24 MPG combined in the 2019 Acura RDX FWD A-Spec isn’t going to win any hypermiling contests, but that’s not the goal of this particular configuration. Buyers choosing the front-wheel drive A-Spec model prioritize sporty aesthetics and a more engaging driving experience (compared to the base model) over maximum fuel efficiency. They’re willing to trade a few MPG for the unique styling and improved handling the A-Spec package provides, trusting that the turbo engine still provides adequate fuel economy.

City and highway performance

The Acura RDX FWD A-Spec earns an EPA rating of 22 MPG in the city and 27 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine idles and accelerates more. The highway rating showcases the 2.0L turbocharged four-cylinder engine’s potential when cruising at consistent speeds. Remember that these are EPA estimates and actual results depend heavily on driving style and conditions.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,400 for the 2019 Acura RDX FWD A-Spec. This calculation assumes 15,000 miles of driving per year, with a mix of city and highway miles, using the national average fuel price at the time of the EPA’s testing. Changes in driving habits and gas prices will change the annual fuel expenditure.

Real-world expectations

The EPA provides a benchmark, but real-world fuel economy often differs from those figures. Drivers who accelerate quickly or encounter traffic might see numbers closer to the low end of the EPA range, or even a bit below. However, drivers who drive gently and stick to highway driving can expect to meet or exceed the EPA’s highway rating. The A-Spec package may lead to a more aggressive driving style for some owners, having a negative effect on real-world gas mileage.

How it compares

Within the luxury compact SUV segment, the 2019 Acura RDX FWD A-Spec has its own fuel economy position. For example, the front-wheel drive Lexus NX 300 achieves a slightly better 25 MPG combined. The BMW X3 sDrive30i posts similar numbers while offering a different driving experience. Choosing the RDX A-Spec comes down to prioritizing its style, performance, and features, even if it means giving up some fuel efficiency compared to some rivals. You can review RDX MPG across all years for more insight on the model’s fuel consumption across different configurations and model years, or view all Acura fuel economy data to get a broader view of the brand’s efficiency.

Tips to maximize efficiency

Use the RDX’s Eco mode. This can soften throttle response and optimize transmission shift points. It may slightly reduce the vehicle’s sporty feel, but it helps fuel savings over time, especially in the city. This mode is easily accessible via a button on the center console.

Make sure your tires are properly inflated to the recommended pressure, found on the driver’s side doorjamb. Underinflated tires increase rolling resistance, lowering fuel economy. Regularly checking and keeping the correct tire pressure is a simple way to improve efficiency.

Avoid fast acceleration and hard braking. The RDX’s turbocharged engine delivers ample power, but using it carefully will improve fuel consumption. Smooth acceleration helps minimize fuel waste, and anticipating traffic and braking gently can reduce fuel consumption, especially in urban areas.

Reduce idling. If you’re stopped for more than a minute or two, turn off the engine. Excess idling consumes fuel without moving the vehicle. Modern engines restart quickly and efficiently, making this a good way to save fuel, like when waiting in parking lots or drive-thrus.
