23 MPG combined isn’t a headline-grabbing figure, but it’s the reality for the 2025 Acura RDX AWD with the 2.0L turbocharged four-cylinder engine. It’s a trade-off that RDX buyers accept. They prioritize a rewarding driving experience, generous standard features, and Acura’s reputation for reliability over segment-leading fuel efficiency. They want a comfortable and capable all-weather vehicle without sacrificing performance, and they understand that forced induction and all-wheel drive have a fuel economy penalty.

City and highway performance

The RDX’s EPA ratings break down to 21 MPG in the city and 27 MPG on the highway. The city figure reflects the demands placed on the 2.0L turbo in stop-and-go traffic. The relatively small displacement engine needs boost to deliver adequate acceleration from a standstill, and that translates to increased fuel consumption. The 27 MPG highway rating is more respectable and achievable on longer journeys, especially when using the adaptive cruise control system and maintaining a steady speed. The 10-speed automatic transmission helps keep the engine in its most efficient range at highway speeds, but aggressive passing maneuvers will quickly drop the MPG figure.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2025 Acura RDX AWD. This figure is based on driving 15,000 miles per year and using the national average fuel price for regular unleaded gasoline (as of the EPA’s calculation). Individual fuel costs will vary depending on driving habits, local fuel prices, and the actual number of miles driven annually. It’s a useful benchmark for comparison but should not be taken as a guaranteed expense. Drivers who primarily use the RDX for short commutes in congested urban areas are likely to exceed this annual cost, while those who frequently take long highway trips may find their fuel expenses are lower.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy tends to differ. RDX drivers report figures slightly below the official 23 MPG combined rating, often hovering closer to 20-22 MPG in mixed driving conditions. This is especially true for those who live in hilly areas or regularly use the Sport driving mode, which holds gears longer and prioritizes performance over efficiency. Factors like tire pressure, vehicle load, and ambient temperature can also subtly influence fuel consumption. However, conscientious drivers who adopt fuel-efficient driving habits can often match or even slightly exceed the EPA estimates, particularly on longer highway trips.

How it compares

The Acura RDX sits in a competitive class. The Lexus NX 350 AWD, for example, achieves 25 MPG combined, giving it a slight edge in fuel efficiency. The BMW X3 xDrive30i, another popular choice, mirrors the RDX’s 23 MPG combined. The Volvo XC60 B5 AWD achieves 25 MPG combined, adding pressure on the RDX in terms of fuel economy. While these rivals may offer comparable or slightly better fuel economy, the differences aren’t substantial enough to sway most RDX buyers who are drawn to Acura’s reputation for reliability and the RDX’s strong value within the premium compact SUV segment. This comparison is most relevant for buyers who are genuinely torn between multiple vehicles and place a high priority on minimizing fuel costs. Shoppers interested in comparing all Acura fuel economy data can compare the entire lineup.

Tips to maximize efficiency

Use the “Econ” driving mode, especially during city driving. This mode adjusts throttle response and transmission mapping to prioritize fuel efficiency, resulting in smoother acceleration and earlier upshifts. It might slightly dampen performance, but it can noticeably improve MPG in stop-and-go situations. This mode is designed for precisely these scenarios.

Regularly check and maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure and invest in a reliable tire pressure gauge. A small effort here translates to tangible fuel savings over time.

Minimize unnecessary weight in the vehicle. Excess cargo adds extra strain on the engine, reducing fuel efficiency. Remove any items from the trunk or rear seats that aren’t essential. A lighter vehicle requires less energy to accelerate and maintain speed, improving MPG.

Practice smooth and consistent driving habits. Avoid aggressive acceleration, hard braking, and excessive idling. Anticipate traffic flow, maintain a steady speed, and coast whenever possible. Gradual acceleration and smooth deceleration are key to maximizing fuel economy in any vehicle, especially those with turbocharged engines.

Consider using cruise control on long highway drives. Cruise control helps maintain a consistent speed, minimizing fluctuations in fuel consumption. However, be mindful of hills, as cruise control may downshift aggressively to maintain speed, negating some of the fuel-saving benefits. Use adaptive cruise control wisely, adjusting the following distance and speed settings as needed.
