The 2024 Acura RDX AWD has a combined fuel economy of 23 MPG, a number that will likely satisfy, but not excite, the typical Acura RDX buyer. These buyers prioritize a comfortable, well-equipped, and subtly sporty crossover. Fuel economy, while important, is often secondary to Acura’s reputation for reliability, the nicely appointed interior, and the assured grip of all-wheel drive.

City and highway performance

The EPA estimates the 2024 Acura RDX AWD will achieve 21 MPG in the city and 27 MPG on the highway. The lower city figure is understandable, given the RDX’s turbocharger; stop-and-go traffic rarely allows the forced-induction engine to operate at its most efficient. The 27 MPG highway rating is respectable, although it suggests that extended high-speed cruising will require more frequent fuel stops than some competitors. Acura’s smooth-shifting 10-speed automatic transmission helps keep the engine in its optimal rev range, contributing to this highway number. This gearbox is a major advancement over the older transmissions that were used in Acura vehicles. Take a look at RDX MPG across all years to see how Acura has managed efficiency over time.

Annual fuel cost

The EPA projects an annual fuel cost of $2,500 for the 2024 Acura RDX AWD. This estimate is based on driving 15,000 miles per year, using the national average fuel price at the time of calculation. Individual fuel costs will vary depending on local fuel prices and personal driving habits. Drivers who primarily drive on highways may find their annual fuel cost comes in slightly under this estimate, while those primarily confined to city driving may exceed it. This number assumes regular gasoline, which is what Acura recommends.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs from the official numbers. Acura RDX owners report figures close to the EPA estimates, implying that the ratings are relatively accurate. However, aggressive driving, frequent short trips, and using the RDX’s “Sport” mode, which holds gears longer, will all negatively impact fuel consumption. Conversely, using the “Econ” mode and practicing smooth acceleration can help drivers achieve figures at or even slightly above the EPA estimates. Some drivers may find that purchasing higher grade fuel will increase their fuel economy, but it may not be enough to fully offset its increase in cost.

How it compares

The Acura RDX exists in a crowded segment, and its fuel economy is comparable to other all-wheel drive luxury crossovers. The Lexus NX 350h, a hybrid, achieves a significantly better 39 MPG combined. However, the NX’s hybrid powertrain has a different driving experience and a higher initial price. The BMW X3 xDrive30i delivers a comparable 24 MPG combined, while offering a sportier driving experience. The Audi Q5 45 TFSI Quattro also achieves 25 MPG combined, offering a blend of luxury and performance. The Volvo XC60 B5 AWD delivers 25 MPG combined with a mild hybrid system. For some buyers, the differences in fuel economy may be negligible compared to factors like brand preference, features, and overall driving dynamics.

Tips to maximize efficiency

Use the RDX’s “Econ” mode, which adjusts throttle response and transmission behavior to prioritize fuel efficiency. It may slightly dampen acceleration, but it can make a noticeable difference in fuel consumption, especially during city driving.

Avoid aggressive acceleration and braking. Smooth, gradual inputs are key to maximizing fuel economy in any vehicle, but especially those with turbocharged engines. Turbochargers tend to introduce less efficient use of fuel at rapid acceleration, so gradual acceleration is important.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder and consumes more fuel. Check your tire pressure regularly and inflate to the recommended level found on the door jamb sticker.

Minimize idling. If you anticipate a stop of more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, making it more fuel-efficient to turn off the engine than to let it idle. This especially matters if you are commonly stuck in city traffic.
