic transmission plays an important role, optimizing gear selection for both performance and fuel economy. Its wide ratio spread allows for brisk acceleration when needed while maintaining lower engine speeds at higher cruising speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Acura RDX FWD 2.0L 4-cyl to be $2,400. This calculation is based on driving 15,000 miles per year and using national average fuel prices.

It’s important to remember that this is just an estimate. Your actual fuel costs will vary depending on your driving habits, the type of roads you typically drive on, and, of course, fluctuations in gasoline prices. For instance, someone who primarily drives in congested city traffic will likely spend more than $2,400 per year, while someone who mainly uses the RDX for highway commutes might spend less.

Real-world expectations

While the EPA estimates provide a useful baseline, it’s important to consider real-world experiences. Some drivers find that their actual mileage closely mirrors the EPA figures, but some report slightly lower or higher numbers depending on their driving style and environmental conditions. Aggressive acceleration, frequent hard braking, and extended idling will all negatively impact fuel economy.

Conversely, a smooth and consistent driving style, coupled with proactive maintenance, can help you achieve or even exceed the EPA estimates. The RDX FWD’s MPG performance depends on the restraint, or lack thereof, of the driver.

How it compares

The 2022 Acura RDX FWD 2.0L 4-cyl’s 24 MPG combined sits roughly in the middle of its segment. The Lexus NX 350h, a hybrid, achieves a significantly better 39 MPG combined. However, that vehicle prioritizes efficiency above all else; the RDX aims for a balance between efficiency, performance, and a premium driving experience. The BMW X3 sDrive30i, another front-wheel-drive competitor, gets an EPA-estimated 25 MPG combined. Meanwhile, the Audi Q5 40 TFSI, despite having all-wheel drive, also achieves around 25 MPG combined. Buyers drawn to the RDX often cross-shop these vehicles, so understanding the nuances of their fuel economy is essential.

Tips to maximize efficiency

Use the RDX’s drive modes. The “Econ” mode optimizes engine and transmission settings for fuel efficiency, softening throttle response and prioritizing higher gears. While it might slightly reduce the feeling of responsiveness, it can noticeably improve your MPG during daily commutes, especially in stop-and-go traffic.

Pay attention to tire pressure. Underinflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel. Regularly check and maintain the recommended tire pressure, which is typically found on a sticker inside the driver’s side doorjamb. Properly inflated tires also improve handling and extend tire life.

Avoid unnecessary weight. Carrying extra cargo in your RDX increases the vehicle’s overall weight, impacting fuel consumption. Remove any unnecessary items from the trunk or cargo area to lighten the load and improve MPG. Even small weight reductions can add up over time.

Plan your trips efficiently. Combining multiple errands into a single trip can reduce cold starts, which are less fuel efficient. Avoid unnecessary detours or stops that add extra mileage to your journey. Efficient trip planning can save you both time and fuel.

Consider enrolling in RDX MPG across all years user forums and social media groups. You will be able to learn the real-world experiences of other RDX drivers. This can give you good insight into optimal driving practices for achieving maximum fuel efficiency, as well as what to expect given the variability of real-world driving conditions.
